Whether enduring the heat of summer or winter freeze in Maryville, TN, it’s frustrating to deal with a heat pump that continually turns on and off. There are some common reasons your system is shutting off and turning on unexpectedly. Read on to learn more about them and what to do if your heat pump keeps cycling constantly.
Erroneous Reading on the Thermostat
A thermostat can give an erroneous reading for several reasons. If the thermostat is in a location that experiences direct sunlight, drafts or other factors that can affect its accuracy, it’ll misread the temperature of your entire home. Alternatively, wiring issues and outdated technology can contribute to the problem.
A clogged filter is a simple problem, but it’s bad enough to cause your system to turn off unexpectedly. It’s inevitable that your filter will collect debris and dust over time. If your system can’t circulate the air efficiently, it has to work harder to heat and cool your home properly.
Oversized Heat Pump
An oversized system will cause an area to reach the set temperature quickly and then shut off. An oversized system that cycles on and off frequently isn’t only inefficient, but it can also cause unnecessary wear and tear on its components.
If you have a refrigerant leak, this causes the system to have issues with heat transfer. It could be due to regular wear and tear, improper installation or factory defects. In the event of a refrigerant leak, the pressure of the system lowers, triggering a low-pressure switch that shuts down the heat pump.
An error-prone thermostat, clogged filter, oversized system or refrigerant leakage can cause your heat pump to keep turning on and off. Consult our HVAC experts at LB Chase Mechanical to schedule heat pump repairs.
