Residential comparison

Heat pump
vs. traditional HVAC.

Pick a heat pump and the system it would replace — gas furnace + AC, electric resistance, oil, or propane. We pull live electricity and fuel prices for your area, then calculate the true cost of both over your time horizon, plus the exact crossover year.

Sources: NREL/OEDI ZIP-to-utility lookup for likely utility identification; Texas PUC Power to Choose for the delivery utility in Texas retail-choice areas; OpenEI URDB for approved current-year residential tariff options when available; U.S. EIA latest monthly state residential averages when no qualified current-year utility tariff is available; EIA and NOAA for degree days and fuel prices; DOE, NEEP, ENERGY STAR, and manufacturer data for equipment specifications. Current-year tariff options use a time-weighted incremental energy charge and exclude fixed and demand charges. Utility matches indicate likely providers, not guaranteed service territories. Both alternatives are modeled as new systems using their selected nameplate efficiencies. Energy is modeled with a simplified degree-day method. See the full methodology.
