I'm thinking of doing it. For some reason my girlfriend's house gets HOT and I mean HOT. If I'm super hot and need AC you know there is an issue. We didn't get the AC put in until like early June last year and we were dying. With my back I wasn't able to bring it from the basement myself. Finally I couldn't take it anymore, I walked it across the basement floor, got it up each step, slide across the floor and my friend helped me get into the window. When I uninstalled I just left on the floor in front of the window.
The issue is the bedroom...she has this MASSIVE uneconomically friendly AC that came from the original owners and weights like 100 pounds. I'm just going to have to buy one I can lift.
