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 $3,500 after a $2,000 federal tax credit. That premium is recovered through $158 of lower running costs every year, landing the payback clock at roughly 22.1 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 (record low -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 month-to-month numbers for 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 — against a local electricity rate of 14.39¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 85.2 years, for a 15-year net position $1,124 behind.
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 8.6-year payback clears the $8,000 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.
