- "For an average fuel oil homeowner in New York, switching to geothermal would save 110 tons of CO2 and $35,000 over 20 years," Hannun said. "For the average propane home, the homeowner would save over 130 tons of CO2 and $63,000 over 20 years," she said.
I'm smack in the middle of my geothermal internship, and funny to see this crop up. As I'm here I've learned HVAC is responsible for 32% of our carbon emissions in the US. As it turns out with both NY rebate and Federal tax credits, the system price is dropped by a third, and from there the system pays for itself within 3 years. Now, this system that Google intends to use is far and away not like to be anything like what I'm learning... but for a tidbit, one of the company's systems I'm with cost the owner only $65 in HVAC expenses last month, and that's the least efficient system; an updated system cost the owner $18.
GSHPs make a lot of sense if you're willing to eat the equipment costs. That's a leeeeeetle system, I bet.Installation of a Dandelion system would cost a homeowner between $20,000 to $25,000 upfront, or between $160 to $180 a month over 20 years, the company said.

From what I understand, the biggest expense is the installation of the loop system. Vertical means drilling which costs about $12/ft where I am now, and drilling happens in 20 ft increments. The pumps themselves we install can range from freakin' $200 to upwards of $2k - where some of the systems are just two high end pumps put together. Either way, the rebate program I shoulda linked helps with biting the bullet in the short term. On the side of Google... what I'm reading is that they are looking for a way to streamline installation and pumps for homes. I'm getting the same impression as you. Don't think it'll work out, but excited to see their brand enter the market.
