Temple Terrace, FL: the heat pump payback math
Temple Terrace clears a genuine payback here, inside a reasonable stretch of years. $1,000 is what Temple Terrace would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Temple Terrace's residents would see roughly $300 a year back in running costs, putting the payback around 3.3 years. The window here is reasonable, and it's specific to what Temple Terrace actually pays for power and gas.
How cold Temple Terrace actually gets
Temple Terrace barely has a winter to speak of — 512 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 3289 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 37.4°F, against a record low of 35.6°F. That puts the seasonal coefficient of performance at 3.31 for the recommended standard unit. Temple Terrace'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
Modelled on a typical 2000-square-foot house, the heat pump draws about 392 kWh a year to keep it warm, plus cooling, for a combined electric bill near $493 a year. The gas furnace it replaces burns roughly 5 Mcf a year at 25.48 per Mcf here, for a running cost near $794 a year (electricity here runs 15.43¢/kWh). Buy it outright, not incrementally, and payback stretches to 36.6 years; over 15 years the net position sits $3,507 ahead.
If your home heats with electric baseboard instead of gas
Not every home in Temple Terrace has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $365 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 15.1 years.
