Heat Pump Payback in Royal Palm Beach, FL
Royal Palm Beach, FL: the heat pump payback math
Royal Palm Beach 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. That premium is recovered through $334 of lower running costs every year, landing the payback clock at roughly 9 years. It's a genuine toss-up here, Royal Palm Beach's numbers don't point clearly either way.

Royal Palm Beach's weather, in the numbers that matter
Royal Palm Beach barely has a winter to speak of, 106 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 4633 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 48°F, and the coldest daily reading in the 2024 station record was 46.9°F. That puts the seasonal coefficient of performance at 3.63 for the recommended standard unit. Royal Palm Beach'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 $621 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 $955 a year the existing setup costs to run is the old air conditioner. At 15.43¢/kWh, the saving in Royal Palm Beach 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 $2,005 ahead.
The break-even point in Royal Palm Beach
In Royal Palm Beach 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 Royal Palm Beach: the heat pump is worth it within a decade if it costs less than $3,340 more than replacing the furnace and AC, and within 7 years if the gap is under $2,338.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Royal Palm Beach, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Royal Palm Beach'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 Royal Palm Beach ranks in this dataset
