92° outside here at my house. Only 78° in the garage. No air conditioning running, only fans. I keep the insulated garage doors down to keep the heat out. Been this way for years. Lovin it...
how many trees do you have around the garage? is the roof insulated? which way does the door face.
I have one large tree on the east side, no insulation and it faces south. It'll stay cool on days like today until 10 or so, then, to warm to work.
maybe I should use the fans I have.
