Utility programs in Illinois

These are the named utility and ratepayer rebates on file for Illinois. You claim the one that serves your address, not the total. Each card carries the program’s own terms: what equipment qualifies, who is eligible, what the cap actually is, and whether it stacks.

This one is already inside your quoted price. A participating contractor takes it off at the point of sale, so do not budget for it a second time as money arriving later.

What your system should be sized for

A heat pump in Illinois should carry the house on the coldest design day, not the average one. These are the winter design temperatures our engine sizes against, in AHRI heating region V (6,300 heating degree days at the Chicago reference metro).

Eligibility varies by income, equipment efficiency, utility territory, and program funding availability.
