Can a dirty filter cause AC to freeze?
A Clogged Air Filter Can Cause AC Leakage As the refrigerant evaporates within the indoor condenser unit, the evaporator coil absorbs heat from the air blowing over that coil. However, if the air filter is too clogged up, warm air is restricted, which can actually cause the coil to freeze. This is a two-fold problem.
