Why Does Your Air Conditioner Freeze in Summer?07/20/2017The summer can get very hot in Saint Peters, so how in the world is the air conditioner freezing over? It seems to make no sense. You may not even realize it’s taking place. How will you know if your air conditioner is frozen? It may seem like a crazy question, but you generally won’t actually see the ice except in extreme cases. Here are symptoms to watch for that indicate you could be working with 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 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 explanations that an evaporator coil may freeze; one is a refrigerant leak and the second is a blockage of airflow. If your air conditioner has a refrigerant leak, you will want to speak with your C-N-O Comfort Zone 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 weigh 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 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 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 make sure everything is operating as it should with no potential issues 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 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 large airflow problem and the ensuing freezing problems.
