Why Is There Ice on My AC?

Even though we are at the hottest point of the summer, there are certain things you should definitely not be seeing from your whole home air conditioning system. One of these is ice build-up. While it may seem, initially, like it could be a normal development with your AC, it isn’t. More importantly, it is an indication that there is a problem with your air conditioner that needs to be fixed. The AC pros at Celco Heating and Air Conditioning can determine why there is ice on your air conditioner and repair it so that you can enjoy the rest of your summer in Fairfield, CT in cool, dry air.

Reasons for Ice Build-Up

There are typically three main causes for ice to develop on your air conditioner:

One, or both, of the fans aren’t working correctly.

There are two fans in your air conditioning system, and they both help significantly with air flow. If one (or both) of these fans slows down or stops, the air flow in your system will, too. Your system needs a certain amount of air flow in order to release heat and cool, and a broken fan or fans will create an imbalance that can result in ice development.

Your system’s air filter is clogged.

The air filter in your system captures large particles of dirt and dust. It doesn’t take long for the filter media to become saturated with these kinds of particles, which is why it is strongly recommended that you change your air filter every 3 months. A clogged air filter can significantly interfere with proper air flow, leading to the potential for icing.

There’s a refrigerant leak in your system.

The refrigerant in your system facilitates the heat transfer process that is necessary in order to cool your home. Every air conditioner needs a specific amount of refrigerant to operate as dictated by the AC’s manufacturer. If your system develops a leak, the level of refrigerant will be reduced, creating an imbalance in the heat release/cooling process.
