Why Palm Beach Gardens's climate drives this number
106 heating degree days pile up here every year, so Palm Beach Gardens barely has a winter to speak of; the cooling side runs to 4633 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. Sizing runs off the design temperature, not the average day: 48°F here (coldest 2024 reading 46.9°F), which works out to a seasonal COP of 3.63 for the standard class of unit this climate calls for. A standard ducted system is enough here; Palm Beach Gardens's design temperature doesn't justify the cold-climate premium.

What it actually costs to run, year to year
Heating hardly figures in Palm Beach Gardens: on a 2000-square-foot reference house the heat pump's roughly $621 yearly electric bill is nearly all cooling. With so little heating demand, a furnace in Palm Beach Gardens would burn only about 1 Mcf a year ($25.48 per Mcf); almost all of the $955 yearly running cost of the current system is cooling, at 15.43¢/kWh. Any saving here is really a cooling-efficiency saving. 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 $2,005 ahead.
What would change Palm Beach Gardens's answer
Because the heat pump's better air conditioning saves more electricity than its heating uses, it stays cheaper to run than the current furnace and AC in Palm Beach Gardens at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $334 a year saved, a difference under $2,338 pays back within 7 years here, and under $3,340 within 10.
Electric resistance heat in Palm Beach Gardens, compared
Gas isn't universal in Palm Beach Gardens, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Palm Beach Gardens's answer improves. Even against resistance heat, the running-cost gap here isn't enough to clear the $7,500 incremental cost within the equipment's 15-year life.
