Heat Pump Payback in Campbellsville, KY
Will a heat pump pay off in Campbellsville, KY?
Campbellsville technically pencils out, but only past the point the equipment would need replacing anyway. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. That premium is recovered through $158 of lower running costs every year, landing the payback clock at roughly 34.7 years. Campbellsville's own numbers say this pencils out only in theory, not in practice.

Why Campbellsville's climate drives this number
Degree days tell the story here: Campbellsville racks up 3550 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1204 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 8.6°F here (coldest 2024 reading -4°F), which works out to a seasonal COP of 2.91 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Campbellsville sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from Campbellville / Taylor Co, the closest NOAA station, 2.6 miles out.
The yearly running costs in Campbellsville
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,089 kWh a year to keep it warm, plus cooling, for a combined electric bill near $592 a year. That compares with roughly 37 Mcf a year of gas at Campbellsville's $14.23 per-Mcf rate, about $751 a year with the old AC included, against a local electricity rate of 14.39¢/kWh. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $3,124 behind.
What would change Campbellsville's answer
This result holds unless electricity climbs above 20.6¢/kWh (it is 14.39¢ now) or gas drops below $9.95 per Mcf (now $14.23); past either point, gas becomes the cheaper fuel in Campbellsville. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $158 a year saved, a difference under $1,106 pays back within 7 years here, and under $1,580 within 10.
If your home heats with electric baseboard instead of gas
Plenty of homes in Campbellsville heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. About $926 a year comes back this way, enough that the 10.8-year payback clears the $10,000 premium comfortably within the equipment's life.
How Campbellsville compares nationally
Ranked against the other 3206 cities covered, Campbellsville comes in at 1757 for heating severity, 1 would be the coldest place in the dataset, and 2838 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
