Heat Pump Payback in Aurora, IL
Heat pump vs. gas furnace in Aurora, IL
Here in Aurora, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Running costs here land $339 a year higher than the furnace it replaces, so that premium is never recovered. There's no spin on that: Aurora's numbers say wait.

Why Aurora's climate drives this number
Aurora has a cold winter that leans hard on heating equipment, 5330 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 868 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is -9°F, and the coldest daily reading in the 2024 station record was -15°F. That puts the seasonal coefficient of performance at 2.48 for the recommended cold-climate unit. A cold-climate unit is the right call in Aurora, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from Aurora Municipal Airport, the closest NOAA station, 9.8 miles out.
Aurora's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 5,442 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,178 a year. Aurora's gas rate of $11.25 per Mcf, applied to the 56 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $839 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 $10,591 behind.
What would change Aurora's answer
The heat pump would become the cheaper option in Aurora if electricity fell to 12.3¢/kWh (from 19.06¢) or gas rose above $17.36 per Mcf (from $11.25). At today's prices a cheaper quote cannot rescue the gas comparison in Aurora, since there is no yearly saving to recover it from.
If your home heats with electric baseboard instead of gas
Plenty of homes in Aurora heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Aurora's answer improves. Switching saves about $1,608 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 6.2 years.
Aurora against the rest of the country
Ranked against the other 3206 cities covered, Aurora comes in at 454 for heating severity, 1 would be the coldest place in the dataset, and 147 by population, where 1 is largest. 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 Aurora
About 180,710 people live in Aurora, 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.

Where Aurora's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Aurora's 2.48 seasonal COP and payback figure. Aurora's -9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
