Heat Pump Payback in Bardstown, KY
Is a heat pump worth it in Bardstown?
Bardstown technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Bardstown would pay extra to go electric rather than replace the furnace and AC with the same again. That premium is recovered through $165 of lower running costs every year, landing the payback clock at roughly 33.4 years. That's a technicality, not a recommendation, for anyone actually living in Bardstown.

Bardstown's weather, in the numbers that matter
Degree days tell the story here: Bardstown racks up 3507 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1389 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 7.3°F, and the coldest daily reading in the 2024 station record was -3.8°F. That puts the seasonal coefficient of performance at 2.88 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Bardstown sits firmly in cold-climate territory, so that's the class of unit priced here.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 3,083 heating kilowatt-hours annually on top of cooling, totalling about $614 a year on electricity. That compares with roughly 37 Mcf a year of gas at Bardstown's $14.23 per-Mcf rate, about $779 a year with the old AC included, against a local electricity rate of 14.39¢/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 $3,030 behind.
How sensitive Bardstown's result is to prices
Gas would only overtake the heat pump in Bardstown if electricity rose past 21.1¢/kWh from 14.39¢, or gas fell under $9.72 per Mcf from $14.23. A useful quote test for Bardstown: the heat pump is worth it within a decade if it costs less than $1,650 more than replacing the furnace and AC, and within 7 years if the gap is under $1,155.
Electric resistance heat in Bardstown, compared
