rented a house on Goodland FL, south of Marco Island before we bought in TV, and to keep the house cool, they had a huge ceiling fan which sucked all the air from the house to the attic, and the difference in temperature was about 20+ degrees cooler with the fan on. .
Triangle Fans VIK Belt Driven Cabinet Exhaust Fan w/ Shutters 30 inch - VIK30 | HVACDirect.com was the fan in the ceiling.
We purchased this for the MA house as the 20 year old prior fan quit working.
