Did you know you are supposed to reverse your ceiling fans for summer and winter? I vaguely remember hearing something about that but I can assure you I haven't been doing it. Here is how it works:

Rotating counter clockwise will pull the warm air up...pushing the cooler air down.
So...tonight I will go home, lay on my back in all of the rooms in my house and see which way the wind blows.
