Defrost Cycle Timing

The defrost timer regulates how often your heat pump stops heating the inside of the home in order to clear its outside parts of any ice that may be forming. Although defrost cycles are necessary for the heat pump to operate at peak condition and efficiency, if the timer triggers the defrost cycles too often or for too long, you will notice adverse effects: a reduction in the heating of your home and increased heating costs due to the inefficiency of the system. Over time, an improperly calibrated defrost timer can shorten the compressor’s life.

Pledge: We time the heat pump’s defrost cycles to make sure they conform to specifications.
