Will a heat pump pay off in Belvidere, IL?
Belvidere is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Belvidere would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Unfortunately the electric bill outweighs the gas bill it replaces by about $350 a year here, so the extra spend stays unrecovered. There's no spin on that: Belvidere's numbers say wait.
The climate behind Belvidere's payback figure
Degree days tell the story here: Belvidere racks up 5277 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 898 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -11°F, against a record low of -16.1°F. That puts the seasonal coefficient of performance at 2.44 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Belvidere sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from GREATER ROCKFORD AIRPORT, the closest NOAA station, 11.6 miles out.
The month-to-month numbers for Belvidere
A 2000-square-foot house here would pull roughly 5,476 heating kilowatt-hours annually on top of cooling, totalling about $1,190 a year on electricity. The gas furnace it replaces burns roughly 55 Mcf a year at 11.25 per Mcf here, for a running cost near $840 a year (electricity here runs 19.06¢/kWh). Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $8,744 behind.
If your home heats with electric baseboard instead of gas
Plenty of homes in Belvidere heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,579 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 5.1 years.
Where Belvidere ranks in this dataset
Ranked against the other 3206 cities covered, Belvidere comes in at 523 for heating severity — 1 would be the coldest place in the dataset — and 1583 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Every constant behind this page — the 2.44 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Belvidere's -11°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.
