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

Condo board is going to have a lot to say about cutting holes and
adding electric loads, I should think.
Check the rules first.
