Heat pump problems and failures are not uncommon during the winter months. With temperatures outside dropping, extreme fluctuations in weather conditions and all the extra use, it’s not surprising for a heat pump to run into a few operating issues. As your local heating contractor in Tuscaloosa, AL, one of the most common problems we see during the winter is a frozen heat pump.
Your heat pump pulls heat from the air or ground outside and transfers it into your home. Air from the outside of your home is pulled into the unit over coils that contain liquid refrigerant. The liquid in the coils absorbs the heat in the air and creates a hot vapor. The vapor then goes through a compressor, which increases its pressure and temperature, and is then pumped into your air ducts and distributed throughout your home.
If your heat pump is frozen, there may be several contributing factors. Some problems you can rectify on your own, while others will require calling in a professional heating contractor in Tuscaloosa, AL. To help you determine what’s causing your heat pump to freeze up, here are a few troubleshooting tips:
- Change the filter: A dirty or clogged filter may be obstructing the airflow to your system. You should be changing the air filter regularly to avoid this problem. However, even if you changed it recently, frequent use during the winter months may have caused it to become saturated more quickly than usual. If your heat pump is frozen, checking the air filter is always a good place to start.
- Check the airflow: Ice can build up on the coils for your heat pump if the airflow is restricted. Outdoor debris such as branches, grass, leaves and even snow can accumulate underneath and around your condenser. Meanwhile, indoors, furniture, carpeting and even closed doors may be obstructing the airflow. To keep your heat pump from freezing, check to make sure the area around your unit and all the air ducts are free from debris.
- Make sure your unit is level: Over time, the foundation your unit is on can shift, which may cause your unit to sit unevenly. If your unit is sitting unevenly, water may not drain away from your unit properly. The water can actually accumulate in your condensing system, causing your heat pump to freeze.
- Call in a professional: If your heat pump is frozen, it may be a problem with the mechanical integrity of your system. A broken fan, faulty valve or some other issue may be contributing to the problem. In these cases, it is best to call in a professional rather than risk ruining your whole system.
