Why Does Your Air Conditioner Freeze in Summer?

The summer can get extremely hot in Mobile, so how in the world is the 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 crazy 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 dealing with a frozen AC system that could need air conditioning service:

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

When we say the air conditioner is frozen, what’s actually frozen is the evaporator coil, which transfers heat out of your home to keep it cool. 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 speak with your Farnell Heating & Air Conditioning Inc technician during your air conditioning service appointment to see 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, among other things.

If your air conditioner has frozen as a result 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 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 confirm 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 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 serious airflow problem and the ensuing freezing problems.

If your air conditioner freezes, turn it off using your thermostat and call the team at Farnell Heating & Air Conditioning Inc to schedule an air conditioning service appointment.
