I have a 26 x 36 very well insulated garage built like a house (as contrasted to a pole barn) I have the 75k Modine Hot Dawg running on natural gas. Does a great job even here in Michigan. Keep T'stat at 50, bump to 60 when I work in there. Anything more and it gets too uncomfortable.

Had an old window unit air conditioner, so cut a hole in the wall and installed it up high ear the work bench. Didn't do too good until I put a fan on the workbench right under it aimed at the workshop area. THAT did the trick.

I rigged up a heavy cord that allows me to plug in my big generator in power outages in place of the air compressor and back feed power to my house. Just isolate it from the outside world and use only the critical circuits (beer fridge, well pump) Works quite well. No exhaust and noise problems in the house.

Neighbors around me have permanent backup systems that come on automatically when power goes off. Pretty slick, run on natural gas. Other than the noise, you'd never know the diff.
