Federal Department of Energy came up with a few common problems with air conditioning units along with how you can troubleshoot them.
- Refrigerant leaks– Air conditioning units work efficiently when the refrigerant charges matches the specifications of the manufacturer. In order to fix those leaks, you will need to hire a trained technician.
- Inadequate maintenance– Dirty air conditioning coils and filters can cause unit malfunction. Make sure that you clean the filters and coils regularly.
- Electrical control failure– Fan controls and compressors of your air conditioning unit can wear out. Have a trained technician check the electrical connections during a service call.
- Sensor problems– Check your sensor if it is knocked out of position. If it is far from the coil, carefully bend the wire that holds it in place.
