Heat pump vs. gas furnace in Russellville, AL
Russellville sits right on the fence — how long you'll own the house decides this one. $3,500 is what Russellville would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $237 saved annually, for a payback of roughly 14.8 years. Whether that's worth it in Russellville depends on how many years you expect to own the place.
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 record low of 2.7°F on file. Worked through the model, that's a seasonal COP of 2.98 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Russellville — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. 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 its running cost near $865 a year, against 16.62¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 57 years; over 15 years the net position sits $55 ahead.
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 $8,000 spent going electric in roughly 8.8 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

Ask a local HVAC contractor for a quote before committing either way.
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.
