Why does my evaporator coil freeze?
There are two primary things that can cause your evaporator coil to freeze. The first is a lack of airflow across the coil in general. Remember that there is refrigerant flowing through the copper or steel tubing that is designed to remove the humidity from your home. If there is no humidity to remove, or even if airflow is blocked for some reason, ice will begin to develop. Second, your coil can freeze if there is a problem in the refrigeration system itself. Air conditioning units with a low level of refrigerant can freeze, and if this is the case, your unit will need servicing.
How to defrost a coil?

You should never be tempted to use a blow dryer or a heating pad as this will cause the ice to melt far too quickly.
What is the Evaporator Coil?
The air conditioning coil , which is called the evaporator coil, is essentially the most important part of your unit. It is constructed of aluminum fins bonded to internally grooved aluminum tubing. As the warm air in your home passes over these coils, the heat is removed from the air and cooler air is filtered into your home via the system. The evaporator coil works directly alongside the condenser; the evaporator coil removes the humidity from the air and the condenser condenses this humidity into water for elimination.
Why is my air conditioner not working?
As a homeowner, it is likely that you don’t notice a problem with your air conditioning system until it runs continuously or not at all, the air in your home is too warm , or the airflow coming through your vents is significantly reduced.

What is an evaporator coil?
The evaporator coil of your air conditioner is one of the primary components in the heat exchange process, which allows your system to heat and cool your home. As your AC unit pulls in the warm air from your home, it passes this air over the evaporator coils. The coils contain liquid refrigerant that turns into gas once it interacts with warm air particles. This process works to quickly cool the air, which the blower fan then sends throughout your home. In simpler terms, the coils hold the cold refrigerant and remove the heat from the air as it passes over them. For heating, the process is essentially reversed, creating heat from the air and pushing it into your home instead of removing it.
