Will a heat pump pay off in Chicago Heights, IL?
Here in Chicago Heights, 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 $3,500 more up front here (already netting out a $2,000 tax credit). Running costs here land $278 a year HIGHER than the furnace it replaces, so that premium is never recovered. That's Chicago Heights's own climate and rates talking, not a hedge or a caveat.
How cold Chicago Heights actually gets
Degree days tell the story here: Chicago Heights racks up 4971 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 864 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -5.3°F, against a record low of -10.7°F. That puts the seasonal coefficient of performance at 2.57 for the recommended cold-climate unit. A cold-climate unit is the right call in Chicago Heights — 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 LANSING MUNICIPAL AP, the closest NOAA station, 5.7 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 4,898 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,074 a year. The gas furnace it replaces burns roughly 52 Mcf a year at 11.25 per Mcf here, for a running cost near $796 a year (electricity here runs 19.06¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $7,671 behind.
Electric resistance heat in Chicago Heights, compared
Plenty of homes in Chicago Heights heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,539 a year, which recovers the extra $8,000 spent going electric in roughly 5.2 years.
