Thanks Arne& Sammy, Local contractor wanted 2k for the unit plus install, similar prices on line, smallest unit I could find is 9k btu, a little over kill far a 10 X 12 room that is already 76*, going to Lowes now to get the Frig. 5K btu unit, $119, heat wave hitting us, so want to get one before they run out! Going to discharge into the garage for now, & when I'm happy with all will build a plenum so it discharges into the attic, fortunately there is a big roof vent right above where I'm putting the unit. Thanks again for all the responses, Roy
