Waycross, GA: the heat pump payback math
In Waycross, a heat pump pays for itself within a reasonable window. $1,000 is what Waycross 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 $301 of lower running costs every year, landing the payback clock at roughly 3.3 years. That's a real payback, built from Waycross's own climate and utility rates, not a national guess.
The climate behind Waycross's payback figure
Waycross barely has a winter to speak of — 1273 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 2920 cooling degree days. 25.5°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 24.8°F on file. Worked through the model, that's a seasonal COP of 2.96 on the standard unit fit for this climate. A standard ducted system is enough here; Waycross's design temperature doesn't justify the cold-climate premium. Source: NOAA station WAYCROSS-WARE CO.

The month-to-month numbers for Waycross
Electricity use for heating alone comes out to about 1,089 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $533 a year. The gas furnace it replaces burns roughly 13 Mcf a year at 20.42 per Mcf here, for a running cost near $835 a year (electricity here runs 14.90¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 36.5 years, for a 15-year net position $3,521 ahead.
If your home heats with electric baseboard instead of gas
Not every home in Waycross has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $511 a year, which recovers the extra $5,500 spent going electric in roughly 10.8 years.
How Waycross compares nationally
Ranked against the other 3206 cities covered, Waycross comes in at 2768 for heating severity — 1 would be the coldest place in the dataset — and 2563 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.
