Boca Raton, FL: the heat pump payback math
In Boca Raton, 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. Lower bills claw that back: about $374 saved annually, for a payback of roughly 2.7 years. That verdict holds specifically for Boca Raton's own climate and rates, not a national average.
Boca Raton's weather, in the numbers that matter
23 heating degree days pile up here every year, so Boca Raton barely has a winter to speak of; the cooling side runs to 5418 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 51.8°F, against a record low of 50°F. That puts the seasonal coefficient of performance at 3.74 for the recommended standard unit. Boca Raton's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. Climate figures trace to the nearest NOAA station, BOCA RATON AIRPORT, 0.5 miles from Boca Raton.
The month-to-month numbers for Boca Raton
Electricity use for heating alone comes out to about 16 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $715 a year. That compares with roughly 0 Mcf a year of gas at Boca Raton's 25.48 per-Mcf rate — about $1,090 a year — against a local electricity rate of 15.43¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 29.4 years, for a 15-year net position $4,615 ahead.
If your home heats with electric baseboard instead of gas
Not every home in Boca Raton 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 $377 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 14.6 years.
