Ceiling Fans

I've found people have often said that you want a fan to be blowing down on you in order to keep it running.  Well, this isn't always the case.  If it's cooler outside, having the fan blow upward toward the ceiling will cause air and heat to flow out through the roof.  It's not as good as having a fan blow up into the attic, which is doable, I've seen it, but this not being possible, having the fan blow up will cause a vacuum which will cause air to flow in from the outside.  I wouldn't recommend this though if it is already cooler inside than outside.
