Niceville, FL: the heat pump payback math
In Niceville, a heat pump is the cheaper choice, and not by a little. 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. That premium is recovered through $385 of lower running costs every year, landing the payback clock at roughly 2.6 years. Nothing about that conclusion is generic — it's built entirely from Niceville's own numbers.
Why Niceville's climate drives this number
Niceville barely has a winter to speak of — 1169 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 3256 cooling degree days. Sizing runs off the design temperature, not the average day: 29.5°F here (record low 20.5°F), which works out to a seasonal COP of 3.08 for the standard class of unit this climate calls for. A standard ducted system is enough here; Niceville's design temperature doesn't justify the cold-climate premium.

The month-to-month numbers for Niceville
A 2000-square-foot house here would pull roughly 961 heating kilowatt-hours annually on top of cooling, totalling about $577 a year on electricity. Niceville's gas rate of 25.48 per Mcf, applied to the 12 Mcf a year the furnace burns, puts its running cost near $961 a year, against 15.43¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 28.6 years, for a 15-year net position $4,770 ahead.
Electric resistance heat in Niceville, compared
Not every home in Niceville 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 $531 a year, which recovers the extra $5,500 spent going electric in roughly 10.4 years.
Niceville against the rest of the country
Niceville lands at position 2807 out of 3206 cities on heating severity (coldest is 1), and 2105 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
