I have just purchased a Cape-style home with an unfinished second floor. I would like to mount a large fan in one of the windows of the second floor to pull air through the stair well from the first floor. Whenever I look at fan literature, I see whole-house fans and attic exhaust fans. The attic exhaust fans are usually quite small and have relatively small capacity. The whole-house fans, on the other hand, have much greater capacity, but are usually shown mounted in a horizontal position on an attic floor. (The Cape of course has no true attic.) What is wrong with mounting a whole house fan vertically in a window at the end of the second floor??? Or could two smaller capacity fans be mounted vertically, one in each of the two second-floor windows at opposite ends of the second floor? Help much appreciated. Frank
