Heat pump vs. gas furnace in Channahon, IL
In Channahon, 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). The heat pump would cost about $235 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Channahon's numbers say wait.
Why Channahon's climate drives this number
4733 heating degree days pile up here every year, so Channahon has a real but manageable winter; the cooling side runs to 1089 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 -4.4°F, against a record low of -10.3°F. That puts the seasonal coefficient of performance at 2.59 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Channahon 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 4,627 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,059 a year. Channahon's gas rate of 11.25 per Mcf, applied to the 49 Mcf a year the furnace burns, puts its running cost near $824 a year, against 19.06¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $7,031 behind.
The other scenario: no gas furnace to begin with
Not every home in Channahon has gas service. Swap the comparison to resistance heat instead of gas, and Channahon's answer improves. Switching saves about $1,494 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 5.4 years.
Where Channahon ranks in this dataset
Channahon lands at position 999 out of 3206 cities on heating severity (coldest is 1), and 2463 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where Channahon's figure comes from
Every constant behind this page — the 2.59 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Channahon's -4.4°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.
