Heat Pump Payback in Madisonville, KY
Should Madisonville switch to a heat pump?
In Madisonville, the extra upfront cost technically comes back, just not before the equipment wears out. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Madisonville's residents would see roughly $156 a year back in running costs, putting the payback around 35.3 years. Madisonville's own numbers say this pencils out only in theory, not in practice.

The climate behind Madisonville's payback figure
Madisonville has a real but manageable winter, 3325 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1478 cooling degree days. 4.6°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 0.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.81 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Madisonville 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 2,996 heating kilowatt-hours annually on top of cooling, totalling about $612 a year on electricity. Madisonville's gas rate of $14.23 per Mcf, applied to the 35 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $768 a year, against 14.39¢ per kWh for electricity. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $3,161 behind.
How sensitive Madisonville's result is to prices
This result holds unless electricity climbs above 21.1¢/kWh (it is 14.39¢ now) or gas drops below $9.73 per Mcf (now $14.23); past either point, gas becomes the cheaper fuel in Madisonville. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $156 a year saved, a difference under $1,092 pays back within 7 years here, and under $1,560 within 10.
The other scenario: no gas furnace to begin with
Plenty of homes in Madisonville 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 $875 a year comes back this way, enough that the 11.4-year payback clears the $10,000 premium comfortably within the equipment's life.
