HVAC Assessment

A failing system can be a major inconvenience, especially in the heart of summer or winter. We can determine if your HVAC system needs repair, replacement or basic maintenance and then act quickly. Performing quick fixes on your own may temporarily resolve the problem, but a full inspection may determine an underlying cause that prevents you from having to make a similar repair over and over again.

HVAC Ventilation Configuration

If your business includes commercial kitchen space, properly operating ventilation is vital. Different businesses will need different ventilation systems depending on the industry. Let us educate you and find the appropriate system for your building so you are not overpaying for a complicated unit or not getting the required ventilation you need. We serve as your advisors and problem-solvers for your system.

An efficient commercial HVAC system is one you rarely have to think about. Air and water temperatures stay at the right levels and equipment works as it should. The HVAC has different types and is often the most complex system in any building, but when not functioning correctly, you are likely to notice it immediately. The HVAC system is made of three main components, the heating, ventilation, and air conditioning. All parts are related, and it is important to know all the pieces involved that need cleaning and replacement such as ducts, filters, and compressors. This type of equipment and regular maintenance will help your HVAC system last, but occasionally you will need a full replacement. 

Aging, worn, or malfunctioning HVAC units can drain valuable time and effort from your day. An erratic heating unit, faulty ventilation or inconsistent cooling becomes an unwelcome interruption of your business. At times, regular checks of your HVAC system can delay any major malfunctions, but an outdated or broken HVAC unit needs proper inspection, repair, or replacement from a qualified professional.

At 1 Source Mechanical, we offer maintenance agreements to further optimize your HVAC system's performance and ensure its longevity. Our 24-hour emergency repair service means we're always ready to assist you, from DeKalb to Chicago and beyond. With two locations in DeKalb and Oak Brook, we can reach you promptly whenever you need us.
