I know this is not a new problem, but I am sure looking for a new answer. In a typical through the wall air conditioner, I am having problems with the outside can (through the wall mounting chassis) conducting cold to the inside, sweating when it contacts the warm air , condensing and causing mold on the sheetrock. Yes I know an insulated box would help, but how can you accomplish this 3 stories up? Has anyone had this problem and come up with a solution?

Place an insulated box over the interior face so the warm air can't connect with the cold sleeve? buic
Thanks BUIC, hadn't thought of covering the inside? I wonder if that is something the mfr. would have? I have 13 of them to do.
I don't know if anyone sells them.
I made mine out of 1x4 and 1/4" ply. Lined with 3/4" foam and it slips over the molding around the sleeve. Two screws hold it on nicely. Painted to match the wall...buic
Thanks Buic, we talked about your idea at lunch and are going to play with it a little!
Unless it's very tightly sealed that just makes the problem worse. The problem is not the warmth of the air but it's humidity. The box needs to be a vapor barrier more than it needs to be insulated.
