Heat Pump Payback in Longwood, FL
Will a heat pump pay off in Longwood, FL?
In Longwood, the math is close enough that it comes down to how long you plan to stay. $3,000 is what Longwood would pay extra to go electric rather than replace the furnace and AC with the same again. Longwood's residents would see roughly $313 a year back in running costs, putting the payback around 9.6 years. Whether that's worth it in Longwood depends on how many years you expect to own the place.

The climate behind Longwood's payback figure
Degree days tell the story here: Longwood racks up 497 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3473 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 41°F, and the coldest daily reading in the 2024 station record was 37.9°F. That puts the seasonal coefficient of performance at 3.42 for the recommended standard unit. A standard ducted system is enough here; Longwood's design temperature doesn't justify the cold-climate premium. These numbers come from Orlando Sanford Airport, the closest NOAA station, 8.3 miles out.
Longwood's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 368 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $514 a year. Longwood's gas rate of $25.48 per Mcf, applied to the 5 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $826 a year, against 15.43¢ per kWh for electricity. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $1,691 ahead.
The break-even point in Longwood
Because the heat pump's better air conditioning saves more electricity than its heating uses, it stays cheaper to run than the current furnace and AC in Longwood at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $313 a year saved, a difference under $2,191 pays back within 7 years here, and under $3,130 within 10.
Electric resistance heat in Longwood, compared
Plenty of homes in Longwood heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. Even against resistance heat, the running-cost gap here isn't enough to clear the $7,500 incremental cost within the equipment's 15-year life.
Where Longwood ranks in this dataset
Ranked against the other 3206 cities covered, Longwood comes in at 3059 for heating severity, 1 would be the coldest place in the dataset, and 2185 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
