HeatPumpPayback

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 $3,500 more up front here (already netting out a $2,000 tax credit). 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 (record low -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 its running cost near $807 a year, against 17.03¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $4,124 behind.

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 $8,000 spent going electric in roughly 6.6 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.

What to do with this number in Columbus

About 51,970 people live in Columbus, 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.
