When there isn’t an adequate amount of refrigerant in an AC system, the pressure will drop inside the unit. This will then cause temperatures to fall in the evaporator coils—which can dip below freezing. When this happens, nearby water vapor can grab onto these coils and freeze.

Why is my AC unit freezing up outside?
Refrigerant lines can kink, fans can stop moving, filters can become clogged, and things can leak. Any of these things causes a drop in pressure, allowing the refrigerant to expand too much and become too cold. Refrigerant is also an essential part in ensuring a regulated temperature throughout your machine.
How do you unfreeze an air conditioner fast?
If the AC unit is blowing hot air, first try turning off your air conditioner but leaving the fan on so it can defrost the AC unit. The AC's indoor fan will blow warm air over your AC's frozen coils, helping the ice thaw faster. Also check for a dirty air filter, which could be causing air flow blockage.
What do you do when your air conditioner is frozen?
