9 ways to cool down air-conditioning costs
No need to invest in fancy fans. Krigger says the key is to circulate air inside the house. If possible, locate fans on your house's upper level and open windows on a lower level. If you live in a one-story house or apartment, you should close windows near the fan and open windows in rooms far from the fan, preferably on your home's windward side, according to the U.S. Department of Energy.
Moving air also helps evaporate the sweat from your skin, says Paul Scheckel, an energy efficiency consultant in Montpelier, Vt., and author of "The Home Energy Diet."
"Evaporational cooling is an incredibly efficient process for removing heat, and our bodies do it all by themselves. A little help can increase the cooling effect," Scheckel says.
