Commercial buildings have HVAC systems to keep employees comfortable during work and provide quality air for staff. Every machine will age and begin to malfunction, but understanding the warning signs can help you quickly tackle the issues. Your system could be producing weird noises. Your energy bills could be increasing. It’s best to have a technician look at the system. Here are a few common issues with commercial HVAC systems to look out for.

Odd Noises

Not every noise from your commercial HVAC system is cause for concern. Many of them are normal. For instance, the ductwork can create popping noises when the metal ducts expand from the cold or hot air.

If your HVAC system begins making a noise you’ve never heard, there could be something wrong. Are the heating or cooling units operating louder than usual? The fix could be simple, or it could be something more significant. A small piece could’ve fallen off, causing a rattling noise. Maybe the fan belt is worn and requires replacing. Contact a local HVAC technician to inspect your system and determine the issue.

Inefficient System

Modern systems are more energy efficient than older ones. If your energy bills have risen over the last few months, it’s time to contact a technician to service your HVAC.

There could be problems with your air ducts if you’re experiencing uneven heating and cooling throughout the building. Ask a technician to check the dampers for proper balance and installation. Dampers reduce airflow in one line and increase flow in others to achieve equal distribution.

The age of your system could be causing it to run nonstop. The restricted airflow could be due to dirty condenser coils. This problem isn’t anything an HVAC technician can’t handle.

Unresponsiveness

There could be a few different reasons why your HVAC system won’t turn on. Technicians will first check the thermostat since this is the most popular reason. The new programmable thermostats run on batteries, and dead batteries are likely the problem. If you change the batteries, but it’s still unresponsive, you may need a new thermostat.

Industrial electrical control panels have many uses, and one of them is providing power to your HVAC system. If the control panel uses the emergency shut-off feature to turn off your system, you must reset it. This reason could be because there’s a more serious problem with the electrical system.

Preventative maintenance can stop most of these common issues with commercial HVAC systems. Ensure you always have your system serviced in the spring and fall to check that everything is operating correctly. This tip will help detect any problems early.
