Why Does My Heat Pump Keep Turning On and Off?

If your heat pump in Alpharetta, GA is constantly turning on and off, you may wonder what is wrong with it. There can be several reasons for this, but some are more common than others. Here are four common reasons why your heat pump may be turning on and off constantly.

1. The Thermostat Is Set Too Low

If the thermostat is set lower than the room’s temperature, the heat pump will keep turning on and off to reach the desired temperature. To fix this, adjust the thermostat to a higher temperature. However, ensure you don’t set it too high, as this can cause the heat pump to overwork itself and break down.

2. Dirty Filters

If the filters are dirty, they can restrict airflow to the heat pump. This will cause the heat pump to work harder than necessary, causing it to turn on and off more frequently. If your heat pump has clogged filters, clean or replace them as soon as possible.

3. Low Refrigerant Levels

If the refrigerant levels in your heat pump are low, it can cause the unit to cycle on and off more frequently. The low refrigerant levels make it harder for the heat pump to maintain the desired temperature. If you suspect your heat pump’s refrigerant levels are low, get a professional to check it as soon as possible and refill it.

4. Oversized Unit

Heat pumps come in various sizes desired for the specific home. However, sometimes a heat pump is too big or small for the home.

If your heat pump is too big, it will turn on, achieve the desired temperature quickly and turn back off. As the temperature in the home starts to drop again, it will turn back on, causing it to cycle on and off more frequently than necessary.

If you need to carry out maintenance of your heat pump to prevent it from short-cycling, contact Comfort Atlanta Heating & Air for assistance. We offer a wide range of HVAC services to keep your heat pump running all winter long.
