How cold Cutler Bay actually gets
Cutler Bay 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. Sizing runs off the design temperature, not the average day: 50.5°F here (coldest 2024 reading 50°F), which works out to a seasonal COP of 3.7 for the standard class of unit this climate calls for. Cutler Bay's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine.

Cutler Bay's running-cost comparison, in dollars
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 Cutler Bay comes from the heat pump being a more efficient air conditioner, not from heating. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,998 ahead.
How sensitive Cutler Bay's result is to prices
In Cutler Bay 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 Cutler Bay: 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.
If your home heats with electric baseboard instead of gas
Not every home in Cutler Bay has gas service. 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.
Cutler Bay against the rest of the country
Cutler Bay lands at position 3190 out of 3206 cities on heating severity (coldest is 1), and 894 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
