Dry wall is not my favorite thing either but it has to be done!
The new whole house fan is much better and is sealed very tightly. It will cut down on drafts and since it is very quiet compared to the other one, we will be able to use it more
No drafts??
I thought the point of a house fan was to suck the air through the entire house at mach speed to help everyone feel cooler with the windows open and no AC?
