The summer can get so hot in Lincoln, so how in the world is your air conditioner freezing over? It seems to make no sense. You may not even realize it’s happening. How will you know if your air conditioner is frozen? It may seem like a crazy question, but you typically won’t actually see the ice except in extreme cases. Here are symptoms to look for that indicate you could be dealing with a frozen AC system that could be in need of air conditioning service:
- Warm air is coming out of your registers while the air conditioner is running.
- Water is leaking from or collecting under your air conditioner.
When we say your air conditioner is frozen, what’s actually frozen is the evaporator coil, which moves heat out of your home to sustain the cool temps. There are two main reasons that an evaporator coil may freeze; one is a refrigerant leak and the other is a blockage of airflow.
If your air conditioner has a refrigerant leak, you will want to discuss with your AW Heating & Air Conditioning technician during your air conditioning service appointment to understand if you will benefit more from repairing or replacing your air conditioner. We can help you evaluate the pros and cons using information such as the age of your air conditioner and its service history, along with other things.
If your air conditioner has frozen as a result of an airflow blockage, it’s because there is a lack of air passing over the evaporator coil to dry the condensation that develops on it—then it freezes. Air flow blockages are regularly caused by dirty air filters or even dirty cooling fins. These problems can be remedied (and avoided!) by a routine air conditioner service appointment. At these service sessions, your technician will clean your system, replace your air filters and confirm everything is operating as it should with no potential issues on the horizon. It’s also a good idea to mark your calendar or set a reminder on your phone to check your air filters regularly and change the filters when they are dirty. Always be sure that furniture, curtains and other household items aren’t blocking your registers, as even this could cause a serious airflow problem and the ensuing freezing problems.
