Will a heat pump pay off in Selma, AL?
In Selma, the math is close enough that it comes down to how long you plan to stay. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Lower bills claw that back: about $273 saved annually, for a payback of roughly 12.8 years. Whether that's worth it in Selma depends on how many years you expect to own the place.
Why Selma's climate drives this number
1831 heating degree days pile up here every year, so Selma has a mild winter by US standards; the cooling side runs to 2421 cooling degree days, where summers are hot enough that cooling matters as much as heating. 21.2°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 14°F on file. Worked through the model, that's a seasonal COP of 3.21 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Selma sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, CRAIG FLD, 5.8 miles from Selma.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,444 kWh a year to keep it warm, plus cooling, for a combined electric bill near $583 a year. The gas furnace it replaces burns roughly 19 Mcf a year at 17.56 per Mcf here, for a running cost near $856 a year (electricity here runs 16.62¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 49.4 years, leaving the 15-year total $598 ahead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Selma — 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 $709 a year, which recovers the extra $8,000 spent going electric in roughly 11.3 years.
Selma against the rest of the country
Among 3206 cities, Selma's winter puts it at rank 2518 for severity, while its size puts it at rank 2267 for population — 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
What to do with this number in Selma
About 16,312 people live in Selma, Alabama, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
