Heat Pump Payback in Sunrise, FL
Will a heat pump pay off in Sunrise, FL?
This one's marginal in Sunrise: it only clears if you stay long enough. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. That premium is recovered through $352 of lower running costs every year, landing the payback clock at roughly 8.5 years. Whether that's worth it in Sunrise depends on how many years you expect to own the place.

Why Sunrise's climate drives this number
Sunrise barely has a winter to speak of, 65 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 4997 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 50°F, and the coldest daily reading in the 2024 station record was 48.9°F. That puts the seasonal coefficient of performance at 3.69 for the recommended standard unit. A standard ducted system is enough here; Sunrise's design temperature doesn't justify the cold-climate premium. These numbers come from Ft Lauder Executive Airport, the closest NOAA station, 5.9 miles out.
Sunrise's running-cost comparison, in dollars
Heating hardly figures in Sunrise: on a 2000-square-foot reference house the heat pump's roughly $664 yearly electric bill is nearly all cooling. With so little heating demand, a furnace in Sunrise would burn only about 1 Mcf a year ($25.48 per Mcf); almost all of the $1,017 yearly running cost of the current system is cooling, at 15.43¢/kWh. Any saving here is really a cooling-efficiency saving. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $2,283 ahead.
What would change Sunrise's answer
Because the heat pump's better air conditioning saves more electricity than its heating uses, it stays cheaper to run than the current furnace and AC in Sunrise at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $352 a year saved, a difference under $2,464 pays back within 7 years here, and under $3,520 within 10.
Electric resistance heat in Sunrise, compared
Not every home in Sunrise has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Even against resistance heat, the running-cost gap here isn't enough to clear the $7,500 incremental cost within the equipment's 15-year life.
How Sunrise compares nationally
Among 3206 cities, Sunrise's winter puts it at rank 3157 for severity, while its size puts it at rank 342 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.
