Why Does Your Air Conditioner Freeze in Summer?07/20/2017The summer can get extremely hot in Port Saint Lucie, 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 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 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 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 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 Custom Air Systems Inc 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 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 because of an airflow blockage, it’s because there is a lack of air passing over the evaporator coil to dry the condensation that builds up on it—then it freezes. Air flow blockages are commonly 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 operating as it should with no potential problems 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 frequently 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 large airflow problem and the subsequent freezing problems.
