Why Does Your Air Conditioner Freeze in Summer?07/20/2017The summer can get very hot in Colfax, so how in the world is your air conditioner freezing over? It seems to make no sense. You may not even realize it’s happening. 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 watch for that indicate you could have a frozen AC system that could be in need of air conditioning service: Warm air is coming out of your registers while the air conditioner is on.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 causes 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 Ackerman Heating & Air Conditioning 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 information 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 isn’t sufficient air passing over the evaporator coil to dry the condensation that builds up on it—then it freezes. Air flow blockages are regularly caused by dirty air filters or even dirty cooling fins. These problems can be alleviated (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 working 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 the filters when they are dirty. Always be sure 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.
