Why Does Your Air Conditioner Freeze in Summer?

The summer can get so hot in Abilene, 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 notice if your air conditioner is frozen? It may seem like a crazy question, but you generally won’t actually see the ice except in extreme cases. Here are symptoms to look for that indicate you could be working 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 gathering under your air conditioner.

When we say your home’s air conditioner is frozen, what’s actually frozen is the evaporator coil, which transfers heat out of your home to keep it cool. There are two main explanations that an evaporator coil may freeze; one is a refrigerant leak and the second is a blockage of airflow.

If your air conditioner has a refrigerant leak, you will want to discuss with your Abilene Air-Tech Inc 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 weigh the pros and cons using background such as the age of your air conditioner and its service history, as well as other things.

If your air conditioner has frozen because of an airflow blockage, it’s because there is not enough air passing over the evaporator coil to dry the condensation that builds up on it—then it freezes. Air flow blockages are commonly 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 working as it should with no potential challenges on the horizon. It’s also a great 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 make sure that furniture, curtains and other household items aren’t blocking your registers, as even this could cause a serious airflow problem and the subsequent freezing problems.
