A geothermal system can work as good if not better than convential hvac system it all depends on the location

Ditto...I have it in my house (4200 sq/ft), and LOVE it...Mo has it in his house, as well as his bowling alley (7200 sq/ft w/16? ft sidewalls) and in the dead of summer while running 8 ginormous pin-setter machines and everything else in the alley I think he said his highest electric bill was well *under* $200...and those pin-setters create a LOT of heat, and Mo likes it COOOOLD in the summer! The cool thing about them is that you can have multiple zones w/multiple thermostats in different parts of the house...I cheaped out (addnl $3k) and didn't get that option, but we now wish we had...anyway, I would recommend the system.

Another option is a heat pump w/backup (uses same unit), which we have at the shop (6k sq/ft w/ 14 ft sidewalls)...they shine in the summer months, but with colder winters like you guys have, the LPG vs electric backup would probably be better.
