Is a heat pump worth it in Hinesville?
This one's marginal in Hinesville: it only clears if you stay long enough. $3,500 is what Hinesville 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. Hinesville's residents would see roughly $309 a year back in running costs, putting the payback around 11.3 years. Whether that's worth it in Hinesville depends on how many years you expect to own the place.
The climate behind Hinesville's payback figure
Hinesville has a mild winter by US standards — 1529 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 2402 cooling degree days. Sizing runs off the design temperature, not the average day: 24.4°F here (record low 22.1°F), which works out to a seasonal COP of 3.29 for the cold-climate class of unit this climate calls for. Hinesville needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

The month-to-month numbers for Hinesville
A 2000-square-foot house here would pull roughly 1,177 heating kilowatt-hours annually on top of cooling, totalling about $480 a year on electricity. The gas furnace it replaces burns roughly 16 Mcf a year at 20.42 per Mcf here, for a running cost near $789 a year (electricity here runs 14.90¢/kWh). Buy it outright, not incrementally, and payback stretches to 43.8 years; over 15 years the net position sits $1,128 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Hinesville 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 $560 a year, which recovers the extra $8,000 spent going electric in roughly 14.3 years.

Where Hinesville's figure comes from
The methodology guide walks through exactly how Hinesville's 3.29 seasonal COP and the rest of this page's numbers get built. Hinesville's 24.4°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
