Open Those Windows

Be sure to open windows when the outside temperature is lower than the inside. Cool air helps lower the temps of everything — walls, floors, furniture — that will absorb heat as temps rise, helping inside air say cooler longer.

To create cross-ventilation, open windows on opposite sides of the house. Good ventilation helps reduce VOCs and prevents mold.

Fire Up Fans

Portable fans: At night, place fans in open windows to move cool air. In the day, put fans where you feel their cooling breezes (moving air evaporates perspiration and lowers your body temperature). To get extra cool, place glasses or bowls of ice water in front of fans, which will chill the moving air.

Ceiling fans: For maximum cooling effect, make sure ceiling fans spin in the direction that pushes air down, rather than sucks it up. Be sure to turn off fans when you’re not in the room, because fan motors give off heat, too.

Whole house fans: A whole-house fan ($1,000 to $1,600, including install) exhausts hot inside air out through roof vents. Make sure your windows are open when you run a whole-house fan.
