,The first consideration should be, are the garage walls and ceiling insulated? If not, then forget it, no AC unit is going to stand a chance against the hot walls and ceiling.
[center]That being said, why not place a large portable box fan in the entry door from the garage to the main house? This of course is assuming your working in the garage and the main home unit is running.[center]
There are also portable rollabout AC units that you could exhaust to the attic or under the partially opened garage door. Exhausting to the attic would not be the best alternative unless you have power attic ventilation, which by the way I'm looking into as I write.
Just some thoughts
