Why Does Your Air Conditioner Freeze in Summer?07/20/2017The summer can get so hot in Rocky Mount, so how in the world is your 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 silly question, but you usually won’t actually see the ice except in extreme cases. Here are symptoms to monitor for that indicate you could have 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 gathering 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 second is a blockage of airflow. If your air conditioner has a refrigerant leak, you will want to speak with your Davis 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 facts such as the age of your air conditioner and its service history, as well as other things. If your air conditioner has frozen as a result of an airflow blockage, it’s because there is not enough air passing over the evaporator coil to dry the condensation that develops 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 running as it should with no potential problems 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 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 significant airflow problem and the ensuing freezing problems. If your air conditioner freezes, turn it off using your thermostat and call the experts at Davis Heating & Air Conditioning to schedule an air conditioning service appointment.
