I “acquired” a new 15,000 BTU window a/c unit and wanted to use it in my garage, but did not want to modify my wall and outside stucco for the hole, nor to install a window as the bracing and building permit seemed too much of a headache and might take too long. I next considered cutting a square hole in my man-door, but decided not to once I came up with this idea:

This was some spare plywood I had laying around that is about 1/4”-1/2” too short length wise (i’ll have to put some foam or something along the top if it becomes a true concern). When not in use, I can easily remove the window a/c and store it somewhere, same with the board itself. I know I’ll have to put some asphalt shingles for the outside soon before it ruins the board, or weather seal it. Undecided. I was going to consider putting a platform for the window a/c to sit upon, but it fits evenly and snugly right into the hole.
Now, I have a/c (even if it’s just a window a/c) in my shop. We have had about 2-3weeks of 100 degree days here in Reno, NV (happens every year) which has barred me from getting in there even with R-19 insulation batts in the ceiling (it help alot, but still).

How do you get in and out? “Acquired” makes it seem like you stole it!

the board dry fits into the door way, snuggly. I may have to figure out a way to brace it in during high winds. but that is not a concern right this moment. I will add a handle or a 2×4 board for handles to easily install / remove it.
“acquired” here means it was given to me because of a slight cosmetic defect (a scratch) from a national warehouse distribution center that sends cosmetic items back to factory if it’s economically viable (apparently, small items like this a/c are not considered worthy of the hassle to send back)

Doors are cheap enough I would buy a second one and fit it to the door.

I guess if that works for you and keeps you cool…the time spent constructing that could have been time cutting a nice hole in your wall, with all due respect.

funding is at a all time low. i needed “something” to work, temporarily. once some time passes and the wallet likes me again, i do plan on doing a properly installed window (it would be nice to have a window in the shop)

A friend of mine did something similar many years ago. He replaced his screen door with a solid door with a A/C unit in it. When he wanted to go in or out he would just unlatch the hinged door and swing it open with the A/C in it. He would just lock the interior door when not in the shop. Said it was easier than constantly opening the big garage door.

Back in 1983, I installed an AC (w/heat strip) in my garage. We had closed it in by removing the doors and framed in two nice windows. I cut a hole in the brick wall and framed in the rough opening. It fit nicely and looked good. You can do it! :-)

I like it, and if it gets the job done then it’s well done! It sucks working in the heat, and you’ll be able to get more done safer now.
