Reasons Your Heat Pump Never Turns Off

If you’re like most homeowners in Marietta, GA, you probably don’t think about your HVAC system until it stops working. Heat pumps should cycle on and off no more than four times per hour. Here are the reasons your heat pump never turns off:

Faulty Thermostat

If the thermostat isn’t working properly, it’s likely not sending the correct signal to the heat pump telling it to turn off. As a result, the system will keep running even when it’s not needed.

Dirty Air Filter

A dirty air filter can block airflow and cause the heat pump to overheat, reducing indoor air quality. When this happens, the system will keep running to cool down.

Frozen Evaporator Coil

If the evaporator coil freezes, it can prevent the heat pump from turning off. The frozen coil will cause the system to run longer in an attempt to defrost the coil. Ensure you keep the evaporator coil clean to prevent this from happening.

Refrigerant Leak

A refrigerant leak can also cause the heat pump to run constantly. When there’s a leak, the system can’t maintain the correct pressure, so the compressor has to work harder to cool the air. As a result, the system will keep running even when it’s not needed.

Incorrectly Sized System

The size of your system should match the size of your home. If the system is too small for the space, it’s trying to heat or cool and will have to run longer to achieve the desired temperature. This can cause the system to run constantly and never turn off.

The best way to prevent your heat pump from running constantly is to service it regularly by a qualified HVAC service technician. Contact Innovative Mechanical LLC today to schedule maintenance of your system. We’ll clean the coils, check for leaks and ensure the system runs properly.
