Cooling Units

[hotwine]

The crawl space would work just fine as a space for exhausting the heat. You merely need to move the heat out of the way, in a manner that won't impact adjoining spaces. (Some people have vented coolers from one room into another, then wondered why the heated space gets uncomfortably warm. You won't have that problem by venting into the crawl space; just toasty, grateful little critters that live in there.)
