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 low of 33.1°F in the 2024 station record. 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 including the old AC (electricity here runs 15.43¢/kWh). Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $2,156 ahead.
The break-even point in Green Cove Springs
In Green Cove Springs 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 Green Cove Springs: the heat pump is worth it within a decade if it costs less than $3,440 more than replacing the furnace and AC, and within 7 years if the gap is under $2,408.
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. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
