The four components of geothermal heating and cooling systems include the outdoor loop field, the indoor heat pump unit, the thermostat, and the ductwork that delivers the conditioned air. A geothermal heat pump has no parts exposed to the outdoor air, unlike air-source heat pumps, whose condensing unit sits outdoors. Much of the indoor unit in a geothermal system contains the parts that would otherwise be exposed to the weather year-round.
