Should Palm Bay switch to a heat pump?

Palm Bay clears a genuine payback here, inside a reasonable stretch of years. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). Palm Bay's residents would see roughly $313 a year back in running costs, putting the payback around 3.2 years. That's a real payback, built from Palm Bay's own climate and utility rates, not a national guess.

Why Palm Bay's climate drives this number

Palm Bay barely has a winter to speak of — 373 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 3742 cooling degree days. Sizing runs off the design temperature, not the average day: 42.1°F here (record low 39.9°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; Palm Bay's design temperature doesn't justify the cold-climate premium.

The month-to-month numbers for Palm Bay

Modelled on a typical 2000-square-foot house, the heat pump draws about 274 kWh a year to keep it warm, plus cooling, for a combined electric bill near $535 a year. Palm Bay's gas rate of 25.48 per Mcf, applied to the 4 Mcf a year the furnace burns, puts its running cost near $847 a year, against 15.43¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 35.2 years, for a 15-year net position $3,691 ahead.

The other scenario: no gas furnace to begin with

Not every home in Palm Bay has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $359 a year comes back this way, enough that the 15.3-year payback clears the $5,500 premium comfortably within the equipment's life.

Palm Bay against the rest of the country

Ranked against the other 3206 cities covered, Palm Bay comes in at 3095 for heating severity — 1 would be the coldest place in the dataset — and 197 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.
