Heat Pump Payback in Skokie, IL
Should Skokie switch to a heat pump?
In Skokie, a heat pump would cost more to run each year than what you have now. $5,500 is what Skokie would pay extra to go electric rather than replace the furnace and AC with the same again. Running costs here land $228 a year higher than the furnace it replaces, so that premium is never recovered. There's no spin on that: Skokie's numbers say wait.

The climate behind Skokie's payback figure
4991 heating degree days pile up here every year, so Skokie has a real but manageable winter; the cooling side runs to 1020 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 (coldest 2024 reading -11°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 Skokie, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Skokie's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,716 heating kilowatt-hours annually on top of cooling, totalling about $1,065 a year on electricity. The gas furnace it replaces burns roughly 52 Mcf a year at $11.25 per Mcf here, for a running cost near $837 a year including the old AC (electricity here runs 19.06¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $8,917 behind.
The break-even point in Skokie
The heat pump would become the cheaper option in Skokie if electricity fell to 13.7¢/kWh (from 19.06¢) or gas rose above $15.63 per Mcf (from $11.25). At today's prices a cheaper quote cannot rescue the gas comparison in Skokie, since there is no yearly saving to recover it from.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Skokie, 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 $1,596 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 6.3 years.
Skokie against the rest of the country
Among 3206 cities, Skokie's winter puts it at rank 713 for severity, while its size puts it at rank 598 for population, 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.
What to do with this number in Skokie
About 65,850 people live in Skokie, Illinois, and every number on this page is what a contractor would actually work from when quoting a system here, the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
Ask a local HVAC contractor for a quote before committing either way.
Where Skokie'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. Skokie's -0.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
