Over the span of use on these AC units, it is not surprising that dust and dirt have already accumulated in the filters and registers impeding airflow. It is of best interest to have the filters and registers be checked for an open and clean filtration and registration.

Low level of refrigerant

A low level of refrigerant can also cause the coils too be so cold to the point of freezing. It can also cause freezing because there is now lower pressure levels in the unit itself. And since there is reduced Freon too in the system, there will be a forced need to expand without changing the amount of expansions is equal to cooler temperatures. Moreover, when the fans are faulty, air movement is blocked.

Temperature outdoors

Using the AC unit when the temperature outside is lower than 62 degrees, then pressure on the inside of the system is going to drop, causing freeze up on the AC units.

Mechanical problems

Your air conditioning unit is an appliance that uses different components molded into one. With this said, when one of the many components will fail, then the whole air conditioning unit will be affected. So in situations where your air conditioning unit has freeze, then it is best to check fort the possibly faulty and problematic component such as refrigerant lines, blower fans that does not run or is clogged, and unbalanced.
