I have bought a portable air conditioner that has a window kit (am renting, so can't cut holes in walls etc). The problem I have is that the only "window" in my bedroom is actually two doors. I can keep one closed and open one, but don't have any idea how to seal off the opening to stop hot air entering. Would LOVE some advise.
You'd have to install a temporary solid wood door with a hole cut in it for the a/c unit and build a ledge for it to sit on that's well braced. Some home centers sell damaged doors at cheaper prices...you'd have to find one to match the existing door size. A/C units discharge water that's collected from the room so you'll have to figure out how to drain that off as well if it's not placed on an outside wall. You may be better off placing the a/c unit in a close-by window and pointing a fan towards your bedroom to get cool air to it.
