Ground source/geothermal would significantly reduce your heating costs but it would be significantly more than 10k. For that large of house something like 40k+ wouldn't be out of the question, with the largest expense being drilling.
I personally think geothermal is great, sadly New England's geography makes getting a ground loop installed more difficult. In the midwest lots of people would do a horizontal loop by trenching like 8 feet underground laying pipe in there. In many parts of new england that isn't really viable with all the rock so vertical drilling is used which is significantly more expensive.
- snuxoll 4y agoMy brother-in-law lives in NE and has installed mini-splits and has overall enjoyed them. A ground source system would be "the best" for that region, but if you're not doing a new build then air source works just fine there with the correct equipment.
- sbradford26 4y agoI also live in NE and we recently installed a mixed system. We have mini split units in the upstairs and a ducted air handler in the basement all attached to a cold weather heat pump outside. It has be working great for us so far, but we have the advantage of having a smaller house so we only needed one 4 ton unit outside. Our house was built in 1973 and originally had electric baseboards and then was converted to an oil boiler with hot water baseboard. So retrofitting a heat pump was an interesting task.
