Should Columbus switch to a heat pump?
The payback math works in Columbus on paper, past the equipment's own working life. 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. Lower bills claw that back: about $30 saved annually, for a payback of roughly 115.3 years. Columbus's own numbers say this pencils out only in theory, not in practice.
Why Columbus's climate drives this number
4266 heating degree days pile up here every year, so Columbus has a real but manageable winter; the cooling side runs to 1378 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 6.1°F, against a record low of 6.1°F. That puts the seasonal coefficient of performance at 2.85 for the recommended cold-climate unit. Columbus needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

The month-to-month numbers for Columbus
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,790 kWh a year to keep it warm, plus cooling, for a combined electric bill near $914 a year. Columbus's gas rate of 13.85 per Mcf, applied to the 44 Mcf a year the furnace burns, puts its running cost near $944 a year, against 18.40¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 444.7 years; over 15 years the net position sits $3,045 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Columbus — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,403 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 5.7 years.
Where Columbus ranks in this dataset
Among 3206 cities, Columbus's winter puts it at rank 1360 for severity, while its size puts it at rank 15 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

More on how this number was built
Every constant behind this page — the 2.85 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a 6.1°F design temperature, Columbus sits in cold-climate territory; the guide to that class of unit explains why.
