Advice on thru-wall AC units
July 4, 2007 7:31 PM Subscribe
I am moving into an apartment with a pre-existing wall hole for a thru-wall AC. (It's a Fedders building -- but I don't need a Fedders unit, right?) Despite my best google search skills, I'm having trouble figuring out what exactly I need to make this work. Help!

The pre-existing opening (about 27 x 17 x 17, I think it's the "A" chassis size) is lined/fitted with a thin metal box. Is that the same thing as the "sleeve," or is it just the way the opening was finished off when the building was constructed? The units I am looking at (which are wall/window convertible ACs -- waaay cheaper than solely thru-wall, and also with the lower BTU that's all I need for my small room) are smaller than the opening. I know that if it's not a tight fit I could stop the gap with foam, but these are considerably smaller (28 x 12 x 12) -- can I put side extenders or something onto it? What about if the height? Is it a problem if the depth of the unit doesn't extend past the depth of the opening? Advice from anyone with wall unit experience would be appreciated!
