Thanks for the feedback folks. The quotation came back for $17k for the
Unico w/Lennox HS-29 Outoor unit. That's, um, a little out of my range.


I'm definitely going to look seriously at the other options suggested.

When you mention slowing down the fan, I'm curious as to how this is
done. Aren't the "single speed" units just that? Or do they really have
multi-speed A/C motors that can be run with different settings? Note
that I'm a newbie at A/C but not at power electronics. I've set up
variable speed drives on my machine tools, no problem. Could I simply
run a VFD drive for the A/C fan in the same way? Heeding, of course,
the warnings about coil freeze.
Any further feedback would be appreciated.
