Great forum. This is my first post so here it goes.

I have an oversize three car garage that gets really hot & humid in the NC heat. I would like to add A/C in it. I was thinking about these units. What are your thought of them? Can the blower part of the unit be installed in the foundation or does it have to be in the wall of the house to the garage? Any help is greatly appreciated. Oh, how big will the unit need to be?
