Heat Pump Payback in Winter Park, FL
Should Winter Park switch to a heat pump?
In Winter Park, 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. It's a genuine toss-up here, Winter Park's numbers don't point clearly either way.

How cold Winter Park actually gets
441 heating degree days pile up here every year, so Winter Park barely has a winter to speak of; the cooling side runs to 3735 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 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. Winter Park'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
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. Winter Park'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. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $1,839 ahead.
How sensitive Winter Park's result is to prices
In Winter Park 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 Winter Park: the heat pump is worth it within a decade if it costs less than $3,230 more than replacing the furnace and AC, and within 7 years if the gap is under $2,261.
The other scenario: no gas furnace to begin with
Gas isn't universal in Winter Park, many houses run on electric heat already. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Where Winter Park ranks in this dataset
Among 3206 cities, Winter Park's winter puts it at rank 3069 for severity, while its size puts it at rank 1322 for population, 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
