This cost seems high to me. Installed a horizontal loop geothermal system over an acre of land in Northern Ontario. Had the trench dug out with an excavator (approx 12 + ft deep) and the same guy lay all the pipe and back filled for about less than 10k. If you look in the classifieds you can hire an excavator/operator for about $1k a day. The guys did it all over a week. Our whole system came in under $30k. It was a few years back but I don't think it would cost 70k today.

Not sure if you were aware, but the cost of building materials such as wood and also hvac has went up massively. The same central heating and air units a year ago would have cost maybe 20k with a full install. We got three quotes for three different firms that do geothermal. And as I mentioned elsewhere, if I installed a horizontal loop, I'd have to cut down a ton of beautiful 100 year old trees surrounding the home. I'd rather not do that when there are viable alternatives. The cost of higher electricity usage isn't a big deal as I've got 48 bifacial solar panels on the barn that run to the home.

  Consider closed cell spray foam and you will probably make out better with a traditional high efficiency system than you would with geothermal and regular insulation. If you went with geothermal and spray foam your heating and cooling/comfort costs would be less than someones Starbucks habit but I can understand the initial cost might not make sense for some folks.

    I've got a looooot of solar panels, so the electricity is "effectively" free. This is good advice though, thanks!

That's great if you have enough land and don't care about restoring the yard, I was quoted $30K to install on less than an acre, including restoring the landscaping.
