Can any of the pro installers tell me if there are any big advantages or disadvantages to either one of these product lines. I'm building a new 7,500 sq ft house with radiant floor heat in walk-out finished basement and on first floor. Only two HVAC contractors in my area do geothermal. Their bids are similar in price. One uses Geocomfort and one uses Waterfurnace. I know about the 3rd party warranty on Geocomfort. Has that changed recently? Any advice/recommendations would be greatly appreciated. Thank you!
