Heat Pump Payback in Spring Hill, KS
Spring Hill, KS: the heat pump payback math
In Spring Hill, 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. Lower bills claw that back: about $138 saved annually, for a payback of roughly 39.8 years. Spring Hill's own numbers say this pencils out only in theory, not in practice.

Why Spring Hill's climate drives this number
3895 heating degree days pile up here every year, so Spring Hill has a real but manageable winter; the cooling side runs to 1625 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: -4°F here (coldest 2024 reading -8°F), which works out to a seasonal COP of 2.6 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, Spring Hill sits firmly in cold-climate territory, so that's the class of unit priced here.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 3,793 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $779 a year. Spring Hill's gas rate of $14.81 per Mcf, applied to the 41 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $918 a year, against 15.05¢ 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 $3,425 behind.
What would change Spring Hill's answer
This result holds unless electricity climbs above 19.6¢/kWh (it is 15.05¢ now) or gas drops below $11.40 per Mcf (now $14.81); past either point, gas becomes the cheaper fuel in Spring Hill. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $138 a year saved, a difference under $966 pays back within 7 years here, and under $1,380 within 10.
Electric resistance heat in Spring Hill, compared
Not every home in Spring Hill has gas service. Swap the comparison to resistance heat instead of gas, and Spring Hill's answer improves. About $1,022 a year comes back this way, enough that the 9.8-year payback clears the $10,000 premium comfortably within the equipment's life.
Spring Hill against the rest of the country
Spring Hill lands at position 1589 out of 3206 cities on heating severity (coldest is 1), and 3188 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
