Where I’m Most Effective?
Let the Night Air In. During summer months, temperatures may drop during the night. If this is the case where you live, make the most of these refreshing hours by cracking the windows before you go to bed. You can even create a wind tunnel by strategically setting up your fans to force the perfect cross breeze. Just be sure to close the windows and blinds before things get too hot in the morning.

Bring Cooler Air In. At night, when the air is cooler, it makes sense to bring as much as possible of that cool air into your home. You can just open the windows, but a window fan, which costs less than $100, can pull in cold air much faster. A typical window fan uses no more than 70 watts of electricity.

If you employ this practice in every room, you can expel the hot air from your house, thus keeping it cooler.
