Rebates & incentives in Illinois
HEAR pendingHeat pumps qualify for the largest 2026 incentives — this is the equipment state and utility rebate programs are built around.
- Illinois Home Energy Rebates (HEAR) ↗Illinois EPA
Not yet live; utility rebates (ComEd, Nicor Gas) are the current path.
Status: Illinois has federal HEAR funding but had not launched its consumer program as of mid-2026 — check ComEd/Nicor utility rebates in the meantime.
The federal 25C tax credit (up to $2,000 for heat pumps; $600 for high-efficiency AC or furnaces) and the 25D credit ended December 31, 2025 under the One Big Beautiful Bill Act — neither is available for 2026 installs. The remaining federal help is the IRA Home Electrification & Appliance Rebates (HEAR): up to $8,000 toward a heat pump for households under 150% of area median income, paid at point of sale where a state has launched its program.
