Why Does Your Air Conditioner Freeze in Summer?07/20/2017The summer can get very hot in Zelienople, 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 happening. How will you notice 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 be dealing with a frozen AC system that could need air conditioning service: Warm air is coming out of your registers while the air conditioner is on.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 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 talk with your Knoechel Heating Company 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 evaluate the pros and cons using facts such as the age of your air conditioner and its service history, among other things. If your air conditioner has frozen as a result of an airflow blockage, it’s because there is a lack of 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 remedied (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 running 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 regularly 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 large airflow problem and the subsequent freezing problems.
