I ordered a portable standalone air conditioner from amazon. The heat of a Texas summer combined with my west facing garage door meant that something had to be done to allow me to work for the next few months. I built a footer board that the garage door can rest on and allows the inlet and outlet air for the compressor while keeping at lest some of the hot air outside. I also fabricated a seal flap for the top of the garage door out of the foil bubble wrap stuff from Lowes.

So far, I’m generally pleased. It kept the garage at around 85 degrees today between 3:00 and 6:00 (although this wasn’t the hottest day) then quickly brought it down to below 80 once the sun went down. It also lowers the humidity a great deal. I never expected it to be 70 or anything like that but I think it makes it workable in the garage during the afternoons. I will update what I think of it after a few 100+ degree days.
