Heat Pump Payback in Miramar, FL
Heat pump vs. gas furnace in Miramar, FL
Miramar sits right on the fence, how long you'll own the house decides this one. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,000. That premium is recovered through $335 of lower running costs every year, landing the payback clock at roughly 9 years. Whether that's worth it in Miramar depends on how many years you expect to own the place.

The climate behind Miramar's payback figure
60 heating degree days pile up here every year, so Miramar barely has a winter to speak of; the cooling side runs to 4759 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 51.1°F, and the coldest daily reading in the 2024 station record was 48.9°F. That puts the seasonal coefficient of performance at 3.72 for the recommended standard unit. A standard ducted system is enough here; Miramar's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, Opa Locka Airport, 5.8 miles from Miramar.
What it actually costs to run, year to year
Heating hardly figures in Miramar: on a 2000-square-foot reference house the heat pump's roughly $632 yearly electric bill is nearly all cooling. With so little heating demand, a furnace in Miramar would burn only about 1 Mcf a year ($25.48 per Mcf); almost all of the $968 yearly running cost of the current system is cooling, at 15.43¢/kWh. Any saving here is really a cooling-efficiency saving. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $2,028 ahead.
What would change Miramar'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 Miramar at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $335 a year saved, a difference under $2,345 pays back within 7 years here, and under $3,350 within 10.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Miramar, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Miramar's answer improves. 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.
Where Miramar ranks in this dataset
Among 3206 cities, Miramar's winter puts it at rank 3166 for severity, while its size puts it at rank 196 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.
What to do with this number in Miramar
About 143,242 people live in Miramar, 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, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

More on how this number was built
Every constant behind this page, the 3.72 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Not every home in Miramar has gas; the guide comparing a heat pump against electric baseboard covers that case separately.
