Heat Pump Payback in Mount Dora, FL
Mount Dora, FL: the heat pump payback math
In Mount Dora, 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 $326 saved annually, for a payback of roughly 9.2 years. It's a genuine toss-up here, Mount Dora's numbers don't point clearly either way.

Mount Dora's weather, in the numbers that matter
605 heating degree days pile up here every year, so Mount Dora barely has a winter to speak of; the cooling side runs to 3480 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: 36°F here (coldest 2024 reading 34°F), which works out to a seasonal COP of 3.27 for the standard class of unit this climate calls for. Mount Dora's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. These numbers come from Leesburg Regional Airport, the closest NOAA station, 10.7 miles out.
Mount Dora's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 468 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $530 a year. The gas furnace it replaces burns roughly 6 Mcf a year at $25.48 per Mcf here, for a running cost near $856 a year including the old AC (electricity here runs 15.43¢/kWh). 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 $1,895 ahead.
What would change Mount Dora's answer
In Mount Dora 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 Mount Dora: the heat pump is worth it within a decade if it costs less than $3,260 more than replacing the furnace and AC, and within 7 years if the gap is under $2,282.
Electric resistance heat in Mount Dora, compared
Plenty of homes in Mount Dora 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. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Where Mount Dora ranks in this dataset
Ranked against the other 3206 cities covered, Mount Dora comes in at 3033 for heating severity, 1 would be the coldest place in the dataset, and 2067 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.
