Interesting. Well, I hope it works out for you. Even if the soil around the pipes get cold,
they might not get much lower than freezing. At 32F, your system should work very well.
With a 25 SEER, it's got to be a real performer.
I'd been considering using two small wells with an open-loop water to air setup.
The water-to-air exchanger would sit right behind the air intake.
But, now.. I'm starting to think that just going to solar PV to power the Sanyo
during daylight hours might be the best place to invest my money and efforts.
