Heat Pump vs Furnace Cost: 2026 Price & Running Cost

Heat pump or furnace — which one costs less? Upfront, they’re closer than you’d expect — a ducted heat pump runs $8,000–$15,000 installed versus $9,000–$14,000 for a furnace plus central AC. On running costs, there’s no single winner: at 2025 US-average energy prices, a heat pump only beats a modern gas furnace when it averages a COP of about 3.4 or better — which happens in mild climates, not in a Minnesota winter.

Quick Answer: What Each Option Costs to Install

Your situation	Typical installed cost (2026)
Gas furnace only (keep your existing AC)	$3,500–$7,500
Gas furnace + new central AC	$9,000–$14,000
Ducted air-source heat pump (heating + cooling, one system)	$8,000–$15,000
Dual-fuel system (heat pump + gas furnace backup)	$10,000–$18,000
Ductless mini-split heat pump (whole home, multi-zone)	$8,000–$16,000
Geothermal heat pump	$20,000–$40,000+

These ranges come from our full pricing guides for heat pump installation cost and furnace replacement cost. Compare like with like: a furnace alone is heat only, so the fair fight is furnace + AC versus heat pump — and there the prices overlap almost completely.

Running Costs: The Honest Math

Most comparisons are rigged — heat pump advocates quote 47°F efficiency as a winter average, furnace advocates quote worst-case backup-strip heat as normal. Here is the calculation run fairly. Inputs (US Energy Information Administration, 2025): US-average electricity 17.3¢/kWh, natural gas $14.50/Mcf. COP is a heat pump’s efficiency — COP 3.0 delivers 3 units of heat per unit of electricity; a 95% AFUE furnace turns 95% of its fuel into heat.

Cost to deliver 100,000 BTU of heat, at US-average prices:

Heating method	Cost per 100,000 BTU delivered
Gas furnace, 98% AFUE	$1.43
Gas furnace, 95% AFUE	$1.47
Heat pump at COP 3.5 (mild weather, ~47°F)	$1.45
Heat pump at COP 3.0 (cool weather, ~35–40°F)	$1.69
Old gas furnace, 80% AFUE	$1.75
Heat pump at COP 2.5 (cold weather, ~25–30°F)	$2.03
Heat pump at COP 2.0 (deep cold, ~10–17°F)	$2.54
Cold-climate heat pump at COP 1.75 (around 5°F)	$2.90
Electric resistance / backup strips (COP 1.0)	$5.07

• On a mild day, the heat pump wins — at COP 3.5 it slightly beats a new 95% gas furnace.
• As temperatures fall, the lines cross around COP 3.4; below that, gas stays ahead through deep cold.
• Backup strips are the budget-killer, not the heat pump itself — at $5.07 per 100,000 BTU, resistance heat costs 3.4× what gas costs.

COP falls as it gets colder — physics, not a defect: the colder the air, the less heat there is to move. Typical inverter heat pumps run COP 3.5–4.5 at 47°F and 2.5–3.2 at 32°F; cold-climate models hold 1.75–2.5 at 5°F (ENERGY STAR’s cold-climate floor: COP ≥ 1.75 at 5°F, ≥70% capacity retained). Seasonal averages run around 2.0–2.5 in cold states and 3.0 in mild ones.

Break-even COP — what a heat pump must average to tie a 95% gas furnace: US average ≈ 3.4 (mild climates only) · Minnesota ≈ 4.2 (cheap gas at $10.98/Mcf makes it nearly impossible) · Georgia ≈ 2.1 (pricey gas at $20.42/Mcf, so the heat pump wins most of the season). Both “heat pumps are cheaper” and “gas is cheaper” are true — in different zip codes.

15-Year Total Cost: Two Worked Examples

Installed cost plus 15 years of heating energy and routine maintenance, at each state’s EIA 2025 prices (cooling excluded from both sides; prices held flat).

• Cold state — Minnesota (electricity 15.83¢/kWh, gas $10.98/Mcf; 2,000 sq ft home, ~90 million BTU/year, heat pump seasonal COP 2.2): gas furnace + AC ≈ $31,000 vs cold-climate heat pump ≈ $43,300 (dual fuel ≈ $40,300). Verdict: with a gas line, a furnace or dual fuel is cheaper — the heat pump still wins against propane, oil, or electric baseboards.
• Mild state — Georgia (electricity 14.74¢/kWh, gas $20.42/Mcf; ~35 million BTU/year, heat pump seasonal COP 3.0): heat pump ≈ $22,400 vs gas furnace + AC ≈ $26,900. Verdict: the heat pump wins by roughly $4,500 — mild winters, expensive delivered gas, one system to maintain.

Dual Fuel: The Cold-Climate Compromise

A dual-fuel (hybrid) system pairs a heat pump with a gas furnace under one thermostat: the heat pump heats while it’s cheaper — down to a 25–40°F switchover — and the furnace takes over below that, so backup strips never run. From our heat pump installation guide, dual-fuel systems run $10,000–$18,000 installed — priciest upfront, but in the Minnesota example it beats a heat-pump-only setup by about $3,000 over 15 years. Best fit: cold, gas-served homes replacing both systems anyway.

Incentives in 2026: Read This Before Trusting Any Quote

If a website or salesperson pitches you a “$2,000 federal tax credit” for a heat pump, that claim is out of date — the federal Section 25C credit (30% of cost, up to $2,000 for heat pumps, $600 for high-efficiency furnaces) ended on December 31, 2025. What still exists: state and utility rebates, commonly $200–$1,000 for a 97%+ AFUE furnace and $500–$2,000+ for qualifying heat pumps — verify yours at dsireusa.org. Our furnace replacement guide tracks the same post-2025 reality.

In Canada

The same math applies, amplified: in gas-served Prairie and southern-Ontario homes, a gas furnace or dual-fuel hybrid usually costs least, while heat pumps clearly win against oil, propane, and electric baseboards — still common in Atlantic Canada and rural areas. Installed prices in CAD (FurnacePrices.ca, 2026; not converted from USD): standard ducted heat pump C$7,000–$12,000; cold-climate ducted C$12,000–$18,000+. The Canada Greener Homes Loan closed in fall 2025 — check current provincial and utility rebates before budgeting around one.

So, Which Should You Choose?

• Choose a heat pump if: you’re in climate zones 3–5; your delivered gas is expensive or you have no gas line; you’re replacing furnace and AC together; you’re coming off oil, propane, or baseboards; or your electricity is cheap (under ~15¢/kWh). Leaky ducts tax a heat pump more than a furnace.
• Choose a gas furnace if: you’re in zone 6–7 with pipeline gas under ~$13/Mcf; your AC is young and only the furnace died; or your electricity is expensive (20¢+/kWh) while gas is cheap.
• Choose dual fuel if: you’re cold-climate and gas-served, replacing both systems anyway, and want the lowest-risk winter bills rather than the lowest possible price.
• Either way: get a Manual J load calculation before signing. An oversized furnace short-cycles; an undersized heat pump lives on its backup strips — both cost more than any brand choice.

Worked Example: Pricing One Winter of Heat

Take a home that needs 50 million BTU of delivered heat across a winter — between this guide’s Georgia model home (35 million BTU a year) and its Minnesota one (90 million). That’s 500 units of 100,000 BTU. Run it through the cost-per-100,000-BTU table above:

• Gas furnace, 95% AFUE: 500 × $1.47 = $735
• Heat pump averaging COP 3.0: 500 × $1.69 = $845
• Heat pump averaging COP 2.5: 500 × $2.03 = $1,015
• Electric backup strips (COP 1.0): 500 × $5.07 = $2,535

Same house, same winter: the heating bill more than triples between the best and worst rows, and the only thing that changed is the efficiency the equipment actually averages in your climate. That is why this guide keeps pointing at your local gas and electricity prices rather than national slogans.

Red Flags in a Heat Pump or Furnace Quote

• A dead tax credit in the pitch. The quote is built around the “$2,000 federal tax credit” for a heat pump — the Section 25C credit ended on December 31, 2025.
• Mild-day math sold as a winter average. Heat pump running costs quoted only at 47°F efficiency (COP 3.5) — the rigged comparison this guide warns about.
• Backup heat never mentioned. A cold-climate heat pump quote with no word on when the strips take over or what they cost to run.
• An unfair fight. A furnace-only price compared against a heat pump — without adding the new AC the furnace side also needs.
• No load calculation. Either system sized off the old unit’s label, with no Manual J — the sizing mistake this guide calls costlier than any brand choice.

Questions to Ask Before You Hire

• Is this comparison furnace + AC versus heat pump — or furnace alone?
• What seasonal COP are you assuming for the heat pump in my climate zone?
• Which state or utility rebates does this quote assume — and are they current?
• Will you run a Manual J load calculation before sizing the system?
• At what outdoor temperature does backup heat take over in this setup — and what does it cost to run?

How Heating Costs Vary by Region

This whole guide is a regional argument, so the variation is the point. At US-average energy prices, a heat pump must average a COP of about 3.4 to tie a 95% gas furnace — mild-climate territory. In Minnesota, cheap gas ($10.98/Mcf) pushes the break-even to about 4.2, which no heat pump averages across a winter; in Georgia, pricey gas ($20.42/Mcf) drops it to about 2.1, so the heat pump wins most of the season. Canada amplifies the same split: gas-served Prairie and southern-Ontario homes usually lean furnace or dual fuel, while homes on oil, propane or electric baseboards — still common in Atlantic Canada and rural areas — lean heat pump almost everywhere.
