      Clean the evaporator coils (inside the front grille) and condenser coils (outside of the unit) and allow your unit to dry completely.

   4. Clean the Air Filter.

      Check the air filter and wash with lukewarm water.

   5. Cover the Air Conditioner.

      Cover the air conditioner with a waterproof cover. Use vinyl tie-downs to secure the cover in place.

      Throughout the winter season, periodically check your unit and remove any snow, ice and/or debris from the top of the unit.
