When Your AC Is Cold As Ice: Common Causes Of Icy Coils

Veronica Torres

If you're having trouble keeping your house cool despite the fact that you have central air, there may be a problem with the compressor. While problems such as leaves or debris around the compressor may be easy to fix, there are other things you should also watch for. One common cause of insufficient cooling is ice build-up inside the compressor. Here's a look at some of the common causes of ice accumulation and what you can do about them. 

Why Does Ice Matter?

The coil inside the air conditioning compressor is a key component of the central air's cooling ability. The refrigerant flowing through the coil chills it while the air passing over the coil absorbs just enough cold air to keep the coil's surface temperature above freezing. This allows the moisture in the air to simply drip to the collection tray below. If the system isn't functioning properly, the coil may get too cold and cause that moisture to freeze onto the coil before it can drip away.

The ice layer over the coil will insulate the coil, shielding it from the air and keeping it from drawing more moisture out or cooling it. Over time, this ice can actually crack the coil and cause the system to fail completely.

Fan Blockage

One common case of ice on the compressor is insufficient airflow. This often happens when something is blocking the fan inside the air conditioner. Remove the access panel on the condenser unit and check the fan for any signs of debris. Make sure that the fan is spinning properly when it is free of debris. If not, it may need to be replaced.

Low Refrigerant

It may seem odd that low levels of refrigerant could cause your air conditioner to freeze up, but it is true. The refrigerant flows through the coil system to keep the temperature regulated and transfer the cold to the air going into the house. When you're low on refrigerant, it can't draw the cold away from the coils as effectively, which causes them to freeze.

Since the refrigerant in an air conditioner is part of a closed system, it means that any low refrigerant levels are due to a leak. You'll need a licensed air conditioning technician to spot the source of the leak, repair it and recharge your system.

If you notice ice in your air conditioner or it isn't cooling effectively, either of these two things may be the cause. Talk with an air conditioning repair technician today to have the problem addressed.
