Why Does Your Air Conditioner Freeze in Summer?

The summer can get so hot in Tuscaloosa, 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 taking place. How will you notice if your air conditioner is frozen? It may seem like a ridiculous question, but you usually 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 require air conditioning service:

  • Warm air is coming out of your registers while the air conditioner is on.
  • 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 sustain the cool temps. 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 speak with your KDM Service Corporation 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 assess 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 because of an airflow blockage, it’s because there is a lack of air passing over the evaporator coil to dry the condensation that develops 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 great idea to mark your calendar or set a reminder on your phone to check your air filters regularly and change them when they are dirty. Always check that furniture, curtains and other household items aren’t blocking your registers, as even this could cause a significant airflow problem and the subsequent freezing problems.

If your air conditioner freezes, turn it off using your thermostat and call the pros at KDM Service Corporation to schedule an air conditioning service appointment. We’ll help you identify the problem and have your home back to cool and comfortable in no time. Call us at 205-758-2703 or arrange an appointment with us online.
