Oh, I have no intention of installing an AC unit. Too much power. The swamp cooler is very interesting though. Since I live in what passes for arid land in Canada, they, or some invented version of, might work for me. I'm thinking something that I could add to a powered vent fan. Does anyone have pictures of, or would be willing to describe how they operate? Do they fit into the hole for a 14" vent? How well do they work, under the correct conditions?
