22.214.171.124: Maintenance of Air Filters
Filters in forced-air heating and cooling system equipment should be checked and cleaned or replaced according to the manufacturer’s instructions on a regular basis, at least every three months (and more often if necessary) (1).
RATIONALEClogged filters will impede proper air circulation required for heating and ventilation. Poor air flow causes pressure imbalances in the system and can result in the premature failure of equipment. Low air flow can reduce heating and cooling performance of the system and cause cooling coils to freeze up.
