Why Does Your Air Conditioner Freeze in Summer?

The summer can get very hot in Middletown, so how in the world is your home’s 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 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 gathering under your air conditioner.

When we say your air conditioner is frozen, what’s actually frozen is the evaporator coil, which moves heat out of your home to maintain the cooler temperatures. 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 talk with your Schagrin Gas Company 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 facts such as the age of your air conditioner and its service history, along with other things.

If your air conditioner has frozen as a result of an airflow blockage, it’s because there is not enough air passing over the evaporator coil to dry the condensation that develops 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 ensure everything is running as it should with no potential challenges 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 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 serious airflow problem and the following freezing problems.

If your air conditioner freezes, turn it off using your thermostat and call the experts at Schagrin Gas Company to schedule an air conditioning service appointment.
