Use Fans Wisely
If you have a few fans stored in your garage or attic, they can be lifesavers against the heat. But be strategic about placement. Place some of your smaller, box fans in the windows to let cool air in. Or create a makeshift air conditioner. Take a bowl or a large pan, fill it with ice and place it in front of the fan. As the ice dissolves, the air cools. DIY.
For ceiling fans, turn them counter-clockwise to move hot air out and keep you cool.
