The summer can get very hot in New Castle, 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 notice if your air conditioner is frozen? It may seem like a silly question, but you typically 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 need air conditioning service:
- Warm air is coming out of your registers while the air conditioner is running.
- 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 speak with your Central Heating & Plumbing 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 information such as the age of your air conditioner and its service history, as well as other things.
If your air conditioner has frozen due to an airflow blockage, it’s because there is not enough air passing over the evaporator coil to dry the condensation that acquires 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 confirm everything is working as it should with no potential challenges 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 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 ensuing freezing problems.
