23 Ways to Beat the Heat

Don't Blow Hot Air

Make a makeshift air conditioner. If it's hot but not humid, place a shallow bowl of ice in front of a fan and enjoy the breeze. As the ice melts, then evaporates, it will cool you off.
 
 Give your A/C some TLC. Clean or replace the filter in room and central air conditioners about once a month during the summer. If you have central air-conditioning, have the ducts checked for leaks, which can reduce a system's efficiency by as much as 15 percent, according to the U.S. Department of Energy. Seal any cracks between a window unit and the frame with peelable caulking or a sealant strip. These steps help ensure good airflow and keep the coils cleaner, which means more efficient and more effective cooling.
