Heat Pump Payback in Columbus, IN
Will a heat pump pay off in Columbus, IN?
In Columbus, a heat pump would cost more to run each year than what you have now. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Unfortunately the electric bill outweighs the gas bill it replaces by about $42 a year here, so the extra spend stays unrecovered. There's no spin on that: Columbus's numbers say wait.

Why Columbus's climate drives this number
Degree days tell the story here: Columbus racks up 4010 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1483 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 1.4°F here (coldest 2024 reading -5.8°F), which works out to a seasonal COP of 2.73 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, Columbus 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 3,719 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $849 a year. Columbus's gas rate of $11.49 per Mcf, applied to the 42 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $807 a year, against 17.03¢ per kWh for electricity. 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 $6,124 behind.
How sensitive Columbus's result is to prices
The heat pump would become the cheaper option in Columbus if electricity fell to 15.7¢/kWh (from 17.03¢) or gas rose above $12.49 per Mcf (from $11.49). At today's prices a cheaper quote cannot rescue the gas comparison in Columbus, since there is no yearly saving to recover it from.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Columbus, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Columbus's answer improves. The saving here runs about $1,208 a year, which recovers the extra $10,000 spent going electric in roughly 8.3 years.
Where Columbus ranks in this dataset
Columbus lands at position 1494 out of 3206 cities on heating severity (coldest is 1), and 783 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
