We replaced the basement unit with a new 5-ton Hydron Module Revolution 2. New filter box/MERV 13 upgrade, connection to our existing AO Smith hybrid pre-heat water tank, and a new Honeywell thermostat that allows control from our smart phones (though I haven't downloaded the app yet).

$15K to our contractor. We've since received a $4,025 rebate from Eversource and a 26% federal tax credit that we'll take advantage of this tax season (if you can't use it all, you use the rest in future years). This nearly cut our cost in half.

Of course, all I needed to do this time was replace the failed unit. No ductwork, no fresh air controls, no drilling a well (which I'm guessing you'd opt for given all your ledge), no connection to the interior unit. My point however is to not overlook the incentives that might be available.

I've said before on this forum, if geo is available, we'd never go with anything else. Such a comfortable heat source, eco-friendly, safe (no fossil fuels), quiet, very low maintenance and it's saving us lots of money in heating (and cooling but we seldom use that since we're usually at the lake in the summer).

Good luck and the house looks beautiful.

Very interesting--do you know what the payback period is for an all new geothermal system, including all the incentives? As msw notes, solar is about 6 years, I'm wondering how geothermal compares.
