Why Does Your Air Conditioner Freeze in Summer?

The summer can get extremely hot in Branchville, 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 ridiculous 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 operating.
  • 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 transports heat out of your home to keep it cool. There are two main reasons 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 Willco Air Conditioning, Refrigeration & Heating 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 assess the pros and cons using background such as the age of your air conditioner and its service history, along with 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 acquires on it—then it freezes. Air flow blockages are regularly 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 issues 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 often and change your air 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 large airflow problem and the subsequent freezing problems.

If your air conditioner freezes, turn it off using your thermostat and call the experts at Willco Air Conditioning, Refrigeration & Heating Inc. to schedule an air conditioning service appointment. We’ll help you identify the problem and have your home back to cool and comfortable quickly. Call us at 862-345-6896 or arrange an appointment with us online.
