3 Causes of Heat Pump Short Cycling

contentImage

Many homeowners use heat pumps for indoor heating and cooling because these appliances are energy-efficient and require minimal maintenance. While pumps should last around 15 years, you may need to schedule repairs if your system turns on and off frequently. Here are a few malfunctions that lead to this problem.

Why Do Heat Pumps Short Cycle?

1. Airflow Obstructions

Ductwork moves air throughout a building and creates consistent temperatures. If these ducts are clogged with dust, dirt, pollen, or other contaminants, the appliance can experience performance issues.

To promote proper airflow, change the filters every two months. Get the ductwork cleaned yearly to improve indoor air quality and prevent overheating.

2. Low Refrigerant Levels

Refrigerant travels through a compressor to move humidity and heat outdoors. Damaged compressors can leak refrigerant, causing the pump to work harder to maintain indoor temperatures.

HVAC systems may also experience corrosion if pets repeatedly urinate on them. Check if the outdoor component of the heat pump has ice accumulation in the coils, as this is often a sign there is a refrigerant leak that requires professional attention.

3. Thermostat Issues

If the thermostat is too close to a heat source, like the kitchen or a sunny window, it may take incorrect readings. If the unit perceives the interior temperature to be higher than it is, it may constantly cycle to try and bring it down.

An HVAC technician will determine whether you should have the thermostat moved. They may also recalibrate the unit or install a smart control to improve heat pump efficiency when scheduling heating and cooling.
