Whenever the outside temperature drops below inside temps, open some screened windows and flip on the fan to pull cool, dry air through the house and exhaust hot air through your roof vents.
For a morning “pre-cool,” run your whole-house fan just before sunrise, then close the windows to seal in the cool air as the day warms up. In the evening when outside temps dip, turn on your fan to cool off the house, which takes about 20 minutes for a 2,500 sq. ft. house. In general, whole-house fans are more effective in multi-story homes than single-level.

A whole house fan is definitely a cheap way of cooling a house plus it is more energy-efficient compared to AC units. It is really an awesome alternative. We've been using our whole house fan for more than year now and no regrets about it and i know more and more people are turning to whole house fan as their cooling system.
