Will a heat pump pay off in Matteson, IL?
In Matteson, a heat pump would cost more to run each year than what you have now. 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 $278 more a year to run than the furnace it replaces — a premium with no payback. That's Matteson's own climate and rates talking, not a hedge or a caveat.
How cold Matteson actually gets
4971 heating degree days pile up here every year, so Matteson has a real but manageable winter; the cooling side runs to 864 cooling degree days, where summers add a moderate cooling load. -5.3°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -10.7°F on file. Worked through the model, that's a seasonal COP of 2.57 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Matteson — 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, LANSING MUNICIPAL AP, 11.3 miles from Matteson.
The month-to-month numbers for Matteson
A 2000-square-foot house here would pull roughly 4,898 heating kilowatt-hours annually on top of cooling, totalling about $1,074 a year on electricity. That compares with roughly 52 Mcf a year of gas at Matteson's 11.25 per-Mcf rate — about $796 a year — against a local electricity rate of 19.06¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $7,671 behind.
The other scenario: no gas furnace to begin with
Not every home in Matteson has gas service. Swap the comparison to resistance heat instead of gas, and Matteson's answer improves. About $1,539 a year comes back this way, enough that the 5.2-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Matteson ranks in this dataset
Among 3206 cities, Matteson's winter puts it at rank 773 for severity, while its size puts it at rank 2046 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.
