1 air conditioner freezes up restricted airflow 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. To function properly your ac needs warm air flowing over the coils. When a filter vent or ductwork is clogged it can restrict air flow which causes moisture to build up on the coils.
