Do you know anyone who uses a geothermal heat pump for their home heating and air conditioning?
Also known as geoexchange heat pump or ground source heat pump.
How much did it cost them, and how well does it work for them? Do they ever have to supplement it with ordinary heating or air conditioning, or is it always plenty, even in the most extreme weather?

I had a geothermal unit (water to air heat pump)installed in October, 2007. I paid approx $8,000. There has not been any extreme weather here in North Carolina, but I don’t have a supplement system (except for a fireplace (winter) and fan (summer).. This unit was a replacement for water to air heat pump installed when the home was built in 1977. So I have used water to air heat pump system for 30 years and am pleased with the results. You should take advantage of the tax credit incentive! My system is GT048HZN STandard low temp Florida Heat Pump, 19EER/ 4.5 c.o.p., 4.0 ton nominal which was connected to EXISTING ductwork and water supply.
