Should Davie switch to a heat pump?
Davie is a clear case: a heat pump beats what you have by a wide margin. 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). Lower bills claw that back: about $359 saved annually, for a payback of roughly 2.8 years. Nothing about that conclusion is generic — it's built entirely from Davie's own numbers.
The climate behind Davie's payback figure
54 heating degree days pile up here every year, so Davie barely has a winter to speak of; the cooling side runs to 5123 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 50°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 48.9°F on file. Worked through the model, that's a seasonal COP of 3.69 on the standard unit fit for this climate. A standard ducted system is enough here; Davie's design temperature doesn't justify the cold-climate premium. These numbers come from NORTH PERRY AIRPORT, the closest NOAA station, 6.1 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 37 kWh a year to keep it warm, plus cooling, for a combined electric bill near $680 a year. That compares with roughly 1 Mcf a year of gas at Davie's 25.48 per-Mcf rate — about $1,039 a year — against a local electricity rate of 15.43¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 30.6 years, leaving the 15-year total $4,386 ahead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Davie — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $366 a year, which recovers the extra $5,500 spent going electric in roughly 15 years.
Where Davie ranks in this dataset
Among 3206 cities, Davie's winter puts it at rank 3181 for severity, while its size puts it at rank 286 for population — 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
