Heat Pump Payback in Temple Terrace, FL
Temple Terrace, FL: the heat pump payback math
Temple Terrace sits right on the fence, how long you'll own the house decides this one. $3,000 is what Temple Terrace would pay extra to go electric rather than replace the furnace and AC with the same again. Temple Terrace's residents would see roughly $300 a year back in running costs, putting the payback around 10 years. It's a genuine toss-up here, Temple Terrace's numbers don't point clearly either way.

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, and the coldest daily reading in the 2024 station record was 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 including the old AC (electricity here runs 15.43¢/kWh). 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 $1,507 ahead.
The break-even point in Temple Terrace
In Temple Terrace 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 Temple Terrace: the heat pump is worth it within a decade if it costs less than $3,000 more than replacing the furnace and AC, and within 7 years if the gap is under $2,100.
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. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
