Back in Aprin of 2012 I was done with a hot garage. They layout of the garage with the work area, bathroom and such make a mini split impractical.

This is the human door to have access to the back yard.
A few long screws and I can remove the door. The AC slides into the opening, or I can store it on the shelf right next to the door. On a 100 degree day it will keep the work bay very cool, in the low 70s. All these years later that AC unit just works, and it cost just 75 cents per hour to run. So at the end of the project, I am just not soaked in sweat. I have a heather out there as well.
It is pretty much a tie between the scissor lift and the AC to which is my favorite upgrade to my garage.
When that AC unit dies, I will likely upgrade to a 220 volt unit, but it still works great, I do drain the water out after use.
