There's a misconception that commercial HVAC systems are just larger and more robust versions of residential systems. But the truth is that many HVAC systems are tailored specifically for their intended use and that they require consistent maintenance as well as repairs when required by commercial HVAC repair specialists in order to keep the machine functioning and the business running. Despite the wide variety of systems, there are similar problems that affect commercial HVAC systems. Here are five common repair problems that often arise with commercial systems.
Filters are absolutely essential for proper HVAC function in both residential and commercial applications. It's such a simple maintenance task that its importance is often downplayed. But a dirty filter can cause a domino effect with other essential systems. It's absolutely vital that filters are swapped out regularly so that the system has proper airflow. Dirty filters can lead to overheating, unnecessary wear and tear, and frozen evaporator coils.
Dirty Condenser Coils
Another vital HVAC maintenance task also deals with dirt buildup. Dirty condenser coils can also cause a domino effect of issues if the problem is not addressed. Dirty coils will reduce efficiency and also cause unnecessary wear and tear on the system.
Refrigerant is a liquid chemical for use in air conditioning systems, heat pumps, and refrigeration. Refrigerant leaks will affect the efficiency of the system, causing it to struggle to provide adequate air conditioning. Symptoms of refrigerant leaks include ice on coils, humid indoor air, and popping and hissing sounds. If the problem isn't addressed, it can lead to significant damage to the compressor.
Blower Motor Running
Another common repair that commercial HVAC technicians have to deal with is addressing a blower motor that won't stop running even when the thermostat settings should be triggering it to turn off. When this happens, a fan could be stuck because of a bad fan limit switch. It could also be caused by blocked airflow.
Problems like the one listed above can cascade into other issues such as tripped breakers and blown fuses because the blower motor won't stop running and overloads the system. If a breaker continues to trip after being turned back on, there is something else at work that needs to be addressed by a commercial HVAC repair specialist. Blown fuses can be a sign that it has ceased to protect the unit from overheating. Electrical issues are often signs of bigger issues.
