Will a heat pump pay off in Green Cove Springs, FL?

Green Cove Springs is a clear case: a heat pump beats what you have by a wide margin. $1,000 is what Green Cove Springs would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Green Cove Springs's residents would see roughly $344 a year back in running costs, putting the payback around 2.9 years. That verdict holds specifically for Green Cove Springs's own climate and rates, not a national average.

How cold Green Cove Springs actually gets

Green Cove Springs barely has a winter to speak of — 709 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 3536 cooling degree days. 34°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 33.1°F on file. Worked through the model, that's a seasonal COP of 3.21 on the standard unit fit for this climate. Green Cove Springs's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. These numbers come from JACKSONVILLE NAS, the closest NOAA station, 17.1 miles out.

Green Cove Springs's running-cost comparison, in dollars

Modelled on a typical 2000-square-foot house, the heat pump draws about 559 kWh a year to keep it warm, plus cooling, for a combined electric bill near $551 a year. The gas furnace it replaces burns roughly 7 Mcf a year at 25.48 per Mcf here, for a running cost near $895 a year (electricity here runs 15.43¢/kWh). Buy it outright, not incrementally, and payback stretches to 32 years; over 15 years the net position sits $4,156 ahead.

If your home heats with electric baseboard instead of gas

Not every home in Green Cove Springs has gas service. Swap the comparison to resistance heat instead of gas, and Green Cove Springs's answer improves. About $433 a year comes back this way, enough that the 12.7-year payback clears the $5,500 premium comfortably within the equipment's life.

Green Cove Springs against the rest of the country
