Heat pump vs. gas furnace in Dyer, IN
Here in Dyer, the honest answer is that a heat pump raises your annual running cost. $3,500 is what Dyer would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Unfortunately the electric bill outweighs the gas bill it replaces by about $174 a year here, so the extra spend stays unrecovered. There's no spin on that: Dyer's numbers say wait.
The climate behind Dyer's payback figure
Degree days tell the story here: Dyer racks up 4971 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 864 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -5.3°F, against a record low of -10.7°F. That puts the seasonal coefficient of performance at 2.57 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Dyer sits firmly in cold-climate territory, so that's the class of unit priced here.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 4,898 heating kilowatt-hours annually on top of cooling, totalling about $960 a year on electricity. The gas furnace it replaces burns roughly 52 Mcf a year at 11.49 per Mcf here, for a running cost near $786 a year (electricity here runs 17.03¢/kWh). Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $6,110 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Dyer — 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. The saving here runs about $1,375 a year, which recovers the extra $8,000 spent going electric in roughly 5.8 years.
Where Dyer ranks in this dataset
Ranked against the other 3206 cities covered, Dyer comes in at 776 for heating severity — 1 would be the coldest place in the dataset — and 2263 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
