Why Does Your Air Conditioner Freeze in Summer?

The summer can get very hot in Opelika, 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 ridiculous 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 need air conditioning service:

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

When we say the 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 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 talk with your Farnell Mechanical, 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 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 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 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 challenges 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 frequently 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 significant airflow problem and the ensuing freezing problems.

If your air conditioner freezes, turn it off using your thermostat and call the experts at Farnell Mechanical, Inc. to schedule an air conditioning service appointment.
