Will a heat pump pay off in Prattville, AL?
This one's marginal in Prattville: it only clears if you stay long enough. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Prattville's residents would see roughly $293 a year back in running costs, putting the payback around 11.9 years. It's a genuine toss-up here — Prattville's numbers don't point clearly either way.
How cold Prattville actually gets
1685 heating degree days pile up here every year, so Prattville has a mild winter by US standards; the cooling side runs to 2745 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. Sizing runs off the design temperature, not the average day: 23.2°F here (record low 15.8°F), which works out to a seasonal COP of 3.26 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Prattville sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from MAXWELL AFB AIRPORT, the closest NOAA station, 7.4 miles out.
Prattville's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,309 kWh a year to keep it warm, plus cooling, for a combined electric bill near $607 a year. Prattville's gas rate of 17.56 per Mcf, applied to the 18 Mcf a year the furnace burns, puts its running cost near $899 a year, against 16.62¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 46.1 years; over 15 years the net position sits $894 ahead.
The other scenario: no gas furnace to begin with
Not every home in Prattville has gas service. Swap the comparison to resistance heat instead of gas, and Prattville's answer improves. About $694 a year comes back this way, enough that the 11.5-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Prattville ranks in this dataset
Ranked against the other 3206 cities covered, Prattville comes in at 2595 for heating severity — 1 would be the coldest place in the dataset — and 1028 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
