Can anyone recommend a geothermal heat pump contractor in the Boston area? Thanks!
Well unless, for some reason, you don't want to go with DX (the most efficient form of geothermal), there are only 2 players in the industry. American Geothermal and ECR. If you go to their websites, they will direct you to local contact in your area.
Please see if this site is helpful.
