Is it worth converting from oil heat to a heat pump?

Oil-to-heat-pump conversion is still the strongest 2026 energy-upgrade ROI in the Northeast, though the stack shrank when the federal 25C credit expired Dec 31, 2025: HEEHRA point-of-sale up to $8,000 (income-qualified) + state credits $300–$1,500 + utility rebates $1,500–$4,000 (MA, CT, RI, NY, ME, NH) can still reach ~$12,000. Operating cost drops 40–60% — oil at $4.50/gallon in 2026 costs roughly 2× a cold-climate heat pump running on electricity at $0.22/kWh. Payback is 5–9 years at non-income-qualified incentive levels. Pair the conversion with attic insulation for the best overall envelope economics.
