Commercial Water Heater Repair in Aurora

Signs Your Water Heater Needs Repair or Replacement

In commercial settings, reliable hot water is a must. When your system starts to fall short, it can create real problems for your operation. Slow recovery times, water that changes temperature unexpectedly, or signs of corrosion like discolored water may point to trouble inside the tank. Leaks around the base, banging or popping sounds, and rising utility bills are also red flags.


Putting off service increases the risk of a breakdown. Routine checkups can catch minor issues before they grow into costly repairs. If you suspect a problem, scheduling commercial water heater repair early can help keep your facility running without interruption.

Water Heater Not Working?


Perhaps your taps are running lukewarm — or worse, cold. Maybe the temperature is sometimes just right, but other times too cool.


When there's a problem with your water heater, it's time to call the professionals.

Signs you need commercial water heater repair include:


  • Lukewarm, inconsistent, or no hot water. Fluctuating or cool temperatures means it's time to call a specialist.
  • Puddling or dripping water. Dripping or pooling around the water heater might mean a leak. Call a professional immediately to avoid water damage.
  • Discolored water. Rusty water can indicate a corroded tank.

Choosing the right water heater has a direct impact on daily performance, energy use, and long-term reliability. At 1 Source Mechanical, we take a close look at how your building uses hot water, how much demand it sees during peak hours, and how quickly it needs to recover between cycles. From there, we match you with a system built to meet those demands without driving up operating costs.


Here are a few commercial water heater types we frequently install and maintain:



  • Storage Tank Water Heaters – Reliable option for consistent, high-volume use
