Why Does Your Air Conditioner Freeze in Summer?

The summer can get so hot in Reeds Spring, 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 occurring. How will you determine if your air conditioner is frozen? It may seem like a silly 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 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 transports heat out of your home to maintain the cooler temperatures. 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 discuss with your All Seasons Comfort Systems 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 facts such as the age of your air conditioner and its service history, along with 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 acquires 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 ensure everything is running as it should with no potential issues on the horizon. It’s also a good 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 check 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 team at All Seasons Comfort Systems Inc to schedule an air conditioning service appointment.
