Why Does Your Air Conditioner Freeze in Summer?07/20/2017The summer can get extremely hot in Sylmar, 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 know if your air conditioner is frozen? It may seem like a ridiculous question, but you generally won’t actually see the ice except in extreme cases. Here are symptoms to monitor 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 the 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 reasons 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 talk with your American Premier Heating & Air Conditioning 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 evaluate the pros and cons using background such as the age of your air conditioner and its service history, among other things. If your air conditioner has frozen due to 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 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 confirm everything is running as it should with no potential issues on the horizon. It’s also a valuable 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 check that furniture, curtains and other household items aren’t blocking your registers, as even this could cause a serious airflow problem and the following freezing problems. If your air conditioner freezes, turn it off using your thermostat and call the pros at American Premier Heating & Air Conditioning to schedule an air conditioning service appointment.
