You depend on the heat pump in your Clinton, MS, home to keep you comfortable year-round. So, when your system won’t stay on, it’s a major concern. Here are some reasons a heat pump could short cycle or fail to stay on:
Dirty Air Filter
If the air filter in your heat pump gets too dirty, it’ll restrict airflow through the system. That can cause your system to turn on and off frequently as it tries to maintain your home’s temperature. Replacing the dirty air filter should restore your system to regular operation.
Thermostat Malfunction
Multiple thermostat problems could prevent your heat pump from staying on. For example, if your thermostat fails to detect the temperature correctly, it could turn off your system prematurely. A damaged thermostat wire might cause the same issue.
Refrigerant Loss
Your heat pump requires a specific refrigerant charge to function. If your system leaks refrigerant, it may fail to turn on or stay on. Low refrigerant can also lead to a frozen evaporator coil and frequent shutoffs.
If you suspect a refrigerant leak, don’t ignore it. Running your system with low refrigerant can damage it. Our HVAC service technicians can recharge your heat pump’s refrigerant during an HVAC maintenance visit.
Oversized Heat Pump
If your system is too large for your house, it may turn off more frequently than expected. It’s a result of the oversized system reaching your set temperature too fast. An undersized system may short cycle as it struggles to maintain your home’s temperature.
Faulty Control Board
Finally, your heat pump’s control board could malfunction and prevent your system from remaining on. If the board misinterprets signals from your thermostat, it may turn off the system. Or the board might sense a nonexistent fault and trigger a shutdown.
If you’re struggling to get your heat pump to stay on, you need an expert HVAC service technician to investigate. Call our team at Modern Air to schedule a repair appointment right away.
