Why Does Your Air Conditioner Freeze in Summer?

The summer can get extremely hot in Tomball, so how in the world is the air conditioner freezing over? It seems to make no sense. You may not even realize it’s occurring. How will you determine if your air conditioner is frozen? It may seem like a silly question, but you typically won’t actually see the ice except in extreme cases. Here are symptoms to monitor for that indicate you could be dealing with a frozen AC system that could need 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 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 other is a blockage of airflow.

If your air conditioner has a refrigerant leak, you will want to discuss with your Premium Air Services LLC technician during your air conditioning service appointment to see 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, among other things.

If your air conditioner has frozen due to an airflow blockage, it’s because there isn’t sufficient 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 fixed (and avoided!) by a routine air conditioner service appointment. At these service sessions, your technician will clean your system, replace your air filters and ensure everything is running as it should with no potential problems 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 often and change your air 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 significant airflow problem and the subsequent freezing problems.
