Heat Pump Payback in Homestead, FL
Will a heat pump pay off in Homestead, FL?
This one's marginal in Homestead: 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. Homestead's residents would see roughly $333 a year back in running costs, putting the payback around 9 years. It's a genuine toss-up here, Homestead's numbers don't point clearly either way.

Homestead's weather, in the numbers that matter
Homestead barely has a winter to speak of, 51 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 4751 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 50.5°F, and the coldest daily reading in the 2024 station record was 50°F. That puts the seasonal coefficient of performance at 3.7 for the recommended standard unit. Homestead's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. Climate figures trace to the nearest NOAA station, Homestead AFB Airport, 4.1 miles from Homestead.
The yearly running costs in Homestead
On a typical 2000-square-foot house, heating needs here are close to nil, so the heat pump's electric bill, near $630 a year, is almost entirely air conditioning. Heating barely registers here, a gas furnace would burn about 1 Mcf a year at $25.48 per Mcf, so nearly all of the $964 a year the existing setup costs to run is the old air conditioner. At 15.43¢/kWh, the saving in Homestead comes from the heat pump being a more efficient air conditioner, not from heating. 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 $1,998 ahead.
The break-even point in Homestead
In Homestead the cooling savings outweigh the extra electricity for heating, so no plausible change in the electricity rate would make the old furnace and AC cheaper to run. A useful quote test for Homestead: the heat pump is worth it within a decade if it costs less than $3,330 more than replacing the furnace and AC, and within 7 years if the gap is under $2,331.
The other scenario: no gas furnace to begin with
Gas isn't universal in Homestead, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Where Homestead ranks in this dataset
