How often should an air conditioner be cleaned and serviced?

Air conditioners should be cleaned and serviced regularly to ensure efficient performance and extend their lifespan. Filters, which can become clogged with dirt and reduce airflow, should be replaced or cleaned every 1-2 months during the cooling season. Coils should be checked annually, as dirt buildup can reduce the system’s ability to absorb heat. Regular cleaning of the area around the outdoor unit and the drain pipe, as well as inspecting window seals for room air conditioners, also helps maintain efficiency. For deeper maintenance, such as refrigerant checks or electrical inspections, a professional service technician should be consulted annually or whenever the unit isn’t cooling effectively.
