Does anyone here have Geothermo?  I've been reading up on it and visited with a guy at the local Homeshow today and he claims I can heat, air condition, and heat my water for between $600-$800 a year with Geothemo.  Price would probably be 20 grand but there is a 30% tax credit and $2000 rebate from our utility company which takes 8 grand off the top.  I'm getting close to needed to replace what I have - so it looks a bit attractive.  The good news today was when they had the big drawing I didn't win the 42" TV - but I won a remote car starter and 100 Sq. Yards of free carpet cleaning.
