Your recommendation for a whole-house fan as an alternative to air-conditioning in New England is an excellent one (in Real Solutions: Home & Garden Tips, July/Aug. 2007 issue). We love ours. However you mention just one vendor: W.W. Grainger at grainger.com, which sells traditional whole-house fans.
There is a new breed of highly energy-efficient whole-house fans with improved motors, remote controls, and automatic tightly sealing insulating doors, to avoid heat loss through the ceiling in the winter, which is a problem with traditional whole-house fans. They also fit between 16″ on center ceiling joists.
Some sources: housecooler.com (Tamarack Technologies, a Massachusetts company), efi.org and hvacquick.com (AirScape brand). These new whole-house fans cost more up front but they can save more in the long run, especially compared with air conditioning that adds to expensive peak electrical demand and CO2 emissions.
