Heat Pump Payback in Tinley Park, IL
Heat pump vs. gas furnace in Tinley Park, IL
In Tinley Park, a heat pump would cost more to run each year than what you have now. $5,500 is what Tinley Park would pay extra to go electric rather than replace the furnace and AC with the same again. Unfortunately the electric bill outweighs the gas bill it replaces by about $278 a year here, so the extra spend stays unrecovered. There's no spin on that: Tinley Park's numbers say wait.

Why Tinley Park's climate drives this number
4971 heating degree days pile up here every year, so Tinley Park has a real but manageable winter; the cooling side runs to 864 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: -5.3°F here (coldest 2024 reading -10.7°F), which works out to a seasonal COP of 2.57 for the cold-climate class of unit this climate calls for. Tinley Park 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.

The yearly running costs in Tinley Park
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,898 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,074 a year. Tinley Park's gas rate of $11.25 per Mcf, applied to the 52 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $796 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 $9,671 behind.
How sensitive Tinley Park's result is to prices
The heat pump would become the cheaper option in Tinley Park if electricity fell to 12.9¢/kWh (from 19.06¢) or gas rose above $16.62 per Mcf (from $11.25). At today's prices a cheaper quote cannot rescue the gas comparison in Tinley Park, since there is no yearly saving to recover it from.
The other scenario: no gas furnace to begin with
Gas isn't universal in Tinley Park, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Tinley Park's answer improves. Switching saves about $1,539 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 6.5 years.
Where Tinley Park ranks in this dataset
Among 3206 cities, Tinley Park's winter puts it at rank 754 for severity, while its size puts it at rank 746 for population, 1 in both cases being the extreme. 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
Nothing above is a black box: the methodology guide shows the full arithmetic behind Tinley Park's 2.57 seasonal COP and payback figure. Tinley Park's -5.3°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.
