We were taught to steer clear of what we didn’t understand: refrigeration, flex duct, and mobile homes. Geothermal joined that club because no one slowed down to explain it. Avoidance isn’t laziness, a lot of time, it’s survival.

Geothermal swaps three things, all on the condenser portion: air for water, condenser fans for water pumps, and condenser for heat exchangers. It’s not black magic; it’s a heat pump with new accessories. You don’t fix geothermal by knowing everything—you fix it by knowing what should happen and spotting what didn’t. Voltage still matters. Compressor amps still matter; airflow still matters, but now water flow matters. If it’s a puzzle, we already know how to solve it—we just haven’t seen all the pieces yet.

The biggest disservice we do is gatekeeping geothermal through design docs and jargon. When the field tech or owner can’t see the logic, they opt out. We’re here to build that bridge with clarity. Let’s bring it back to what we know for sure. Blower airflow, high head pressure, locked rotor amps, voltage issues, bad capacitors, etc., we know and can fix. With what we have found out today, ground loops become another heat exchanger. Water pumps become condenser fans. Heat exchangers become an outdoor coil. If it isn’t on the condenser side, then it’s probably not a water problem. It is probably something you fixed before on another heat pump or air conditioner.
