I love the concept of geothermal and have done some research in the past. My husband and I are working on house plans and would love to incorporate geothermal. We've been given a general quote of $16-$20,000 by the geothermal expert in our area. Upon talking with the bank and a general contractor/house designer they have both discouraged us by saying that over the lifetime of our mortgage, that $20,000 to install turns into $50,000 and would we really save enough on our utility costs to justify this expense?
Comments are welcome, please.
