Terry, I think you're just a bit Florida-centric in this statement. 
It's just not possible ($$) in the northeast without an extremely 
expensive system, which you will seldom find up here (too much money 
is already being spent by residents to keep their houses heated, 
while you guys are worried about turning up the AC at the same time 
of year).
