It’s common for a heat pump to freeze up, even during hot summers in Cedartown, GA. Several things can cause a heat pump to do this. Let’s take a look at three of the most common explanations for your heat pump to start freezing up.
Heat Pump Refrigerant Issues
Refrigerant is a liquid or gas that helps the heat pump make things warm or cold. Your heat pump needs refrigerant to work correctly. If its supply of refrigerant is low, the evaporator coil might get too cold and freeze.
Low refrigerant levels usually mean there’s a leak. In that case, it’s important to let a professional HVAC service technician check the issue. Exposure to refrigerants can put your health at risk, so it’s not something to handle on your own.
You also can’t buy most types of heat pump refrigerants in Georgia without proper certification. To purchase it online or in stores, you’ll likely need certification from the Environmental Protection Agency. Leave this repair to the HVAC professionals.
Lack of Heat Pump Maintenance Causes Freezing Up
Failure to stay current with preventive maintenance can lead to problems with your heat pump freezing. Scheduling maintenance twice a year is usually enough to catch and prevent potential problems.
The best time for maintenance is generally once in the spring and again in the fall. This is most likely to keep things running smoothly during the cooling and heating cycles.
Dirty Evaporator Coil
Your heat pump’s refrigerant travels through the evaporator coil. That’s how the refrigerant is able to transport heat either in or out of your home.
If the evaporator coil is dirty, the refrigerant struggles to get the job done. As a result, thick ice might develop on the coil. If this is why your heat pump is freezing up, cleaning the coils should solve the problem.
An inspection by an HVAC service technician is the best way to figure out exactly why your heat pump is freezing. Call Merrell & Associates to discuss your heat pump repair needs.
