Ice forming on your heat pump in Pooler, GA, can be alarming, especially when you consider that temperatures rarely get below freezing. However, most of the reasons for a frozen system are internal issues with the system. If there’s ice on your heat pump, consider the following possible reasons.
Dirty Air Filter
While your air filter’s primary purpose is to protect your home’s indoor air quality (IAQ), it also has a direct impact on how your system functions. When the filter has too much dirt and debris in it, air can’t pass through. This hinders airflow and traps moisture, which can result in your heat pump freezing up.
Incorrect Thermostat Setting
When temperatures reach their highest, it’s easy to assume that you should turn your thermostat down so your home gets even cooler. Ultimately, this leads to the system working too hard while also allowing your coil to freeze. The low heat load, which stems from the lower temperature, allows coils to freeze and ice to form on your heat pump.
Insufficient Refrigerant
Your HVAC system relies on a chemical called refrigerant to change the temperature of the air before pushing it into your home. The tiny tubes that transport this liquid can suffer damage, allowing it to leak. When your system doesn’t have enough refrigerant, it runs the risk of freezing up.
Faulty Defrost Cycle
In order to combat freezing, your system goes into a regular defrost cycle. However, if something goes wrong that prevents this cycle from starting or finishing its work, the system can freeze up.
