Gardner, KS: the heat pump payback math
In Gardner, 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 $3,500 after a $2,000 federal tax credit. Lower bills claw that back: about $138 saved annually, for a payback of roughly 25.3 years. Gardner's own numbers say this pencils out only in theory, not in practice.
Why Gardner's climate drives this number
3895 heating degree days pile up here every year, so Gardner 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. -4°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -8°F on file. Worked through the model, that's a seasonal COP of 2.6 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Gardner — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The month-to-month numbers for Gardner
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,793 kWh a year to keep it warm, plus cooling, for a combined electric bill near $779 a year. The gas furnace it replaces burns roughly 41 Mcf a year at 14.81 per Mcf here, for a running cost near $918 a year (electricity here runs 15.05¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 97.6 years, leaving the 15-year total $1,425 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Gardner — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Gardner's answer improves. The saving here runs about $1,022 a year, which recovers the extra $8,000 spent going electric in roughly 7.8 years.
How Gardner compares nationally
Among 3206 cities, Gardner's winter puts it at rank 1584 for severity, while its size puts it at rank 1552 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
What to do with this number in Gardner
About 25,836 people live in Gardner, Kansas, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

More on how this number was built
Every constant behind this page — the 2.6 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Gardner's -4°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
