Heat Pump Payback in Casselberry, FL
Is a heat pump worth it in Casselberry?
In Casselberry, the math is close enough that it comes down to how long you plan to stay. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. Lower bills claw that back: about $323 saved annually, for a payback of roughly 9.3 years. Whether that's worth it in Casselberry depends on how many years you expect to own the place.

The climate behind Casselberry's payback figure
Degree days tell the story here: Casselberry racks up 441 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3735 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 42.1°F here (coldest 2024 reading 37°F), which works out to a seasonal COP of 3.45 for the standard class of unit this climate calls for. A standard ducted system is enough here; Casselberry's design temperature doesn't justify the cold-climate premium. These numbers come from Executive Airport, the closest NOAA station, 8.1 miles out.
The yearly running costs in Casselberry
A 2000-square-foot house here would pull roughly 324 heating kilowatt-hours annually on top of cooling, totalling about $541 a year on electricity. Casselberry'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 $864 a year, against 15.43¢ per kWh for electricity. 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 $1,839 ahead.
What would change Casselberry's answer
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 Casselberry at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $323 a year saved, a difference under $2,261 pays back within 7 years here, and under $3,230 within 10.
Electric resistance heat in Casselberry, compared
Gas isn't universal in Casselberry, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. 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 Casselberry ranks in this dataset
