I've looked into the freestanding A/C units. Can't find one big enough (all the calculators say that for 800 sq ft I need at least 15000 BTU). And I'd have to cut a hole in the ceiling/roof for the vent hose, as the available windows are far from where people spend most of their time in the room. I'm not at all ruling that out, though.

I'm getting someone out here to advise and quote on a split-system A/C, also on solar vent fans and anything else that makes sense.

Ted, Portland weather is different from Seattle. I grew up in Seattle for a while (Kirkland actually) and it is cooler, more of a maritime climate. I thought Portland would be the same, but turns out that being 100 miles inland means we have higher high temps and lower low temps than you guys in Seattle. I love Seattle, I'd move there if the opportunity presented.

I'm also going to drill a hole in the ceiling and measure the temp between the rafters as well as visually check on the insulation (hopefully there is some).
