How cold Altamonte Springs actually gets
Altamonte Springs barely has a winter to speak of, 441 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 3735 cooling degree days. 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. Altamonte Springs's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine.

Altamonte Springs's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 324 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $541 a year. Altamonte Springs'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. 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 $1,839 ahead.
The break-even point in Altamonte Springs
In Altamonte Springs 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 Altamonte Springs: 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.
Electric resistance heat in Altamonte Springs, compared
Gas isn't universal in Altamonte Springs, 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.
How Altamonte Springs compares nationally
Ranked against the other 3206 cities covered, Altamonte Springs comes in at 3067 for heating severity, 1 would be the coldest place in the dataset, and 866 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.
