Heat pump or central AC + furnace — which is better in 2026?

For most US homeowners in 2026, heat pump wins on total cost of ownership once you factor in the 30% federal 25C credit (capped $2,000/year for heat pumps specifically). Modern cold-climate heat pumps (Mitsubishi Hyperheat, Daikin VRV, Bosch IDS) maintain 100% rated capacity down to 5°F and 70–80% capacity below -10°F, so they're a viable single-system replacement in all but the coldest northern climates. Stack the federal 25C ($2K) + state credits + utility rebates ($1,500–$4,000 in MA/CT/RI/NY/CA) + HEEHRA $8K for income-qualified households and a heat-pump conversion often costs less net than a like-for-like AC + furnace.
