Heat Pump Payback in Florence, AL
Will a heat pump pay off in Florence, AL?
The payback math works in Florence on paper, past the equipment's own working life. $5,500 is what Florence would pay extra to go electric rather than replace the furnace and AC with the same again. Florence's residents would see roughly $249 a year back in running costs, putting the payback around 22 years. Florence's own numbers say this pencils out only in theory, not in practice.

Why Florence's climate drives this number
Florence has a mild winter by US standards, 2644 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1908 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 11.3°F, and the coldest daily reading in the 2024 station record was 0°F. That puts the seasonal coefficient of performance at 2.97 for the recommended cold-climate unit. The average winter here is gentle, but sizing follows the cold snaps, and 11.3°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 Florence. Climate figures trace to the nearest NOAA station, Muscle Shoals 2 N, 4.1 miles from Florence.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,254 kWh a year to keep it warm, plus cooling, for a combined electric bill near $645 a year. The gas furnace it replaces burns roughly 28 Mcf a year at $17.56 per Mcf here, for a running cost near $895 a year including the old AC (electricity here runs 16.62¢/kWh). 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 $1,758 behind.
How sensitive Florence's result is to prices
This result holds unless electricity climbs above 34.3¢/kWh (it is 16.62¢ now) or gas drops below $8.50 per Mcf (now $17.56); past either point, gas becomes the cheaper fuel in Florence. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $249 a year saved, a difference under $1,743 pays back within 7 years here, and under $2,490 within 10.
The other scenario: no gas furnace to begin with
Gas isn't universal in Florence, many houses run on electric heat already. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $879 a year, which recovers the extra $10,000 spent going electric in roughly 11.4 years.
Where Florence ranks in this dataset
Among 3206 cities, Florence's winter puts it at rank 2069 for severity, while its size puts it at rank 966 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
