As a result most of the cool air continues to stay around the evaporator coil and fins causing the temperature around them to drop.

Air conditioning freezing up causes. But when theres little to no air flowing over the cold evaporator coil it quickly frosts over because theres less heat to absorb.

A clogged filter reduces airflow which could be the root of the problem. If something prohibits the warm air from blowing over the coils this causes the evaporator coil to allow the refrigerant to cool too much causing it to fall below freezing and ice over. In many cases freezing up AC is simply the result of a poorly configured thermostat.

Check out for any blocked or closed returnsupply vent. You can check this quickly by leaving the system running and checking if the fan is spinning visual check only. Low refrigerant levels make the coils too cold and a faulty fan prevents air from moving.

Before reading further go ahead and get a quick overview of how an air conditioner works. However if something in the air conditioner malfunctions the whole system gets disrupted. When air flow or air circulation from the unit to the room and vice versa is restricted the exhange of thermal energy between the air conditioner and the room is restricted.
