Your commercial HVAC system is undoubtedly an essential part of your business. It keeps your building at a constant, comfortable temperature year-round, and ensures that your facility has clean and fresh air to breathe. But these machines are not designed to be constantly running. Just like your AC or heaters at home, the systems are built to shut off when a desired temperature is reached, and only turn on again to get your facility back to that set temperature. If this happens, it could lead to bigger issues down the road, posing the risk of a massive repair bill and lost time and production. Here are a few reasons why your commercial HVAC system won’t shut off, and how to recognize these warning signs before things get worse.
1. Broken Thermostat
One of the most common reasons why your HVAC won’t shut off is an issue with your thermostat’s thermometer. When this happens, your unit isn’t able to correctly identify your facility’s temperature, and may think it needs to work harder to bring it back to temp–even though it’s already there! Luckily there is an easy way to tell if this is the case.
Simply take a second thermometer and get an accurate reading of your building’s temperature. If the temperature is where you set your system for but it is still running, you have likely found the culprit. If this is the case, an HVAC specialist can come and replace your thermostat–a much simpler fix than what could happen if it is left to constantly run.
2. Dirty or Improper Filters
Air filters play a crucial role in your business’s HVAC system. They ensure that everyone in your building has clean and healthy air to breath by filtering out dust, pollen, bacteria, and other particles. While this is important and a big part of keeping your employees and customers safe, your filters can also make your HVAC system run inefficiently.
If your filters haven’t been replaced in a while, they can be clogged with all of the nasty things they have blocked out for you. This means that more air has to get through your system, making it have to work harder than usual. Another consideration is the type of air filter you have. If the filter is too fine for your system it can also block airflow, making the system have to push more air out and not shut off when it normally would. To solve this problem, make sure that your system is receiving proactive maintenance from HVAC professionals.
3. Dirty Coils
Evaporator and condenser coils are essential to the effective transfer of heat in your commercial HVAC system. Dirt, dust, and grime buildup over time can have a major effect on these coils’ function. Because dirty coils restrict proper heat exchange, your system struggles to maintain the right temperature and runs longer than it should.
Reduced cooling or heating efficiency is a blatant indicator of your coils being unclean. The coils may be the problem if your system appears to be operating constantly but isn’t successfully regulating the temperature. As part of a proactive maintenance program, routine coil cleaning can help keep your HVAC system functioning well and save expensive malfunctions.
4. Undersized System
If your business HVAC system never seems to turn off, it might not be large enough for your facility. An undersized unit must put in more effort to reach your facility’s heating or cooling needs, which can result in unnecessary wear and tear, increased energy costs, and even system failure.
