Heat Pump Payback in Paducah, KY
Paducah, KY: the heat pump payback math
Paducah technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Paducah would pay extra to go electric rather than replace the furnace and AC with the same again. Paducah's residents would see roughly $169 a year back in running costs, putting the payback around 32.6 years. That's a technicality, not a recommendation, for anyone actually living in Paducah.

Paducah's weather, in the numbers that matter
3070 heating degree days pile up here every year, so Paducah has a real but manageable winter; the cooling side runs to 1798 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 3.9°F, and the coldest daily reading in the 2024 station record was 1.9°F. That puts the seasonal coefficient of performance at 2.79 for the recommended cold-climate unit. Paducah needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from Barkley Regional Airport, the closest NOAA station, 7.2 miles out.
The yearly running costs in Paducah
Electricity use for heating alone comes out to about 2,786 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $622 a year. Paducah's gas rate of $14.23 per Mcf, applied to the 32 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $790 a year, against 14.39¢ per kWh for electricity. 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 $2,969 behind.
How sensitive Paducah's result is to prices
Gas would only overtake the heat pump in Paducah if electricity rose past 22.9¢/kWh from 14.39¢, or gas fell under $8.95 per Mcf from $14.23. A useful quote test for Paducah: the heat pump is worth it within a decade if it costs less than $1,690 more than replacing the furnace and AC, and within 7 years if the gap is under $1,183.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Paducah, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $832 a year comes back this way, enough that the 12-year payback clears the $10,000 premium comfortably within the equipment's life.
Paducah against the rest of the country
Among 3206 cities, Paducah's winter puts it at rank 1891 for severity, while its size puts it at rank 1492 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
