Should Altamonte Springs switch to a heat pump?
Altamonte Springs clears a genuine payback here, inside a reasonable stretch of years. $1,000 is what Altamonte Springs would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Altamonte Springs's residents would see roughly $323 a year back in running costs, putting the payback around 3.1 years. The window here is reasonable, and it's specific to what Altamonte Springs actually pays for power and gas.
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 (record low 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 its running cost near $864 a year, against 15.43¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 34.1 years, leaving the 15-year total $3,839 ahead.
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. Switching saves about $378 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $5,500 spent up front comes back in about 14.6 years.
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.
