Wait, what's this "geothermal HVAC" you're talking about?
Nothing. It's ruined. We should replace it with a geothermal HVAC.
So? What do we need to fix the HVAC?
Geothermal HVAC-A geothermal heat pump or ground source heat pump is a central heating and/or cooling system that transfers heat to or from the ground. It uses the earth all the time, without any intermittency, as a heat source or a heat sink.
Don't worry! I'll draw out a diagram of how it works on my trusty notepad.
So, how exactly does this work? I still don't get it.
