Heat pump vs. gas furnace in Fort Walton Beach, FL
In Fort Walton Beach, a heat pump is the cheaper choice, and not by a little. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). Fort Walton Beach's residents would see roughly $379 a year back in running costs, putting the payback around 2.6 years. Nothing about that conclusion is generic — it's built entirely from Fort Walton Beach's own numbers.
Why Fort Walton Beach's climate drives this number
Fort Walton Beach barely has a winter to speak of — 1173 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 3166 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 29.5°F, against a record low of 20.3°F. That puts the seasonal coefficient of performance at 3.08 for the recommended standard unit. A standard ducted system is enough here; Fort Walton Beach's design temperature doesn't justify the cold-climate premium.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 964 heating kilowatt-hours annually on top of cooling, totalling about $565 a year on electricity. That compares with roughly 12 Mcf a year of gas at Fort Walton Beach's 25.48 per-Mcf rate — about $944 a year — against a local electricity rate of 15.43¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 29 years, for a 15-year net position $4,686 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Fort Walton Beach 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 $526 a year, which recovers the extra $5,500 spent going electric in roughly 10.5 years.
Where Fort Walton Beach ranks in this dataset
