Why Does Your Air Conditioner Freeze in Summer?

The summer can get so hot in Brandon, so how in the world is the air conditioner freezing over? It seems to make no sense. You may not even realize it’s taking place. How will you notice if your air conditioner is frozen? It may seem like a silly question, but you generally won’t actually see the ice except in extreme cases. Here are symptoms to watch for that indicate you could be dealing with a frozen AC system that could require air conditioning service:

  • Warm air is coming out of your registers while the air conditioner is operating.
  • Water is leaking from or pooling under your air conditioner.

When we say your air conditioner is frozen, what’s actually frozen is the evaporator coil, which transports heat out of your home to maintain the cooler temperatures. 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 talk with your Brandon Heating and Plumbing (1998) Ltd. technician during your air conditioning service appointment to determine if you will benefit more from repairing or replacing your air conditioner. We can help you weigh the pros and cons using facts such as the age of your air conditioner and its service history, as well as 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 acquires on it—then it freezes. Air flow blockages are frequently 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 make sure everything is working as it should with no potential problems on the horizon. It’s also a valuable idea to mark your calendar or set a reminder on your phone to check your air filters often and change them 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 significant airflow problem and the following freezing problems.
