What kind of regular maintenance do ACs need and how often?
The outdoor unit of a central home air conditioner should always be covered in the winter in the areas of the country where air conditioners aren’t generally used due to cold weather. Air conditioner units can be covered with pre-fabricated kits or by simply measuring and cutting a 2 to 6 mil plastic sheet to cover the unit. Conversely, the cover should be removed before the unit is operated in the warm season months. The fins on the sides of the unit should be checked for debris before operating as well. The air flows inward and upward into the unit from the sides and any blockage will diminish the cooling effectiveness of the unit.
