The answer to 'how to clean air conditioner' is to regularly clean the air conditioner unit to maintain efficiency and extend its lifespan. This typically involves cleaning the outdoor condenser unit, indoor air handler, and air filters.
Start by turning off power to the unit and removing any debris or leaves from the outdoor condenser. Use a garden hose to gently spray the coils, being careful not to bend the fins. Then, remove and clean the air filters, either by vacuuming or washing them with mild soap and water. Finally, use a soft brush or cloth to wipe down the indoor air handler unit.
