Since I need to replace my current hot-air gas fired furnace does anyone suggest that I should use geo-thermal heating and cooling. I live in the North Carolina mountains — temperatures ranging 20 F to 90 F. Occaisional 0 F every 3rd winter. My reserach shows an exorbitant amount of pipe to be buried to accomodate my 2400 sq ft heated area. I do have a slope that faces south and one of the many virtues of North Carlina mountains is lots of clear sunny winter days. Seems ideal if not too much digging involved.
Friends have installed heat pump with gas-fired backup heat. What do you think ??
thanks for listening; al

If you're all set up for gas, it'd likely be a long payback on a ground source heat pump (the proper name for geothermal) installation. No replacement for running the actual numbers though...capital cost and running cost of each option...then pick what makes the most sense. If you do decide to go with a GSHP, I got a contractor for you...best one in central and western NC.
