Should Roscoe switch to a heat pump?
Roscoe 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 $315 a year here, so the extra spend stays unrecovered. That's Roscoe's own climate and rates talking, not a hedge or a caveat.
Roscoe's weather, in the numbers that matter
5393 heating degree days pile up here every year, so Roscoe has a cold winter that leans hard on heating equipment; the cooling side runs to 828 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: -5.8°F here (record low -14.8°F), which works out to a seasonal COP of 2.56 for the cold-climate class of unit this climate calls for. Roscoe 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.

Roscoe's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 5,334 heating kilowatt-hours annually on top of cooling, totalling about $1,151 a year on electricity. The gas furnace it replaces burns roughly 56 Mcf a year at 11.25 per Mcf here, for a running cost near $836 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 $8,223 behind.
Electric resistance heat in Roscoe, compared
Plenty of homes in Roscoe heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $1,656 a year, which recovers the extra $8,000 spent going electric in roughly 4.8 years.
How Roscoe compares nationally
Roscoe lands at position 435 out of 3206 cities on heating severity (coldest is 1), and 2988 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.
Deciding what's next in Roscoe, IL
Roscoe, Illinois is home to about 10,981 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Roscoe, nothing is lost by holding off until the current equipment genuinely fails.

Every constant behind this page — the 2.56 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Roscoe's -5.8°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.
