Why Won’t My Heat Pump in Norton, VA, Stay On?

If you notice the heat pump in your Norton, VA home shuts off prematurely or short cycles, an underlying issue likely exists. It’s important to identify the causes of short cycling to prevent long-term damage. Here are some possible reasons your heat pump won’t stay on:

Thermostat Issues

Thermostats can cause various problems with your heat pump. If you haven’t properly calibrated your thermostat, you didn’t connect it correctly or it’s reading the temperature inaccurately, your system may short cycle and shut off prematurely.

Outdated thermostats require replacement models with upgraded technology to prevent constant breakdowns, especially if the issue is thermostat-related. Refer to your thermostat’s official manual or manufacturer’s guide to determine if your thermostat isn’t working, needs recalibration or is simply outdated for your existing HVAC system.

Dirty or Clogged Air Filter

Dirty or clogged air filters significantly contribute to the short cycling of heat pumps. When airflow becomes too restricted, your system may overload, making it hard to cool or heat your home. This can lead to short cycling issues, which will require heating repair experts to resolve.

Low Refrigerant Levels

If your heat pump has low refrigerant levels or a refrigerant leak, it may begin to short cycle. A lack of refrigerant hampers your system’s ability to complete a heating cycle, causing it to shut off prematurely and run inefficiently.

If your system has a refrigerant leak, you may hear hissing sounds from the area where the fluid is leaking. Take note of the sounds to determine if a refrigerant leak is a possibility.

Now you understand some possible reasons your home’s heat pump in Norton, VA, may short cycle and shut off prematurely. If you experience short cycling with your heat pump and need inspection, maintenance or repair services, contact Mid Mountain Heating & Cooling to schedule an appointment today.
