What is the payback time in electric costs if you pay $500.00 plus for these attic fans. Sales people them cannot give a specific reply. If you only reduce the attic temp by 10-15 degrees for the hottest part of the day, then much will one save on electric cost for that part of the day! How do you calculate that ? How many special fans are on the 50,000 plus homes in the villages? When look at the entire State of Florida, I wonder how may have special venting other than what the home is built with!
