Claiming Illinois Heat Pump Rebates Through Your Utility

Your contractor bill is where ComEd and Ameren Illinois each apply their discount directly. There is no rebate form to mail once the work is done. ComEd Home Heating & Cooling Discounts require units that hit the SEER2 and HSPF2 minimums, the efficiency ratings shown on the label.

  1. Use a ComEd contractor trained on heat pumps. Equipment you install yourself cannot get the air source or mini-split discounts.
  2. Complete your 2026 install by December 31, 2026, and the contractor can take up to $2,000 off your invoice.
  3. Before work starts, have a certified geothermal specialist secure pre-approval, which the $6,000 ground source incentive requires.

To use Ameren Illinois Instant Incentives, you need either a Program Ally contractor or an installer that buys through a participating distributor. For up to two units per account, the contractor takes the $900 ducted discount or the $630 ductless one off at purchase.

State Rebates and Free Equipment for Lower-Income Households

You can apply to ComEd Whole Home Electric as a qualifying homeowner, provided household income does not exceed 80% of area median income. The local midpoint income for your family size is called area median income; for four people around Chicago it is $95,900. For single-family customers, both the air source heat pump and the heat pump water heater are free. To schedule your screening and assessment, call ComEd or complete the online enrollment form.

Funding for 2026 is already full for homes heated with natural gas. Homes that currently heat with propane or electricity may still apply.

Illinois Home Energy Rebates will receive $263 million in separate federal money, which also aims at households below the 80% income limit. Neither the HEAR appliance program nor the HOMES whole-home pilot pays retroactive rebates; both are still awaiting federal approval.

Federal Tax Rules, Heating Fuels, and Weatherization Help

The Illinois Home Weatherization Assistance Program is run by local agencies and puts up to $20,000 per home into weatherization and repairs. To take part, your total household income cannot exceed 200% of the federal poverty level, which works out to $66,000 for a family of four.

Natural gas heats almost three-quarters of homes in Illinois, while only one in five heats with electricity. Even so, electric air conditioning already runs in 96% of homes across the state. A ducted heat pump can work alongside your current furnace, or you can go all-electric and pay a lower ComEd delivery rate. More nuclear power is generated by Illinois than by any other state: it produces one-eighth of the nation's total.

Public Law 119-21 ended the federal Section 25C credit for any equipment installed after December 31, 2025.

Common Questions About Illinois Heat Pump Rebates

Can I still claim the federal heat pump tax credit in 2026?

No, the credit ended early, as the Internal Revenue Service confirmed in August 2025 with Fact Sheet FS-2025-05. Signed in July 2025, Public Law 119-21 removed the credit for any property put in service after December 31, 2025. In 2026, a new heat pump cannot count on federal tax credits; the savings must come from electric utility discounts.

Which other incentives for heat pumps exist in Illinois?

For a heat pump water heater with the ENERGY STAR label, ComEd pays up to $750, plus $75 for an installed smart thermostat. There is also a $200 appliance rebate from ComEd for a heat pump clothes dryer, and income-eligible households can get $400 instead. Heat pump water heaters come with an Ameren Illinois discount of $1,150 through a contractor, or you can get $800 off at Lowe's and The Home Depot.

How will the size of my equipment change my Illinois heat pump discount?

System size is found when ComEd divides heating capacity, in British thermal units per hour, by 12,000, giving the heating tons. Efficiency determines whether ducted units under 2.5 tons get up to $900 or up to $1,500, and larger systems qualify for $1,400 or $2,000. For ductless systems under 1.5 tons, the amount is up to $500 instead of $1,000, and ComEd permits discounts on more than one unit.

How do I get a free heat pump or free energy upgrades in Illinois?

Whole Home Electric still offers a free heat pump to single-family ComEd customers who heat with propane or electricity. Owners of multifamily buildings can join the same program if they meet the 80% income rule, though they pay a partial co-pay. The ComEd Single Family Home Energy Savings program also installs energy-saving products at no cost, and the products themselves are free.

Get Illinois installer quotes with the rebates taken off

Most rebates on this page are paid through the installer or need the installer's paperwork, so the quote is where the money is settled. Tell us the ZIP code and what you want installed, and installers who work with these programs send a written price with the rebates taken off.

You consent to up to three heat pump installers, or one firm that pairs homeowners with installers, in your ZIP code reaching you about this project by call, text or email at the number and address you entered when you send this request, and those calls and texts may be placed with automated dialing technology. Agreeing is not a condition of any purchase or rebate.
