Is it normal for ice to form on air conditioner?

What causes an AC unit to freeze up?
There are many reasons why your AC unit may be freezing up. … A freeze up can also be caused by low refrigerant and improper fan operation.

Can I use a hair dryer to defrost my AC?
Try a Little Heat If just a little ice has formed on your evaporator coil, you can defrost it faster using a hair dryer turned on to the lowest setting. Hold the hair dryer at least 12 inches from the coil. Too much heat can crack an evaporator coil, so use caution if you decide to go this route.
Can a dirty filter cause AC to freeze up?
As a result of the buildup, a dirty filter will also cause poor cold airflow in your air conditioning system. That cold air will be trapped inside your air conditioner, causing ice to form on its coils. Once that happens, your air conditioner will freeze up and become inoperable.
