Home weatherization is an easy and affordable do-it-yourself project that can be done in as little as a weekend. Air conditioning units can provide added comfort during the hot weather, but oftentimes require protection from the elements during the cold-weather months. The Duck® Brand Indoor Window Air Conditioner Cover is a reusable, easy-to-install cover that is used inside your home around your window air conditioning unit to seal in climate controlled air and seal out drafts, dust and insects. Use in combination with other Duck brand weatherization products for added comfort and energy savings.
