The Main Parts of a Commercial HVAC System

Thu, 30 Apr 2026 14:46:18 GMT

In many commercial buildings, indoor comfort is expected to stay consistent throughout the day. When temperatures begin to drift or airflow feels uneven, attention often shifts to the HVAC system. These systems rely on a network of interconnected components working together. When one part begins to underperform, the impact can extend beyond a single area. In larger facilities, these shifts can also affect productivity, occupant comfort, and day-to-day operations. Having a clearer sense of how these parts of an HVAC system function together helps bring those connections into focus.

What Makes Commercial HVAC Systems Different?

Commercial HVAC systems operate at a scale that introduces additional coordination and control. Equipment must respond to changing occupancy levels, multiple zones, and extended operating hours across a single facility. Heating, cooling, ventilation, and controls are tied together within one system, and a change in one area can influence overall performance. These systems are often integrated into broader building operations, where consistency and reliability play a direct role in maintaining daily functions. This level of complexity affects how systems are designed, serviced, and monitored over time, particularly in buildings with specific operational or environmental considerations.

Core Components of a Commercial HVAC System

Heating Equipment

Heating systems in commercial environments are built to manage higher demands while maintaining consistent temperatures across multiple zones and operating conditions.

Cooling Equipment

Cooling systems regulate indoor temperature and humidity by removing heat, helping maintain stable conditions as occupancy and internal loads shift throughout the day. This becomes especially important in facilities with heat-generating equipment or high foot traffic.

Ventilation System (Air Distribution)

Ventilation systems move conditioned air throughout the building while introducing outside air as needed, helping maintain balanced airflow and consistent indoor conditions. Proper ventilation also plays a role in managing indoor air quality across shared commercial spaces.

Refrigeration Components

Refrigeration components circulate refrigerant through the system, allowing heat to be absorbed indoors and released outside as part of the cooling cycle. This continuous cycle supports consistent temperature control across the entire system.

Thermostats & Building Controls

Control systems coordinate HVAC operation by adjusting settings, monitoring performance, and maintaining consistent conditions across different areas.

Piping Systems

Piping networks move water and refrigerant between system components, supporting heat transfer and overall system function. These pathways connect major equipment and help maintain steady operation across the system.

Common Issues with Commercial HVAC Components

When performance begins to change, the cause often traces back to wear, airflow restrictions, or control inconsistencies within individual components. A failing compressor, blocked ductwork, or miscalibrated sensor can affect how the system operates.

Over time, buildup on coils, leaks in piping, or failing valves can reduce efficiency and place added strain on connected equipment. Because these systems are interconnected, a single issue can extend beyond its point of origin.

Routine inspections and timely repairs help identify concerns early. This approach supports stable operation and helps reduce unplanned downtime that can impact daily operations and long-term system reliability. Addressing issues early can also help manage operating costs and prevent larger system disruptions.

What are Condensing Boilers & How Do they Work?

Mon, 16 Feb 2026 15:51:30 GMT

Heating performance plays a major role in the operating costs of commercial facilities. When evaluating boiler upgrades, many facility managers encounter high-efficiency options designed to reduce fuel use and emissions. Understanding how condensing technology works can help you decide whether this approach aligns with your building’s heating goals and long-term budget plans.

What Is a Condensing Boiler?

A condensing boiler is a high-efficiency heating system designed to capture heat from the combustion process that traditional boilers release through the exhaust. When natural gas burns, it produces heat along with water vapor. In older systems, the vapor and its usable energy exit through the flue. Condensing technology cools those exhaust gases enough to reclaim that heat before discharge. The recovered energy is transferred back into the heating loop, improving overall fuel efficiency and long-term performance in commercial applications.

How Condensing Boilers Work

When fuel combusts inside the burner, hot gases move through a primary heat exchanger, where heat transfers to the circulating system water. That heated water travels through the building’s hydronic distribution network to serve space heating or process loads. Instead of venting high-temperature exhaust immediately, the system routes those gases through a secondary heat exchanger. As temperatures drop, water vapor in the exhaust condenses into liquid form. This phase change releases latent heat, which is captured and redirected back into the system before the cooler exhaust is discharged.

Key Components of a Condensing Boiler

Several integrated components help these systems reach higher efficiency levels in commercial settings. Each part serves a specific role in heat transfer, combustion control, and safe operation across varied load conditions.

Primary Heat Exchanger:

Transfers combustion heat to system water using corrosion-resistant materials.

Secondary Heat Exchanger:

Captures additional heat from exhaust gases during the condensation process.

Modulating Burner:

Adjusts firing rate based on heating demand to improve efficiency and reduce fuel consumption.

Condensate Drain and Neutralizer:

Directs and treats acidic condensate to ensure safe discharge and system protection.

Condensing Boilers vs. Non-Condensing Boilers

The main difference between condensing and non-condensing systems is how they handle heat recovery and exhaust temperature. Traditional boilers vent hot flue gases at much higher temperatures, allowing usable heat to escape through the chimney. Condensing models cool those gases to extract additional energy before discharge, which raises operating efficiency and lowers fuel consumption. In commercial heating, boilers often deliver more consistent hydronic heat than furnaces, and condensing technology further enhances performance, system longevity, and long-term cost control.

Benefits of Condensing Boilers for Commercial Buildings

High-efficiency boiler systems offer clear advantages for commercial facilities focused on cost control and operational performance. Condensing technology helps use fuel more effectively while maintaining steady heating output across varying load conditions throughout the year in demanding commercial environments.

Lower Energy Expenses: Better heat recovery reduces overall fuel consumption.

Reduced Emissions: Higher efficiency lowers carbon output per heating cycle.

Improved Load Matching: Modulating burners adjust output to match building demand.

Compact Footprint: Many units occupy less mechanical room space than older models.

Ideal Applications for Condensing Boilers

Condensing systems perform best in commercial environments that operate at lower return water temperatures for extended periods. These conditions let the unit remain in condensing mode longer, maximizing efficiency gains and lowering overall fuel consumption. Facilities with hydronic heating loops, radiant floor systems, snow melt applications, and high domestic hot water demand often see strong performance. Buildings that use variable air volume systems with reheat coils may also gain an advantage. A detailed system review helps confirm compatibility and projected efficiency improvements.

Installation Considerations for Condensing Boilers

Proper installation directly affects system performance, longevity, and efficiency. When commercial teams install a boiler , careful planning is needed to integrate new equipment into existing mechanical infrastructure, automation platforms, and building control systems for reliable long-term operation.

Venting Requirements:

Vent materials and sizing must meet manufacturer specs and code.

Condensate Management:

Drain lines and neutralizers are necessary to handle acidic discharge.

Water Quality:

Treatment may be needed to protect heat exchangers from scaling or corrosion damage.

System Compatibility:

Return water temperatures and distribution design influence overall efficiency.

Maintenance and Service Requirements

Routine service plays a major role in maintaining high-efficiency performance. Condensing equipment operates with tighter tolerances than older boiler systems, which makes scheduled inspections and cleaning especially important for reliable operation. Heat exchangers should be checked for buildup, burners inspected for proper combustion, and condensate drains cleared to prevent blockages. Control settings and safety devices also require periodic review and calibration. Consistent professional maintenance helps reduce unexpected downtime, stabilizes energy use, and extends equipment life in commercial facilities.

How Condensing Boilers Support Long-Term HVAC Performance

High-efficiency boiler technology contributes to stable, long-term HVAC performance in commercial facilities. Lower fuel consumption cuts operating expenses and eases strain on system components during peak heating periods. Modulating burners help maintain consistent temperatures, reducing short cycling and mechanical wear. When paired with a well-designed hydronic system, condensing boilers support even heat distribution and responsive controls. Over time, this leads to more predictable utility costs, fewer service interruptions, and more reliable comfort for occupants and staff.

Choosing Between CRAC and CRAH Units

Thu, 21 Aug 2025 15:11:01 GMT

Data centers depend on precise climate control to keep servers, storage devices, and networking hardware running at peak performance. Even minor temperature or humidity fluctuations can lead to system errors, downtime, or expensive equipment damage.

Two of the most common solutions for this type of environment are Computer Room Air Conditioning (CRAC) units and Computer Room Air Handling (CRAH) units. Both are designed for continuous operation and reliable cooling, yet their designs, energy usage, and infrastructure requirements differ.

Understanding how each option functions helps facility managers choose a system that fits their capacity, budget, and operational needs.

What Are CRAC Units?

A Computer Room Air Conditioning (CRAC) unit is a precision cooling system designed specifically for data centers and other mission-critical environments. These units operate similarly to traditional air conditioners, using a direct expansion refrigeration cycle to cool air before circulating it through the server room.

CRAC units typically contain compressors, condensers, and evaporator coils within a single enclosure. Air is drawn in, cooled by refrigerant passing through the evaporator coil, and then delivered back into the space at a controlled temperature and humidity level. Many models also have integrated humidifiers and dehumidifiers to maintain optimal environmental conditions.

Because CRAC units generate cooling independently, they do not require a separate chilled water supply. This makes them suitable for facilities without central chilled water plants or for operations seeking a self-contained system. They are often installed in smaller to medium-sized data centers, network rooms, and modular facilities where precise, localized temperature control is essential to equipment reliability.

What Are CRAH Units?

A Computer Room Air Handling (CRAH) unit is another precision cooling solution commonly used in large-scale data centers. Unlike CRAC units, CRAH systems rely on a building’s central chilled water plant to provide cooling. Instead of compressors and refrigerant cycles, they use cooling coils supplied with chilled water and fans to move air through the unit.

Warm air from the data center is drawn into the CRAH, passes over the cooling coils, and is then recirculated back into the space at the desired temperature and humidity. Because chilled water is the cooling medium, the CRAH unit itself consumes less electricity for cooling compared to a CRAC system. Energy use is mainly tied to the fan motors and controls.

These units are often favored in large data centers where chilled water infrastructure already exists, or in operations where maximizing efficiency is a top priority. They can also integrate easily into advanced building management systems, giving operators more control over temperature, humidity, and airflow patterns.

CRAC vs. CRAH: Key Differences

While both CRAC and CRAH units are built to maintain precise environmental conditions in data centers, they differ in how they generate cooling, their infrastructure needs, and how they perform in various settings. The table below outlines the most important distinctions:

These differences often determine which system is better suited for a given facility, especially when balancing budget, energy costs, and scalability goals.

Factors to Consider When Choosing a Unit

Existing Infrastructure. Facilities with a central chilled water plant may benefit more from CRAH units, while locations without one may find CRAC units easier to implement.

Energy Efficiency Goals. CRAH units typically offer higher efficiency in large-scale operations, but CRAC units can be more practical for smaller or modular setups.

Initial Investment vs. Long-Term Costs . CRAC units often have a lower upfront cost, while CRAH systems can yield greater energy savings over time in the right setting.

Cooling Load Requirements. Evaluate your current and projected cooling needs to choose a system that can handle peak loads without overconsumption.

Maintenance Capabilities. CRAC systems may require more frequent servicing of compressors and refrigerant components, whereas CRAH units rely on maintaining chilled water quality and pump systems.

Scalability . Consider how easily the system can expand to support future growth in IT infrastructure or additional data hall space.

Preventive Planning. Incorporating regular service and scheduling an HVAC annual inspection can help identify small issues before they impact system reliability.

How Chiller Systems Add Value to Commercial Spaces

Tue, 19 Aug 2025 16:38:49 GMT

For many commercial properties, temperature control isn’t just about comfort. It also protects equipment, preserves products, and keeps operations running smoothly.

Chiller systems play a key role in meeting these goals, providing reliable cooling for a wide range of facilities, including office towers, hotels, manufacturing plants, and data centers. The right setup can impact utility costs, employee productivity, and long-term maintenance needs.

Understanding what chiller systems do and how they operate helps business owners and facility managers make smarter investments. When designed, installed, and serviced correctly, they become an asset that supports both day-to-day operations and a company’s bottom line.

What Is a Chiller System?

A chiller system is a large-scale cooling solution that removes heat from a liquid, typically water or a water-glycol mixture. That chilled liquid is then circulated through equipment or air handlers to maintain comfortable indoor temperatures or keep machinery from overheating.

In commercial settings, these systems are often part of a central plant that serves multiple floors, zones, or even entire buildings. They are especially valuable in facilities where cooling loads are high, such as hotels, manufacturing plants, hospitals, and data centers.

These systems can be air-cooled or water-cooled, each suited to different building designs and operational needs. No matter the configuration, they are built to deliver consistent, reliable cooling at a scale most other HVAC solutions can’t match.

Types of Chillers

Chiller systems fall into three main categories: air-cooled, water-cooled, and heat pump chillers. Each type serves different building needs and operational priorities, and understanding the distinctions can help determine the most cost-effective and efficient choice for a facility.

The Basics of How Dehumidifiers Work to Control Humidity

Wed, 09 Apr 2025 15:04:16 GMT

Written by: 1 Source Mechanical

Excess moisture in the air can lead to mold growth, equipment deterioration, and uncomfortable conditions in commercial buildings. Maintaining proper humidity levels is essential for protecting assets, ensuring occupant comfort, and preserving indoor air quality .

Dehumidifiers serve a critical role in HVAC systems by extracting moisture from the air and helping maintain consistent environmental control. Understanding how these systems work is the first step in preventing humidity-related issues and optimizing performance in commercial spaces.

What is Humidity?

Humidity refers to the amount of water vapor present in the air. It is typically measured in terms of relative humidity (RH), which indicates the percentage of moisture in the air compared to the maximum amount the air can hold at a given temperature. Warmer air can hold more moisture, so relative humidity changes with both temperature and air pressure.

In commercial buildings, maintaining relative humidity between 30% and 60% is generally recommended. Levels above this range can create an environment prone to condensation, mold growth, and discomfort for occupants, while levels below can lead to static electricity, dry skin, and damage to materials like wood and paper.

Consequences of High Humidity in Commercial Settings

Uncontrolled humidity can create a range of challenges for commercial facilities. Elevated moisture levels promote the growth of mold, mildew, and bacteria, which can compromise indoor air quality and pose health risks to building occupants. These concerns are particularly critical in environments such as healthcare centers, office buildings, and hotels, where cleanliness and comfort are top priorities.

Over time, high humidity can also damage building materials. Wood may warp, metal can corrode, and insulation and drywall may deteriorate. In facilities that rely on sensitive electronics or machinery, moisture can cause malfunctions or lead to costly equipment failures.

Humidity also impacts energy efficiency. HVAC systems must work harder to regulate temperature when moisture levels are too high. This increases energy usage, raises utility costs, and shortens the lifespan of mechanical systems.

The Basics of Dehumidifiers

A dehumidifier is a mechanical device that reduces moisture levels in the air to support healthy indoor environments. In commercial HVAC systems, dehumidifiers may operate as standalone units or work in coordination with the larger system to control humidity in targeted zones.

The process starts when air enters the unit and passes over a set of cold evaporator coils. As the air cools, water vapor condenses into liquid and collects in a drain pan or is removed through a drainage line. The drier air is then reheated and circulated back into the space.

This moisture removal process helps protect building materials, equipment, and air quality, especially in areas with high occupancy or continuous moisture generation.

Types of Dehumidifiers

Commercial dehumidifiers are available in several configurations, each designed to address different building layouts, moisture loads, and performance requirements.

Refrigerant (Mechanical) Dehumidifiers
These units use a refrigeration cycle to cool incoming air, causing moisture to condense and separate from the airflow. They are effective in environments where the ambient temperature is moderate to warm and are commonly used in office buildings, retail spaces, and storage areas.

Desiccant Dehumidifiers
Desiccant systems use a moisture-absorbing material, such as silica gel, to extract water vapor from the air. These units are well-suited for colder environments or applications where very low humidity levels are required. They are often found in industrial settings, warehouses, and manufacturing facilities.

HVAC-Integrated Dehumidifiers
Some commercial HVAC systems include integrated dehumidification capabilities. These systems manage temperature and humidity through coordinated airflow control and moisture removal, offering seamless operation without the need for standalone units.

Each type serves a distinct purpose and can be selected based on the demands of the specific commercial space.

Key Components of a Dehumidifier

Commercial dehumidifiers are built with several essential components that work together to extract moisture from the air and support consistent humidity control.

Evaporator Coil
The evaporator coil cools incoming air. As warm, moist air moves across its surface, the temperature drops, and moisture condenses into liquid form.

Condenser Coil
Once moisture is removed, the air passes over the condenser coil, where it is reheated before being returned to the indoor space. This step helps maintain a comfortable temperature.

Compressor

The compressor drives the refrigeration cycle by pressurizing the refrigerant and enabling heat exchange between the evaporator and condenser coils. It is a central part of the dehumidification process.

Fan or Blower
Fans move air through the system, drawing it across internal components and distributing treated air back into the environment. Proper airflow is critical to effective operation.

Drainage System
Water collected during the condensation process must be removed efficiently. Commercial units typically use a gravity drain or pump to route water away from the system and prevent buildup.

Selecting the Right Dehumidifier for Your Commercial Space

Choosing the right dehumidifier depends on several factors unique to each facility. System selection should account for moisture load, operating environment, HVAC integration, and accessibility for maintenance.

Capacity Requirements
Dehumidifiers are rated by the amount of moisture they can remove over a 24-hour period. Facilities with high humidity levels, expansive square footage, or continuous moisture generation will need a unit with higher capacity to maintain proper conditions.

Environmental Conditions
Ambient temperature and airflow patterns influence system performance. Desiccant dehumidifiers are better suited for cooler environments, while refrigerant-based models often provide greater efficiency in warm, humid spaces.

Integration with HVAC Systems
Some commercial buildings benefit from dehumidifiers that integrate directly with the HVAC system. This setup supports centralized control and consistent airflow management, particularly in multi-zone facilities or where mechanical space is limited.

Maintenance Accessibility
Routine access for service, filter replacement, and drainage management should be factored into the selection process. Equipment installed in hard-to-reach areas may lead to inconsistent upkeep and reduced performance over time.

Maintenance and Best Practices

Routine maintenance keeps commercial dehumidifiers running efficiently and helps prevent unexpected breakdowns. A well-maintained system supports consistent humidity control and extends the life of the equipment.

Filter Cleaning and Replacement
Air filters should be inspected regularly and replaced as needed to prevent airflow restrictions and maintain indoor air quality. Dirty filters can reduce system efficiency and put unnecessary strain on internal components.

Coil Inspection
Evaporator and condenser coils must remain clean and free of debris. Dust buildup can insulate the coil surfaces, reduce heat transfer, and lower overall performance. Periodic cleaning ensures consistent operation.

Drainage System Checks
Clogged or misaligned drains can lead to water leaks, overflows, or microbial growth. Drain lines and pans should be inspected to confirm proper flow and prevent moisture buildup in or around the unit.

Electrical and Mechanical Review
Wiring, connections, fans, and compressors should be checked for wear or irregular operation. Early detection of loose parts or electrical issues can prevent costly downtime.

Scheduled Professional Service
Partnering with a commercial HVAC provider like 1 Source Mechanical for scheduled inspections and tune-ups helps identify minor issues before they become major problems. Regular service also supports warranty compliance and long-term system performance.

Key Takeaways

Uncontrolled humidity can lead to equipment failure, structural damage, and poor indoor air quality. A well-chosen, properly maintained dehumidifier helps protect your commercial space and supports efficient system performance.

Why Your AC Smells Funny: Types of Odors Explained

Fri, 28 Feb 2025 16:11:32 GMT

Written by: 1 Source Mechanical

There are several common air conditioning problems that can vex a building owner, but the unwanted odor is one of the more obnoxious ones. Sometimes, AC odors indicate that your unit needs routine service, but often, they are caused by a more urgent problem. That’s why it’s important to understand the various types of odors and to know what to do when you encounter one.

Common Types of AC Smells

One of the most common odors is a dusty smell, and it often occurs at the beginning of air conditioning season when the system hasn’t been used for a while. As long as it goes away in a few days, it’s generally nothing to worry about. It is just the dust that’s accumulated in the system.

However, many other odors do require your attention. Here are some that you might notice.

Rotten Eggs

If you notice the sulfur smell you associate with rotten eggs, you may have a gas leak. This can be serious and requires immediate action. Shut off your gas, get everyone out of the building, and call 911. Even a minor exposure to gas is a health hazard. Continued exposure can render you unconscious and even kill you.

Burning

As with the rotten egg odor, this is an emergency situation. Shut off your HVAC system, call 911, and evacuate. Possible causes include an overheated motor, frayed wiring, and other mechanical issues, but the first priority is to learn whether there is a fire and get it extinguished.

Dirty Feet

If your AC is emanating an odor reminiscent of a basket full of dirty sweat socks, there’s a good chance you have bacteria growing on your evaporator coils. This is a performance issue for the evaporator as well as an obnoxious odor for you. You’ll need to contact an HVAC professional to have those coils cleaned and sanitized.

Gunpowder

Some people describe this smell as resembling automotive exhaust. A common cause is a fluid leak where the fluid is dripping onto the motor or some other hot component. This sort of fume may be toxic, and you will need an HVAC pro to take care of it right away.

Mold

A musky, damp odor means you probably have mold or mildew somewhere in your system’s interior. There is a lot of condensation in a working AC, and if the moisture doesn’t properly drain, it can escape into the ducts and allow mold to form. Mold is unhealthy for respiration but is not a threat to most people in the very short run. Unless you have someone with asthma or allergies who is particularly sensitive, you can continue to run your system until your appointment with your HVAC professional. It’s still important to locate and remove the mold quickly to safeguard everyone’s health.

Cigarettes

If you smell cigarettes, the source of the odor is, in fact, tobacco. Someone has been smoking near the unit or the vents, and residue has built up inside the air conditioner. The source could also be someone smoking near an outside vent. Put a stop to the smoking, and the odor will diminish.

Garbage

If your system has a garbage smell that makes you think something crawled inside and died, that’s probably exactly what happened. Critters like mice, rats, and raccoons will often take shelter when it’s cold, and they don’t always make it out before the weather warms. Shut off the AC, open your windows, and call an HVAC pro or a pest control expert.

Reasons for Smelly Air Conditioners

Some of the reasons are the ones described above, including gas leaks, fluid leaks, overheated motors, condenser coils dirty with bacteria, and even dead animals in the system. However, many are problems that can be addressed by routine maintenance. For example, as the AC runs, water falls into the drain pan directly under the evaporator coils. Sooner or later, the pan needs to be replaced to prevent mold growth. There’s also a condensate line that runs from the pan into the landscaping and can accumulate buildup if it’s not kept clear. In addition, as the unit absorbs indoor air, removes humidity, cools the air, and pumps the air via the vents, the filters have to be clean for this to happen properly. Sometimes, the root cause is as simple as a clogged filter.

Can I Fix the Scents Myself?

It’s best to have a professional diagnose and correct the problem. However, there are some things you can do to mitigate the odor while you’re waiting for your HVAC expert to visit. The first step is to clean or replace any filters that haven’t been attended to for a while. Also, you can check to see whether the drain pan is full. If so, empty it, and it’s also a good idea to clean it with soap and water to get rid of any trace of mold that may have started.

When to Call HVAC Professionals

If you smell rotten eggs or something burning, call 911 and get the emergency problem taken care of first. For other odors, call an HVAC professional and get the issue resolved as quickly as possible. Even if you’ve changed filters and emptied the drain pain and the odor has diminished, you still should call and find out whether there’s a continuing problem.

Of course, the best time for HVAC service is before any odor occurs. Regular maintenance, including inspection, tune-ups, and balancing , will extend the life of your system and reduce the probability that smelly issues will arise.

Written by: 1 Source Mechanical

The heating, ventilating, and air conditioning (HVAC) system is the cornerstone of virtually any commercial environment. It's what not only regulates the temperature in a space, but that creates a comfortable area for people to live and work as they need, too.

One of the most important elements of such a system is the type of refrigerant used for the equipment itself. Understanding more about HVAC refrigerant, what it is, and why it matters is the key to fully appreciating the hard work that your system is doing daily.

What is an HVAC Refrigerant?

In a broad sense, the refrigerant in an HVAC system is used to transfer heat during the refrigeration cycle. It absorbs heat from the outdoor air, at which point that cool air can be released indoors. An HVAC system would be unable to function without it.

How HVAC Refrigerants Work

How HVAC refrigerants work will vary slightly depending on exactly which type of refrigerant you're talking about. In a general sense, though, the refrigerant will work in a continuous cycle with four main processes.

The first of those is evaporation , which is where the refrigerant absorbs heat from indoor air and evaporates. It will turn into a gas that then flows through the HVAC system's evaporator coil.

At that point, the refrigerant becomes highly pressurized and hot. That gas will then travel to the system's condenser coils, where the heat is released to the surrounding area. The refrigerant will start to cool, at which point it will turn back into a liquid.

That liquid will then pass through an expansion valve, which will reduce the pressure. Once the refrigerant has returned to its original state, the cycle will repeat for as long as the system is operational.

Types of Refrigerants

There are a few different types of refrigerant to choose from depending on your needs. They include but are certainly not limited to examples like the following.

R-12

This is a type of refrigerant that is commonly used in older HVAC systems. It has actually been phased out of use in most cases, as it has the potential to deplete the Ozone Layer and cause other environmental harm.

R-22

This is a type of refrigerant that is commonly used in air conditioners and heat pumps. It also has an environmental impact, but might still be needed sometimes when repairing older equipment.

R-134a

This is a type of refrigerant that is traditionally used in automotive air conditioning systems. It was originally introduced as a direct replacement for R-12 mentioned above.

R-290

This is a type of natural refrigerant, which is typically used in smaller refrigeration and air conditioning systems. This is a type of refrigerant that you'll most commonly see in Europe.

R-407c

This is an option that was designed as a replacement for R-22 in existing HVAC systems as needed.

R-410a

This is a commonly used type of refrigerant that is great for both residential and commercial HVAC systems due to its high energy efficiency.

R-450a

This is often looked at as something of a "transitional refrigerant." That is to say, it's better than what was previously available and will work until something new arrives.

R-450b

Originally developed as a replacement for R-22 in commercial HVAC systems, this is also being used as a traditional refrigerant.

R-454b

This is a newer type of refrigerant that was intended for use as a replacement for R-410a in many commercial situations.

R-513a

This is a type of refrigerant that is newer and is commonly used in commercial applications.

R-600a

This natural refrigerant is typically used in smaller refrigeration units. You'll see it used quite a bit in household refrigerators, for example.

Environmental Impact of HVAC Refrigerants

As mentioned above, refrigerants like R-12 and even R-22 have been proven to directly contribute to the depletion of the Ozone Layer. Because of this, refrigerants are often weighed against environmental considerations like their Ozone Depletion Potential, otherwise known as their ODP for short.

Other metrics that are used to rate a refrigerant include their Global Warming Potential or GWP, as well as their overall energy efficiency. Energy efficiency is particularly important, as it conveys the environmental impact a refrigerant has against its overall ability to efficiently transfer heat and otherwise perform as intended.

Proper Maintenance of HVAC Refrigerants

One of the biggest steps to take toward the proper maintenance of HVAC refrigerants has to do with checking for leaks in your equipment whenever possible. You can do this using not only electronic leak detectors but other processes like dye testing as well. It's important to note that even what initially appears to be a small leak can have a big impact on not only the overall efficiency of a commercial HVAC system but on the surrounding environment as well.

Equally important is the regular maintenance of all HVAC components. This includes but is not limited to the compressor, the condenser, the evaporator coils, and more. In addition to the use of high-quality refrigerant itself, all this goes a long way towards making sure the system is functioning properly and that it lasts as long as possible.

When servicing a commercial HVAC system, the importance of proper disposal of refrigerant cannot be overstated. Used or expired refrigerants should be disposed of responsibly according to local environmental regulations. Many refrigerants require specialized handling and recycling to prevent harm to the environment. Failure to do so could lead to significant penalties and can even be dangerous depending on the situation.

Basics to Benefits: What Are Building Automation Systems?

Wed, 18 Dec 2024 18:37:28 GMT

Written by: 1 Source Mechanical

A building automation system (BAS) can make a commercial building more comfortable, reduce operating costs, and increase the longevity of the HVAC and other utility components. But just what are building automation systems? Also, how do they work, and what can they do to improve the way you operate your facility?

What is a Building Automation System (BAS)?

A BAS automatically controls energy, safety, and utility systems across one or more buildings. These systems might include HVAC, electricity, water, lighting, security, and ventilation. These can be integrated so that the regulation of all these systems is coordinated and managed from a single integrated console. A facility with advanced integrated automated systems is sometimes called a smart building.

How Do Building Automation Systems Work?

A BAS uses sensors to monitor the building's utilities. It can detect things such as temperature, humidity level, air quality, and occupancy levels. It uses this feedback to adjust HVAC, lighting systems, and security systems. It may also provide alerts when some sort of human intervention is required. It coordinates the system's actions so that, for example, the temperature is not changed without considering all the other building controls.

Is Building Automation New?

No, it isn’t. It’s as old as the thermostat, which was first used in a school classroom in the 1880s. What is relatively new is the development of more and better monitoring and control systems and the integration of these systems so that they all work together and can be controlled centrally.

What Building Systems Can Be Automated?

HVAC systems are the oldest and perhaps most obvious candidates for automation, but the use of BSA doesn’t stop there.

HVAC

The thermostat is the first line of HVAC automation, but there’s much more to automated HVAC. A BAS also uses sensors to monitor humidity and other environmental factors. It can then adjust for the best balance of comfort and energy efficiency using real-time data. Some systems even consider occupancy, time of day, and outdoor weather conditions.

Lighting

Automated lighting systems can adjust light brightness and in some cases open and close shutters and blinds. As inputs, they use occupancy level, time of day, and sensors that detect the actual lighting level.

Security

Security systems manage authorized access issues such as who can enter the building and who can visit specific areas within the facility. This includes key card access, video surveillance, and alarms. A security system can engage and disengage enhanced security to more severely restrict after-hours access. It also manages building physical security by monitoring for fire, smoke, structural damage, and carbon monoxide. It might include a fail-safe mechanism to shut off dangerous equipment that is malfunctioning or is threatened.

Sanitizing Systems

Automated sanitizing systems might monitor airflow and air quality, and then adjust or raise an alarm as required. They also ensure that sterilizing units are functioning properly in any building where those devices are in use.

What are the Benefits of Building Automation?

Building automation systems have several benefits , and when you add them all together, it may not take as long as you'd think for the financial benefits to pay for the cost of installation.

Lower Energy Costs

When HVAC usage is being managed by BAS, you avoid unnecessary heating and cooling of the entire building. Moreover, when a smart HVAC monitors rooms individually and delivers cool air and heat accordingly, you don’t waste energy heating and cooling low-use rooms or overheating rooms when they’re highly occupied. Some systems will automatically open and close shades based on temperature and lighting to reduce energy costs. Also, many automated systems will produce data that can be analyzed for cost-saving opportunities .

Lower Operating Costs

BAS can also lower costs that are indirectly dependent on energy usage. For example, reduced lighting use lowers the cost of replacing bulbs. Air quality improvement can reduce cleaning costs and also reduce the cost of absenteeism.

More Flexibility

Building automated systems are able to adjust conditions in rooms where the occupant density changes. Some can proactively lower the heat or increase AC when a crowd gathers. In addition, there are automated systems that include a scheduling function. These can reserve conference rooms and be prepared to adjust conditions based on attendance.

Longer Lifespan of Systems

An HVAC system that is working no harder than necessary is one that you can expect to last for a long time . Furthermore, a system that is operating at a controlled level is less likely to develop problems. And, with systems that provide data on their performance, it’s often possible to identify small problems before they become large ones. Small problems can usually be resolved with no impact on the longevity of the system, but, if they go unrepaired, that’s likely not to be the case.

Consistent Comfort Levels

The health, comfort, and safety of the building’s occupants is a priority for most building owners. A consistent temperature and humidity keep folks active and productive. A facility with proper airflow and quality air, free of dust, pollen, and other pollutants, makes for a healthy workforce.

Streamlined Maintenance

With a BAS, you’re less likely to incur as much time and expense in diagnosing and resolving problems. That’s because an automation system often deals with minor problems without human intervention. It also detects problems earlier so that repairs are smaller and less costly. Then there’s the centralized monitoring capability, which frequently allows just an operator and one technician to deal with anything that comes up.

Insider’s Guide to the HVAC Refrigeration Cycle

What is a Refrigeration Cycle?

From a user’s perspective, air conditioning is simple. You set the thermostat, and cool air comes out when the indoor temperature goes above the target. But have you wondered what goes on behind the scenes? As it turns out, AC operates through something called the refrigeration cycle .

The HVAC refrigeration cycle consists of four processes that pipe refrigerant through the system. The components of the cycle control the temperature and pressure of the refrigerant, and thus control its energy level, as it passes from one component to another. When the refrigerant is hot, its energy level is high, and it’s ready to release heat. When the refrigerant has been cooled, its energy is low, and that’s when it can absorb heat and cool a room.

The Principles of Thermodynamics

The refrigeration cycle works because of the principles of thermodynamics. Thermodynamics is the science that describes the transfer of energy from one form to another. Heat is one of these forms of energy.

There are four laws of thermodynamics.

The Zeroth Law: What Temperature Really Means

At one time, only three laws had been described, but then a new one was added. Since all the other laws depend on it, it didn’t seem right to call in number four. That’s why it’s the zeroth law.

It states that when two systems are in thermal equilibrium with a third, the two are in equilibrium with each other. In other words, if room A and room B are both the same temperature as room C, then A and B are the same temperature as each other. That may sound obvious, but it’s important because it defines temperature as something that can be measured. It makes thermometers meaningful.

The First Law: Energy Can’t Appear Out of Nowhere

This is also called the law of conservation of energy. It says that energy is never created or destroyed, but can only be converted from one form to another. It takes energy to heat refrigerant in a system, and that energy is transferred into the refrigerant and increases its energy level. When the refrigerant cools, its energy is transferred into another form.

The Second Law: Heat Moves from Hot to Cold

This is something we all know, but the second law makes it explicit. If you put an ice cube in a glass, the ice melts because warmer air moves into it. The air in the glass doesn’t freeze. In air conditioning, warm air in a room moves into the colder refrigerant. If the refrigerant is then pressurized so that it becomes warmer, when it gets outside, its heat is released into the cooler outside air.

The Third Law: Nothing Moves at Absolute Zero

Warmer molecules, whether of air, refrigerant, or some other substance, move around more than molecules in a cold medium. There really isn’t any such thing as cold; cold simply describes the absence of heat.

Absolute zero is the condition where there is no heat at all and molecules don’t move. Getting something to absolute zero is impossible because there’s always something warmer touching it with heat that can move in.

How Does the Refrigeration Cycle Work?

Refrigerant is piped through four components – the compressor, the condenser, the expansion valve, and the evaporator. These control when the fluid absorbs heat and when it releases it. The cycle absorbs heat when it cools the interior of a building, and it releases heat when it releases cool air into the outside atmosphere.

The Compression Process

The compressor is the heart of the refrigeration cycle; it pushes the refrigerant through the system. It takes in cool, low-pressure gas refrigerant and compresses it into an extremely hot and high-pressure vapor. There isn’t any heat exchange with the indoor or outdoor air at this point, the compressor is preparing the refrigerant to make the circuit. It takes more power to run the compressor than any other component.

The Condensation Process

Next, the condenser cools the refrigerant and turns it into a liquid. Warm air from outside blows across the condenser coil, which is filled with hot refrigerant gas. The heat from the coil moves to the cooler outdoor air and diffuses into that air. The coil twists and winds through the condenser to maximize the surface area so it can transfer as much heat as possible. The condensation process turns the refrigerant from a gas into a hot, pressurized liquid.

The Expansion Process

The expansion device exists to reduce refrigerant pressure. It’s a step that’s required to prepare the refrigerant for evaporation. It drops the pressure so rapidly that the hot, high-pressure liquid refrigerant is converted into a combination of cold liquid and vapor.

The Evaporation Process

This is where the AC creates the cold air that will actually be forced into the rooms. It boils the refrigerant as it flows through. The building’s warm blows across the evaporator at the same time the cold refrigerant is moving through the evaporator coils. As in the condenser, the coils twist and wind to maximize surface area and heat transfer. Heat moves from the air to the refrigerant so that the air becomes cooler. This cooled air is what gets vented into the room. In the process, the low-pressure liquid refrigerant gets boiled, and the result is a cool, low-pressure vapor that goes back to the compressor and completes the cycle.

Boiler vs Furnace: Key Differences Explained

Tue, 22 Oct 2024 19:41:50 GMT

Written by: 1 Source Mechanical

People sometimes use the words “boiler” and “furnace” interchangeably. After all, they are similar: they both heat commercial buildings. However, boilers and heaters are two separate types of heating systems, and there are differences in costs, maintenance, heat quality, and heating efficiency. When considering boiler vs furnace, which is right for you? That depends on your building and your heating requirements.

What is a Boiler?

A boiler system heats with water or steam . The water is heated with gas, oil, or electricity until it is extremely hot, then it is piped to radiant flooring systems, cast iron radiators, or baseboard radiators throughout the building. Rooms are radiantly heated, so there are no fans and no ductwork.

What is a Furnace?

A furnace heats with hot air. It runs on oil, natural gas, propane, or electricity. A strong fan pulls air into the furnace where it crosses a heating element or heat exchanger. The heated air is then circulated throughout the building through ductwork with a blower. Heat is delivered into the rooms at vents and registers.

Differences Between Boilers and Furnaces

The basic difference between the two is that a boiler heats with hot water or steam, and a furnace uses heated air. Boiler water is heated in a tank, and furnace air is heated when it crosses a heating element or heat exchanger. A boiler distributes the heated water or steam through pipes, while a furnace’s hot air is blown through ductwork. Boiler water heat is distributed into the rooms at radiators and/or radiant flooring systems. Furnace warm air heat enters through registers and vents.

Maintenance

To maintain heating efficiency and maximize useful life, both types of systems should be professionally maintained at least annually. Maintenance is also a safety consideration for furnaces, as it reduces the risk of carbon monoxide poisoning through natural gas leaks.

Furnaces have filters that need to be changed monthly or quarterly, depending on how dusty or full of particulates the air is. Boilers have no maintenance requirements beyond annual service .

Heating

Furnace heat, because it is forced with a blower, can sometimes be dry and uncomfortable. Most people prefer the air quality of boiler heat. On the other hand, a building with a furnace comes to thermostat temperature more quickly. Boilers take longer to raise the internal air temperature when the thermostat is set higher.

Cost

The initial cost of a furnace is usually lower, and it takes much less time to install than does a boiler. However, boilers tend to run more efficiently. If you keep your heating unit for a long time, the lifetime cost of a boiler can be less.

Energy Efficiency

One way to compare the two is with the Annual Fuel Utilization Efficiency (AFUE) ratings. The most up-to-date high-efficiency furnaces have AFUE ratings of 85 percent or better. Boiler AFUE is more variable, at 80 percent or higher, depending on the fuel source and whether it’s a water or steam boiler. In general, boilers are more efficient because it takes less energy to heat water than it does to heat air.

Pros and Cons of Boilers and Furnaces

In favor of furnaces:

The time and cost to install furnaces are generally lower.
Because furnaces don’t use water, there’s less chance of a freeze during a winter power outage.
Any kind of water leak from a boiler has the potential to cause extensive damage.
Although furnaces do not cool, furnace ductwork can be used for A/C systems.
When the thermostat setting is raised, furnaces reach the new temperature more quickly than boilers.

In favor of boilers:

Furnace ductwork can create a drafty building where dust and dander can spread.
Natural gas furnaces carry the risk of carbon monoxide leaks.
The radiant heat from a boiler is generally more comfortable than furnace-forced air heat.
Boilers are usually less noisy.
In some situations, boiler-heated water can be reused for laundry and showers.
Boilers are usually more efficient and require lower energy expenditure.

Which One is Better for Your Business?

That depends on your requirements, your budget, and the specifics of the models you’re considering. If you’re replacing a system, it’s often easier to use the same type of system you already own. On the other hand, replacement time is the best time to make a change.

If air quality is one of your biggest considerations, you may prefer a boiler. Boilers are often chosen for large buildings because of their ability to evenly heat large spaces and many rooms.

If you are replacing an older system, a new model of either one is likely to be more energy-efficient than what you currently have.

If you’d like to discuss the pros and cons of your specific situation, 1 Source Mechanical can help you arrive at the best decision .

How to Tell if You Have a Boiler or Furnace

Some of the visible differences:

A boiler has round pipes, usually copper or iron, while a furnace has large and boxy ductwork.
Furnaces often extend to the ceiling, while boilers tend to be shorter.
A building with boilers has radiators or radiant floor heating, while furnaces use vents and registers.
An internet search on the brand name and model number will tell you which it is.

A Complete Guide to Commercial Refrigeration

Thu, 05 Sep 2024 15:53:46 GMT

Written by: 1 Source Mechanical

Businesses such as restaurants, country clubs, hospitals, and grocery stores wouldn’t be able to function without commercial refrigeration. All these organizations have a vital interest in keeping foods and other goods cool and safe. Each industry has its own refrigeration requirements, and 1 Source Mechanical has the expertise to support all of them with this critical need.

What is Commercial Refrigeration?

Commercial refrigeration is keeping things cool or cold on a commercial scale. It includes refrigerators, coolers, and freezers, but it’s far more sophisticated than residential refrigeration and freezing. Commercial units must be designed to withstand the challenging environments found in buildings as diverse as convenience stores and food processing plants.

Commercial refrigeration must maintain a consistent cool or cold temperature that ensures that food and other products stay safe and fresh and are not compromised by bacterial growth. Some examples of these refrigeration units are walk-in coolers, reaching-in refrigerators and freezers, and display cases. Each commercial unit is specifically designed for the function it must perform.

How Do Commercial Refrigeration Systems Work?

The systems are composed of components that support a cycle whereby a refrigerant absorbs and expels heat to cool the unit’s interior:

The compressor is the heart of the system. It initiates the cycle by compressing the refrigerant to increase its temperature and pressure.
The condenser cools the heated refrigerant and converts it from a gas to a liquid.
The evaporator enables the refrigerant to absorb heat from the unit’s interior and cool that interior.
The expansion valve controls refrigerant flow into the evaporator to allow effective heat absorption.
The refrigerant itself circulates through the system, absorbing and releasing heat.
The thermostat senses the inside temperature and signals the compressor to activate or deactivate.

How to Choose a Commercial Refrigeration System

Different businesses and industries need different types of systems. Each usage has its own requirements for size, capacity, energy efficiency, temperature range, and durability. There can also be varying installation and maintenance considerations.

Choose by Type

There are several commonly used types of commercial refrigeration units:

Walks-ins can be coolers or freezers and are used by grocery stores, restaurants, and other food service businesses.
Reach-ins can be refrigerators or coolers. They are smaller than walk-ins and provide easier access.
Display cases are designed to show products to customers while keeping them properly cooled.
Blast chillers and freezers rapidly chill or freeze food, preserving the taste and texture while fighting bacterial growth.
Under-counter refrigerators and freezers are designed to be easily accessible space-saving solutions for locations such as bars and food trucks.

Choose by Industry

The type of industry or business dictates what sort of refrigeration units will be needed. For example:

High-volume restaurants and grocery stores need walk-in units to handle large volumes of food.
Grocery stores also need display units for customer appeal and easy access, as do convenience stores, delis, and even florists.
Restaurants and smaller food service establishments need the convenience of reach-in units.
Businesses with limited space may require under-counter solutions.
Commercial kitchens and manufacturers may require blast chillers.
Restaurants may also need refrigerated prep tables and wine coolers.
Ice cream shops may have both reach-in and display freezers.

Specific industries have specialized requirements, so commercial refrigeration comes in a variety of sizes and configurations.

Commercial Refrigeration Maintenance Tips

Commercial refrigeration units need regular maintenance to keep them operating efficiently and maximize their longevity. Some routine tasks can be done by the owner, but regular maintenance service from a professional is also recommended.

Some tips for keeping a unit in tip-top shape:

Clean the interior every week or two. Remove the food, store it elsewhere, and use soap and water or a refrigerator cleaner.
Clean the exterior to prevent corrosion.
Clean the condenser coils regularly with an air compressor, a small brush, a coil comb, and a coil cleaner.
Clean the evaporator coil with an evaporator comb and a coil cleaner.
Replace air filters regularly.
Clean drain pans and tubes.
Inspect door gaskets.
Remove any water buildup and keep the unit dry.

A routine maintenance agreement with an HVAC expert will reassure you that these tasks are done in a timely manner.

When to Schedule Repair or Replacement Service

The need for maintenance and repair depends on the type of commercial refrigeration and the business facility. Older units may need more frequent service than newer ones. Large facilities where the units are stressed more hours per day may need more frequent attention. Six months is a typical period between service calls, but that’s highly variable. If you see signs of a problem, such as food not staying as cool as it should, don’t wait to call.

Major repair is generally not recommended for units over 10 years old. It will usually be more cost-effective to replace the machine. Refrigeration technology is constantly improving, and you can save on energy bills and also reduce future repair costs.

Here are some telltale signs that you may need to repair or replace your refrigeration:

Food not staying cool or cold.
Sudden appearance of frost.
Water puddling near the unit.
Unexplained noises.
An increase in utility bills.

Signs Your Commercial Building has Poor Air Quality

Thu, 15 Aug 2024 13:22:01 GMT

Written by: 1 Source Mechanical

Poor air quality in a commercial building is more than merely unpleasant. It can affect the health and productivity of your employees. It can be a sign of issues that will diminish the value of your property. If you think you might have air quality issues, contact an HVAC repair and maintenance specialist such as 1 Source Mechanical for commercial air quality testing.

Most Common Air Quality Issues

Several air quality issues negatively affect a commercial building, its workers, and its visitors. Here are some of the most common.

Dust Buildup

If air quality is poor, dust and other particulates can build up on surfaces. These might be outside pollutants such as vehicle exhaust or airborne dirt or soot. They also might come from indoor sources such as cleaning compounds, manufacturing chemicals, and construction materials. They can cause respiratory problems and make the facility into a place no one wants to be.

Unpleasant Odors

Obnoxious odors are a problem in and of themselves and also a symptom that larger issues might be lurking in the background. The cause could be trash and garbage not being properly disposed of. It could volatile organic compounds (VOCs) to cycle through the facility, and it could even be the result of mold or mildew.

Improper Ventilation

You can’t have safe, clean air in your building without proper ventilation. Without good movement of warmed and cooled air , the facility might feel stale and stuffy, either in a few rooms or throughout the physical plant. Poor ventilation can lead to excess humidity, which creates a breeding ground for mold, mildew, and other pathogens.

Mold & Mildew

Mold and mildew create perhaps the most serious air quality issue you can be faced with. Mold needs moisture to grow, so you have to do more than just get rid of the mold. You must also identify and remediate the source of moisture that gave it a foothold. Mold is a serious health threat to anyone who spends time in the building .

Allergens

Common allergens include dust mites, pollen, and spores. They can come from inside the building or from outdoors. These can play havoc with people who have allergies and/or asthma. The good news is that purification systems will remove almost all of these.

5 Signs of Poor Indoor Air Quality

Sometimes the signs of poor air quality are apparent inside the building itself. These symptoms include excessive humidity, dust buildup, unexplained odors, and inconsistent temperature from room to room. One of the most dramatic ways bad air quality exposes itself, however, is in the health of the workplace’s occupants. If you observe employees taking more sick days, lagging in productivity, and appearing fatigued, air quality may be unhealthy or even dangerous .

Here are five problems you might notice.

1. Coughing or Trouble Breathing

If more people than usual are coughing, rasping, or appearing to have trouble breathing, there may be airborne irritants such as dust and pollen. Breathing problems are a distraction and make it hard for employees to concentrate on their work.

2. Allergic Reactions

Telltale signs of allergic reactions include sneezing, coughing, and watering eyes. In some cases these are hard to control, People who have asthma or who are susceptible to allergies may look more uncomfortable than usual or report that their symptoms have worsened.

3. Dry Skin

Many people have dry skin as a seasonal problem, but dry skin caused by pollutants might show up at any time of year. It could be accompanied by dry eyes and eye irritation. It’s possible that an imbalance in humidity from area to area could be at fault.

4. Headaches

It’s not uncommon for people to complain of headaches when there are pollutants, particularly VOCs, in the indoor air. That’s because these irritants can cause the sinuses to inflame, increasing pressure in the head. Sometimes these headaches are accompanied by dizziness and fatigue. People who are subject to migraines are especially at risk.

5. Nausea

Some studies suggest an association between low-quality air and gastrointestinal diseases due to an altered intestinal microbiome. Nausea can be a sign that unhealthy air is moving someone in this direction.

How to Prevent Air Quality Issues

To prevent air quality issues, it’s best to eliminate the causes before they can have an impact. Routine steps like properly disposing of garbage, keeping vents open, changing filters, and using cleaning chemicals according to instructions all help. You should also watch for signs like dust buildup, odors, and excessive humidity.

Sometimes, however, circumstances that might turn into air quality issues are difficult to detect. Routine inspection and maintenance by a professional commercial HVAC contractor is the best way to stop air quality issues before they start. The top HVAC companies have the latest equipment to take advantage of the most recent innovations in commercial HVAC. They can do the necessary cleaning and perform minor repairs before small problems turn into big ones. These businesses can perform services such as balancing to ensure consistent airflow and temperature throughout your facility.

When to Test & Balance Your Commercial HVAC System

Tue, 30 Jul 2024 21:20:54 GMT

Written by: 1 Source Mechanical

HVAC balancing is the process of achieving the correct air and water flow throughout a commercial building. Why does your HVAC system need to be balanced? Balancing allows the ducts to deliver the right amount of air to each room in the building. It ensures that fresh air is continually being delivered. It prevents hot or cold spots and maintains a comfortable temperature throughout the facility.

Balancing is accomplished by adjusting factors such as temperature settings, dampers, valves, and fan speeds. The process consists of three steps sometimes called TAB: testing, adjusting, and balancing .

Testing assesses the HVAC by measuring characteristics such as temperature, pressure, air movement, and air and water quality.
Adjustment sets devices to optimize efficiency.
Balancing involves coordinating all the components of the HVAC system, from thermostats to dampers, to work harmoniously.

When an HVAC system is in balance, the ducts and dampers properly direct and distribute airflow. The temperature is comfortable and the air is fresh in every part of the building.

How Often Should You Test & Balance Your Commercial HVAC System?

An HVAC system must be balanced when it’s installed. Sometimes, that’s enough for the life of that system. On the other hand, many professionals recommend testing, and balancing if necessary, every two to three years.

When there are major changes to the building or the HVAC system itself, the HVAC should be rebalanced. Also, equipment wear and changes in room configuration can throw off the balancing.

There are several signs that your system may require balancing. If you check the temperature on cold or hot days, and it’s inconsistent from room to room, it may be time to test and balance HVAC. Other indicators include stuffy air, excessive humidity, drafts, foggy windows, and doors closing without any obvious reason. If you experience these symptoms, check with a professional for an assessment.

Benefits of HVAC Testing & Balancing

A properly balanced HVAC system results in a reliable year-round temperature in every room, regardless of the season. The airflow will be consistently at the right level. There will be no more sweltering in summer, shivering during the winter, or putting up with uncomfortable, disruptive drafts. Here are some of the specific benefits of a balanced HVAC.

Improve Air Quality

The air in a building with balanced HVAC isn’t merely more comfortable. It’s also healthier for your employees and for anyone else who visits the facility. When humidity is at the proper level, contaminants such as mold, pollen, and dust find it harder to get a foothold. People with issues like asthma and allergies are less likely to be affected. For your employees, that adds up to greater productivity and less time away from the job.

Extends Your System's Lifespan

Your HVAC is a huge capital investment. Anything you can do to make it last as long as possible is worthwhile. When your system is working extra hard to compensate for improper balancing, it undergoes unnecessary additional stress.

HVAC maintenance is an expenditure that repays you over the long run by delaying the significant expenditure of replacing your system. With regular maintenance, a professional can often recognize small issues and address them before they become big ones. They can minimize wear and tear on your assets. Maintaining the balance is one of the most important factors in effective HVAC maintenance.

Save on Energy Costs

Rising energy costs are a major concern for every business today, and that goes double for those that maintain a commercial building. Fluctuating and inconsistent temperatures cause your HVAC to cycle more than it has to. It often results in occupants cranking up the heat or the air conditioning to achieve a tolerable indoor temperature. The better your HVAC system balance, the less likely the building is to experience spikes in energy usage and unnecessarily high utility costs.

Also, a more balanced HVAC is a greener HVAC. Your customers expect today’s companies to conduct business and operate physical structures with concern for the environment, and HVAC balancing helps you do just that.

Don't Overlook Ductwork

The ducts are a critical component of your HVAC system. Cooled or heated air doesn’t go anywhere without them. Ductwork is subject to a variety of problems, including leakage, blockage, and improperly sealed connections. There can be ducts that are not correctly sized for the job they are called on to do. If ducts are not in good working order, test results will be unreliable, and balancing adjustments cannot do what they are intended to.

For effective HVAC balancing, the first step is a review, analysis, and inspection of the building’s ductwork system. An HVAC professional can uncover any issues that need to be addressed and then effect the necessary repairs. Once that is done, they can turn on the system and proceed with testing, adjustment, and balancing. They can be confident that their test results are meaningful and that their adjustments and balancing will get the job done.

How Do HVAC Systems in High Rise Buildings Work?

Wed, 06 Mar 2024 21:11:15 GMT

Written by: 1 Source Mechanical

High rises, whether they are residential, commercial, or mixed used, require specialized HVAC systems. These structures present challenges that standard HVAC systems are not equipped to handle. There are issues around temperature control, air circulation , and humidity management, and it takes a different type of HVAC to control the internal climate and ensure air quality.

Conditions are different on different floors of a high rise. There are temperature and humidity microclimates in different parts of the structure. Outside temperature is generally lower near the top of the building. Air pressure varies from the upper stories to the lower ones. Air circulation presents unique challenges in a tall building. These factors require an HVAC system in high rise building that is specifically designed for the job.

Components of HVAC Systems in High-Rise Buildings

High rise HVACs are complex. There are a number of components , and each relies on and interacts with the others. There are the standard components that are present in all HVAC systems, and there are special components and technological innovations that support the stricter requirements of a high rise HVAC.

Heating systems include the boilers and heat pumps responsible for the distribution of warm air and hot water throughout the system.
Air conditioning chiller systems and refrigerant flow systems provide cooling for all the floors.
Ventilation systems include filters and sensors and facilitate the exchange of internal and external air.
Advance control systems are especially important in high rise HVACs because of the sophisticated real-time integration that is required for heating, air conditioning and ventilation systems to work together.
Zoning systems split the building into zones and allow precise climate control in specific sections of the building. At any given time, the heating or air conditioning operates only where it is needed. Unnecessary heating or cooling of infrequently occupied areas is avoided.
Smart thermostats allow for remote monitoring and control of temperatures, varying them as needed through the structure.
Variable refrigerant flow (VRF) systems control the amount of refrigerant flowing to and controlling the temperature in various zones.
Air purification devices include filters and other purification systems to remove pollutants and pathogens.
Energy recovery ventilators capture waste energy from exhaust and pre-condition incoming fresh air.

Types of High-Rise HVAC Systems

Several types of systems have commonly been used in high rise HVAC.

Packaged units have been the traditional high rise HVAC system. An advantage is that they can be installed in an existing wall opening. They tend to be noisy and provide less comfort than more modern systems.
The central water-cooled system uses a central cooling tower and a boiler. There are water-sourced heat pumps in each of the units. This works well to provide ventilation and comfort, but the extensive piping system can be at risk for leaks.
Individual split systems consists of separate units for each room on each floor. They are relatively inexpensive to install, but they can take up a lot of space in each unit.
Four pipe water systems have pipes for boilers and air-cooled chillers. They provide both hot and cool air using fan coils in each unit. While these systems are energy efficient, they are also expensive to install.
Variable refrigerant flow (VRF) systems provide customized heat and cooling to each unit in the building. The efficiency and comfort make it a popular choice today.

With new high rise buildings, it’s becoming common practice for architects and engineers to design the HVAC system as part of the overall design of the structure. This leads to HVAC that works as effectively and efficiently as it possibly can because it’s optimized for a specific high rise.

Benefits of HVAC Systems in a High-Rise Building

High-rise HVAC systems get more sophisticated with each new building. With better understand of energy-efficient design, even more capable advanced control systems, and the increased use of zoning, comfort and cost-effective operation are at an all-time high.

High rise HVAC is not merely about climate control. These HVAC systems also address productivity, occupant well-being, operational costs and environmental impact.

These are just a few of the benefits :

Human comfort. A suitable temperature and humidity is critical for residents and office workers. A comfortable building is a building where floor space will be in demand.
Improved air quality. Effective ventilation and filtration systems keep pollutants and pathogens out of the environment, ensuring a healthy building for everyone who lives or works there. Risk of respiratory issues is greatly reduced.
Increased productivity. Office workers who spend their days in a building controlled by good high rise HVAC work more effectively and productively. Studies have demonstrated the effects of comfortable indoor conditions on satisfaction and productiveness.
Lowered operating costs. With zoning and advanced controls, it’s possible to direct heat and cooling only where it’s needed. The U.S. Department of Energy states that efficient HVAC systems can reduce energy bills by as much as 30 percent.
Lower environmental impact. Lower energy usage is good not only for the building owner but for the planet as well. Buildings with efficient HVAC reduce their carbon footprint and promote environmental sustainability.

Maintaining and Monitoring HVAC Systems

High HVAC systems are complex, and they need to be managed and maintained. You won’t enjoy the maximum benefits and longevity unless you keep them running at their peak efficiency . That means preventative maintenance, regularly scheduled inspections, and timely repair of small problems before they can become big ones. It includes ongoing monitoring and predictive maintenance based on building trends. It takes an HVAC company with expertise and experience.

What is an HVAC Cooling Tower?

Fri, 23 Feb 2024 21:18:46 GMT

Written by: 1 Source Mechanical

Cooling towers are common sights on the rooftops of commercial buildings. They’re designed to get rid of excess heat from water that circulates throughout the building. This water needs to be kept cool for air conditioning or to control the temperature of any industrial equipment used inside.

An HVAC cooler tower is a heat exchanger. It uses water and air to transfer heat from air conditioning and other internal systems to the outdoor environment. Water and air are brought into contact causing some of the water to evaporate. This lowers the temperature of the water that is circulated through the tower and returned into the building.

The cooling tower is an important part of a commercial HVAC system, and its care is as vital as other tasks such as maintaining proper ventilation or balancing an HVAC system .

Types of Cooling Towers

There are a number of ways of classifying cooling towers. For example, there are open and closed towers. Sometimes these are called direct and indirect towers. Open towers expose the water directly to the atmosphere. The warm water is sprayed over a fill to maximize the contact area, and air passes through the fill and removes heat via evaporation. In closed towers, the building’s water does not come into contact with outside air but instead is cooled within tubes. Other water, water that circulates only within the tower, is sprayed over the tubes, and then a fan blows air across them, cooling the water within the tubes.

Towers may also be differentiated by the direction of the airflow, i.e., whether the air flows across or counter to the water. Crossflow cooling towers are those in which the air flows horizontally, across the vertical direction of the falling hot water. In a counterflow system, the air flows upward against the falling water. In cold climates, the fans and motors of crossflow systems may need to be protected to prevent them from icing up.

Towers are also classified by whether the draft is natural or mechanical. In natural draft towers, the heated air is released directly into the atmosphere. These are typically used in power plants and other large industrial sites. With mechanical draft, the air is forced through the structure by a fan. This is more effective than the natural draft arrangement, but it comes at the cost of additional energy consumption.

In addition, there are induced draft and forced draft towers. Induced draft towers have fans on the top that pull air up through the water and fill. With forced draft towers, air is pushed up by blowers and the base on the unit. Induced draft towers are significantly more efficient, and forced draft towers find limited use.

Towers are sometimes classified by whether they are factory assembled (FAP) or field erected (FEP). With FAP, a small tower might come from the factory as one unit, but a larger one will be delivered in several pieces to be assembled on-site.

Components of a Cooling Tower

An HVAC system has major components , and the cooling tower has significant components as well.

The tower itself. It’s the largest and most visible component. It may be made of wood, concrete, steel, or fiberglass. With proper construction and maintenance, the tower will enjoy a long life cycle.

The water distribution piping. It carries the hot water to the top of the tower and delivers it throughout the tower’s distribution system .

The heat transfer medium, commonly called the fill. This is the area where water meets air so heat transfer can take place. It often consists of packs of thin corrugated plastic sheets or sometimes as a grid pattern of splash bars. It exists to maintain thermal efficiency and make the heat transfer as effective as possible.

Drift eliminator. During heat transfer, droplets of water can escape from the cooling tower as carry-over or drift. There’s a risk that these droplets could fall on surfaces where they’re not wanted or even on people. Drift eliminators remove the carry-over droplets.

Fan deck. The working surface of a tower affords access to the tower mechanicals and the fill for inspection and maintenance.

Cooling tower fans. These promote the circulation of air where it’s needed in the cooling tower.

Cold water basin. This is the collection point for the water with heat removed. From there it can be distributed through the building.

What is the Purpose of a Cooling Tower?

An HVAC cooling tower exists to reduce the temperature of the water that circulates throughout a building. Air conditioning equipment and other industrial equipment generate heat, and often this heat is in the form of heated water. This water needs to be cooled so that it can continue to travel through the building and carry away more heat. The cooling tower is a heat exchanger that exposes the hot water to air, evaporating some of the water and bringing down the temperature of the water.

From a broader perspective, the purpose of a cooling tower is to keep a commercial building comfortable and to keep industrial equipment from overheating. This is especially important in power plants, steel mills, chemical processing plants, and manufacturing facilities that operate heavy machinery. However, water towers are also important for airports, shopping malls, schools, hospitals and hotels. No one wants to spend time in a building where air conditioning is needed but doesn’t work properly.

Fortunately, the technology of cooling towers is constantly improving. These innovations afford ever-increasing levels of comfort and safety.

As you can see, there are many decisions to make when choosing a cooling tower. To fulfill its purpose, an HVAC cooling tower must be properly selected, installed, and maintained. It may be out of sight up on the rooftop , but it should never be out of mind. 1 Source Mechanical is the HVAC installation and maintenance leader in the Chicagoland area.

4 Benefits to Automated HVAC Building Control

Fri, 02 Feb 2024 14:58:42 GMT

Written by: 1 Source Mechanical

What is Automated HVAC Building Control?

Automated HVAC building controls are devices that manage a heating and cooling system. They can be as simple as a smart thermostat or as complex as building automated systems (BAS) that control security, lighting, and other systems in addition to HVAC.

They typically consist of a controlling device connected to the building’s infrastructure. Factors such as temperature, humidity, and airflow can be monitored and adjusted in various zones of a building. Systems can be set up to make many of the adjustments automatically. BAS can be manually controlled at a central location and in many cases also controlled from a smartphone.

What are the Benefits?

There are a number of reasons to deploy HVAC automation controls.

Enhanced System Efficiency

Companies that deploy automated HVAC controls almost invariably see a reduction in monthly energy costs. Timers and sensors throughout the building collect information and feed it into the system. A properly installed system can increase or decrease hot or cool air to sections of the building that need more or less of it. The overall building temperature is maintained with less energy expenditure. Also, information recorded by the system can be used to analyze and make ongoing energy-saving adjustments.

Improved Air Quality

A BAS can dynamically adapt to changes in air quality the same way it does to changes in temperature. The HVAC filtering systems can remove indoor pollutants such as dust, pollen, bacteria, and chemical mist. The system can alert a building manager when there is an air quality issue anywhere in the building. It will also enhance air quality by managing air distribution .

Long-Term Cost Effectiveness

Automated HVAC savings are not merely a matter of reduction in utility bills. The long-term savings can justify HVAC installation costs . BAS owners should expect a reduction in ongoing repair and maintenance expenses. That’s because the system detects problems early, before they become big ones, and it solves many problems on its own without the need to bring in repair technicians.

With a BAS, there’s less need for a team of technicians to spend costly hours diagnosing and resolving problems. The system detects and often resolves issues that could cause expensive repairs if they went unrecognized. Often a BAS, even one in a complex building, can be managed by an operator and a single technician.

Increased Comfort & Boosted Employee Productivity

It’s no secret that employee comfort affects productivity. A building that’s too hot, too cold, too stuffy, or has low-quality air makes people think about how they feel rather than the work. An automated HVAC keeps the temperature and humidity constant, the airflow adequate, and filters out pollutants. Who wouldn’t work better in those conditions?

With all the benefits, expect to see more automated HVAC controls installed in new buildings and retrofitted into existing ones. If you’d like the advantages of a BAS for your building, contact 1 Source Mechanical. We’re the Chicagoland leader in HVAC installation and maintenance.

How do Radiant Tube Heaters Work?

Fri, 15 Sep 2023 15:15:21 GMT

When you're exploring options for a commercial HVAC system, you may come across radiant tube heating systems. This type of heater offers a quiet, draft-free way to warm a commercial or industrial space.

However, many people have questions about how radiant tube heaters work. Read on to learn about the types and benefits of radiant heating, so you can make an informed choice of heating systems for your commercial space .

What is a Radiant Tube Heater and How Does it Work?

What, exactly, is a radiant tube heater? This type of heater, sometimes known as infrared, works by moving waves of heat through the air. It works much like the sun's rays, which emanate from above and heat the surface of the earth.

Heat from the sun takes the form of electromagnetic waves that travel until they reach a surface or an object. When the rays strike, that radiant energy is absorbed and converted to heat, that's then reflected back outward.

Radiant tube heaters work much the same way. A radiant tube heater is usually installed near the ceiling. This type of heater starts with combustion, thanks to an electrode that ignites air and gas inside a sealed tube.

The flames create radiant energy that's directed downward. The energy waves travel until they hit a surface — such as a floor — or an object, like furniture or machinery. The surfaces and floors absorb the radiant energy, creating what's known as a "heat sink."

This heat is then reflected back into the space, creating a warm, comfortable temperature that's free from drafts. Because the heat sink is concentrated at the floor level — i.e. where people work and live — this creates a comfortable environment .

Benefits of Using Radiant Tube Heaters

Now that you understand how radiant tube heaters work, your next question probably concerns the benefits of this type of heating system. In fact, radiant heat offers a number of benefits for commercial property owners.

First, radiant tube heaters are more efficient . They use gas and a small amount of electricity to create heat. This makes them more efficient than most forced-air systems.

In addition, with radiant heating, floors and objects absorb and reflect heat back into the space. This cycle of radiation, absorption and convection leads to faster heat recovery, and means you can set the thermostat at a lower temperature.

Radiant tube heaters can be positioned strategically and only heat the areas you want to heat. For instance, when used in spaces with high ceilings — say, for instance, a warehouse or hangar — the downward direction of the infrared waves means the large, empty spaces above aren't heated, reducing energy waste. Instead, warmth is focused at the floor level.

They also tend to cost less to operate than electric-based heating systems. Radiant tube heating operates in a similar manner to electrical resistance heating, in which electricity heats wires so that they emit heat waves. However, radiant tube heating uses much less electricity, leading to significant savings on electric bills .

Another benefit lies in the comfort levels this type of heating system produces. Radiant tube heaters warm up a commercial space in the same way that the sun warms the earth.

It's a gentle, enveloping warmth that feels even and comfortable to those who work and live in the space. Some describe the heat created by radiant tube heaters as comparable to the feeling of warmth one gets when standing near a fireplace.

Plus, radiant tube heaters don't require ducts . This creates a number of benefits. First, radiant tube heating systems are quieter than forced air systems. With radiant heating, no one has to listen to the constant noise of fans cycling on and off as air whooshes through the ductwork.

Lack of ducts also means lack of drafts. With the even warmth created by radiant heating, employees, customers and residents won't experience cold or hot spots within the building.

Less air blowing around means fewer allergens, as well. This can reduce dust and result in healthier indoor air quality .

Finally, radiant tube heaters tend to require less maintenance. They're easy to install, can be used indoors or outdoors, and with proper maintenance , last for many years.

What are Radiant Tube Heaters Used For?

Radiant tube heaters are an ideal choice for commercial and industrial spaces with high ceilings. When used in high bay spaces like warehouses, airplane hangars and stadiums where forced air systems are inefficient, property owners can save money .

Spaces with high ceilings don't often benefit from the use of forced air heaters. Because warm air rises, the floor area — where employees, customers and residents are — tends to be colder and less comfortable. Plus, energy spent heating high, empty ceiling spaces is energy wasted.

Radiant tube heaters offer an efficient, effective solution. They allow for the maintenance of a comfortable ambient temperature without excessive heat loss or inefficient energy use.

Radiant Heat vs Other Types

What is the difference between radiant heat and other types of heat? Let's look at three ways that heat transfers :

Conduction takes place when molecules come into contact with others and transfer energy. Imagine conduction like the break in a billiards game, when the cue ball hits another ball and causes them all to move.
Convection takes place when heat waves move through water or air. An example of heat convection is when water boils in a pot.
Radiation is when heat is transferred through electromagnetic waves. If you've ever held your hand over a toaster, you've felt the transfer of heat through radiation. This is how radiant tube heaters work.

What Is An Air Handler?

Mon, 21 Aug 2023 18:30:00 GMT

The world of commercial HVAC systems has a language all its own. Of course, you only need to learn all the specialized lingo if you're an HVAC professional.

But a few terms that pop up frequently, such as air handlers and fan coil units. Read on to learn the definition and differences of a fan coil vs air handler.

What's an Air Handler?

An air handling unit is part of an HVAC system. Also known as an AHU, this component brings fresh air in from the outside . The AHU then cools or heats the air and circulates it through the building's duct system.

Air handlers use various components , such as heating and cooling coils, blowers, and sound attenuators. Some use refrigerant, while others use water to cool the air. But they all work by bringing in outside air, mixing it with indoor air, and chilling or heating the air by passing over a coil. Then the air is filtered and distributed.

What's a Fan Coil Unit?

A fan coil unit, or FCU, is a standalone system. It's not attached to duct work. Rather, it simply cools (or heats) air that's already indoors, then recirculates it.

FCUs work by drawing air over a cooling or heating coil. Then the air is recirculated. Fan coil units are often used to cool or heat smaller areas , such as single rooms.

While both AHUs and FCUs cool or heat air by drawing it across coils, they are not the same. Fan coil vs air handler differences include:

Air handler units are connected to duct work, and draw in air from the outside. Fan coil units use air that's already indoors, and are not connected to ducts.

AHUs can heat or cool entire buildings. FCUs are used to heat or cool smaller areas, such as single rooms.

AHUs are part of a larger HVAC system. FCUs are stand-alone units.

AHUs tend to be quieter and more expensive. FCUs are louder, but less expensive.

How Many Types are There?

When it comes to fan coil vs air handler, there are multiple types from which to choose. Let's start with fan coil units.

Two main types of FCUs have to do with how they handle air. The draw-through FCU pulls air through. The blow-through FCU pushes air. FCUs can be configured to mount on the ceiling, or the floor.

There are also two types of ACUs. Draw-through ACUs utilize fans to pull air from outdoors and draw it through a mixing box, across coils, and through filters. They may be vertical or horizontal.

Blow-through air handlers also use fans, but they push air through the mixing box, across the coils and through filters. Then the air is blown through the ducts.

How Do I Select the Right One?

Choosing the right HVAC unit for your commercial building can seem challenging. In many cases, an AHU is the best choice to heat or cool an entire building. These units work in tandem with the HVAC system and ducts.

For smaller spaces or tight budgets, fan coil units may offer a solution . These simple devices may be used to cover areas where the HVAC doesn't quite reach.

What is a VRF HVAC System and How Does it Work?

Wed, 09 Aug 2023 18:36:01 GMT

If you're seeking an energy-efficient HVAC system that offers a quick return on your investment, look no further than a variable refrigerant flow system. Also known as a VRF system, this relatively new type of HVAC is growing in popularity across the U.S., thanks to its ability to save on energy costs.

But what, exactly, is a VRF system? Read on to learn how variant refrigerant flow technology works, the best ways to implement it, and how this energy-efficient technology can benefit your commercial property.

Understanding VRF HVAC Systems

Let's start with the basics: What is a VRF system? A variable refrigerant flow system is a type of ductless HVAC that's used in both commercial and residential properties of varying sizes.

As evidenced by its name, this type of system uses refrigerant at varying levels in order to cool and heat a space. To do this, a VRF system uses an outdoor compressor unit and distributes treated ("conditioned") air to multiple indoor zones.

However, VRF systems work a bit differently than other HVAC systems. And though they can be used in many different types of spaces, figuring out if a VRF system is a good choice for your commercial property can be confusing. That's where expert HVAC professionals like those at 1 Source Mechanical come in.

If you've never heard of VRF systems before, you're not alone. While this type of HVAC system has been around for decades in other parts of the word, it started growing more popular in the U.S. in the 2000s, especially because the rules and regulations around energy usage tightened.

Variable refrigerant flow technology comes from Japan, where it was developed in the 1980s . Japanese scientists were trying to figure out a better way to cool and heat large buildings, such as factories. Instead of using multiple compressor systems to heat or cool to multiple indoor units, scientists at the Daikin company discovered a way to vary the volume of refrigerant.

This allowed them to use a single compressor unit, saving energy and money. Along with energy savings, the technology offered flexibility to heat and cool different sized spaces. VRF systems quickly became popular in many countries around the world.

In recent years, VRF technology has advanced rapidly, becoming both more efficient and easier to install. This has led to a growth in popularity, especially among property owners seeking commercial HVAC solutions .

Comparing VRF Systems to Traditional HVAC Solutions

What makes a VRF system different from a standard HVAC system? Most HVACs fall into two general categories: split systems with ducts, or mini-split systems without ducts.

In most cases, a split system uses a compressor unit (often outside), an evaporator unit inside, and a series of ducts to distribute treated air throughout the building. Such systems use refrigerant and water to lower air temperature as it passes over a series of coils.

So how is a VRF system different? While a VRF system is ductless, it's not water-based. It uses refrigerant, but not chillers or coils.

Instead, it uses compressors known as inverters. Compression inverters employ responsive technology that responds to outdoor conditions, such as temperature and humidity. This means the unit can run at variable speeds as needed, to save energy.

VRF systems also have multiple air handlers. Lack of ducts means air is distributed through multiple indoor units, usually installed on the ceiling or walls. This allows building occupants to heat or cool based on specific conditions and needs within a room or space.

Benefits of VRF Systems in HVAC Technology

If you're considering HVAC replacement for a new commercial property or a renovation, VRF systems offer a number of benefits. First and foremost, a VRF system provides energy efficiency.

Multiple air handlers mean building occupants can adjust heating and cooling for specific needs within smaller spaces. Refrigerant flow is variable, depending on the specific heating and cooling settings. This decreases energy usage.

The ability to adjust temperature in specific areas doesn't just help lower utility bills. It also increases occupant comfort.

Plus, customizable controls mean specific areas can be both heated and cooled at the same time. This is an important benefit in settings where, for instance, employees work and equipment must be maintained.

VFR systems can be ideal choices for buildings with limited space. They tend to be less bulky, more streamlined, and take up less room than traditional HVAC components . This means VFR can be a good choice for retrofits or renovations.

VFR systems are also easily scalable. This makes sense in both large and smaller spaces. Plus, they're quieter than most traditional HVAC systems, which reduces ambient noise.

Finally, VFR systems are easier to install, thanks to a lack of ducts. Of course, any HVAC equipment requires professional installation. Call the experts at 1 Source Mechanical to learn more about issues related to retrofitting, renovation, and installation .

Applications and Considerations for Implementing VRF Systems in Buildings

What types of buildings can benefit from VFR systems? This technology is a great choice for mixed-use facilities, and other properties that require healing and cooling of a diverse range of spaces.

For instance, an office space may need to be warmer than a retail space. VFR technology allows spaces to maintain a range of temperatures.

They're also a great choice for multi-story buildings. VFR systems make it easier for refrigerants to reach higher floors. When less energy is consumed, utility bills go down.

Finally, VFR systems are a natural choice for hospitality properties. Hotels and resorts need the multi-space capacity that VFR systems offer. Plus, they're quieter and more energy efficient.

How Long Do Commercial HVAC Systems Last?

Wed, 09 Aug 2023 18:05:14 GMT

No matter how well you treat your equipment, all things mechanical have a lifespan. Commercial HVAC systems are no exception to this rule.

You can take steps to extend the lifespan of your HVAC equipment; regular maintenance and qualified repair services can help your system components last longer. (Of course, you can also reduce your system's lifespan by skipping service visits.)

The price difference between repairing or replacing an HVAC can be substantial, which leads many property owners to ask: How long do commercial HVAC systems last? While every situation is unique, some commercial HVACs can last up to 20 years or more. Read on to learn how to keep your HVAC running smoothly and efficiently for the longest possible time.

Factors Affecting the Lifespan of Commercial HVAC Systems

If you're wondering how long commercial HVAC systems last, let's start with the most important variable: maintenance. If you're diligent about following a regular maintenance schedule, an HVAC in a commercial property may run for 20 years or more.

Keep in mind, though, that this is a best case scenario that involves always following best practices, like keeping up with regularly scheduled maintenance and working with a team of HVAC professionals when repairs are needed.

Think of ensuring your commercial HVAC's longevity in terms of a person making efforts to keep fit and healthy. For instance, following practices like exercising and seeing a doctor regularly helps improve human health. Similarly, scheduled maintenance and qualified repairs help improve your HVAC's performance while reducing wear and tear, increasing longevity.

Other factors that affect how long commercial HVAC systems last may include:

Unit size. If an HVAC unit isn't sized properly, wear and tear increases. That's because an undersized unit will have to work too hard to cool and heat a property, so components deteriorate more quickly. And a unit that's oversized will turn off and on more often, decreasing efficiency and wearing out sooner.

External climate. The climate and environment you live in affects your HVAC's lifespan. In a warm climate, the air conditioning components or heat pump will likely work harder and wear out faster. In a cooler climate, the furnace will work harder and wear out faster.

Interior elements. The interior of the building can affect how long a commercial HVAC system lasts, too. For example, an interior that experiences outgassing from carpets, wood, or other new building materials can place stress on an HVAC, as can fumes from cleaning supplies. The chemicals in these pollutants can cause the HVAC's coils to deteriorate at a faster rate.

Installation and component quality. The quality of the HVAC unit you choose affects its longevity. It's easy to see how sub-par components would tend to wear out or break sooner than high-quality equipment. Installation quality is also important. An experienced, qualified HVAC professional will ensure not only that your unit is correctly installed with the right ductwork and other components, but also that your system is the right size and capacity for your building.

Understanding the Average Lifespan Based on Maintenance

Let's take a look at how average HVAC lifespans differ, depending on maintenance levels:

With no maintenance: Expect your commercial HVAC system to last less than 18 years

With minimal maintenance: Expect an HVAC lifespan of about 18 to 20 years

With some maintenance: A commercial HVAC could last for 20 to 25 years

With high maintenance: Your HVAC's lifespan may reach 25 years or more

Remember: These are simply averages, as not all HVAC systems are the same. Different manufacturers use different components of varying quality, so some may simply wear out sooner than others.

External factors, such as climate, temperature and humidity, as well as internal factors such as air pollutants also play a role in HVAC longevity. But overall, regular maintenance can extend your commercial HVAC's lifespan.

How Can You Extend the Lifespan of your Commercial HVAC System?

As a general rule, you can expect the individual components of your HVAC system to last about:

15 years for a heat pump
15 to 20 years for an air conditioner
20 years for a furnace
20 to 35 years for a boiler

While these average lifespans depend on preventative maintenance, it's important to remember that the fitness level of each component affects how the other components function, too. A simple maintenance lapse in one part of the system can cause or worsen other problems.

For instance, one common lapse lies in forgetting to change air dict filters regularly. While it may not seem like a big deal to let it go for a few weeks or months, that dirty air filter puts pressure on other components in the system. This increases wear and tear. Over time, it really adds up... and subtracts life from your HVAC.

Signs your Commercial HVAC System Need to be Replaced

How do you know when it's time for a new system? The following signs may indicate that your commercial HVAc is nearing the end of its lifespan:

Your system is more than 15 years old
The building isn't being heated or cooled consistently
Repairs are getting costly
Your system isn't energy efficient
Energy bills are increasing year over year

Commercial Coil Cleaning: Is it Important?

Wed, 10 May 2023 19:28:58 GMT

When it comes to commercial HVAC systems, the arrival of spring means that the high humidity and rising temperatures of summer are right around the corner.

Getting that spring cleaning done before the need for cooling really kicks in is key. That means scheduling a commercial HVAC coil cleaning service to keep your system running smoothly and efficiently.

Why is coil cleaning so important at this time of year? Because preventative maintenance now, before the system is working hard, means fewer costly repairs — and less downtime — later in the season. Clean coils also mean more efficient operations, which saves you money.

Here's what you need to know about commercial HVAC coil cleaning.

How Often Should HVAC Coils Be Cleaned?

First things first: how often do commercial HVAC coils need cleaning? Under typical environmental conditions, a cleaning every 12 months or so is enough.

However, different conditions mean different cleaning schedules. Environmental pollutants can lead to dirty coils that need more frequent cleaning . Scheduling a cleaning every three or four months might make sense under these circumstances.

For instance, if you live in an area with cottonwood trees or dandelions, fuzz, and pollen can build up quickly in spring. You'll want to schedule cleaning more often. Often, spring and fall cleaning does the trick.

Similarly, unusually high temperatures require your HVAC unit to work harder than normal, so you'll want to schedule more frequent cleanings during these times of intense usage. Certain very dense coils tend to attract more buildup and may need a bit of extra attention as well.

Every coil situation is different, so checking with the HVAC professionals is the best way to set up a cleaning schedule.

How To Determine When Your Coils Are Dirty

How do you know if you need to schedule a commercial HVAC coil cleaning? Of course, setting up regularly scheduled maintenance is the best way to ensure your coils are clean and functioning properly.

But several signs may point to dirty coils. A straightforward way to tell is simply to take a look at the coils. If they look dirty or have debris in them, it's time to schedule a cleaning.

There's also a more scientific way to determine coil cleanliness . This involves determining if the actual air pressure in your building varies from that noted by the design specifications.

For instance, when a condenser coil is dirty, the refrigerant head pressure will measure higher. But when a DX coil is dirty, you may measure low suction pressure and low airflow .

In addition, if you measure a greater air pressure drop than specified in the design, you've likely got a dirty coil. Your commercial HVAC professional will be able to take accurate measurements.

Risk of Not Cleaning Your Commercial HVAC Coils

What happens if you don't clean your coils? If too much dirt and debris builds up, your HVAC system won't be able to function efficiently. It'll work harder to cool and heat your building, resulting in higher energy consumption — and higher energy bills each month.

But don't just take our word for it; research shows just how impactful coil cleaning can be. A study conducted by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers indicates that dirty coils consume from 20 to 50 percent more energy. Over time, this energy consumption adds up to the tune of tens of thousands of dollars in additional energy costs.

Along with decreased efficiency and increased energy use, a unit with dirty coils will also have to work harder to keep your building at comfortable temperature and humidity levels. This increases the wear and tear on the equipment, and increases the probability of necessary and potentially costly, repairs.

Then there's air quality. Dirty coils make it easier for contaminants, such as mold, mildew, pollen, or bacteria, to enter the airflow. This can lead to respiratory issues that harm the health and well-being of those who work and live in your space.

Benefits of Cleaning Your Commercial HVAC Coils

Clean HVAC coils help your unit run more efficiently. Coils free from grime facilitate free airflow, easier heat transfer, and better dehumidification, all while using less energy. And lower energy consumption means lower energy costs, so you'll save money on monthly bills.

More efficient use also extends the life of your HVAC unit. Clean coils keep your HVAC running smoothly and reduce the likelihood of repair. Setting up a regular maintenance plan to keep coils clean can help your equipment last longer.

Clean coils also mean your HVAC system can cool — and heat — to the comfortable levels that you need in your commercial building. Dirty coils impede function, often leaving your space feeling too warm or too humid.

Clean coils mean your system is less likely to experience downtime. A well-maintained system is not as likely to break down. When the temperature and humidity are high, a broken HVAC system can make interior spaces feel intolerable for workers. This affects productivity and your bottom line.

DIY vs Professional Coil Cleaning

Commercial HVAC cleaning is a job best left to professionals. Coils are usually made from thin aluminum; they're easily bent and extremely delicate. It's not hard to damage coils, resulting in a costly repair bill.

Low-pressure washing, in conjunction with specialized chemicals, is usually the cleaning method of choice. Chemicals may be caustic or toxic, so caution is warranted.

Sometimes, high temperatures or steam cleaning is required. This also involves specialized equipment and expertise.

Comparing Different Types of HVAC Chillers

Wed, 26 Apr 2023 13:58:22 GMT

Phew... it's hot outside! If you've ever wished there was a simple way to cool down the interior of your commercial space, chillers may offer a solution.

Chillers are HVAC components that maximize the cooling capacity of your commercial HVAC system . They work by cooling down water, then distributing it around the building. This lowers the ambient air temperature, creating a comfortable environment for employees and customers.

Read on to learn more about chiller technology and the different types of chillers, and see how 1 Source Mechanical can help you determine if a chiller is right to help keep your commercial property cool in the heat.

What Are Chillers

Let's start with the basics: What, exactly, are chillers?

A chiller is a mechanical device that works with your commercial HVAC system to cool indoor air. In broad terms, the chiller transfers internal heat to an external location. Heat comes from a few sources, such as solar energy beating down on the outside of the building. The building's occupants — and the equipment they use — could also raise the air temperature.

An HVAC system cools the air, keeping it at a comfortable temperature. In large commercial spaces, a chiller helps maximize the air conditioning process.

A chiller works by generating cold water (or other liquids, such as a glycol solution) and moving it around the building. This, in turn, cools the air.

Usually, chillers are located on the roof or in a basement. The machine moves excess heat between an evaporator and a condenser. The evaporator chills the water or refrigerant solution . A pump sends the cooled water around the building, gathering heat as it goes.

That excess heat is then released to the outdoors. The heat transfer may be facilitated by cooling towers, which simply release the heat into the outdoor air, or by a fan that blows across coolant coils.

What are the Main Components of a Chiller?

Chillers usually have four main components:

A compressor
A condenser
Thermal expansion valve or metering device
An evaporator

These components work together to change the water or refrigerant solution from a liquid to a gas. At that point, heat is released. Then the gas is returned to a liquid state.

Here's how these chiller components work together to lower air temperature. First, the compressor pumps heated liquid to the condenser. Here, the liquid is pumped to a cooling area. The condenser meters and pressurizes the liquid, so it transforms into gas as it moves into the evaporator.

Here, the gas vaporizes, all the while absorbing heat from the air around the chiller. This lowers the temperature, and the gas turns back into liquid.

Now the heated liquid is pumped back into the condenser. It's pressurized once again, the heat transfers, and the cycle starts once again.

Different Types of HVAC Chillers

There are two general categories of chillers: vapor compression and vapor absorption. The most common type, vapor compression, uses electricity to power a mechanical compressor that drives refrigerant liquid around the system.

Within the vapor compression category are two types of chillers: water-cooled and air-cooled. In contrast, vapor absorption chillers utilize a heat source to drive the refrigerant liquid through the system. Along the way, the liquid cycles through different temperatures and pressures. Within this category are also two types of chillers: absorption and centrifugal.

Air-Cooled

An air-cooled chiller works a bit like a radiator that cools an automobile engine. It works by using a fan to blow air across tubes filled with refrigerant liquid. This carries the heat away.

Often, these types of chillers are used in small or medium-sized commercial properties. Air-cooled chiller systems work best when the temperature remains below 95 degrees F.

They're usually simpler to install and usually cost less than other types of chillers. However, because they usually sit on the roof, air-cooled chillers may not last as long as other options. They're exposed to the elements and may experience damage or blockage from rain, snow, and wind conditions.

Water-Cooled

Water-cooled types of chillers work in much the same way as air-cooled chillers. However, instead of blowing air across tubes of refrigerant, water-cooled chillers transfer heat in a two-step process.

First, the heat is transferred from vapor into water in the condenser. The heated water is pumped to a cooling tower, where the heat is then released into the air. Sometimes a fan is used to help move the heat along.

Water-cooled chillers are often used in commercial spaces where there's an adequate water supply. They're not as sensitive to ambient air temperature as air-cooled types, so they tend to be a more efficient choice in medium- to large-sized commercial buildings.

Water-cooled chillers often reside in a basement. Because they're protected from the elements, water-cooled chillers tend to have a longer lifespan. However, they're more complex and usually have higher installation and maintenance costs.

Absorption

Absorption chillers pump liquid or steam through lines. As the refrigerant boils into vapor, it passes into the condenser. Then it's reliquified through a chemical process and pumped back into an absorber.

There, the liquid is absorbed, then transformed into vapor again. The cycle removes heat from the air. This type of chiller is most effective in large spaces.

Centrifugal

A centrifugal chiller uses energy and centrifugal force to compress the refrigerant liquid. The liquid is pumped in using spinning blades. As the liquid compresses under pressure, the heat is expelled.

While centrifugal chillers are more efficient, they do tend to cost more upfront. They're best for use in large commercial or industrial spaces.

4 Commercial HVAC Trends That Can Help Your Business

Thu, 16 Mar 2023 15:31:56 GMT

Today's world is all about tech. Everywhere you look, new (and not-so-new) technology has changed the way we work, learn, and play. The latest technological trends can often make life more convenient.

Not surprisingly, heating and cooling systems are also affected by technological advances. From fine-tuned control to greater comfort, HVAC tech offers a number of benefits to commercial building owners and property managers.

Here are 4 commercial HVAC trends that can benefit your business.

Eco-Friendly HVAC Systems

Going green has been a trend for many years and the demand for green building continues to grow. HVAC systems are no exception. Thanks to new technologies, eco-friendly HVAC systems are more affordable — and more efficient — than ever.

Why are green options so popular? For one thing, they're more efficient, using less resources to get desired results. That means decreased energy usage and lower monthly bills, which helps your bottom line.

Plus, they're easier on the environment. Commercial air conditioning releases about 1,950 million tons of carbon dioxide annually, which boils down to about 3.94% of total greenhouse gas emissions every year. Plus, they can leak harmful refrigerants.

Fortunately, green alternatives exist. Eco-friendly commercial HVAC systems may draw power from non-fossil fuel sources, such as wind turbines, solar or even geothermal energy. Newer, more efficient models last longer and offer better performance.

Remember: While commercial HVAC trends point to newer, green technology, the HVAC components still need regular maintenance and servicing to run smoothly and efficiently.

Ductless HVAC Systems

When updating a commercial building's HVAC system , a significant cost lies in the installation and replacement of ductwork. And sometimes, older buildings don't even have enough space — or the right type of space — for compatible ducts.

Fortunately, there's a solution: ductless HVAC systems. Ductless cooling and heating systems are compact, so they fit into smaller spaces. That means they can be installed almost anywhere, eliminating the need for costly and intensive duct installation.

Ductless HVAC systems are also a great solution for buildings that have faulty, leaky ducts. While these efficient units do require an up-front investment, in the long term they're more cost effective than redoing ducts and keeping up with constant repair needs, not to mention energy bills.

Smart HVAC Systems

You probably have a smartphone — but what about a smart thermostat? So-called "smart" technology allows HVAC system components to communicate with each other. For instance, a system with occupancy sensors can adjust temperature, humidity and lighting controls based on how many people are using the building at any given time.

Sensors can also "talk" to each other about factors such as outdoor temperature, humidity, sun position and more, then automatically adjust heating and cooling controls. For example, if part of the building is exposed to direct sunlight for part of the day, the system can turn up the A/C in summer and increase heating in winter, or open and close the blinds.

But the best perk of smart HVAC technology might just be that it allows property managers greater control over system functions. No matter where you are, you can adjust the temperature and humidity from anywhere with an internet connection.

Smart HVAC technology also helps improve indoor air quality. From a smartphone, tablet or laptop, you can monitor air quality. Installation of a smart air purifier can help keep air quality high.

In the long run, this leads to decreased energy consumption, lower energy bills, and more comfortable indoor spaces.

FInally, a smart system collects crucial data about your HVAC system's operation. This information is key when it's time to repair or replace your HVAC system or make other important decisions.

Software and Automation

All of these commercial HVAC trends make it simple to integrate helpful software that automates your building's systems. Overall, the automation process saves you money by using less energy.

Smart equipment and sensors "learn" and adapt to changes in temperature, humidity, occupancy and more. This allows the system to plan and choose the most efficient settings.

Another plus? Software that can sense potential equipment failure ahead of time, saving you time and money on repairs.

Software can also improve your building's indoor air quality. In recent years, the importance of healthy IAQ has come into sharp focus, leading to the development of several new technologies. For instance, today's air purification systems employ tools such as UV lights, hydrogen peroxide, and ionization to kill germs and ensure clean air. IAQ systems can also reduce mold, mildew, fungi and other airborne contaminants, making your building safe and healthy for occupants.

Software interfaces are easy to use, so you can get a handle on your property's energy usage. The ability to change settings and control the system from anywhere is another significant benefit. Software can increase energy efficiency, decrease response times, and lower risk of malfunction.

HVAC Carbon Monoxide: Is Your Business at Risk?

Tue, 07 Feb 2023 22:09:59 GMT

As a business owner, you want to ensure that your property, employees, and patrons are safe. But there's one risk that's easy to overlook — because it's (literally) invisible and odorless.

We're talking about carbon monoxide, also known as the "silent killer." This poisonous gas can't be seen or smelled, but it can cause great harm to human health. Any building with a fuel-burning HVAC system is at risk.

Is your commercial property protected from the dangers of HVAC carbon monoxide? Read on to learn how to keep your workspace safe from this deadly risk.

Signs and Symptoms of Carbon Monoxide Expose

There's a reason carbon monoxide is known as the silent killer: you can't smell, taste, hear, or see it. But carbon monoxide can leak and build up in any building that uses fuel for heating. That includes furnaces that run on oil, natural gas, kerosene, propane, wood, or charcoal.

When these materials burn, HVAC carbon monoxide enters the air. If people breathe in too much, they experience adverse health effects. Signs of carbon monoxide exposure include:

Headaches
Nausea
Dizziness
Weakness
Vomiting
Fatigue
Rapid heartbeat
Convulsions
Chest pain

If you suspect carbon monoxide exposure, immediately evacuate all employees into the fresh air. You may also need to call emergency services, such as the fire department or poison control center. Next, call 1 Source Mechanical for an HVAC assessment.

Commercial HVAC Safety Tips to Prevent Carbon Monoxide Leaks

Fortunately, you can take steps to prevent carbon monoxide exposure. Make sure your furnaces, vents, and any other fuel-burning appliances receive regular inspections from an HVAC professional. The experienced team at 1 Source Mechanical will assess and analyze your HVAC system, and perform HVAC repairs or replacements.

Common culprits include blocked vents. Whether from dust and debris, bird nests, rodents, or simply years of build-up, vent blockages can trap carbon monoxide inside. Since the gas has no odor, you may not notice there's a problem until it's too late.

Another common issue? Leaks or failures in the heat exchanger. When it's working properly , the heat exchanger vents gasses created by fuel combustion, removing them from the building through ducts and vents. But when the heat exchanger malfunctions or cracks, the carbon monoxide leaks back in, filling the building over time.

Regular Inspection and Maintenance

HVAC carbon monoxide is an inevitable by-product of fuel consumption; in other words, there's no way to get around its existence. But the good news is that it doesn't have to cause harm.

The best way to avoid carbon monoxide problems lies in regular inspection and maintenance. HVAC professionals at 1 Source Mechanical regularly inspect your HVAC system, making sure that equipment, like your heat exchanger, is working efficiently.

HVAC professionals will also inspect your building's vents and ducts. Clear, clean ducts carry the carbon monoxide away. Secure, functioning vents then release the carbon monoxide to the outdoors, where it safely dissipates.

At least once every year, schedule an inspection of your furnace, vents, chimneys, fireplaces, and any other fuel-burning equipment. Working with a qualified commercial HVAC service is key. You can even set up a regular maintenance schedule with 1 Source Mechanical to stop HVAC carbon monoxide issues before they start and keep your business safe.

Install Carbon Monoxide Detectors Around Your Business

Carbon monoxide detectors add a layer of protection. Because carbon monoxide is a colorless, odorless gas, it's virtually impossible to know if there's been a leak.

Carbon monoxide detectors can alert you to high levels of the poisonous gas in the air. They provide an early warning, so people in the building can get out quickly. Place carbon monoxide detectors all around your building, on every floor.

Test detectors once a month to ensure they're working properly. Keep the alarms clean and free of dust, and replace batteries about every six months. Check your user manual for specifics, but know that you'll likely have to replace your alarms every five to seven years.

Follow Industry Standards and Regulations

According to the Environmental Protection Agency , all carbon monoxide detectors must conform to the Underwriters Laboratory standard 2034 or the International Approval Services standard 6-96. Check the manual of your carbon monoxide detection devices to ensure you're in compliance.

In addition, most states have specific legislation related to carbon monoxide control in commercial properties. Check the National Conference of State Legislatures website to find specific regulations for your region.

Your municipality may also have certain standards. Work with a professional HVAC service to ensure you're within regulations that may apply.

Educate Employees and Have a Plan

Along with carbon monoxide detectors, annual inspections, and a regular maintenance schedule, be sure to educate your employees about the dangers posed by carbon monoxide.

After all, if the carbon monoxide alarm goes off and no one knows what to do, it's not very helpful. Every business should develop a plan that clearly defines procedures to follow in the case of a carbon monoxide leak:

Educate employees about how to recognize the sound of the alarm
Instruct employees to evacuate the building
Designate a safe gathering space
Do a headcount
Specify which emergency services to call (usually the fire department)
Turn off the heating system
Open windows to let in fresh air if possible
Call a professional HVAC service

1 Source Mechanical HVAC Assessment and Configuration

As a business owner, your first priority is keeping your employees and patrons safe — and that includes HVAC carbon monoxide leaks and build-up. Using detectors, following safety standards, having a plan, and scheduling regular HVAC maintenance is key.

What are the Ventilation Requirements for Commercial Buildings?

Tue, 10 Jan 2023 18:07:15 GMT

Millions of people spend their workdays in commercial buildings . With so many hours spent indoors, ensuring good air quality is key. After all, human well-being requires fresh, clean air — and a healthy indoor climate requires proper ventilation.

How do you know if your commercial building meets ventilation requirements? Of course, each property has its own specifications, with building size playing a key role. But several components underlie a safe and comfortable indoor climate, including ventilation rate, control and maintenance of air quality, contaminant removal, and code compliance.

Read on to learn about ventilation requirements for commercial buildings.

Ventilation Rate

Let's start with the basics: Why is it important to meet ventilation requirements for commercial buildings? Effective ventilation brings fresh outdoor air in, while pushing stale indoor air out. This transfer helps reduce common pollutants, such as mold, mildew, dust, pollen, carbon monoxide, and toxins, which may lead to respiratory irritation or illness. Proper ventilation also controls humidity levels and helps keep temperatures at correct levels.

A comfortable indoor climate starts with the ventilation rate. Industry standards and guidelines are set by the American Society of Heating, Refrigerating and Air-Conditioning Engineers or ASHRAE. According to ASHRAE standard s, the recommended fresh air or outdoor ventilation rates are expressed by cubic feet of air per minute per person, or cfm/person. As a general rule, any occupied building should have a fresh air ventilation rate from five to 10 cfm/person .

Keep in mind that these rates may vary by building size. Ventilation rate standards may also differ depending on how spaces within a building are used. For instance, ASHRAE guidelines call for a break room to have a cfm/person of 5, while labs or media rooms should have a cfm/person of 10.

Control and Maintenance of Air Quality

Ventilation requirements for commercial buildings focus on controlling and maintaining levels of air quality. In 1989, ASHRAE set standards to help building owners and managers make sure that their property's air quality was acceptable.

Specifically, ASHRAE standard 62-1989 defines parameters for indoor air quality limits. These standards lay out ventilation rates and air quality measurements that are acceptable when people live and work within a building. These air quality standards are designed to minimize the risk of negative impact on human health.

Controlling and maintaining air quality through commercial ventilation systems is key. The ASHRAE guidelines account for considerations such as:

Building location and ventilation system placement, including the quality of the air taken into the building from outdoors
Building occupancy; is the ventilation system correctly adapted to the number of people working or living in the building
Do materials used in the building contribute pollutants to the indoor air
Air must travel from rooms with higher air quality requirements to rooms with lower air quality standards, and not vice versa
Air recirculation should not introduce pollutants to new areas
Exhaust vents should not be placed near air intakes and introduce pollutants
Air from rooms where polluting activities take place should be removed, not recirculated

Another issue that may not be included in ASHRAE standards — but is still important — is energy efficiency. An energy-efficient HVAC system will reduce your monthly bills, saving money over the long run. You may also consider factors such as noise levels. A ventilation system that produces loud sounds can be distracting for workers, customers, and building residents.

Given the complex nature of air quality control and maintenance, it's easy to see why ventilation is not a do-it-yourself endeavor. When it comes to ventilation requirements for commercial buildings, working with a reliable commercial HVAC company is a must.

Contaminant Removal

One of the most important considerations when it comes to commercial building ventilation requirements lies in safety, especially as it relates to human health. An effective, efficient system will improve indoor air quality by removing pollutants from the air.

These contaminants may be in the form of particles, droplets, or even gasses. They may come from a range of different sources, both outside and inside a building. For instance, exhaust from nearby traffic may bring carbon monoxide, ozone, lead, and benzene into the building. Outdoor landscaping plants and trees can cause high indoor pollen levels. Contaminants may also come from inside the building, such as from chemicals used for cleaning, mold or mildew, pest droppings, and pollutants from paint, furniture, and building materials.

According to the Environmental Protection Agency , there are more than a dozen contaminants commonly found in indoor air. These include:

Smoke from wood fires; contains gasses and particulate matter
Volatile organic compounds (VOCs) found in paint and cleaning supplies
Smoke from cigarettes and other tobacco/vape products
Radon, a naturally occurring gas that's difficult to detect but often gets trapped indoors
Pesticides and insecticides used to control insects and rodents
Formaldehyde, a chemical often found in building materials, glue, resin, insulation, and cosmetics
Carbon monoxide, a hard-to-detect gas that's released whenever fossil fuels are combusted
Biological contaminants, such as mold, mildew, pollen, dust, mites, dander, and bacteria

These pollutants can cause human health issues. When people breathe contaminants in indoor air, they may experience irritation or damage to the lungs and other health issues. Coughing, sneezing, eye irritation, dry throat, fatigue, and loss of concentration are just a few symptoms caused by unclean indoor air.

Over time, poor ventilation can lead to chronic health problems. Keeping indoor air clean through proper ventilation is key to preventing these issues.

Compliance with Codes

Legal ventilation requirements for commercial buildings vary by state or region. Working with a professional commercial HVAC service will help ensure you're in compliance.

As a general rule, standards focus on ensuring that commercial buildings:

Provide a satisfactory indoor climate, including air quality, temperature, humidity levels, drafts, odors, and oxygen content
Air must be free from pollutants that can pose health hazards to building occupants
Ventilation systems must be properly monitored and maintained

Regular HVAC system maintenance will help keep your building within code, so your employees can be safe, healthy, and productive. Working with a reliable HVAC professional like 1 Source Mechanical makes it easy to maintain compliance.

What is the Procedure for Balancing Commercial HVAC Systems?

Thu, 08 Sep 2022 15:02:51 GMT

Is your HVAC system out of balance? If you're like most commercial property owners, you might have a few questions about the balancing process.

You're likely wondering what the commercial HVAC air balancing process entails. You probably want to know why balancing commercial HVAC systems is so important, as well as how often the balancing process should take place.

Read on to find out how, why, and when your commercial HVAC system needs balancing.

What is Commercial HVAC Air Balancing?

Let's start with the basics — why would a commercial HVAC need to be balanced? Most heating, ventilation, and air conditioning systems in commercial properties utilize a series of ducts that run through the building. These ducts direct airflow throughout the structure, using dampers to distribute air from the heating and air conditioning units to the building's rooms.

When the HVAC system is operating correctly, dampers allow the right amount of air into each room. When air is correctly distributed, the temperature is regulated — not too hot or too cold — and the air is fresh — not stuffy — in each room.

In order for the system to work properly, dampers must be adjusted correctly. The amount of air in each room must be measured in a process known as balancing .

When air enters a room, it takes on that room's shape, much like water takes on the shape of the container it's in. And like water, air follows the path of least resistance. Dampers work to create the right amount of resistance and regulate how much air goes where. This is where balancing comes in.

Commercial HVAC Air Balancing Procedure

How does balancing commercial HVAC systems work? The process involves technical knowledge and skill, as well as specialized tools and tech. In other words, balancing a commercial HVAC system is a job for HVAC professionals .

The first step lies in determining that air's path of distribution. This involves review and analysis of the building's ductwork system. If schematics or blueprints of the ducts are readily available, this is a great place to start.

But often, these documents aren't readily available. Technicians must identify the components of the HVAC system, calculate air output, determine total airflow, and divide the total by the number of rooms in the buildings. Of course, a number of variables affect these calculations, such as:

Room size
Fan static pressure rating
Blower horsepower
Air changes

Once these factors are calculated, technicians essentially "reverse engineer" the HVAC system. They create a predictive model, which will allow them to compare real-life tests of air delivery and return.

Next, the HVAC system receives a thorough inspection. This uncovers any issues that need repair — such as loosened dampers, disconnects, or loss of suspension — that may affect system performance. Once repairs are done, technicians can turn on the system and measure temperature and pressure at various points.

A "balancing hood" tool allows technicians to read airflow at the registers, so they can see how much air is entering a space. Returning air is also measured. This gives technicians the total amount of air, so they can compare reality to the predictive model.

If airflow is higher or lower than it should be, the technician can then adjust fans and dampers to correct the discrepancy. For instance, a damper in a room receiving too much airflow can be closed. This also increases air pressure in rooms that are registered on the lower side.

Technicians continue making adjustments until supply and return measurements fall within 10 percent of specifications. Now the system is considered balanced.

How Does an HVAC System Become Unbalanced?

An HVAC system needs to be balanced when it's installed. Sometimes, that initial balancing is enough, and the system doesn't need rebalancing.

But over time, parts wear down and components shift. The composition of rooms can change, as well. Any of these factors may cause an HVAC system to slide out of balance.

For instance, if dampers and ducts shift or move, airflow lessens or increases. This uneven airflow throws the system out of balance, causing some rooms to feel too hot or too cold.

Changing room setups can affect balance, too. Introducing large pieces of furniture into a room reduces the amount of air volume that's necessary to heat or cool the space. Similarly, computers and other electronic equipment can raise a room's temperature, so less heating is required.

Doors and windows matter, as well. For example, an entryway that's used frequently (or a window that's left open) can lead to a loss of conditioned air.

How Often Should a System be Balanced?

When it comes to balancing commercial HVAC systems, property owners can take comfort in knowing that it's often a once-in-a-lifetime occurrence. All systems must be balanced when they're installed. For some systems, that's enough — consider it a "once and done" process.

But equipment wear and room setup changes may unbalance the system. And an unbalanced HVAC means your system uses more energy, reducing efficiency and increasing costs.

Though some buildings only require balancing when the system is first installed, others may need more frequent balancing. It's easy to tell when balancing is needed.

Simply check room temperatures on hot or cold days. If some rooms are too cool or too warm, an HVAC system balancing may be in order.

5 Tips for HVAC Energy Efficiency

Tue, 02 Aug 2022 19:52:46 GMT

With energy costs on the rise, you may be seeking ways to lower your bills. Start with a look at your HVAC unit.

While newer HVAC systems tend to be energy efficient, many older models aren't. However, there are steps you can take to make your unit run more efficiently and effectively — and save on those monthly utility bills.

What Makes HVAC Units Energy Efficient?

The HVAC unit in your Illinois commercial property has a significant impact on your energy bills. In fact, according to the U.S Department of Energy , the most efficient air conditioning systems consume from 30 to 50 percent less energy to cool the same amount of airspace than less-efficient units.

Newer units often contain technology and features that significantly increase energy efficiency. Even units that are just a decade old tend to use from 20 to 40 percent more energy. If your system is getting up there in age, you may want to consider replacing it with a more efficient HVAC unit .

But what, exactly, makes some units more energy efficient than others? A few variables make a big difference.

More efficient units use a two-stage process for heating. This means that the unit uses the lowest amount of energy to keep the building at a comfortable level. When temperatures drop, a higher level of power kicks in. This helps keep energy consumption down and reduces waste. In contrast, older units without two-stage heating simply run at the same (higher) power level.

Energy efficient HVAC units also use variable speed blowers. It's a similar feature to two-stage heating, in that the blower adjusts speed to external conditions. When more power is needed, the system amps up. When high speed is unnecessary to maintain comfortable temperatures, the power consumption tamps down.

Filter check mechanisms improve efficiency. These features tell you when a filter is dirty or clogged, simplifying the maintenance process. They also reduce wear and tear while preventing overwork, which uses less fuel and keeps the unit running efficiently.

Many energy-efficient units use heat exchangers. This technology prevents energy waste by capturing escaped gasses and reusing them. Less efficient systems vent these gasses, letting them go to waste.

Newer HVAC systems often use sealed combustion chambers. This energy-saving feature takes in air from the outdoors, rather than reusing indoor air that's already been conditioned (why pay to condition air multiple times?). Bonus: Not only is sealed combustion more efficient, it also tends to be safer, as well.

Other energy efficient features include electronic ignition. While older HVAC models usually have gas powered pilot lights that are always ignited, more efficient units use electronic ignition systems. These ignite the pilot flame only when the unit is in use.

How do you know a unit's efficiency? On air conditioning units, take a look at SEER (Seasonal Energy Efficiency Ratio). On furnaces, look at the AFUE (Annual Fuel Utilization Efficiency) rating. Higher SEER and AFUE ratings indicate less energy waste, which translates to better efficiency.

But what if you're not in a position to invest in a new system? Let's take a look at how to improve the efficiency of your existing HVAC unit.

Change HVAC Filters

Immediately improve efficiency by changing the air filters in your HVAC unit. As the system runs, it pulls air through the filters. Over time, the filters clog with dust, lint, and other debris.

This reduces airflow, making the system work overtime and consume more fuel. The dirtier the filter gets, the harder the unit works, the more energy is wasted — and the higher your utility bill. Plus, dirty filters cause indoor air quality to deteriorate, too.

Changing the filter on a regular basis reduces the unit's workload and increases efficiency. Check your unit for specific recommendations.

Coil Cleaning

Air filters aren't the only component of an HVAC unit that require regular maintenance. Coils also get dirty and need to be cleaned regularly.

Units rely on two sets of coils : condenser and evaporator. Condenser coils (found outside the building) distribute heat, and evaporator coils (found inside the building) cool the surrounding air.

Just like air filters, when these coils get dirty, they cause the system to work harder and consume more fuel, thus decreasing energy efficiency.

Dirty coils also mean the unit wears down faster. Clean condenser coils and evaporator coils at least twice per year, usually in spring and mid-summer.

Lights

Light can affect your HVAC unit's efficiency. For instance, if an outdoor unit is located in a spot that receives direct sunlight for most of the day (i.e., a west- or south-facing location), it may overheat.

This causes the unit to work harder and waste energy, reducing efficiency. If possible, choose a shaded location for outdoor components of your HVAC system.

Indoor light can also play a role in energy efficiency. During summer months, encouraging building tenants to keep curtains or blinds closed during the warmest, brightest parts of the day helps reduce indoor temperatures. This means your unit doesn't have to work as hard to cool the building.

Conversely, during the colder months, keeping windows uncovered can help raise indoor temperatures naturally. Your HVAC unit will need less energy to heat the building.

Self-Service Thermostats

A programmable thermostat allows the unit to self-regulate. When the temperature rises or drops, the thermostat responds by adjusting automatically.

Many thermostats can be controlled remotely, allowing you to raise and lower temperature from any location with an internet connection. Even a few degrees difference in settings can lead to a significant reduction in energy consumption over time.

Commercial HVAC Maintenance: Should You Repair or Replace?

Tue, 12 Jul 2022 13:55:10 GMT

Uh oh. Your building's HVAC system isn't working the way it's supposed to. What now?

It's a common question, especially when temperatures rise and your HVAC system is working hard to keep your building at a comfortable temperature. That additional workload means that, all too often, business owners and facilities managers are left with a tough call: Should I repair or replace my HVAC?

A commercial HVAC system that's malfunctioning, but hasn't experienced a total failure, presents an especially challenging conundrum.

There's no one right answer to this question, as each situation is unique. But investing in a new HVAC system is, well, an investment, so the choice can be difficult to make. Fortunately, there are strategic ways to approach this commercial HVAC maintenance question.

Here's what to consider when deciding whether to repair or replace your HVAC.

HVAC Evaluation

Start by taking a look at your HVAC system's age. Of course, you'll want to account for variables such as consistent maintenance, but HVACs do have a general lifespan.

According to the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) standards database , the average system lasts for about 15 to 20 years with proper maintenance. If your system is nearing the end of this time period — or is older — it may be time to upgrade and replace, rather than repair.

However, each situation is different. Some systems can continue running efficiently for longer, thanks to diligent maintenance. On the flip side, other HVAC systems may reach the end of their lifespan more quickly.

The following factors may account for more than simply age, when weighing a replacement versus a repair:

Key components' quality level; high quality components may lead to a longer lifespan, while lesser-quality or budget components may shorten a system's working life
Size of the system in proportion to the space being heated and cooled; an undersized system has to work harder, which can greatly accelerate decline
Maintenance history; a commercial HVAC system that's been diligently maintained may have a longer lifespan than one that's been poorly maintained
Usage demands throughout the year and climate zone; systems that work harder at certain times of year may wear out faster, as many units in certain climate zones (for instance, bitterly cold winters and humid, hot summers)

Pricing Differences

Has your commercial HVAC system already undergone several major repairs? If so, it may be time to consider a replacement.

Of course, all systems need regular preventative commercial HVAC maintenance. That's a normal requirement for any system to keep running effectively and efficiently. But an HVAC that requires reactive maintenance — that is, when repairs are needed to simply keep the system running — is a different story.

When an HVAC needs constant repairs just to keep going, you may find yourself in an expensive cycle. And frankly, in most such cases, the costs will only continue to mount.

Repairing an Existing Unit

When deciding on replacing versus repairing, take the following costs into consideration:

In-house man hours needed to respond to an HVAC issue
Repair services necessary to get the system back up and running
Downtime of business while the HVAC is broken

If you find yourself sinking money into reactive repairs, rather than preventative maintenance, it may be time to end the cycle. It may simply be more economical to replace the unit.

Buying a New Unit

There's one more key consideration when deciding whether to replace or repair a commercial HVAC system: energy efficiency. Simply put, most newer HVAC units use less energy more efficiently, which saves on energy costs.

That means that a new HVAC can offset the cost of replacement. Over time, the savings will continue to grow. Consider that technological innovations offer savings in another area, as well, such as repairs. New HVAC tech reduces the maintenance costs that can easily cycle out of control with older units.

When thinking about efficiency, consider Annual Fuel Utilization Efficiency or AFUE. This number is calculated as a percentage, and found by dividing the amount of fuel needed by the amount of heat produced by an HVAC unit. For example, a unit with 70 percent efficiency means 70 percent of fuel energy is used for heating. The other 30 percent of energy is lost.

Older HVAC units tend to be less efficient, which means they consume more fuel to heat or cool a building. This leads to a much larger carbon footprint, as well as higher energy bills.

In contrast, higher efficiency means that when an HVAC uses fuel, a higher percentage of energy is available to heat and cool the building. Replacing an inefficient system with a more efficient system can save money over the long run.

How to Install a Boiler

Thu, 30 Jun 2022 22:07:50 GMT

Is your business located in an older building? Are your margins taking a hit from rising fuel prices? Is your water not heating properly? If so, you may benefit from installing a new, efficient boiler to heat your water and air.

Many buildings use inappropriate heating systems. Old buildings use outdated systems, and other buildings may have boilers that are too small or excessive for the space. It's all about determining what is most appropriate for your business. Some industries depend on powerful heating systems where hot water is crucial, like restaurants or manufacturing. And all companies in Illinois know central heating is critical for the winter months. Whether your current heating system is failing or you are looking for a space and cost-saving option, investing in a new boiler will end up saving you in the long term.

While you may be capable of handling some steps on your own, it's highly recommended to hire a contractor to perform the installation. A contractor will ensure the job is done safely and in a timely manner. Plus, you would eliminate the need for a professional to check the gas connection, if applicable, and inspect your finished work.

If you're looking to do some work on your own, or just curious about how to install a boiler and how it can help you save money, here are some steps and considerations taken during boiler installation.

How Long Does Installation Take?

As a business owner, you likely have a lot on your plate already. Hiring an expert will cut down on time, provide maintenance, and help determine the most cost-effective option for your company.

If you're switching out a similar type of boiler, then the contractor can easily get the job completed within one day. If you're completely switching up the system, the work may take a couple of days if complications arise. Your contractor can give you an estimation upon inspection before the work starts.

Selecting a Boiler

When choosing the best boiler, consider your space limitations, budget, water consumption, and total area of the building. This will be important to determine the overall lifetime costs of the new appliance.

As a business owner, your main concern is likely cost-efficiency. Gas-powered boilers are the most popular as electric and solar are typically much more expensive. You will also need to determine whether you need a conventional, system, or combination boiler. The boiler type will depend on the total area needing heat and the amount of space you have for the boiler.

If you're stumped, a contractor can help recommend the best size, system type, and fuel type for your space.

Boiler Location

If you're replacing an old boiler, you likely already have a setup in place for a new one. However, this doesn't mean it's the ideal location depending on the type of boiler you choose. This may be the perfect opportunity to find a better spot for your new system.

What matters is your boiler location is:

Near the water line
Near an electrical outlet
Near a ventilation source
Located on a level surface
Accommodating for the size of the boiler

Pipe Configuration

After removing the old heating system, you can start fitting the new one. You can take this chance to remove any old or unnecessary pipes or clean any existing ones still good to use.

Mount the new boiler and begin connecting the unit to the corresponding pipes in different areas of the building.

Once the right pipes are attached to the unit you can begin placing the return pipes. Different types of boilers will need different connections. For instance, a conventional boiler connects to both a hot and cold water tank.

Flue Installation

Different boiler types will have different ventilation requirements, but all boilers need proper ventilation. Adding a flue is a common way to vent exhaust out of the building, usually through a chimney. You can also create a wall or roof vent if needed instead.

Attach Gas Line

Since gas-fueled boilers are most commonly used, you will need to hook up the boiler to the main gas line to fuel it. This step is best left to the experts for safety reasons.

Testing

Once everything is set, you can start up the boiler! This is a crucial step to evaluate whether all the work was done correctly. Your boiler controls central and water heating, so start by checking thermostats and all faucets in the building. The boiler should be producing hot air through the building and hot water to each water source.

Check back to the boiler as it starts to run and make any adjustments as needed. If everything looks okay, then you're good to go!

After Installation

At this stage, you can rest easy knowing you have a new heating system in place! Your contractor will take away any additional worries by ensuring everything meets all regulations and runs correctly.

Even with a new system in place, it would be wise to ask your contractor about annual maintenance programs. Have your favorite contractor return each year to inspect and clean your boiler system to retain the most efficient product possible.

Backflow Device Testing

Thu, 30 Jun 2022 21:43:12 GMT

Benefits of Backflow Testing

The State of Illinois mandates commercial backflow testing , but that doesn’t mean the process has to be difficult or unrewarding in other ways. Getting your backflow test done with 1 Source means you receive:

Cost Savings: The cost of testing is affordable, and will protect you from larger fines if annual testing is not completed.
Health Benefits: By far the most important benefit is protection from potential life-threatening conditions. Catching problems with backflow devices will prevent hazardous materials from entering a water supply before they can cause harm. Regular testing will grant a peace of mind from having to worry about endangering your water supply to your business.
Cleanliness: Not only will your water remain free of harmful substances, but you will stop further spread of contaminated water throughout the community. This is why backflow testing is required by the state of Illinois.
Easy Scheduling: 1 Source Mechanical makes it easy to schedule your annual appointment with little interference with your routine. We’ll even file the paperwork with the appropriate municipality so you don’t have to worry about the extra steps of remaining compliant.

Why is Backflow Testing Important?

Annual backflow testing, also referred to as cross connection control by some municipalities, may be more important than you realize. If you’re familiar with the number of cross connections that exist, you will know the potential sources of backflow issues at your business. Sprinkler systems, fire protection devices, and swimming pools are just a few examples of cross connections. These sources can expose your drinkable water supply to harmful chemicals or human and animal waste if backflow occurs.

A small change in water pressure can push or pull contaminated sources into the wrong direction, resulting in polluted potable water sources. A simple call to us will ensure this never happens. Plus, if you have any issues, we will be able to catch them early and make the necessary repairs.

What Happens if I Don’t Test My HVAC Regularly?

Ignoring yearly maintenance may cause interruptions to business operations and higher expenses for costly repairs down the road. Save your money and keep everything running smoothly by enrolling in an annual maintenance program with 1 Source Mechanical!

How Do HVAC Systems Work for Commercial Buildings?

Mon, 02 May 2022 18:45:47 GMT

E xplaining How Commercial HVAC Systems Work

How do HVAC systems work... and can they be automated? If you've ever asked yourself this question, you've probably noticed that the answer can seem a bit complex. Add in an explanation of how building automation systems tie in to HVAC operations, and the number of acronyms alone is enough to make anyone's head spin.

But it doesn't have to be complicated. In a nutshell, a Building Automation System (or BAS) is a way to automate and enhance control of your building's electrical, water, mechanical, and ventilation systems, including heating, ventilation, and air cooling or HVAC. A BAS offers an interface that allows you to easily adjust settings, get status updates, and identify any performance issues from one central platform.

Read on to learn more about how a BAS makes your building's system easier to operate.

How Does a Building Automation System Work?

Along with automating HVAC operation, a BAS functions as a user interface between you — the user — and your building's HVAC system. The BAS makes it easier for you to control your HVAC system , from changing settings to checking performance to troubleshooting.

Automation systems have multiple components, including:

Inputs and Outputs: Sensors and other devices such as switches, relays, and thermostats send and receive data and commands
Field Controllers: Receive inputs and control outputs accordingly
Supervisory: Manage communications between the different components
Server and Application: Collects and stores data from supervisory components, then delivers information to the user interface

These components utilize a combination of software and devices that work together to make your life easier. A BAS automates your building's HVAC system, providing you with access when needed and making troubleshooting simpler.

Benefits of Building Automation Systems

A building automation system makes that job easier. Not only does a BAS automate many processes, it provides you with data you need to troubleshoot and avoid problems. This allows for continuous improvement.

But along the obvious plus of automating HVAC, mechanical, electrical, and other operations, building automation systems offer a number of benefits. Among the most significant? Lower energy costs.

A BAS will run your HVAC more efficiently. Sensors and timers guide system automation, which helps reduce energy waste and lowers your bills. Plus, a BAS can collect information on your building's energy usage patterns, which will help you make informed decisions that can both save money and reduce your building's environmental footprint.

Installing a BAS will also enhance comfort. No matter the time of year or the weather conditions, a BAS will keep your building at the right temperature and humidity level, optimize air flow, and automate start and stop times, increasing occupant comfort. This improves safety, health, and well-being... and when workers are more comfortable, they tend to be more productive.

And speaking of safety, a BAS can improve indoor air quality. Monitors keep track of temperature and humidity levels, mitigating conditions that lead to contaminated air (which can exacerbate allergies and respiratory issues). Carbon monoxide and carbon dioxide monitors also help keep building occupants safe.

As an added benefit, a BAS will allow you to monitor your HVAC performance. Not only will troubleshooting be easier, you'll be able to pinpoint potential issues before they arise. This can help lower maintenance costs and reduce the need for expensive repairs, as well as eliminate the downtime associated with break-downs.

Finally, a BAS allows you to control your HVAC system remotely. When a BAS is connected to the cloud, you can access information and controls anywhere there's an internet connection. Automation lets you stay on top of issues in real time, so you can be proactive instead of reactive.

Control System vs Building Automation System

What's the difference between a control system and a BAS? While they do some of the same things (and the control system can actually operate independently of the BAS), they're not the same.

Rather, a control system is part of a BAS. This component's function is to control the inputs and outputs, as well as the field controller. Here's how it works:

An input device — such as thermometer or a wall switch— sends a message (a status update or feedback) to a controller
The controller may be a digital device or a pneumatic device, depending on the type of BAS
The controller then generates an output that leads to a task; for instance, if a wall switch is flipped, a fan will turn on, or if a thermometer reads a temperature below a certain level, the heat will turn on until a target temperature is reached

Is a Building Automation System Worth It?

The right building automation system offers a number of benefits, from lower energy bills to remote monitoring, better indoor air quality to enhanced comfort. A BAS will help your HVAC system operate in the most efficient manner, lowering operating costs and making maintenance easier.

A key to success lies in "future proofing" your BAS. When systems are integrated, you'll be able to get the full potential from your BAS. When used properly, your BAS will pay for itself through lowered energy and maintenance bills.

What is Air Balancing and Why Does It Matter?

Thu, 14 Apr 2022 19:13:44 GMT

Commercial Air Balancing

No matter the temperature outside, you want to be comfortable inside. When your HVAC system is properly balanced — with all of its components working together efficiently — that means a steady year-round temperature in every room, the right amount of airflow, and predictable energy bills.

But what happens when your HVAC is out of whack ? You may notice fluctuating temperatures between rooms, drafts or hot spots, too-high humidity, and other issues that lead to discomfort. Unfortunately, an unbalanced system can also create safety risks.

The solution lies in commercial air balancing.

Why Air Balancing Matters?

An unbalanced HVAC system leads to positive or negative air pressure issues. It's all about achieving even airflow throughout the building... but even well-maintained systems can experience pressure issues.

How do you know if your system is off-balance? Along with drafts, hot or cold spots, and increasing humidity, you may notice:

Whistling sounds
Doors that open and shut by themselves
Doors that are difficult to close
Condensation on the inside of windows
Rooms that feel stuffy or stale
Rising energy bills
Frequent hot and cold cycling

Uneven air flow can lead to uncomfortable conditions. But an unbalanced system can also increase risk to both property and health. High humidity levels encourage mold and mildew growth , and can lead to pollen and dust build-up, all of which can negatively impact respiratory health .

Benefits of Commercial Air Balancing

Commercial air balancing will allow your HVAC system to distribute air effectively and evenly throughout the building. This eliminates negative or positive pressure spots — and that means greater comfort. In other words, no more hot spots in summer, no more unpleasant drafts that lead to mysteriously closing doors, and no more chilly rooms in winter.

A balanced system also means better indoor air quality. Reduced humidity levels don't just result in a fresher, more pleasant atmosphere (although that's another benefit of commercial air balancing). A balanced system also means fewer containments, like mold spores, pollen, or dust to trigger allergies and respiratory issues.

Finally, a commercial air balancing service will help lower energy bills. A balanced system means consistent temperatures throughout the building, so your HVAC system will cycle less. Plus, no one will need to crank the A/C or heat to compensate for fluctuating temperatures.

Commercial Air Balancing Explained

The commercial air balancing process incorporates three components that incorporate testing, adjustment and balancing:

Testing assesses HVAC performance by measuring temperature, pressure, velocity, rotational speed, electrical characteristics, and air and water quality
Adjustment achieves the best possible efficiency by optimizing device performance
Balancing regulates optimal air flow by correlating all components of the HVAC system, so they work in harmony

Why You Need an HVAC Inspection Annually

Fri, 25 Feb 2022 16:00:39 GMT

Don't Wait, Get Your HVAC Inspection Today

HVAC systems are important to your business operation. HVAC is the unit in your building that provides heating, air conditioning, and ventilation. If your HVAC system is not working properly, you will most certainly know. Your environment will become uncomfortable fairly quickly.

What happens when your HVAC system stops working in the middle of the most important workday of the year? What happens when you need to shut down your business for a few days because your HVAC system needs big repairs?

This can all be avoided with routine HVAC inspections from our licensed contractors at 1 Source Mechanical .

Routine HVAC inspections are critical to keeping your business up and running . Regular inspections keep your HVAC unit in working condition, your building comfortable, and will also help maintain the life and longevity of your HVAC system.

Regular Maintenance can also ensure that your HVAC is being energy efficient, to keep your utility bills down.

Routine HVAC inspections are critical to the upkeep of your building.

What Happens During an Inspection?

When you need an inspection on your HVAC system, 1 Source Mechanical will send out one of our contractors to service your system.

Our 1 Source Mechanical contractor will:

talk with you about what is happening with your HVAC system, and any issues you have been experiencing
help you make a plan on how to move forward in servicing your heating, cooling, and ventilation system
run diagnostic tests on the HVAC to see how it is running, and if it is energy efficient
test air quality in all zones
test thermostats
check all air filters
check for leaks in coils, ducts, and pipes
check for proper airflow
check the belts, fans, and bolts
check the pilot and ignition
check the exhaust, fans, and circulation
check all the wiring
assure that proper heating and cooling mechanisms are working right

Our contractors will then discuss the findings and health of your HVAC systems with you, and begin the necessary repairs. Once you and your contractor have reviewed the HVAC system, our contractors will start repairs on your system, and have it up and running in no time.

Common HVAC Problems

Cooling and Heating Issues: Most times, this means that your system is either out of refrigerant, or the HVAC system is frozen

Dirty or Broken Air Filters: Air ducts can collect a lot of foliage and other debris over the year. They can also collect a lot of dirt and dust. Making sure that the air filters are clean, and in good working condition is essential to keeping the air clean, and your HVAC system running smoothly.

Thermostat Issues: If there are areas in your building that are not heating or cooling properly, you could have thermostat issues. If your system stops working altogether, this can also mean thermostat issues.

Loss of Efficiency: If you notice your utility bills spiking, it is most likely because your system is no longer running efficiently. Therefore, routine check-ups are important to maintaining your HVAC system

Lower Air Quality: If your HVAC system is not running properly, you will notice a difference in the air quality in the building. It is important to keep your HVAC system running to promote clean air circulation

Loose Wire Connections: Over time, the HVAC system can contain some loose wires and electrical connections. These can cause your HVAC systems to act up. It can also cause an electrical fire if not attended to.

When Should I Get an Inspection?

You will want to make sure that you are getting an inspection at least once every six months on your commercial HVAC system. If you have a new and properly maintained HVAC system, you can also schedule a yearly inspection although six months is recommended. Proper function of your heating, cooling, and ventilation systems, will not only keep your building comfortable but also keep more money in your pocket.

It is always a good idea to get an inspection before you turn the heat on and before you turn the cooling on. By getting inspections at these critical times will assure that you will have a healthy working HVAC system for the seasonal weather.

HVAC inspections are important when buying a new building. When investing in a new commercial space, you do not want to run into HVAC systems. By having one of our contractors come out to service your potential building before the sale, you could save yourself a lot of money and headache.

If your building hasn't been occupied for some time, you are going to want to make sure you have it inspected. Buildings that sit vacantly can have a lot of dust and debris that settle. You’ll want to make sure you get your vacant building HVAC inspected before turning on the system.

Why Are HVAC Inspections Important?

Every business wants a comfortable and healthy work environment for their employees and for their customers. A clean and comfortable temperature in the office is the best way to make your business thrive and keep people happy.

Your commercial building is a huge investment. You want to make sure you are protecting your investment and that the HVAC is operating properly.

Neglecting your HVAC system can lead to bigger issues that will end up costing you a fortune in the long run.

How Much Do They Cost?

HVAC inspections can range from $100 to $300 if your HVAC system is in good condition and running properly. This is usually just a routine check-up.

More serious HVAC problems can cost anywhere from $100 to $3000, depending on the damages and repairs that are needed.

Condenser Coils vs Evaporator Coils: Key Differences

Wed, 02 Feb 2022 23:03:53 GMT

Your commercial HVAC is an important piece of your business. It helps to keep your employees cool while working, as well as any customers. Keeping your employees and customers comfortable allows your production to move at a smooth pace, while customers are relaxed while being at your place of business. But sometimes your commercial HVAC may run into some issues. It can be helpful to be able to identify the issue and that starts with understanding the differences between condenser vs evaporator coils.

Understanding Condenser vs Evaporator Coils in the HVAC Unit

When your HVAC unit begins to make a noticeable noise or begins to not work properly, it’s time to figure out what the issue could be. When this happens, most HVAC owners will believe that something is wrong with the HVAC’s ability to supply a certain level of coolness. But that’s not how HVAC unit’s work.

HVAC units create a comfortable temperature by moving the heat that is already there, not by creating coolness. The temperature drops based on how much heat is being removed. The two vital coils that make this process work are condenser and Evaporator coils. To be able to accurately identify the issue, it’s vital to understand the role each coil plays.

In a commercial HVAC system, the differences of both condenser and evaporator coils are more than just where they are located. When your HVAC unit begins to falter, it can usually be that one of the coils is responsible. Both coils play a role in removing heat from a space. The evaporator and condenser coils within a HVAC system are the parts that are taxed with doing the heavy lifting of extracting heat and transferring it outside. However, these coils work in opposite ways.

EVAPORATOR COIL

To understand how the coils differ, you need to understand how each coil functions, and the role it plays within the HVAC system. Let’s start with the evaporator coil. The evaporator coils job is to extract the heat from indoors and add it to the refrigerant. So, it makes sense that the evaporator coil is located indoors, either inside or near the air handler. Now, you can begin to look at the parts that the evaporator coil works with to complete its assigned task.

Before we get to the evaporator coil, there is an expansion valve. The expansion valve is tasked with receiving the high-pressured refrigerant from the outside condenser. Through this process the pressure that is put on the refrigerant is relieved, helping to keep it cool. The cool liquid refrigerant will then be able to flow into the evaporator coil.

Next, it’s time to look at the job of the air handler. The air handler has a blower fan that will blow air across the evaporator coil. It is then the cold refrigerant’s job to absorb the heat from the air. This causes the air to be condensed into water. The water will then drip into the condensate drain, which moves to the outside. Once this process is completed, the now cooler air flows through the ducts into the spaces where the cooler air is desired. Now let’s look at the condenser coil and the role it plays in the process of dehumidifying your space.

CONDENSER COIL

In trying to understand how the operation of the condenser coil vs the evaporator coil differs, it’s time to get educated on the role the condenser coil plays to keep your space comfortable. When looking at the condenser coil vs the evaporator coil, you’ll quickly realize that they are similar in design. However, their functions are different. We know that the evaporator coil extracts the heat from indoors— but it’s the condenser coil that releases the hot air into the outdoors.

The amount of heat removed from the space that is being cooled, is extracted, and compressed into refrigerant vapor. This hot vapor is quickly released once the refrigerant circulates into the coil and is then condensed into liquid. Once the refrigerant begins has the heat released, a fan within the HVAC unit will blow air through the condenser coil allowing the heat to be release outside.

Unlike the evaporator coil, the condenser coil is in the outside unit, with other vital parts like the compressor. They are joined by multiple pipes and valves all functioning to fulfill their purpose of cooling your space to a comfortable temperature.

Now armed with the understanding of the differences of the condenser coil vs the evaporator coil, it’s time to see how you can ensure their maintenance so that you problems don’t arise in the future.

Coil Maintenance

Like most machinery, regular maintenance is often necessary to keep a system running. A HVAC system is no different. This goes for both the evaporator and condenser coils as well. When it comes to regular maintenance, there is no difference between the two coils. Due to their roles in keeping your space cool and comfortable, both coils can be stressed and start to fail. Even if your HVAC system hasn’t stopped working, one of these coils could be keeping your HVAC unit from working efficiently. If your system isn’t working at maximum efficiency, it could end up costing you more money on your electric bill. Therefore, regular maintenance is recommended.

How Much Does a New Commercial HVAC System Cost

Wed, 08 Dec 2021 15:04:13 GMT

Out of nowhere—you’re HVAC unit isn’t working correctly. Now, you have employees coming to you complaining about the temperature and their working conditions. Next, it’s your customers who are paying you a visit with their complaints too.

It’s time to make a call about your HVAC unit and get trained professionals to come out and evaluate your unit . But before you do, you’ll want to know just how much a new HVAC Unit could cost you—and what other options you could have.

How Much Does a New HVAC Cost?

The price of new a HVAC system can vary based on multiple factors. Whether it’s the brand, the size of the unit, or the cost of labor, these factors can determine just how much a system can cost. Typically, you can expect to pay anywhere from $1,000 to $10,000 dollars for a new HVAC system.

This can be a hefty sum for some businesses to pay, and you’ll most likely be searching for other alternatives to buying a new HVAC System.

Thankfully there are other options available to most consumers. Once you have trained professionals come to inspect what is causing your problem, they may offer repairs.

Evaluating the Problem: Repair or New?

A trustworthy professional will evaluate your HVAC system and let you know if you are better off buying a new system altogether— or repairing your current HVAC unit. HVAC repair is usually possible without needing to replace the entire unit. Though a business may see the slightest issue as the end of an HVAC unit’s life, often, a repair is still possible.

Depending on the issue plaguing your system, a professional technician will be able to evaluate the unit and understand what repairs should be done to get you back up and running. Oftentimes the problem is something that is repairable and could end up saving your business money. It can also save time. Most businesses and people will want to quickly get their HVAC back up and running in a timely manner for their employees and customers. But when should you get your HVAC system repaired, and when should you buy a new one?

Ultimately, your trusted HVAC professional will inform you which option is more cost effective. Repairs can sometimes almost be as much as a new unit, and it can make more sense to just start with a brand-new system. That’s why it’s important to find an HVAC contractor that you can trust and will tell you what’s best for your wallet.

Walk In Cooler Repair or Replacement

Tue, 19 Oct 2021 21:24:21 GMT

If you own or work in a restaurant, you are already used to making trips to the walk-in cooler to get invaluable items to complete the orders that keep your business running. However, what do you do if that cooler stops working?

This is a huge issue that may require you to close down the restaurant until necessary repairs are made, and it could set your business back. That’s why it’s important to recognize when walk-in freezer needing to be repaired or replaced to both avoid inconvenient closings or to save money when your cooler may need a simple fix versus a whole replacement. Keep reading for some helpful information on knowing the difference.

How a Walk-In Cooler Operates

In order to properly assess what issues your walk-in cooler could be facing, you’ll need a basic understanding of how it operates. A walk-in cooler functions with an HVAC unit. This unit will be larger than most, in order to obtain the right temperature in a larger space. There are multiple types of walk-in coolers. A self-contained walk-in, is when the refrigeration system is all in one unit, with the evaporator and condenser. A remote condensing walk-in will house the condenser unit elsewhere and be separate from the evaporator. Lastly, a multiplex walk-in will use a centralized system that will house multiple condensing units and evaporators. Depending on which type of walk-in cooler you have, the process and cost of repair can vary, however, all of them would involve repairing or replacing the HVAC unit. So when should you repair or replace your walk-in cooler?

Replace or Repair?

Chances are your walk-in cooler is crucial to your business or operation. So, when you start to experience any issue, you will want to call to have a professional assess the situation. The standard life expectancy rate for a walk-in cooler is roughly 15 years. If you’ve owned your walk-in for less time than that, you should be thinking about repair.

Repairing a Walk-In Cooler

HVAC repair is usually possible without needing to replace the entire unit. Some businesses will see the slightest issue to their walk-in cooler as the end of its use, however, repair is usually possible. As long as a professional technician can find a way to access the cooling system, there should be an opportunity for repair. A professional can have your cooler back to normal in no time, sometimes with only a few hours of work. Let’s take a look at a few common issues that can hinder your walk-in cooler from operating correctly.

Common Issues

Just like with other HVAC units, a walk-in cooler can run into multiple issues during its life. A professional technician will be able to assess the problems that are plaguing your unit. Some common issues can be your condenser coil, evaporator coil, or leaks from poorly insulated panels.

A condenser coil needs to be well ventilated in order for the heat in to be removed. If the coil has its airflow obstructed by debris or dirt, it can insulate the heat and reduce airflow.
An evaporator coil will help regulate the temperature inside of your cooler, ensuring that the temperature is where it needs to be. However, when the evaporator coil isn’t defrosting correctly, it can cause an increase in temperature and start to thaw your product.
Insulation panels keep cool air inside of the unit and will help maintain the correct temperatures. However, things like age, buildup, or moisture on panels could be causing heat to get inside your unit.

With a quick call to your local HVAC repair company, you can usually fix almost any issue in the system. Repairing a walk-in cooler can be pricy, though it is still much cheaper than replacing it altogether. Though sometimes, it might not be worth it to repair your unit.

Replacing a Walk-In Cooler

While most issues can be fixed, sometimes the unit is beyond repair. Here are a few instances where it can make more sense to replace your walk-in cooler.

Age

While you can still repair a cooler that’s 15 years old or older, it might not be the most efficient option. By this point, your walk-in cooler might not be as energy efficient as a newer model and could actually be costing you money.

Cost of Repair

If you find yourself frequently shelling out money for repairs, or if the cost of a repair is too great, it can be cost effective to replace your walk-in cooler. While replacing it might be more expensive today, the cost of continuing to repair a troubled unit could end up being more costly.

Leaks

If your unit is constantly leaking, it can be a safety hazard for you and your employees. It’s always the right choice to make sure your business runs smoothly and safely. If you continue to run into this issue over and over, the best option might be to replace your unit.

As always you should call your local HVAC repair service to get a professional opinion as to what your best option is. Repair will be your first choice to get your walk-in cooler running properly again. But as we’ve demonstrated, it’s not always the case. That’s why it’s important to let a trusted professional guide you to making the best decision possible.

Commercial HVAC Systems 101

Wed, 15 Sep 2021 15:18:18 GMT

With efficiency upgrades and technology updates, the HVAC servicing and management industry is rapidly evolving. As a result, HVAC services are becoming increasingly complex, requiring industry know-how to properly manage.

HVAC technicians must provide a wide range of HVAC services to best meet their clients' needs. In the content below, we explore different HVAC service management functions that your technician may offer and three components that make for a great HVAC service manager!

HVAC Service Management 101: What Are the Services Offered?

When it comes to HVAC service management, you can compartmentalize offered services into three categories: HVAC installation, HVAC maintenance, and HVAC repair.

#1. HVAC Installation

Installing an HVAC unit begins with selecting the right unit type for your building that also satisfies both building and fire codes. With your unit type purchased and acquired, you must successfully undergo a site assessment of the HVAC system. This allows a professional to examine the location and HVAC system for best utilization and compliance with required safety codes.

Ready to install? HVAC installation procedure includes the following steps:

· HVAC equipment installation includes labor, materials, and any ancillary costs such as safety features needed by the customer.

· HVAC supply installations supply systems that distribute coolant to other HVAC components. This may include water pumps in ice machine or air conditioning units. HVAC supply installations may also include the installation of refrigerant lines.

· HVAC system start-up ensures HVAC equipment is operating correctly (includes a check for leaks, and dirt accumulation.)

#2. HVAC Maintenance

Like a vehicle tune-up or annual check-up with your primary physician, HVAC service management includes both preventative and active maintenance, or a tune-up.

HVAC preventive maintenance includes scheduled tune-ups, filter replacement, and air cleaner checks. The goal is to ensure you HVAC unit is working at its optimum level. Preventative maintenance also includes regular checks of electrical components and inspecting HVAC components for wear or damage. At this time, your HVAC service management team can make any necessary repairs.

An HVAC tune-up entails cleaning the HVAC equipment's interior, loosening bearing surfaces, checking belts, and installing new filters. Tune-ups are highly recommended to maintain peak efficiency in HVAC systems. Additional services also include HVAC check-up and inspection.

#3. HVAC Repair

HVAC repair is the third category of HVAC service management functions and requires the timeliest response and action. Depending on the nature of your HVAC problem, HVAC services can include replacing air conditioner units and repairing or replacing HVAC parts and compressors.

While HVACs are critical for keeping your building cool, furnaces are equally imperative in colder climates. Furnace Repair is also an HVAC service management function and requires immediate repair. Hiring a qualified HVAC contractor to perform repairs will ensure that your furnace is operating as it should.

Additionally, HVAC repair includes emergency services to continue HVAC operations and provide immediate relief for the customer during a power outage or any other unit issue. A broken-down HVAC can be costly for food, pharmaceutical, and any other industry that requires controlled temperatures for optimal functionality and productivity. As a result, HVAC service management companies offer emergency repair services that are just a quick call away.

What Makes a Great HVAC Service Management Company?

Hiring an HVAC contractor to manage HVAC services can be intimidating for some, but it's important that you consider your HVAC needs before deciding on how involved you want the HVAC company to be in managing these systems.

Not all service and management companies offer the same, high-quality services. That's why it's important to partner with an HVAC service management company that provides efficient and timely services for every maintenance, installation, or repair job needed. Wondering what makes a service management company rise above the rest? Here are a few components to look for:

#1. License and Registration

Before looking at anything else, determine if the HVAC servicing company is both licensed and registered for the industry. It's imperative that you hire only licensed professionals who are up to date on HVAC advancements in technology. They will be able to properly troubleshoot your system or provide preventative maintenance such as HVAC tune-ups and HVAC cleaning.

In addition to a license, make sure the management company has registration with the National Air Duct Cleaners Association (NADCA). NADCA members are committed to meeting industry standards in providing quality HVAC services so they will be most qualified for your project.

#2. Industry Knowledge and Experience

HVAC service providers must have the knowledge, expertise and understanding of HVAC systems of various makes, models, and years to ensure HVAC services run smoothly. A company with industry experience and knowledge will be able to diagnose problems quickly, provide appropriate solutions, and make the process as seamless for you as possible.

Additionally, by hiring a qualified HVAC contractor to perform repairs will ensure that the HVAC system is operating correctly and efficiently, preventing future issues from occurring.

#3. 24/7 Emergency Services

Top-notch HVAC service management providers offer 24/hour emergency HVAC services. For example, if your HVAC system breaks down during a summer heat wave or in the middle of a winter ice storm, you can call for assistance and they will be there to fix the problem as soon as possible.

This service is critical for all businesses, but especially for food and pharmaceutical industries where products could spoil under different temperatures.

Backflow Testing: Everything You Need to Know

Tue, 20 Apr 2021 19:08:50 GMT

We often take water for granted. In commercial spaces, employees typically do not consider where their drinking water comes from, because plumbing systems are kept out of sight (and out of mind).

Neatly stored away, few people plan for plumbing problems until something goes wrong. When an issue arises – especially an issue that could contaminate drinking water – organizations are often left unprepared. Although not every plumbing issue is preventable, proactive steps can be taken to reduce the risk of toxic plumbing troubles.

Backflow testing is one such proactive step.

In the content below, we dive into everything need to know about backflow testing services, including what it entails and why it is so important in preventing toxic plumbing issues.

What Is Backflow?

From toilets to fire-safety sprinklers, water is used in a multitude of different ways. Most individuals don't consider that water is much more than a simple, in-and-out process.

Water is drawn from a source, used, and then transported back into the sewage system. Right?

Yes. However, there is much more involved in the inner workings of your company's plumbing than meets the eye. For example, commercial water systems are divided into two supplies, potable and non-potable. Potable water is drinkable; non-potable water is toxic. As one may imagine, it's critical that these two water supplies remained separate.

In its simplest definition, backflow is the unwanted flow of potable or foul water in the reverse direction. When backflow occurs, drinking water is contaminated. This poses a serious health risk.

Why Does Backflow Occur?

Backflow occurs either due to backpressure or backsiphonage.

Backpressure backflow occurs when the downstream pressure is greater than the supply pressure of the potable water supply within a system. A reduction in the potable water supply could occur when the amount being used is greater than the amount being supplied.
Backsiphonage backflow is caused by negative pressure in supply piping, reversing the normal flow of the system. In this case, water is pushed back through the supply line.

In either case, non-potable water is mixed with potable water, affectively contaminating it.

What Backflow-Prevention Device Do I Need?

Backflow-prevention measures are implemented to prevent backflow from occurring. The specific tools utilized to prevent backflow depend on the risk of contamination. Risk is often categorized into five primary levels:

Risk Level 1: Safe, potable water
Risk Level 2: Aesthetic water quality altered
Risk Level 3: Slight health risk
Risk Level 4: Serious health risk (e.g. pesticides)
Risk Level 5: Critical health risk (e.g. human waste)

The American Backflow Prevention Association (ABPA) writes, “The type of backflow prevention assembly required is determined by the degree of hazard. In other words, the severity of the actual or potential hazard will dictate what level of protection is necessary to adequately protect the drinking water.”

What Is Backflow Testing?

Backflow testing is the process of examining backflow-prevention devices to ensure they are keeping water lines free of contaminants. Testing is required for commercial and residential properties, such as condominium buildings, restaurants, businesses, and other public places.

What are the Backflow Testing Procedures?

Backflow testing follows a series of clear steps:

Water in the tested device will be shut off for a brief period of time, often between 10-15 minutes.
If applicable, fire systems located beneath tested devices will have to be put on test mode.
Testing is completed.
If the backflow device passes inspection, testing obligations are satisfied for a year.
If the backflow device fails inspection, repair or replacement may need to be completed. Some backflow testing businesses, such as 1 Source Mechanical , complete needed repairs immediately after a failed inspection.
Once repair or replacement is completed, the device will be tested once more.

Why is Backflow Testing Important?

Once the ins-and-outs of backflow have been discussed, the significance of testing is clear – backflow testing reveals the risk level of contaminated water.

When Do I Need a Backflow Test?

The Environmental Protection Agency requires that backflow-prevention devices be tested yearly. When a backflow test is due, your county will send out a notice at least one month in advance. Additionally, you are concerned about the safety of your drinking water, contact a backflow testing specialist . It is always best to be safe.

The ABPA further explores why backflow-preventers must be tested regularly:

"Mechanical backflow preventers have internal seals, springs, and moving parts that are subject to fouling, wear, or fatigue. Also, mechanical backflow preventers and air gaps can be bypassed. Therefore, all backflow preventers have to be tested periodically to ensure that they are functioning properly. A visual check of air gaps is sufficient, but mechanical backflow preventers have to be tested with properly calibrated gauge equipment."

Backflow Testing Done Right With 1 Source Mechanical

To meet safety standards, backflow testing must be performed by technicians with the proper skill, equipment, and knowledge of backflow testing procedures. Backflow prevention is not something to ignore – you don’t want contaminated water to catch you by surprise!

3 Types of Commercial HVAC Systems

Thu, 04 Feb 2021 16:34:26 GMT

Are you in the process of constructing a new commercial building, or is it simply time for an upgrade to your HVAC system? Commercial building owners, contractors, facility managers, and other decision makers have a few different options when it comes to what HVAC system they can install in their commercial building. Which one is right for you and your facility? While each type offers unique benefits and potential drawbacks, we will break down the differences between a few of the most popular types of commercial HVAC systems to help you make your decision.

Rooftop Units

Especially common in the industry, rooftop units use many different component types to produce conditioned and heated air, housed within the unit and situated outside on top of your building. Consisting of traditional sets of coils, compressors and fans, this types of unite directly connect to the ventilation system of your building to then distribute that air.

The Pros & Cons of Rooftop HVAC Units

Rooftop units come in a wide variety of types and sizes, meaning there is certainly a unit that will work for your exact needs. With rooftop units, you will be able to heat and cool nearly any amount of square footage with a relatively easy, space saving installation process. Usually only requiring routine maintenance a few times a year, these units are more susceptible to weather damage than other options due to their rooftop location. More expensive repairs may be required from time-to-time as a result.

Multi Splits (Split Systems)

Split systems are so called due to the “split” nature of the unit. Comprised of two cabinets, one indoors and one outdoors, both hold different pieces of the system. The outdoor cabinet houses the compressor, fan, and condenser coil while the indoor cabinet houses the blower, dampers, air handler, and is the point of connection to your building’s ventilation system.

While the outdoor cabinet is usually stored right outside your facility in a discrete location, the indoor cabinet can be stored in several places. Utility closets, basements, and attics are popular options.

There are also two different types of split systems – single and multi-split systems. Single splits are a great option for small spaces such as a small office, café, etc. If you decide to expand your operations later one, additional split systems can be added to serve your new space without creating unnecessary headaches and difficulties. Conversely, a multi-split system is well suited for larger spaces, including buildings with multiple floors.

Pros & Cons of Split Systems

Build for precise comfort and control zoning, split systems are an amazingly efficient and reliable way to heat businesses and office buildings. Typically, they are less expensive than rooftop units and are also highly energy efficient. However, installation can be much costlier, and they are not always the most aesthetic option when outside your building.

Commercial boilers

Noticeably healthier than forced-air heating options, commercial boiler systems limit the amount of air pollutants moving through your building’s ductwork. They are a reliable way to keep customers and employees comfortable for many winters to come.

However, commercial boilers tend to cost more for both installation and repair services than other heating systems. Additionally, regular preventative maintenance, performed by a licensed and experienced technician, is mandatory.

4 Main Benefits of Commercial Humidification Systems Control

Tue, 08 Dec 2020 16:13:36 GMT

Commercial humidification systems provide many amazing benefits to create healthier, more productive workspaces for all.

When we think about a safer, more productive workday, it’s unlikely that a commercial humidification system comes to mind. While this may be the case, failing to implement this technology in your building can mean you are missing out on a whole host of benefits for your building, products, and employees. In this article, we explore just a few of the major benefits of commercial humidification systems.

Reduce Viruses & Bacteria

Perhaps the most important benefit of commercial humidification is its ability to reduce the number of airborne particles. Many illnesses, including COVID-19, are quickly spread through these airborne particles and can travel through the air over great distances.

Commercial humidification introduces moisture into the air, which causes these particles to drop to the floor quickly, reducing the potential for spread of viral or bacterial cells over large areas.

Proper humidification can also ground mold spores and dust, keeping the building cleaner and more sanitary in general for the benefit of all who work in and visit your facility.

Make Employees More Comfortable & Productive

Offices can help their employees become more productive through commercial humidification as well. Maintaining a proper level of moisture in the air can reduce or eliminate dry eyes, itchy skin, asthma symptoms, sore throats, and more.

Extensive research conducted by the University of Oxford found that happy workers (i.e. more comfortable workers) are up to 13% more productive on a day-to-day basis than those who are not. Imagine what a 13% boost to productivity could do for the success of your business. While there are certainly other factors that contribute, a commercial humidification system is definitely a start to making your employees more comfortable and capable of working hard.

Increase the Life of Your Building

In addition to helping the people who work in your building, commercial humidification can also benefit the building itself. From floors and paint to furniture and electronics, the components of your building last longer when they are located in a properly humidified environment. Low humidity can cause wood to shrink, causing damage to furniture, flooring, and windowpanes. Electronics are also susceptible to low humidity, which brings us to our next benefit.

Prevent the Accumulation of Static Electricity

Ideal for data centers, pharmaceutical companies, or any facility with highly sensitive equipment or environmental needs, commercial humidification is an absolute must have. The ideal humidity for a data center is between 40-60%, which can be difficult to keep consistent without proper monitoring and control equipment. By cutting down on the formulation of static electricity, humidifiers prevent damage to servers from electrostatic discharge. It can also help pharmaceutical companies produce high-quality, highly sensitive medications.

Commercial Humidification with 1 Source Mechanical

In short, commercial humidification can help us get back to work more quickly and more productively. If, by the time you’ve finished this article, you’ve been convinced of the benefits of commercial humidification and want to implement such a system at your facility, we are here for you.
