[Greenbuilding] Geothermal a/c

[natural building]

Semantics perhaps, but I believe you are talking about 'Ground Source' or 'Water Source' or 'Air Source' heat pump systems.
My understanding is that 'Geothermal' is a system that taps into underground heat sources such as steam or even volcanic heat sources...

Cheers, Steve.

I just went up to our attic and it's 80*. The house is maintaining a very comfortable level of conditioning, and not burning a great deal of KWs.
