Will a heat pump pay off in Punta Gorda, FL?

Punta Gorda clears a genuine payback here, inside a reasonable stretch of years. 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. Punta Gorda's residents would see roughly $331 a year back in running costs, putting the payback around 3 years. The window here is reasonable, and it's specific to what Punta Gorda actually pays for power and gas.

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, against a record low of 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

Electricity use for heating alone comes out to about 187 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $591 a year. The gas furnace it replaces burns roughly 3 Mcf a year at 25.48 per Mcf here, for a running cost near $922 a year (electricity here runs 15.43¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 33.3 years, leaving the 15-year total $3,959 ahead.

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. About $362 a year comes back this way, enough that the 15.2-year payback clears the $5,500 premium comfortably within the equipment's life.
