Purchase & financing

Cash vs. loan changes the true cost by thousands. Interest paid over the loan is a real ownership expense — most heat pumps are financed through a contractor or HELOC.

Sources: U.S. EIA (electricity rates), EIA/NOAA (heating & cooling degree days), DOE/NEEP/ENERGY STAR (equipment specs), Heatpump Economics curated incentive data. Energy use is modeled with a simplified degree-day method: annual load = design-load capacity × degree-days × 24 ÷ design temperature difference, split between the heat pump's compressor (at its estimated seasonal COP) and electric-resistance backup for the coldest hours below the unit's balance point. This is directionally accurate for comparing systems but is not a substitute for a contractor's Manual J load calculation. See the full methodology for formulas and citations.
