Whether a heat pump or a gas furnace costs less for you genuinely depends on three things: your local electricity and gas prices, how cold your winters get, and your home itself. Published 2026 figures give wide ranges — a ducted heat pump commonly cited around $12,000–$18,000 installed and a gas furnace around $5,000–$9,000 — but the gap narrows when you compare a heat pump against a furnace plus AC. This page lays out the factors honestly instead of declaring a single winner.

There's no universal answer — the right choice depends on your fuel prices, climate, and home. These are the levers. All figures are published ranges that vary by home and location; get a professional quote.
Published 2026 figures put a ducted heat pump around $12,000–$18,000 installed and a gas furnace around $5,000–$9,000. But if you'd otherwise buy a furnace plus a separate AC, the cost gap against a heat pump (which does both) narrows considerably.
Best for: Comparing like-for-like — heat pump vs. furnace plus AC.
The catch: A furnace alone looks cheaper until you add the AC you'd also need for cooling.
Operating cost hinges on the price gap between electricity and gas in your area. A common benchmark: if your electricity price per equivalent heat unit is below a few times your gas price, a heat pump tends to win on running cost.
Best for: Areas with relatively cheap electricity or expensive gas.
The catch: Where electricity is very expensive relative to gas, a furnace may run cheaper.
Heat pump efficiency varies with outdoor temperature. Modern cold-climate models work well in deep cold, but very cold regions may need a back-up heat source or a dual-fuel setup.
Best for: Mild and moderate climates — and cold-climate models in harsh ones.
The catch: In extreme cold, you may need backup heat, which adds cost and complexity.
Heat pumps move heat rather than burn fuel, so they deliver more heat energy than the electricity they use — published figures cite well over 200% effective efficiency versus roughly 90–96% for a gas furnace. That efficiency is what can lower running costs.
Best for: Lowering operating cost where electricity prices are reasonable.
The catch: High efficiency doesn't help if local electricity is priced very high.
A heat pump heats and cools with one system. If you need air conditioning anyway, a heat pump can replace both a furnace and an AC unit, changing the total-cost comparison.
Best for: Homes that need both heating and cooling.
The catch: If you truly never need cooling, the heat pump's dual-purpose advantage shrinks.
Some states, utilities, and municipalities offer heat pump rebates that can offset the higher upfront cost. These vary enormously by location and change over time.
Best for: Homeowners in areas with strong heat pump rebate programs.
The catch: Rebate availability and amounts vary widely — confirm current local programs.
The federal Energy Efficient Home Improvement Credit (Section 25C), which offered up to $2,000 for qualifying heat pumps, expired on December 31, 2025. Heat pumps installed in 2026 generally don't qualify for that federal credit, though state and utility incentives may still apply.
Best for: Budgeting 2026 projects with current rules.
The catch: Many guides still quote the expired $2,000 federal credit — verify before budgeting.
A well-sealed, well-insulated home with good ducts gets the most from either system. Poor insulation raises running costs no matter which heating system you choose.
Best for: Homes that have addressed air-sealing and insulation first.
The catch: A leaky home can undercut a heat pump's efficiency advantage — fix the envelope first.
