When operating the system, homeowners open only a few select windows, 4-6 inches each. This will greatly improve the cooling breeze that is felt. Homeowners must be sure to open windows far enough away from the fans intake in the room that is being cooled in order to feel the breeze. This way, the air will be drawn across the room cooling it in its entirety.
As the fan continues to run throughout the nighttime and early morning, more and more heat is pulled out of the mass in the home, such as furniture, walls, flooring, etc.
When heat is pulled out of the mass within the home, the home becomes truly cooled down.
Then, in the morning, before it begins to heat up outside, the fan is turned off, windows are closed and blinds are drawn in order for the home to resist being heated up as quickly. When the homeowner comes home at the end of the day, the house will be cooler and more comfortable because it resisted the heat better than it would have without the whole house fan. This is why the A/C doesn’t have to work as long or as hard.
The homeowner will continue to use their air conditioning on occasion when the outside temperature does not cool off enough during the early morning and nighttime hours, however, they won’t need to use it as long or as often.
