I paniced with the high temps and went to home depot and bought a 5000 btu air conditioning unit. Well like it said in the owner's manual, the a/c unit keeps tripping the breaker. plus it generated a lot of heat so its pretty much became counterproductive. wiring the ac unit to another circuit would be either ugly(run a cord up the stairs) or a lot of work (cut through floor and walls). how loud is your 6" inline? links would be great.
