Generally, a heat pump should run for no longer than 10 to 15 minutes at a time. Sometimes, though, heat pumps run continuously because they’re malfunctioning or oversized. Read on to learn why your heat pump in Mount Pleasant, SC, won’t stop running.

Dirty, Dusty Coils

The evaporator coil in your air handler, the indoor unit, may turn out to be the culprit. When it gets covered in dust and dirt, this coil can struggle to absorb heat from your home. As a result, the heat pump will never really attain the temperature you’ve set.

Check the compressor outside, too, because the condenser coil, if dirty and grimy, will fail to release the heat that the air handler gathered from your home. This leads to the same result.

Refrigerant Leak

Refrigerant refers to the chemical that cycles through the heat pump and transfers the heat from inside to outside in cooling mode. If you’re low on refrigerant because of a leak in the refrigerant line, the air doesn’t get cool enough to satisfy your thermostat. As a result, the problem forces the heat pump to run for a longer period, if it turns off at all.

Undersized Heat Pump

Cleaning the coils forms part of any good maintenance plan, whereas repairing a refrigerant leak requires more expertise and careful attention. If you’ve exhausted all your other options, the culprit might be because of your heat pump’s size. Sizing your system for your home is vital during installation.
