? Whole-House fans for flat roof house?

DonC · 2007-10-06T20:15:22+00:00

Hi all,In every house I've owned, until now, I've installed a whole-house fan. They significantly reduce AC costs and make for comfortable living. Alas, that was while I lived in Michigan in houses that had attics. My typical unit included a twist timer and variable speed motor.Now we live in southeastern AZ in a condo with a flat built-up roof so a typical attic unit won't work. But we still have frequent cool nights that would we could benefit from.Anybody here have any experience with WH fans in a similar setting? My research so far has been disappointing -- no variable speed fans and fewer available units : (Thanks

Usually called a swamp cooler in the USA. They have separate controls for the water spray over the pads and for the fan so can be used with just the fan for what you want to do.

Any whole house fan can work installed in the ceiling. you just have to be sure you have venting. Add a vent or enouh soffit venting to take care of the air blowing into the space above the ceilings.
