I have the laundry in a full 3 car garage that faces East. I live in a grove of large Oak trees that provide lots of shade. Cool in the morning. But it gets very hot during the day. When I moved here full time I wanted to get it air conditioned. I tried to get quotes from 3 different AC people. They all said that it was against code and wouldn't bid on it.
Tried the propped attic door. No help. Next I Installed some real nice motorized garage door screens and tried fans to exhaust the heat. No significant temperature drop.
Next I insulated my attic and garage doors. Got a few degrees temperature drop. My guess is less than 10 degrees lower. Still very hot in the afternoons.
Finally, the code changed this year. They now allow AC to be put in garage, but they call them "dehumidifier" instead of air-conditioning. Works for me. Now I am very happy! The space is usable all day long.
I put a 2 ton Mitsubishi mini-split in the 32' x 32' garage. $5K. Love it!
You mileage may vary.
