a freind has a 27 year old brick 1100sq ft with central ac
house that was hot when 90 and above. it had plenty of eave vents but
none on the roof. we put a power vent for 1600 sq ft on the roof in the
center of the house and that really cooled that house down. the house
also had enough insulation ,trple pane windows and damn good doors.and
ac is adequate. it sits out in the sun in central ky. lucas
