The whole house fans are awesome . . . when it's cool enough to really work well. We run the AC during the day and then ideally let the whole house fan do its thing once it cools down at night. Lately, though, it hasn't really gotten all that cool before bedtime. I somtimes turn it on really early in the morning to get the initial temp down.

Can't wait for the cooler nights that aren't too far away. My wife hates it when I put that sucker on high and chill the whle house down in <30 mins.
