Heat Pump Payback in Bluffton, IN
Should Bluffton switch to a heat pump?
Bluffton is a place where a heat pump genuinely costs more to operate than the alternative. $5,500 is what Bluffton would pay extra to go electric rather than replace the furnace and AC with the same again. Running costs here land $128 a year higher than the furnace it replaces, so that premium is never recovered. There's no spin on that: Bluffton's numbers say wait.

Why Bluffton's climate drives this number
Bluffton has a real but manageable winter, 4861 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 963 cooling degree days. Sizing runs off the design temperature, not the average day: -0.9°F here (coldest 2024 reading -6°F), which works out to a seasonal COP of 2.68 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, Bluffton sits firmly in cold-climate territory, so that's the class of unit priced here.

The yearly running costs in Bluffton
A 2000-square-foot house here would pull roughly 4,593 heating kilowatt-hours annually on top of cooling, totalling about $922 a year on electricity. The gas furnace it replaces burns roughly 51 Mcf a year at $11.49 per Mcf here, for a running cost near $794 a year including the old AC (electricity here runs 17.03¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $7,416 behind.
What would change Bluffton's answer
The heat pump would become the cheaper option in Bluffton if electricity fell to 14.0¢/kWh (from 17.03¢) or gas rose above $14.01 per Mcf (from $11.49). At today's prices a cheaper quote cannot rescue the gas comparison in Bluffton, since there is no yearly saving to recover it from.
The other scenario: no gas furnace to begin with
Plenty of homes in Bluffton heat with electricity alone, no gas line involved. 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 $1,387 a year, which recovers the extra $10,000 spent going electric in roughly 7.2 years.
How Bluffton compares nationally
Ranked against the other 3206 cities covered, Bluffton comes in at 895 for heating severity, 1 would be the coldest place in the dataset, and 3075 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where Bluffton's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Bluffton's 2.68 seasonal COP and payback figure. Bluffton's -0.9°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.
