I have a huge attic. The shingles are black and the attic builds up a lot of heat, which keeps the bedrooms pretty hot all spring and summer. I need to ventilate the hot air so I originally decided to install some appropriate sized fans on a temperature controlled switch.

I recently saw some whole house fans advertised. They install in the upstairs hallway and open louvres in the ceiling, which draw the warm air out of the house and out through the attic vents. I wonder which might be better for the house.

The attic fans can work anytime to vent the attic, but the whole house fan can take advantage of some cooler nights by drawing in the cool air through the windows when I otherwise would have to run the AC. The only disadvantage would be during hot days and nights, I couldn't run the whole house fan as it would draw in the hot air from ouside. Which should I get? Maybe both?

I would be interested in hearing the opinion of some of you that have one or the other and the advantages and disadvantages of each.
