Whole house fans

[Doug Crf]

I am wondering if any one has seen a wisper dual drive fan from lowes
in a ceiling and working.It looks like a pretty nice one but I am wondering
if it would be to small for a 1350 sq foot house.
Any one have any input.
Or if you have experince in this type of thing may be you can help me and look
up the fan and see what you think.Just search on line Whisper dual drive fan
and it will come up.It is kinda expensive but sounds pretty good.I just do not
want to get some thing that is to small.
I am wondering if it might cost so much because of how easy it is to install.

Thanks Doug

Air flow is 2200cfm - if you've got a two story home, it's probably adequate. For a single story at 1300sf, maybe a little on the small side.

The high price tag is because of the bells and whistles. Instead of the typical ceiling shutter, it uses a standard return air type vent, and then a thick insulated lid on the attic side that opens by motor when the fan's running. And a high tech remote control instead of the typical on/off or timer switch.
