Bowling Green, KY: the heat pump payback math
The payback math works in Bowling Green on paper, past the equipment's own working life. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Bowling Green's residents would see roughly $193 a year back in running costs, putting the payback around 18.1 years. That's a technicality, not a recommendation, for anyone actually living in Bowling Green.
How cold Bowling Green actually gets
Degree days tell the story here: Bowling Green racks up 3009 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1883 cooling degree days on the cooling side. 10°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 1°F on file. Worked through the model, that's a seasonal COP of 2.94 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Bowling Green sits firmly in cold-climate territory, so that's the class of unit priced here.

The month-to-month numbers for Bowling Green
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,592 kWh a year to keep it warm, plus cooling, for a combined electric bill near $604 a year. That compares with roughly 31 Mcf a year of gas at Bowling Green's 14.23 per-Mcf rate — about $797 a year — against a local electricity rate of 14.39¢/kWh. Buy it outright, not incrementally, and payback stretches to 69.9 years; over 15 years the net position sits $603 behind.
The other scenario: no gas furnace to begin with
Not every home in Bowling Green has gas service. Swap the comparison to resistance heat instead of gas, and Bowling Green's answer improves. The saving here runs about $844 a year, which recovers the extra $8,000 spent going electric in roughly 9.5 years.
How Bowling Green compares nationally
Bowling Green lands at position 1921 out of 3206 cities on heating severity (coldest is 1), and 472 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
