Should Champaign switch to a heat pump?
Champaign is a place where a heat pump genuinely costs more to operate than the alternative. 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. Unfortunately the electric bill outweighs the gas bill it replaces by about $192 a year here, so the extra spend stays unrecovered. There's no spin on that: Champaign's numbers say wait.
The climate behind Champaign's payback figure
4571 heating degree days pile up here every year, so Champaign has a real but manageable winter; the cooling side runs to 1128 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: -0.9°F here (record low -9.4°F), which works out to a seasonal COP of 2.68 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Champaign — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 4,319 heating kilowatt-hours annually on top of cooling, totalling about $1,006 a year on electricity. The gas furnace it replaces burns roughly 48 Mcf a year at 11.25 per Mcf here, for a running cost near $814 a year (electricity here runs 19.06¢/kWh). 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 $6,384 behind.
Electric resistance heat in Champaign, compared
Not every home in Champaign has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,478 a year comes back this way, enough that the 5.4-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Champaign ranks in this dataset
Champaign lands at position 1117 out of 3206 cities on heating severity (coldest is 1), and 380 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Where Champaign's figure comes from
Every constant behind this page — the 2.68 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Champaign'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.
