Five Ways to Keep Your House Cool
Close your blinds. Close your blinds and curtains during the day to block the sun's heat.
Open the windows at night. Open selective windows so that cooler night air is blowing in throughout the evening.
Cool down your house with fans. Position a ceiling fan, an upstairs window fan or an attic fan to draw off the heat collected in upper rooms and push the heat outdoors.
Turn off all heat sources. Don't use the stove or oven to eat. Eat cold food, or use the microwave. Incandescent light bulbs also create heat - switch to compact fluorescents or LEDs. Turn off your lamps and your computer when you're not using them.
- Make a DIY air conditioner. Put a metal bowl of ice in front of a fan, and adjust the fan so that the air is blowing over the ice. Or, use one or more 2 liter bottles and fill them mostly full of water, freeze them, then place them in a large bowl (to catch dripping water). Position a fan to blow on them. As the ice in the bottles melts, the air cools around them. The fan will blow that air at you.
