09 Dec Check Your Air Conditioner
Disconnect the electric power before you check your air conditioner!
Disconnect electric power to the outdoor condenser on your air conditioner and clear it of leaves and debris with a vent brush, power blower, garden hose, or the brush attachment on your vacuum cleaner.
If the cooling fins are exposed, be careful not to bend them. (If your yard has lots of trees and plants, wrap fiberglass mesh around the condenser coil to capture pollen and leaves. Replace the mesh as needed. Don’t allow debris to block airflow.) Vacuum the grille and register inside the home to ensure good airflow. And change your furnace filter.
Level up the outside unit. Sometimes they settle and because the fan spins horizontally, the bearings will wear out faster if it is not level. If it starts squealing, call a professional!
