We plan on selling our house in another year. We have a ground loop Climatemaster geo system that was installed in 2011. It is perfectly sized for the house and has been rock solid since installation. Not much in the way of comps in our area that have geo systems. Can we expect to have any premium added to the house listing because of the geo system? What are others seeing in their area? We do live near a college area, so home buyers here often have more interest in energy conservation / "green" building, though not sure if they're really willing to pay more for these things. My thoughts are that it is a plus just due to lowered heating and ac costs to someone not necessarily looking for geo heating. This might make the house more able to be sold vs other older houses in our area, but not necessarily reflected in the sale price. I can give the our real estate agent any graphs she wants as I've kept records of our electrical usage monthly since before the install. For us, the system has been great, and already paid itself off in fuel savings, so any extra at time of sale would be a win-win. How best to market?
