What Ice on Your Air Conditioning Means

If you notice ice developing along the indoor coil of your air conditioner, you might at first think, “Well, that’s probably normal. The AC needs to get cold in order to send out chilled air.” However, air conditioners don’t actually work that way (they don’t generate cold; they remove heat). Ice appearing along the coil is a sign of a serious problem with the system that has caused it to lose its ability to absorb heat from the indoors. Unless you call for professional repairs as soon as possible, your air conditioner will start losing its ability to cool your house—and it might even break down.

A professional technician must handle the repair worked needed to stop ice developing on an AC. You can’t simply scrape the ice off or try to defrost it with hot water or a hairdryer: the ice will return. Call Avis Plumbing, Heating and Air for professional air conditioner repair service in Riverside, CA and stop your air conditioner from freezing over. We have more than six decades of experience handling all types of air conditioning malfunctions.

Why Ice Forms On an Air Conditioner

There are three main reasons for the formation of ice along an AC: a clogged air filter, dirt across the evaporator coils, or a loss of refrigerant.

If the air filter of an AC becomes clogged, it will cut down on airflow into the system. Insufficient warm air brought into the indoor cabinet means the evaporator coil will not be able to absorb enough heat, and this will cause moisture along the coil to freeze. You should change the air filter once a month to prevent this from happening. Once it starts, you need to call in a repair technician.

Dirt and grime build-up along the coil (which can also occur because of a clogged filter) will block heat absorption and lead to the coil freezing. A technician must remove the dirty coil in order to clean it.

Loss of refrigerant in the AC is the most serious problem that can cause air conditioner freeze. Although it seems contradictory that losing refrigerant would create ice, the problem is that a reduction in refrigerant means the coil will not be able to absorb sufficient heat to cool down the remaining refrigerant. This is similar to the other problems, but with the added trouble of the refrigerant loss causing damage to other parts of the system, particularly the compressor, which might overheat and fail. A technician must locate and seal the leak and then recharge the refrigerant to its proper level, as well as check for any other damage the loss may have caused.
