Make sure there is plenty of clearance on all sides so that the unit receives plenty of airflow. Clean inside the cabinet and remove grass, twigs, leaves, nests or other debris. Clean the outside of the cabinet with a mild liquid cleaner and soft cloth. Wash the fan blades and coil to remove contaminants that can cause rust or corrosion.
