Miami Shores's weather, in the numbers that matter
Degree days tell the story here: Miami Shores racks up 60 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 4759 cooling degree days on the cooling side. 51.1°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 48.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.72 on the standard unit fit for this climate. Miami Shores's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine.

Miami Shores'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 $632 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 $968 a year the existing setup costs to run is the old air conditioner. At 15.43¢/kWh, the saving in Miami Shores comes from the heat pump being a more efficient air conditioner, not from heating. 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.
How sensitive Miami Shores's result is to prices
In Miami Shores 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 Miami Shores: the heat pump is worth it within a decade if it costs less than $3,350 more than replacing the furnace and AC, and within 7 years if the gap is under $2,345.
Electric resistance heat in Miami Shores, compared
Gas isn't universal in Miami Shores, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Miami Shores's answer improves. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
