Heat Pump Payback in Homer Glen, IL
Heat pump vs. gas furnace in Homer Glen, IL
Homer Glen is a place where a heat pump genuinely costs more to operate than the alternative. $5,500 is what Homer Glen would pay extra to go electric rather than replace the furnace and AC with the same again. The heat pump would cost about $250 more a year to run than the furnace it replaces, a premium with no payback. There's no spin on that: Homer Glen's numbers say wait.

The climate behind Homer Glen's payback figure
Homer Glen has a real but manageable winter, 4951 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1049 cooling degree days. Sizing runs off the design temperature, not the average day: -4°F here (coldest 2024 reading -13°F), which works out to a seasonal COP of 2.6 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Homer Glen, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, Lewis University Airport, 6.9 miles from Homer Glen.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 4,822 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,090 a year. That compares with roughly 52 Mcf a year of gas at Homer Glen's $11.25 per-Mcf rate, about $839 a year with the old AC included, against a local electricity rate of 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 $9,254 behind.
What would change Homer Glen's answer
The heat pump would become the cheaper option in Homer Glen if electricity fell to 13.3¢/kWh (from 19.06¢) or gas rose above $16.10 per Mcf (from $11.25). At today's prices a cheaper quote cannot rescue the gas comparison in Homer Glen, since there is no yearly saving to recover it from.
If your home heats with electric baseboard instead of gas
Not every home in Homer Glen has gas service. Swap the comparison to resistance heat instead of gas, and Homer Glen's answer improves. About $1,559 a year comes back this way, enough that the 6.4-year payback clears the $10,000 premium comfortably within the equipment's life.
How Homer Glen compares nationally
