HomeDepot.com, Amazon.com and Walmart.com have covers for both window air conditioners and outdoor units. Some covers are made of quilted fabric, while others are made from vinyl. Some have fleece liners. Users' ratings are displayed for several of the covers.
Air conditioner covers protect appliances from environmental factors, such as dust, animal hair, dirt, leaves, rain and sun. Covers for window air conditioners also help prevent drafts from entering homes.
