If you’ve noticed that your commercial HVAC system seems to be running continuously, you’re not alone. Many business owners and facility managers across the Atlanta area have experienced this issue. Not only can it lead to increased energy bills, but it may also indicate a problem with the HVAC system that needs to be addressed.
Help! My Commercial HVAC Never Cuts Off!
Aeras Building Solutions explores some of the common reasons why a commercial HVAC system may never seem to cut off and what you can do about it.
Incorrect Thermostat Settings
The thermostat settings are one of the first things to check when your commercial HVAC system is running non-stop. It’s possible that the thermostat has been set to “fan” mode rather than “auto” mode. In fan mode, the HVAC system will continue to blow air even when the temperature has reached the set point. Ensure the thermostat is set to “auto” so the system can cycle on and off as needed to maintain the desired temperature.
Overworking Due to Improper Sizing
Another common reason for a commercial HVAC system to run continuously is that it is improperly sized for the space it is trying to cool or heat. An HVAC system that is too small for the space will struggle to keep up with the demand, leading it to run constantly. On the other hand, an oversized HVAC system may short cycle, turning on and off frequently, leading to energy inefficiency and premature wear and tear.
Dirty Air Filters and Coils
Dirty air filters and coils can restrict airflow and cause the HVAC system to work harder to achieve the desired temperature. When airflow is restricted, the system may run continuously in an attempt to compensate for the reduced efficiency. Regularly changing air filters and scheduling routine maintenance to clean the coils can help prevent this issue.
Refrigerant Leaks
Refrigerant is essential for the cooling process in air conditioning systems. If there is a refrigerant leak, the HVAC system may struggle to cool the space effectively, leading it to run non-stop in an attempt to reach the set temperature. Refrigerant leaks should be addressed promptly by a qualified Aeras HVAC technician to prevent further damage to the system.
Malfunctioning Thermostat or Controls
A malfunctioning thermostat or control system can also cause the HVAC system to run continuously. If the thermostat is not accurately sensing the temperature or if there are issues with the control settings, the system may not shut off when it should.
Age and Wear
The age and overall condition of the HVAC system can also contribute to its continuous running. Over time, wear and tear can lead to reduced efficiency, making the system work harder to achieve the desired temperature. If your commercial HVAC system is older and exhibits continuous running behavior, it may be worth considering an upgrade to a more energy-efficient model.
