I work in the A/C. It is very nice to have, and allows me to work hard without over heating. But, even without a/c my shop stays fairly cool. l I am against a/c at home, there is no reason for it. I can sit in my basement, take a cool shower, or go for a swim if it is too hot. The temp drops bellow 80 every night, so sleeping is never an issue. I don't see the point of using the extra electricity. I don't have central a/c and i really don't like the look of window units. Being hot is slightly uncomfortable, but i can deal with it.
