Heat pump vs gas furnace in Georgia: heating cost by fuel (2026)

At Georgia's average prices, a heat pump (COP 2.5) delivers heat for $18.05 per million BTU, versus $19.69 for a 95% gas furnace, $36.97 for propane and $50.36 for heating oil. That makes the heat pump cheaper than a new gas furnace here. It breaks even with gas at a seasonal COP of 2.29.

Heat pump, est. per year$446COP 2.5; $558 at COP 2.0, $372 at COP 3.0

Gas furnace, est. per year$48795% AFUE; $578 at 80%

Propane, est. per year$914heat pump breaks even at COP 1.22

The Georgia inputs

Electricity: 15.40¢/kWh, residential average year-to-date through July 2026 (EIA Electric Power Monthly). U.S.: 18.19¢.
Natural gas: $19.38 per thousand cubic feet, average of EIA monthly residential prices for Oct 2025–Mar 2026 (6 months reported). U.S.: $15.60.
Propane: $3.21/gal, week of Oct 19, 2026 (a year earlier: $2.94); EIA state series. EIA weekly prices exclude taxes.
Heating oil: $5.93/gal, week of Oct 19, 2026 (a year earlier: $3.46); EIA regional average: Lower Atlantic (PADD 1C). Excludes taxes.
Climate: 2,473 heating degree days per year (base 65°F); NOAA CPC population-weighted state average, 2011–2025.

Defaults are the state's latest EIA prices and NOAA degree days; the BTU-per-degree-day, COP and efficiency values are our assumptions. Put in your own bill rates and a known annual heat use for a better answer. Runs in your browser; nothing is sent anywhere. Tip: 1 therm = 0.1 MMBtu; $/therm × 10.36 ≈ $/Mcf.

Assumptions (ours, not EIA/NOAA figures): heat pump seasonal COP 2.5 (we also show 2.0 for very cold climates and 3.0 for mild ones); gas furnace 95% AFUE (older units ~80%); propane furnace 95%; oil 85%; electric resistance 100%. Annual totals assume a home that needs 10,000 BTU of delivered heat per heating degree day, a round number for an existing house; a tight new home may need half that, a drafty one more. The per-MMBtu comparison does not depend on house size. Prices exclude equipment, installation, maintenance, fixed monthly utility charges and rebates. Method & sources.
