Punta Gorda's weather, in the numbers that matter
253 heating degree days pile up here every year, so Punta Gorda barely has a winter to speak of; the cooling side runs to 4274 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 41°F, and the coldest daily reading in the 2024 station record was 39.9°F. That puts the seasonal coefficient of performance at 3.42 for the recommended standard unit. Punta Gorda'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, Charlotte County Airport, 4.8 miles from Punta Gorda.
What it actually costs to run, year to year
On a typical 2000-square-foot house, heating needs here are close to nil, so the heat pump's electric bill, near $591 a year, is almost entirely air conditioning. Heating barely registers here, a gas furnace would burn about 3 Mcf a year at $25.48 per Mcf, so nearly all of the $922 a year the existing setup costs to run is the old air conditioner. At 15.43¢/kWh, the saving in Punta Gorda comes from the heat pump being a more efficient air conditioner, not from heating. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $1,959 ahead.
The break-even point in Punta Gorda
In Punta Gorda 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 Punta Gorda: the heat pump is worth it within a decade if it costs less than $3,310 more than replacing the furnace and AC, and within 7 years if the gap is under $2,317.
If your home heats with electric baseboard instead of gas
Plenty of homes in Punta Gorda heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Punta Gorda'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.
Punta Gorda against the rest of the country
