82/47.....
Just installed a whole house fan yesterday....our valley radiates so well, even on hot days with lower humidity, it was almost a no brainer. Wish I was familiar with them sooner. In 2 hours, it took the house from 80 to 70, had to turn it off, it was actually getting too chilly inside by 10 pm last night. We got one that works for our 2600 sqft house and on high only uses around 500 watts.
