Ditto, do not allow covers to touch the skin. I have a portable 'garage' canopy. The kind you put up for your extra cars. They come in all sizes. Mine is 10 X 30....a 10 X20 that I added to although I could have got the size I needed but I happen to have 2. I did have to add 16" legs to raise it so the AC would fit under. Down side is during the winter during snowfall (just a couple of times here) I go out, sometimes at night, and push the snow build up off by pushing a garage broom up from underneath. Wind is a problem too so secure it. For some extra bucks you can use a metal canopy.
