No homeowner in Mims, FL, wants to experience a heat pump malfunction during the wintertime. Your heat pump transfers heat from the outdoor air into your home. The colder the air temperature, the harder it is for your heat pump to do this. Read on to learn about three heat pump issues you could encounter this winter.

Blowing Cold Air

If your heat pump blows cold air for 10 to 15 minutes, this is just a defrost cycle. After the defrost cycle finishes, your heat pump should return to its heating functions. When the heat pump keeps blowing cold air, there could be a dirty coil or filter. An improper refrigerant level could also cause the heat pump to blow cold air, explains the Department of Energy.

Ice Buildup

A little frost on the outdoor unit of the heat pump is a normal part of its defrost cycle. A lot of ice or icicles are a problem. Thick ice buildup impedes airflow through the coil. The thick layers of ice impede the heat pump’s ability to absorb heat from the outdoor air and transfer it into your home. If a defrost cycle doesn’t get rid of the ice buildup, you’ll need expert HVAC services to diagnose the problem.

Constant or Frequent Cycling

On a cold day, your heat pump will cycle a lot. If it has a backup electric resistance heating unit, that may also be used for supplemental heat. However, the heat pump should cycle for a few minutes then stop. There should be a few minutes of rest. If it won’t turn off or turns back on just a few seconds after ending a heating cycle, there could be an issue with the thermostat, thermocouple, or refrigerant. You could also have a dirty air filter.
