Is a heat pump cheaper than gas in Maine?
Northeast · Very cold (e.g. northern New England, Mountain West, Upper Plains) · EIA residential fuel prices
For a reference 2,000 sq ft home in Maine (assumed seasonal COP 2, 95% gas furnace), a heat pump costs about $3,154/year to run versus about $1,254/year for natural gas — so a heat pump is about $1,900/yr more than a gas furnace. It is cheaper than propane ($3,400/yr), cheaper than heating oil ($3,601/yr), and far cheaper than electric resistance ($6,308/yr). The cheapest option here is natural gas furnace (95% afue). These are estimates — verify with an HVAC pro.

| Fuel | Residential price | Source / period |
|---|---|---|
| Electricity (residential) | 28.32¢/kWh | EIA, March 2026 |
| Natural gas (residential) | $1.567/therm (US avg) | EIA, March 2026 |

EIA did not publish a March 2026 residential natural-gas price for Maine; the U.S. average of $16.25/Mcf is used and flagged. Heating oil and propane are EIA residential prices for New England (PADD 1A) (Week ending 2026-03-30) — EIA does not publish these per individual state.
Annual heating cost in Maine — every system compared
Reference: a 2,000 sq ft home in a very cold (e.g. northern new england, mountain west, upper plains), roughly 76 MMBTU/year of useful heat. Energy cost only (no equipment, install or maintenance):
| Heating system | Annual energy cost | Annual use |
|---|---|---|
| Natural gas furnace (95% AFUE) | $1,254/yr | 800 therms |
| Heat pump | $3,154/yr | 11,137 kWh |
| Propane furnace (92% AFUE) | $3,400/yr | 903 gal |
| Heating oil (85% AFUE) | $3,601/yr | 646 gal |
| Electric resistance (baseboard, COP 1.0) | $6,308/yr | 22,274 kWh |

Frequently asked questions
Is a heat pump cheaper to run than gas in Maine?
Not in this reference case. For a 2,000 sq ft home in Maine (assumed seasonal COP 2, 95% gas furnace), a heat pump costs about $3,154/year vs about $1,254/year for gas, because Maine has relatively high electricity prices. A heat pump is still typically cheaper than propane, oil and electric resistance here.
What does it cost to heat a home in Maine?
Using EIA March 2026 prices and a 2,000 sq ft home in a very cold (e.g. northern new england, mountain west, upper plains) (about 76 MMBTU/yr), estimated annual energy cost is about: heat pump $3,154, natural gas $1,254, propane $3,400, heating oil $3,601, electric resistance $6,308. The cheapest here is natural gas furnace (95% afue).
Is a heat pump cheaper than propane or heating oil in Maine?
In this reference case, vs propane a heat pump saves about $246/year, and vs heating oil it saves about $447/year. Heat pumps usually beat both delivered fuels comfortably because they deliver far more heat per unit of energy.
How does Maine rank for heat-pump savings?
On heat-pump savings vs a gas furnace (reference 2,000 sq ft home), Maine ranks #50 of 51 states (1 = saves the most). This reflects Maine's mix of 28.32¢/kWh electricity and US-average gas.
