Heat Pump Payback in Doral, FL
Heat pump vs. gas furnace in Doral, FL
Doral sits right on the fence, how long you'll own the house decides this one. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. Lower bills claw that back: about $339 saved annually, for a payback of roughly 8.9 years. It's a genuine toss-up here, Doral's numbers don't point clearly either way.

How cold Doral actually gets
Doral barely has a winter to speak of, 41 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 4858 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 52°F, and the coldest daily reading in the 2024 station record was 52°F. That puts the seasonal coefficient of performance at 3.75 for the recommended standard unit. Doral's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine.

What it actually costs to run, year to year
On a typical 2000-square-foot house, heating needs here are close to nil, so the heat pump's electric bill, near $643 a year, is almost entirely air conditioning. Heating barely registers here, a gas furnace would burn about 0 Mcf a year at $25.48 per Mcf, so nearly all of the $982 a year the existing setup costs to run is the old air conditioner. At 15.43¢/kWh, the saving in Doral 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 $2,084 ahead.
What would change Doral's answer
In Doral 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 Doral: the heat pump is worth it within a decade if it costs less than $3,390 more than replacing the furnace and AC, and within 7 years if the gap is under $2,373.
If your home heats with electric baseboard instead of gas
Not every home in Doral has gas service. Swap the comparison to resistance heat instead of gas, and Doral'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.
Where Doral ranks in this dataset
Ranked against the other 3206 cities covered, Doral comes in at 3192 for heating severity, 1 would be the coldest place in the dataset, and 438 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
