Is a heat pump worth it in Lynn Haven?
In Lynn Haven, a heat pump is the cheaper choice, and not by a little. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). Lynn Haven's residents would see roughly $363 a year back in running costs, putting the payback around 2.8 years. That verdict holds specifically for Lynn Haven's own climate and rates, not a national average.
How cold Lynn Haven actually gets
Lynn Haven barely has a winter to speak of — 958 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 3275 cooling degree days. 35.4°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 24.6°F on file. Worked through the model, that's a seasonal COP of 3.25 on the standard unit fit for this climate. Lynn Haven's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine.

The month-to-month numbers for Lynn Haven
Modelled on a typical 2000-square-foot house, the heat pump draws about 746 kWh a year to keep it warm, plus cooling, for a combined electric bill near $546 a year. Lynn Haven's gas rate of 25.48 per Mcf, applied to the 10 Mcf a year the furnace burns, puts its running cost near $909 a year, against 15.43¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 30.3 years; over 15 years the net position sits $4,446 ahead.
The other scenario: no gas furnace to begin with
Not every home in Lynn Haven has gas service. Swap the comparison to resistance heat instead of gas, and Lynn Haven's answer improves. Switching saves about $483 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $5,500 spent up front comes back in about 11.4 years.
Where Lynn Haven ranks in this dataset
