Heat pump vs. gas furnace in Hinsdale, IL
Hinsdale 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. The heat pump would cost about $151 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Hinsdale's numbers say wait.
Why Hinsdale's climate drives this number
4543 heating degree days pile up here every year, so Hinsdale has a real but manageable winter; the cooling side runs to 1348 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: 1.9°F here (record low -9°F), which works out to a seasonal COP of 2.75 for the cold-climate class of unit this climate calls for. Hinsdale 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. These numbers come from CHICAGO MIDWAY INTL ARPT, the closest NOAA station, 9.1 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 4,183 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,016 a year. Hinsdale's gas rate of 11.25 per Mcf, applied to the 47 Mcf a year the furnace burns, puts its running cost near $865 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 $5,767 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Hinsdale 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. Switching saves about $1,509 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 5.3 years.
Where Hinsdale ranks in this dataset
Among 3206 cities, Hinsdale's winter puts it at rank 1159 for severity, while its size puts it at rank 2130 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Hinsdale's 2.75 seasonal COP and payback figure. Hinsdale's 1.9°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.
