Yes. Due to a variety of moving parts, liquid refrigerant and the tendency for dirt and dust to collect on sensitive parts, central air requires maintenance. Air conditioner filters are the first line of defense for the unit, blocking dirt from entering the unit’s evaporator and causing damage. The coils of the evaporator and condenser can also collect dirt and lose efficiency. Coil fins can also become bent, and condenser drains can become clogged.
