Heat pumps are known for their innovative, energy-efficient designs and functioning. However, they can develop problems that cause them to short cycle. Learn about some of the common reasons why your heat pump in Allison Park, PA switches on and off so much.
Thermostat Issues
A poorly placed or malfunctioning thermostat will cause an HVAC system to short cycle. It may also misread the temperature in the room if it is near a heat source or draft. If your heat pump turns on and off a lot, you may need a professional to move, repair or recalibrate the thermostat.
Clogged Air Filters
When debris clogs the air filters, it restricts airflow and causes your heat pump to freeze up or overheat. When the system gets too hot or freezes, it triggers its safety mechanisms to prematurely turn off the unit. Clean or change the air filters every one to three months to decrease the risk of short cycling.
Low Refrigerant
When there isn’t enough refrigerant in the heat pump, it will turn itself on and off repeatedly in an effort to heat or cool your home. Without this coolant, the coils can’t absorb heat, causing condensation on them to freeze. Schedule yearly tune-ups for your HVAC system to ensure it has enough refrigerant.
Malfunctioning Electrical Components
When electrical components in your heating and cooling system malfunction, they can cause it to turn on and off repeatedly. Problems with the parts cause issues like faulty relays, sensor issues and control board malfunctioning. They also require professional HVAC repairs.
Oversized Heat Pump
A heat pump that is too powerful for your house’s size will cool or heat some spaces too quickly and shut itself off before it finishes its cools the whole home. This issue causes the HVAC system to use too much energy and raises your heating and cooling bills. It can also increase the humidity inside your home, and leaves some spaces too warm.
