Does it make sense to install a whole house fan in a finished attic?
Before I went to the expense of buying a large whole house fan… I’d try out a window fan. Set it to exhaust out one window, and open another across the space, so you can get a good pull thru the area. Or even use a pair of them… one to pull air from outside and one to vent out.. or both to vent out, with windows open downstairs, for fresh air to be pulled up thru the home. Personally.. I’d lean more towards a window air conditioner than a fan…I like it cooler, hehe. A whole house fan will have the ability to move more air… a larger volume….typically, you would leave windows on the bottom level open a bit, to pull air up from the first floor thru the upper floor space(s). The key to using either the window or whole house fan is ventilation… you MUST have some source for new air to be pulled into the home… this means, usually, leaving some windows gapped. Shutting doors will slow or stop, the air flow, and void your attempt to cool the room.
