Should Cooper City switch to a heat pump?
The math in Cooper City isn't close — a heat pump wins outright. $1,000 is what Cooper City would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. That premium is recovered through $359 of lower running costs every year, landing the payback clock at roughly 2.8 years. That verdict holds specifically for Cooper City's own climate and rates, not a national average.
Cooper City's weather, in the numbers that matter
54 heating degree days pile up here every year, so Cooper City barely has a winter to speak of; the cooling side runs to 5123 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 50°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 48.9°F on file. Worked through the model, that's a seasonal COP of 3.69 on the standard unit fit for this climate. Cooper City's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. These numbers come from NORTH PERRY AIRPORT, the closest NOAA station, 4.4 miles out.
The month-to-month numbers for Cooper City
Modelled on a typical 2000-square-foot house, the heat pump draws about 37 kWh a year to keep it warm, plus cooling, for a combined electric bill near $680 a year. Cooper City's gas rate of 25.48 per Mcf, applied to the 1 Mcf a year the furnace burns, puts its running cost near $1,039 a year, against 15.43¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 30.6 years, leaving the 15-year total $4,386 ahead.
The other scenario: no gas furnace to begin with
Not every home in Cooper City has gas service. Swap the comparison to resistance heat instead of gas, and Cooper City's answer improves. Switching saves about $366 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $5,500 spent up front comes back in about 15 years.
Where Cooper City ranks in this dataset
Among 3206 cities, Cooper City's winter puts it at rank 3186 for severity, while its size puts it at rank 1156 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.
