Boaz, AL: the heat pump payback math
This one's marginal in Boaz: it only clears if you stay long enough. $3,500 is what Boaz 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. That premium is recovered through $240 of lower running costs every year, landing the payback clock at roughly 14.6 years. Whether that's worth it in Boaz depends on how many years you expect to own the place.
Why Boaz's climate drives this number
2565 heating degree days pile up here every year, so Boaz has a mild winter by US standards; the cooling side runs to 1706 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: 14°F here (record low 8.6°F), which works out to a seasonal COP of 3.04 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Boaz — 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 THE ALBERTVILLE MUNI ARPT-THO, the closest NOAA station, 6.1 miles out.
The month-to-month numbers for Boaz
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,136 kWh a year to keep it warm, plus cooling, for a combined electric bill near $597 a year. That compares with roughly 27 Mcf a year of gas at Boaz's 17.56 per-Mcf rate — about $837 a year — against a local electricity rate of 16.62¢/kWh. Buy it outright, not incrementally, and payback stretches to 56.3 years; over 15 years the net position sits $96 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Boaz heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $850 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 9.4 years.
Where Boaz ranks in this dataset
Among 3206 cities, Boaz's winter puts it at rank 2120 for severity, while its size puts it at rank 3094 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
