Fairhope, AL: the heat pump payback math
Fairhope clears a genuine payback here, inside a reasonable stretch of years. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. Fairhope's residents would see roughly $252 a year back in running costs, putting the payback around 4 years. That's a real payback, built from Fairhope's own climate and utility rates, not a national guess.
Why Fairhope's climate drives this number
Degree days tell the story here: Fairhope racks up 1470 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2560 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 27.3°F, against a record low of 18.1°F. That puts the seasonal coefficient of performance at 3.01 for the recommended standard unit. A standard ducted system is enough here; Fairhope's design temperature doesn't justify the cold-climate premium. These numbers come from FAIRHOPE 3 NE , the closest NOAA station, 1.9 miles out.
Fairhope's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 1,237 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $568 a year. That compares with roughly 15 Mcf a year of gas at Fairhope's 17.56 per-Mcf rate — about $820 a year — against a local electricity rate of 16.62¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 43.7 years, leaving the 15-year total $2,779 ahead.
The other scenario: no gas furnace to begin with
Not every home in Fairhope has gas service. Swap the comparison to resistance heat instead of gas, and Fairhope's answer improves. The saving here runs about $602 a year, which recovers the extra $5,500 spent going electric in roughly 9.1 years.
Fairhope against the rest of the country
Among 3206 cities, Fairhope's winter puts it at rank 2702 for severity, while its size puts it at rank 1539 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.
