Can I use my AC within a special box that can be installed into my wall to build it a wall AC?
Answers: Probably not. Standard window a/c unit draw air through the louvers within the sides, and eject out the back. "Through-the-wall" unit typically draw through one side of the back, and eject through the other side of the put money on. Your standard window component will not be able to "breathe" even if you find a cabinet to mount it within.
if you put it into the wall youl have to own something allowing the air conditioner to breath or it will overheat and burn up the heavens conditioner and possibly cause a fire so as long as your nouns conditioner can breath it should be okay
