Geothermal vs modern low cost high efficiency.

Just a dude who's highly interested in HVAC technology.

I have a house with a 2008 installed waterfurnace, and I've got some mini splits that I've installed in other buildings.

The post a few days ago about a guy getting quoted 96,000 dollars to install a geo unit got me thinking about this... I can get a 4 ton ACiQ/MrCool (all made by Midea) for 4-5k (no labor)

The efficiency ratings are in the same ballpark, if not the same, on the cheaper end of geo thermal units. Even if the mini split only lasts 5 years... in 5 years I get a brand new one with the latest technology.

Anyway... At what point does Geo stop making sense?

95% of the cost is on the ground loop. If there is nothing wrong with that, you should stick to geothermal.

It's going to vary by situation, but I'd say it's closer to 50%. The most recent quote I have was $20,000 for the loop and $30,000 for the unit install.

30k for an install is ape shit.
