Margate, FL: the heat pump payback math
In Margate, a heat pump is the cheaper choice, and not by a little. 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). Margate's residents would see roughly $352 a year back in running costs, putting the payback around 2.8 years. Nothing about that conclusion is generic — it's built entirely from Margate's own numbers.
Why Margate's climate drives this number
Degree days tell the story here: Margate racks up 65 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 4997 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 50°F here (record low 48.9°F), which works out to a seasonal COP of 3.69 for the standard class of unit this climate calls for. A standard ducted system is enough here; Margate's design temperature doesn't justify the cold-climate premium.

The month-to-month numbers for Margate
A 2000-square-foot house here would pull roughly 45 heating kilowatt-hours annually on top of cooling, totalling about $664 a year on electricity. The gas furnace it replaces burns roughly 1 Mcf a year at 25.48 per Mcf here, for a running cost near $1,017 a year (electricity here runs 15.43¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 31.2 years, leaving the 15-year total $4,283 ahead.
Electric resistance heat in Margate, compared
Gas isn't universal in Margate — 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 saving here runs about $360 a year, which recovers the extra $5,500 spent going electric in roughly 15.3 years.
Where Margate ranks in this dataset
Margate lands at position 3160 out of 3206 cities on heating severity (coldest is 1), and 660 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
