Why Does Your Air Conditioner Freeze in Summer?07/20/2017The summer can get very hot in Erie, 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 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 look for that indicate you could be dealing with a frozen AC system that could require air conditioning service: Warm air is coming out of your registers while the air conditioner is on.Water is leaking from or pooling under your air conditioner. When we say your air conditioner is frozen, what’s actually frozen is the evaporator coil, which transfers 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 other reason is a blockage of airflow. If your air conditioner has a refrigerant leak, you will want to talk with your Patterson & Stirling Inc 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 weigh 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 isn’t sufficient air passing over the evaporator coil to dry the condensation that acquires 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 challenges 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 significant airflow problem and the subsequent freezing problems. If your air conditioner freezes, turn it off using your thermostat and call the pros at Patterson & Stirling Inc to schedule an air conditioning service appointment.
