Heat Pump Payback in Russellville, AL
Heat pump vs. gas furnace in Russellville, AL
Russellville technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Russellville would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $237 saved annually, for a payback of roughly 23.2 years. Russellville's own numbers say this pencils out only in theory, not in practice.

The climate behind Russellville's payback figure
2813 heating degree days pile up here every year, so Russellville has a mild winter by US standards; the cooling side runs to 1626 cooling degree days, where summers are hot enough that cooling matters as much as heating. 11.8°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 2.7°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.98 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 11.8°F is below the 25°F point where a standard unit leans on resistance backup, so a cold-climate unit is what gets priced for Russellville. These numbers come from Russellville 4 Sse, the closest NOAA station, 3.7 miles out.
Russellville's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,390 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $628 a year. Russellville's gas rate of $17.56 per Mcf, applied to the 29 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $865 a year, against 16.62¢ per kWh for electricity. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,945 behind.
What would change Russellville's answer
This result holds unless electricity climbs above 30.8¢/kWh (it is 16.62¢ now) or gas drops below $9.47 per Mcf (now $17.56); past either point, gas becomes the cheaper fuel in Russellville. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $237 a year saved, a difference under $1,659 pays back within 7 years here, and under $2,370 within 10.
Electric resistance heat in Russellville, compared
Plenty of homes in Russellville heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Russellville's answer improves. The saving here runs about $906 a year, which recovers the extra $10,000 spent going electric in roughly 11 years.
How Russellville compares nationally
Among 3206 cities, Russellville's winter puts it at rank 1988 for severity, while its size puts it at rank 3043 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
What to do with this number in Russellville

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Russellville's 2.98 seasonal COP and payback figure. Russellville's 11.8°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
