Orlando, FL: the heat pump payback math
In Orlando, a heat pump pays for itself within a reasonable window. 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). That premium is recovered through $311 of lower running costs every year, landing the payback clock at roughly 3.2 years. That's a real payback, built from Orlando's own climate and utility rates, not a national guess.
The climate behind Orlando's payback figure
Orlando barely has a winter to speak of — 414 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 3631 cooling degree days. Sizing runs off the design temperature, not the average day: 42.1°F here (record low 37.9°F), which works out to a seasonal COP of 3.45 for the standard class of unit this climate calls for. A standard ducted system is enough here; Orlando's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, ORLANDO INTERNATIONAL AIRPORT, 2.7 miles from Orlando.
The month-to-month numbers for Orlando
A 2000-square-foot house here would pull roughly 304 heating kilowatt-hours annually on top of cooling, totalling about $525 a year on electricity. That compares with roughly 4 Mcf a year of gas at Orlando's 25.48 per-Mcf rate — about $836 a year — against a local electricity rate of 15.43¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 35.3 years, leaving the 15-year total $3,671 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Orlando 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. About $363 a year comes back this way, enough that the 15.1-year payback clears the $5,500 premium comfortably within the equipment's life.
Orlando against the rest of the country
Among 3206 cities, Orlando's winter puts it at rank 3078 for severity, while its size puts it at rank 58 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.

About 334,854 people live in Orlando, Florida, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, it's worth getting quotes before your current system fails, not after.
Ask a local HVAC contractor for a quote before committing either way.
