Heat pump vs. gas furnace in Lake Worth Beach, FL
In Lake Worth Beach, a heat pump is the cheaper choice, and not by a little. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. Lake Worth Beach's residents would see roughly $334 a year back in running costs, putting the payback around 3 years. That verdict holds specifically for Lake Worth Beach's own climate and rates, not a national average.
Lake Worth Beach's weather, in the numbers that matter
Lake Worth 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. 48°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 46.9°F on file. Worked through the model, that's a seasonal COP of 3.63 on the standard unit fit for this climate. Lake Worth Beach's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine.

Lake Worth Beach's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 74 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $621 a year. The gas furnace it replaces burns roughly 1 Mcf a year at 25.48 per Mcf here, for a running cost near $955 a year (electricity here runs 15.43¢/kWh). Buy it outright, not incrementally, and payback stretches to 33 years; over 15 years the net position sits $4,005 ahead.
Electric resistance heat in Lake Worth Beach, compared
Not every home in Lake Worth Beach has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $347 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 15.9 years.
Lake Worth Beach against the rest of the country
Among 3206 cities, Lake Worth Beach's winter puts it at rank 3146 for severity, while its size puts it at rank 930 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.
