Blasting the AC all night may be great for sleeping, but it's not so great for the environment or your bottom line. Give your budget a break by using a fraction of the energy with this simple tip to make your hard-working fan extra effective.

Point your fan so it's blowing air out the window.

This advice may seem counterintuitive, but trust. Pulling out the stuffy inside air will draw in fresh cool outside air much quicker (provided you have another window open). I've been hip to this trick for a few summers now, and I can tell you that it works like a charm.

Try it tonight — you'll see.
