The average American household spends $2,200 per year on energy. Choosing between a heat pump and a gas furnace is a decision that affects your bills for 15–20 years. We analyzed utility rates, equipment costs, and climate data for 25 U.S. cities to answer one question: which system costs less over a decade?
The Quick Answer
In most of the United States, a heat pump costs $1,200–$3,800 less over 10 years than a gas furnace when you factor in equipment, installation, energy, and maintenance. The advantage is largest in the South and West. In the coldest regions (Minnesota, North Dakota), a dual-fuel system (heat pump + gas backup) is optimal.
| Region | 10-Year Gas Furnace Cost | 10-Year Heat Pump Cost | Heat Pump Savings |
|---|---|---|---|
| Southeast (FL, GA, AL) | $9,200 | $5,800 | $3,400 saved |
| Southwest (AZ, NV, TX) | $8,900 | $5,900 | $3,000 saved |
| Mid-Atlantic (VA, MD, PA) | $10,500 | $7,800 | $2,700 saved |
| Midwest (IL, OH, IN) | $11,200 | $9,100 | $2,100 saved |
| Northeast (NY, MA, CT) | $12,800 | $10,500 | $2,300 saved |
| Upper Midwest (MN, WI) | $11,500 | $11,800 | -$300 (dual-fuel recommended) |
10-year costs include equipment + installation + annual energy + maintenance for a 2,000 sq ft home. Utility rates as of Q1 2026.
How We Calculated the 10-Year Costs
For each of the 25 cities in our analysis, we used:
- Equipment cost: Median quotes from our contractor network for a 3-ton air-source heat pump vs a 95% AFUE gas furnace with 13 SEER AC
- Installation cost: Local labor rates × estimated hours per installation type
- Energy cost: Heating degree days × system efficiency (HSPF for heat pump, AFUE for gas) × local utility rates (EIA data)
- Maintenance: $150/year for gas furnace (annual inspection recommended), $100/year for heat pump
Federal tax credit of $2,000 applied to heat pump cost. State rebates not included.
Where Gas Furnaces Still Win
Gas makes economic sense in three situations:
- Extremely cold climates — Where temperatures regularly drop below 0°F. Older heat pumps struggled here. New cold-climate models (discussed below) are changing the equation.
- Very low natural gas prices — In states like Oklahoma and Louisiana, natural gas costs $0.60–$0.80 per therm. At those rates, the operating cost advantage of a heat pump shrinks.
- Existing gas infrastructure — If your home already has a gas line and ductwork sized for a furnace, switching to a heat pump may require electrical panel upgrades ($1,500–$3,000) that tip the 10-year math.
The Technology Factor: Cold-Climate Heat Pumps
Modern cold-climate heat pumps (CC-ASHPs) maintain full capacity at 5°F and continue operating at -15°F. Models from Mitsubishi (Hyper Heat), Carrier (Greenspeed), and Lennox (SL25XPV) have COP ratings above 2.0 at 5°F — meaning they still deliver twice the heat output per unit of electricity consumed, even in sub-freezing conditions.
For homes in the Upper Midwest, a cold-climate heat pump with electric resistance backup strips costs about the same over 10 years as a gas furnace, but offers the advantage of zero on-site carbon emissions and eligibility for additional utility rebates (up to $4,000 in Minnesota through Xcel Energy's heat pump program in 2026).
Environmental Comparison
| Metric | Gas Furnace (95% AFUE) | Heat Pump (8.5 HSPF) |
|---|---|---|
| Annual CO2 emissions (2,000 sq ft home) | 6,200 lbs | 1,800–3,400 lbs (depends on grid mix) |
| On-site emissions | Yes (combustion) | Zero |
| Refrigerant global warming potential | N/A | R-410A: 2,088 GWP (R-32: 675 GWP in newer models) |
Bottom Line: Which Should You Choose?
Choose a heat pump if: You live in a climate with mild to moderate winters (zones 1–5), your electricity rate is below $0.16/kWh, you want both heating and cooling from one system, or you plan to stay in your home 7+ years. Get 3 local quotes.
Consider a gas furnace if: You live in climate zones 6–7 with natural gas below $0.90/therm, your home already has gas infrastructure you plan to keep, or you plan to sell within 3 years (lower upfront cost).
Consider a dual-fuel system if: You live in climate zones 5–7, want the efficiency of a heat pump for mild days with the reliability of gas for extreme cold. Dual-fuel typically adds $800–$1,500 to installation cost but provides the best of both technologies.
