Heat Pump Payback in Weston, FL
Weston, FL: the heat pump payback math
In Weston, the math is close enough that it comes down to how long you plan to stay. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,000. Weston's residents would see roughly $359 a year back in running costs, putting the payback around 8.4 years. It's a genuine toss-up here, Weston's numbers don't point clearly either way.

How cold Weston actually gets
Degree days tell the story here: Weston racks up 54 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 5123 cooling degree days on the cooling side. 50°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 48.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.69 on the standard unit fit for this climate. Weston's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. Climate figures trace to the nearest NOAA station, North Perry Airport, 12.2 miles from Weston.
The yearly running costs in Weston
On a typical 2000-square-foot house, heating needs here are close to nil, so the heat pump's electric bill, near $680 a year, is almost entirely air conditioning. Heating barely registers here, a gas furnace would burn about 1 Mcf a year at $25.48 per Mcf, so nearly all of the $1,039 a year the existing setup costs to run is the old air conditioner. At 15.43¢/kWh, the saving in Weston comes from the heat pump being a more efficient air conditioner, not from heating. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $2,386 ahead.
The break-even point in Weston
In Weston the cooling savings outweigh the extra electricity for heating, so no plausible change in the electricity rate would make the old furnace and AC cheaper to run. A useful quote test for Weston: the heat pump is worth it within a decade if it costs less than $3,590 more than replacing the furnace and AC, and within 7 years if the gap is under $2,513.
The other scenario: no gas furnace to begin with
Plenty of homes in Weston heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Weston's answer improves. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Weston against the rest of the country
Weston lands at position 3182 out of 3206 cities on heating severity (coldest is 1), and 550 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.
What to do with this number in Weston

Nothing above is a black box: the methodology guide shows the full arithmetic behind Weston's 3.69 seasonal COP and payback figure. Homes in Weston without gas service should read the electric-resistance comparison instead, the numbers there differ from the gas case above.
