Common Issues


HVAC systems operate with refrigerant in a closed-loop system. In theory, the amount of refrigerant in the system should remain constant for the life of the system. If, however, a leak develops somewhere in the refrigerant loop, refrigerant will be lost and the system will transfer heat less effectively. Finding the leak, repairing the leak, and replacing lost refrigerant is necessary to bring the system back to its full operating potential.


Capacitors give motors a power boost to help them get moving. HVAC systems have several capacitors and each can potentially fail. A failed capacitor will prevent a motor from starting and all of a system’s motors must run for the cooling or heating to function properly.



HVAC systems use electric circuitry to control their various functions. While the simplest systems can only turn on and off, contemporary systems often have multiple-speed blowers, reversing valves for heat pumps, dehumidification functions, emergency heating elements, and more. Bad circuitry can completely disable a system and a circuit board replacement can be necessary to get the system working again.


HVAC systems have a few motors, at least one to run the compressor, one to run the outdoor fan, and another to run the indoor blower. If any of these motors malfunction the system will not operate properly.


All HVAC systems have drain lines that remove condensate produced by the evaporator coil. These lines can clog and humidity increases in the home. If not quickly addressed, water can seep into the home and cause damage. Mold and algae can also grow and cause musty odors.

Duct System

An HVAC system should distribute heating & cooling evenly throughout a house. If it’s not the duct system is likely damaged or poorly designed.
