Will a heat pump pay off in Schaumburg, IL?
Schaumburg is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Schaumburg 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. The heat pump would cost about $240 more a year to run than the furnace it replaces — a premium with no payback. That's Schaumburg's own climate and rates talking, not a hedge or a caveat.
Schaumburg's weather, in the numbers that matter
Schaumburg has a real but manageable winter — 4837 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1162 cooling degree days. Sizing runs off the design temperature, not the average day: -5.1°F here (record low -9.9°F), which works out to a seasonal COP of 2.58 for the cold-climate class of unit this climate calls for. Schaumburg 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.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,747 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,094 a year. Schaumburg's gas rate of 11.25 per Mcf, applied to the 50 Mcf a year the furnace burns, puts its running cost near $854 a year, against 19.06¢ per kWh for electricity. 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 $7,099 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Schaumburg — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Schaumburg's answer improves. About $1,528 a year comes back this way, enough that the 5.2-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Schaumburg ranks in this dataset
Schaumburg lands at position 903 out of 3206 cities on heating severity (coldest is 1), and 490 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.
Next step for 77,099 people in Schaumburg
Schaumburg, Illinois is home to about 77,099 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 Schaumburg, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Schaumburg's 2.58 seasonal COP and payback figure. At a -5.1°F design temperature, Schaumburg sits in cold-climate territory; the guide to that class of unit explains why.
