For a typical 38 million-BTU heating season in District of Columbia: a 95% AFUE gas furnace costs about $686/year; a modern heat pump (HSPF 8.5) costs about $1122/year. Gas wins by $436/year at current local prices.

Heating fuel	Energy used/yr	Cost/yr
Natural gas (95% AFUE furnace) at $18.01/Mcf	395 therms	$686
Heat pump (HSPF 8.5, COP 2.49) at 25.41¢/kWh	4,416 kWh	$1122

District of Columbia: gas $18.01/Mcf (March 2026), electricity 25.41¢/kWh (April 2026). Climate: cool.

What this means in District of Columbia

At current District of Columbia prices, a gas furnace remains cheaper to run than a heat pump — $436/year less. The gap closes (and often flips) if electricity rates fall, gas prices rise, or you switch to a more efficient cold-climate heat pump. Heat pumps still win on flexibility: they cool in summer, qualify for the 30% federal tax credit, and decouple your heating from fossil fuels.

The gas vs heat-pump trade-off depends on three local numbers: gas price (18.01 $/Mcf here), electricity rate (25.41¢/kWh), and how cold winters get (climate: cool → effective HSPF 8.5).

How we calculated this

Gas furnace cost = (38 MMBtu) ÷ (95.00% efficient × 100,000 BTU/therm) × $1.737/therm.

Heat pump cost = (38 MMBtu) ÷ (2.49 COP × 3,412 BTU/kWh) × 25.41¢/kWh.

Heat load assumption: 38 MMBtu/year is typical for an 1,800 sqft home in a cool climate. Modify with your actual annual gas usage (from your bill) for a personalized answer.

FAQ

Does this account for cold-climate performance?

Yes — we use a state-specific effective HSPF (8.5 for District of Columbia) reflecting how heat pumps actually perform across the heating season at typical local outdoor temperatures.

What about my actual gas usage instead of these defaults?

Take your last 12 gas bills, sum the therms, and multiply by $1.737/therm. Compare to (your gas therms × 29.3 kWh) ÷ 2.49 × 0.2541 for what a heat pump would cost.

Are gas prices stable?

Less stable than electricity. Wholesale gas can swing 30%+ in a cold winter. The breakeven above can flip year-to-year depending on weather and pipeline conditions.
