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 low of 46.9°F in the 2024 station record. 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
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 Lake Worth Beach comes from the heat pump being a more efficient air conditioner, not from heating. 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.
The break-even point in Lake Worth Beach
In Lake Worth 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 Lake Worth 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.
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. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Lake Worth Beach against the rest of the country
