Illinois Energy Rebates 2026

Illinois homeowners can access HEAR rebates up to $14,000 and HOMES rebates up to $8,000 through DCEO, though both programs are pending full launch as of mid-2026. Already active: ComEd customers in northern Illinois can use utility rebates up to $1,675 on heat pumps and $75 on smart thermostats. Ameren Illinois customers in central and southern Illinois can receive $900 off a ducted heat pump and $800 off a heat pump water heater through the Ameren Illinois Energy Efficiency Program.

No. The 25C Energy Efficient Home Improvement Credit and the 25D Residential Clean Energy Credit both expired on December 31, 2025 under the One Big Beautiful Bill Act. Illinois homeowners can no longer claim these credits for 2026 installations. Focus instead on HEAR, HOMES, and utility rebates from ComEd or Ameren Illinois when those programs launch.

ComEd's utility-funded Energy Efficiency Program runs year-round and is active now. Northern Illinois residential customers can receive up to $1,675 on qualifying ducted air source heat pumps, up to $1,000 on ductless mini-splits, up to $6,000 on geothermal systems, $75 on ENERGY STAR smart thermostats, and rebates on insulation and duct sealing. Income-eligible customers qualify for enhanced rebate amounts. Visit comed.com/rebates for current amounts.

Illinois HEAR rebates target households earning up to 150% of Area Median Income (AMI), with the highest rebate tiers for those at or below 80% AMI. In the Chicago-Naperville-Elgin metro area, 80% AMI for a 4-person household is approximately $85,600. In Springfield, 80% AMI is about $69,600. Contact EPA.EnergyRebates@Illinois.gov to check your specific eligibility once the program fully launches.

IHWAP is a separate income-restricted program funded by federal weatherization dollars, providing free insulation, air sealing, and heating system upgrades for households at or below 200% of the federal poverty level -- with up to $20,000 in improvements per home. IHWAP and HEAR/HOMES can complement each other: IHWAP handles building envelope improvements, while HEAR covers appliance electrification like heat pumps and electric stoves. Contact your local Community Action Agency to apply for IHWAP.

Ameren Illinois's Energy Efficiency Program serves customers in central and southern Illinois with instant discounts and mail-in rebates: $900 off a ducted air source heat pump, $630 off a ductless mini-split, an $800 retail rebate (or $1,150 contractor discount) on an ENERGY STAR heat pump water heater, and a $100 rebate on an ENERGY STAR smart thermostat. Rebates require purchase by December 31 and submission within 60 days of purchase. Visit amerenillinoissavings.com for full product lists and participating contractors.

Yes. Utility rebates from ComEd or Ameren Illinois can be layered with federal HEAR rebates, as long as each rebate applies to an eligible measure and the combined total does not exceed your actual project cost. When Illinois HEAR fully launches, coordinate with a certified contractor to identify the best stacking strategy -- ComEd or Ameren Illinois rebates plus HEAR can reduce your out-of-pocket costs significantly on heat pump and insulation upgrades.

Illinois homeowners have three main insulation rebate options. ComEd offers insulation and duct sealing rebates for northern Illinois customers -- visit comed.com/rebates for current amounts. The HEAR program will offer up to $1,600 for insulation, air sealing, and ventilation combined once fully launched in Illinois. IHWAP provides free insulation and air sealing for income-eligible households (at or below 200% of the federal poverty level) through local community action agencies, with up to $20,000 in total improvements.

As of mid-2026, Illinois HEAR and HOMES programs are not yet fully operational -- HOMES is in a pilot phase with select local agencies and HEAR is awaiting final U.S. DOE approval. To stay current, sign up for updates at epa.illinois.gov/topics/energy/energy-rebates or email EPA.EnergyRebates@Illinois.gov. Once launched, applications will be submitted through DCEO-approved local administering agencies after a qualifying energy assessment by a certified contractor.

Illinois Solar for All is available to households with income at or below 80% of the Area Median Income (AMI) for their county. The program offers free or subsidized community solar subscriptions, eliminating the need for rooftop installation. Single-family residential capacity was filled in 2025; a waitlist exists for the 2026-27 cycle. Contact illinoissolarforall.com to join the waitlist and verify your county's AMI limits.
