Heat Pump Payback in Radcliff, KY
Should Radcliff switch to a heat pump?
In Radcliff, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Radcliff's residents would see roughly $155 a year back in running costs, putting the payback around 35.5 years. Radcliff's own numbers say this pencils out only in theory, not in practice.

Why Radcliff's climate drives this number
Degree days tell the story here: Radcliff racks up 3554 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1370 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 5°F here (coldest 2024 reading 0.1°F), which works out to a seasonal COP of 2.82 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Radcliff, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 3,191 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $627 a year. Radcliff's gas rate of $14.23 per Mcf, applied to the 37 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $782 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 $3,177 behind.
The break-even point in Radcliff
This result holds unless electricity climbs above 20.4¢/kWh (it is 14.39¢ now) or gas drops below $10.05 per Mcf (now $14.23); past either point, gas becomes the cheaper fuel in Radcliff. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $155 a year saved, a difference under $1,085 pays back within 7 years here, and under $1,550 within 10.
If your home heats with electric baseboard instead of gas
Plenty of homes in Radcliff heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Radcliff's answer improves. The saving here runs about $923 a year, which recovers the extra $10,000 spent going electric in roughly 10.8 years.
Where Radcliff ranks in this dataset
