Help keep your home warm and cozy during the colder months by winterizing your indoor AC unit with an air conditioner cover. One of these covers will keep your air conditioner from being an energy-wasting hole in the wall during the fall and winter. Each one is made from a polyester and cotton blend and features an insulating polyethylene foam liner. Simply place the cover over the unit and fasten it in place with the included removable vinyl tape to block cold air from entering and warm air from escaping your home. Choose from three different sizes and remember to add an extra inch to the width and height to ensure the cover fits properly.
