Heat Pump Payback in Hays, KS
Hays, KS: the heat pump payback math
Hays technically pencils out, but only past the point the equipment would need replacing anyway. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Hays's residents would see roughly $125 a year back in running costs, putting the payback around 44.1 years. Hays's own numbers say this pencils out only in theory, not in practice.

The climate behind Hays's payback figure
Degree days tell the story here: Hays racks up 4726 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1406 cooling degree days on the cooling side. -5.1°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -16.1°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.58 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Hays, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The yearly running costs in Hays
Electricity use for heating alone comes out to about 4,638 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $878 a year. Hays's gas rate of $14.81 per Mcf, applied to the 49 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $1,003 a year, against 15.05¢ 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 $3,630 behind.
How sensitive Hays's result is to prices
This result holds unless electricity climbs above 18.2¢/kWh (it is 15.05¢ now) or gas drops below $12.28 per Mcf (now $14.81); past either point, gas becomes the cheaper fuel in Hays. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $125 a year saved, a difference under $875 pays back within 7 years here, and under $1,250 within 10.
The other scenario: no gas furnace to begin with
Not every home in Hays has gas service. Swap the comparison to resistance heat instead of gas, and Hays's answer improves. About $1,197 a year comes back this way, enough that the 8.4-year payback clears the $10,000 premium comfortably within the equipment's life.
Hays against the rest of the country
Among 3206 cities, Hays's winter puts it at rank 1003 for severity, while its size puts it at rank 1830 for population, 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where Hays's figure comes from
