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

Being in AZ I would consider a swamp (evaporative) cooler. A downdraft
model would easily install on a flat roof, and give you cooling when
needed, not just at night. I'll bet most of your neighbors have one,
(or
A/C).

Yes we have AC. Some -- but closer to a "few" rather than most -- have
swamp coolers but they're simply a form of air cooling limited to about
20
degrees of cooling. When temperature get over 100, 20 degrees isn't
enough.

But we're talking about a different animal here. A WH fan "moves"
existing
cool air supplementing AC at a much, much cheaper cost.

A WH fan will move your conditioned air into the great outdoors, won't
it? Unless you're talking about a recirculating type fan, which you
already have on your AC. Nice weather we're having now, eh? Tom


A WH fan will allow you to turn your AC off and save a lot of $$$. Are you
saying that expensive AC is better than drawing natures cool air through
your house?
