My house is 4 foot off the ground with a complete slab under it. I had the house raised due to one corner of the house flooding when it comes a very heavy down pour. It is rare but has happened in the past. Most of the time it is very dry and cool under the house. I live on the Gulf Coast.
I was thinking of putting an insulated duct with a fan to draw the cooler air from under the house into the attic on days when the attic temp is greater than 100 plus degrees. Insulated duct would be in a closet in the middle of the house.
Is this a good idea or not? And do you know anyone that has done this?
