Geothermal Comparisons

Neither is universally better. Compare the home’s heating and cooling loads, current-model capacity and efficiency at local design conditions, backup heat, distribution, electrical and site work, complete bids, service, and expected ownership period.

Compare only the exact current models offered for the home. Require capacity and efficiency at the same ground-loop conditions, matched components, controls, warranty certificates, installer qualifications, commissioning, parts access, and local service support.

Yes, but they must be designed and priced separately. Model the heat pump’s annual electricity use, the solar system’s site-specific production, utility rates, interconnection, roof and ground needs, financing, and only those incentives confirmed in writing. Do not assume a zero bill or automatic program stacking.

A geothermal proposal includes an underground heat exchanger or groundwater system in addition to indoor heating and cooling equipment. Design, drilling or trenching, access, ground conditions, permits, distribution, electrical work, controls, restoration, and commissioning all affect cost. Compare complete written scopes and property-specific energy models rather than a national price or savings promise.
