Gaps around your window air conditioner unit let humid air in and newly cooled air out in the summer; in the winter, heated air leaks out and drafty cold air comes in.
Help your window air conditioner cool more efficiently in the summer and prevent heat loss in the winter with Frost King Air Conditioner Weatherseal. These easy-to-install strips fit around your window AC unit to create a weather-tight seal that keeps climate-controlled air in and outside air out. Just cut the strips to size and tuck them around the sides of the unit and above and below the window sash.
