Heat Pump Payback in Addison, IL
Will a heat pump pay off in Addison, IL?
Here in Addison, the honest answer is that a heat pump raises your annual running cost. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Running costs here land $240 a year higher than the furnace it replaces, so that premium is never recovered. There's no spin on that: Addison's numbers say wait.

Why Addison's climate drives this number
4837 heating degree days pile up here every year, so Addison has a real but manageable winter; the cooling side runs to 1162 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is -5.1°F, and the coldest daily reading in the 2024 station record was -9.9°F. That puts the seasonal coefficient of performance at 2.58 for the recommended cold-climate unit. Addison 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. Climate figures trace to the nearest NOAA station, Chicago O'Hare International, 4.4 miles from Addison.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 4,747 heating kilowatt-hours annually on top of cooling, totalling about $1,094 a year on electricity. Addison's gas rate of $11.25 per Mcf, applied to the 50 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $854 a year, against 19.06¢ per kWh for electricity. 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 $9,099 behind.
How sensitive Addison's result is to prices
The heat pump would become the cheaper option in Addison if electricity fell to 13.4¢/kWh (from 19.06¢) or gas rose above $16.01 per Mcf (from $11.25). At today's prices a cheaper quote cannot rescue the gas comparison in Addison, since there is no yearly saving to recover it from.
The other scenario: no gas furnace to begin with
Gas isn't universal in Addison, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,528 a year, which recovers the extra $10,000 spent going electric in roughly 6.5 years.
Addison against the rest of the country
Addison lands at position 909 out of 3206 cities on heating severity (coldest is 1), and 1149 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.

More on how this number was built
The methodology guide walks through exactly how Addison's 2.58 seasonal COP and the rest of this page's numbers get built. Addison's -5.1°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.
