Put a 15.1K BTU/Hr AC unit in my work garage. There was a perfect place for it above the header over the window. It has a remote control so no need to climb to change controls. It weighs 100# so had to come up with some way to raise it. Location for it is about 8' off the floor. A beam made from two 8' 2X6s and an 8' 2X4 provided a 4' extension to the cherry picker boom. Cut a hole, added a 2X4 on each side of the hole, then another pair of 2X10s for the header above the AC hole, a stubby 2X4 to the top, and installed the outer cabinet. Its cooling now.
Nice! Now u can work in comfort, be more productive and not have to be totally dependent on weather condx to work on projects.
Come to think of it.. It was around the time my window unit stopped cooling that I kinda stopped going out to the garage.. That was years ago. Gonna have to look into correcting that.
