Why Does Your Air Conditioner Freeze in Summer?

The summer can get so hot in Grove City, so how in the world is your 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 generally won’t actually see the ice except in extreme cases. Here are symptoms to monitor for that indicate you could have a frozen AC system that could require 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 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 other reason is a blockage of airflow.

If your air conditioner has a refrigerant leak, you will want to discuss with your Air Quality Solutions 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 evaluate the pros and cons using information 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 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 frequently 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 make sure everything is running as it should with no potential issues 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 your air filters when they are dirty. Always check that furniture, curtains and other household items aren’t blocking your registers, as even this could cause a large airflow problem and the following freezing problems.

If your air conditioner freezes, turn it off using your thermostat and call the experts at Air Quality Solutions to schedule an air conditioning service appointment.
