Heat pump vs. gas furnace in West Melbourne, FL
A heat pump earns back its extra cost in West Melbourne within a sensible timeframe. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. Lower bills claw that back: about $313 saved annually, for a payback of roughly 3.2 years. That's a real payback, built from West Melbourne's own climate and utility rates, not a national guess.
Why West Melbourne's climate drives this number
373 heating degree days pile up here every year, so West Melbourne barely has a winter to speak of; the cooling side runs to 3742 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 (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; West Melbourne's design temperature doesn't justify the cold-climate premium.

The month-to-month numbers for West Melbourne
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. The gas furnace it replaces burns roughly 4 Mcf a year at 25.48 per Mcf here, for a running cost near $847 a year (electricity here runs 15.43¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 35.2 years, leaving the 15-year total $3,691 ahead.
Electric resistance heat in West Melbourne, compared
Not every home in West Melbourne has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $359 a year, which recovers the extra $5,500 spent going electric in roughly 15.3 years.
Where West Melbourne ranks in this dataset
Ranked against the other 3206 cities covered, West Melbourne comes in at 3097 for heating severity — 1 would be the coldest place in the dataset — and 1306 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.
