Kingsland, GA: the heat pump payback math
Kingsland clears a genuine payback here, inside a reasonable stretch of years. $1,000 is what Kingsland 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. Kingsland's residents would see roughly $289 a year back in running costs, putting the payback around 3.5 years. That's a real payback, built from Kingsland's own climate and utility rates, not a national guess.
Why Kingsland's climate drives this number
Kingsland barely has a winter to speak of — 1250 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 2693 cooling degree days. Sizing runs off the design temperature, not the average day: 28.6°F here (record low 27.1°F), which works out to a seasonal COP of 3.05 for the standard class of unit this climate calls for. A standard ducted system is enough here; Kingsland's design temperature doesn't justify the cold-climate premium.

The month-to-month numbers for Kingsland
A 2000-square-foot house here would pull roughly 1,038 heating kilowatt-hours annually on top of cooling, totalling about $497 a year on electricity. The gas furnace it replaces burns roughly 13 Mcf a year at 20.42 per Mcf here, for a running cost near $786 a year (electricity here runs 14.90¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 38 years, leaving the 15-year total $3,337 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Kingsland heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $495 a year, which recovers the extra $5,500 spent going electric in roughly 11.1 years.
Kingsland against the rest of the country
Among 3206 cities, Kingsland's winter puts it at rank 2783 for severity, while its size puts it at rank 1859 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.
