This air conditioner cover fits perfectly. Keeps leaves, twigs out. Snow piles up on top and then melts without going on the fan and workings of the inside of the air conditioner. No ice getting inside either. This cover was delivered a few days after ordering. Sturdy material and stretchy cords to attach it to air conditioner. Very satisfied with this product.A lot of manufacturers recommend just top covers because air conditioners are made to be in the outdoor elements and critters won't house themselves like they would with a full cover.
