Set Your Ceiling Fans to Rotate Counter-Clockwise
A ceiling fan isn’t a set-it-and-forget-it appliance. In the summer, the fan blades should rotate counter-clockwise (as you look up at it) to push the air straight down. Increase the fan speed on really hot days.
Cooling Curtains
Sometimes opening all the windows just doesn’t cut it, in which case, spray a sheet with cold water and cover the window’s opening. The breeze will hit the sheet and pass through the cool, damp fabric, which can help bring the temperature down in your home.
Make a DIY Air Conditioner
Feel like getting crafty? You can create your own air conditioner by using a fan, 3/8 copper coil, a water pump, ice, cooler box and a plastic pipe.
Turn On Your Bathroom Fans
