It was hot, Hot, HOT work. Bit it was totally worth it. The downstairs part of the house is bearable now, though we have fans running all over the place to get the air distributed. Hopefully we can get it to run over several days to get the overall temp down and then it won't have to run at full power to maintain (or maybe the heat wave will end). We are looking for another unit for the upstairs now, just in case.
