Wabash, IN: the heat pump payback math
Wabash is a place where a heat pump genuinely costs more to operate than the alternative. 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. The heat pump would cost about $163 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Wabash's numbers say wait.
Why Wabash's climate drives this number
4675 heating degree days pile up here every year, so Wabash has a real but manageable winter; the cooling side runs to 1026 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -7.6°F, against a record low of -7.8°F. That puts the seasonal coefficient of performance at 2.52 for the recommended cold-climate unit. A cold-climate unit is the right call in Wabash — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from GRISSOM AFB AIRPORT, the closest NOAA station, 19.8 miles out.
The month-to-month numbers for Wabash
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,698 kWh a year to keep it warm, plus cooling, for a combined electric bill near $949 a year. Wabash's gas rate of 11.49 per Mcf, applied to the 49 Mcf a year the furnace burns, puts its running cost near $786 a year, against 17.03¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $5,946 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Wabash — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $1,293 a year comes back this way, enough that the 6.2-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Wabash ranks in this dataset
Ranked against the other 3206 cities covered, Wabash comes in at 1019 for heating severity — 1 would be the coldest place in the dataset — and 3130 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

About 10,275 people live in Wabash, Indiana, 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.
Ask a local HVAC contractor for a quote before committing either way.

The methodology guide walks through exactly how Wabash's 2.52 seasonal COP and the rest of this page's numbers get built. Wabash's -7.6°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.
