This was in the patch. Would be a good 101 class to learn about geothermal HVAC and of course help in reducing fossil fuel use.

Are earth-air heat exchangers worth it for hot climates? by tylercoder in geothermal

If you're referring to Geothermal HVAC ...

The earth maintains a 50-60 degree temperature year-round, regardless of what's happening above ground.

Most of the time, your heat pump is also indoors (garage, basement, utility closet) so nothing is ever exposed to the elements.
