Will a heat pump pay off in Florence, AL?
This one's marginal in Florence: it only clears if you stay long enough. $3,500 is what Florence 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. Florence's residents would see roughly $249 a year back in running costs, putting the payback around 14 years. Whether that's worth it in Florence depends on how many years you expect to own the place.
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, against a record low of 0°F. That puts the seasonal coefficient of performance at 2.97 for the recommended cold-climate unit. A cold-climate unit is the right call in Florence — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. 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 (electricity here runs 16.62¢/kWh). Buy it outright, not incrementally, and payback stretches to 54.1 years; over 15 years the net position sits $242 ahead.
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 $8,000 spent going electric in roughly 9.1 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.
