Illinois Heat Pump Rebates
Stackable incentives available to Illinois homeowners installing a qualifying heat pump in 2026.
Rebate data is re-verified against primary sources every two months.
What's available in Illinois
Illinois has no statewide heat pump rebate funded by state appropriation, and the federal rebates are not yet available either. ComEd and Ameren Illinois run the largest investor-owned utility programs, offering instant point-of-sale discounts for ducted, ductless, and ground-source heat pumps plus heat pump water heaters. The Illinois EPA's IRA Section 50122 HEAR program has NOT launched — the agency's own status page states its application has not yet been processed by USDOE or provided to Illinois EPA for administration or distribution, and the Section 50121 HOMES program remains a pending pilot with two local administering agencies awaiting USDOE approval. No launch date has been announced, so treat the $8,000 income-qualified figure as future-state. Municipal and cooperative utilities add their own rebates — Naperville's municipal electric utility pays up to $1,800 on a tiered schedule, subject to available funding.
HEEHRA in Illinois
HEEHRA rebate: Point-of-sale rebate up to $8,000 for households at or below 80% of area median income. Funded by the IRA, administered by each state. Illinois is finalizing program rules.
How heat pump rebates work in Illinois
Illinois has no state-funded heat pump rebate program; all 2026 rebates come either from utility Act-style efficiency programs or from the federal IRA Home Energy Rebate Programs administered by the Illinois EPA Office of Energy. The two large investor-owned utilities — ComEd in northern Illinois (the Chicago metro plus much of central/northwestern Illinois) and Ameren Illinois in central and southern Illinois — operate the largest residential heat pump programs. Both pay rebates as upfront point-of-sale instant discounts when the install is performed by a participating contractor, which means you never see the full sticker price.
ComEd's residential heat pump discount is tiered by efficiency and tonnage: $900 to $2,000 for qualifying ducted air-source heat pumps and centrally ducted mini-splits (SEER2 under 17 vs 17 and above, under 2.5 tons vs 2.5 and above), with $75 more when bundled with a smart thermostat. Ductless and mixed-use mini-splits sit in a lower $500 to $1,000 band, and ComEd pays up to $6,000 for a ground-source system. Ameren Illinois pays $900 for ducted air-source heat pumps, $630 for ductless mini-splits, and $1,150 for heat pump water heaters (all as instant discounts). Smaller cooperative and municipal utilities — Eastern Illini Electric Cooperative, Naperville's municipal utility, Springfield's CWLP, and others — run their own programs with smaller amounts, generally $200-$500. Whether you can stack a co-op rebate depends on whether your address is in the co-op's territory or an IOU's; the two don't overlap.
The Illinois EPA HEAR program (the state-administered IRA Section 50122 funding) is income-qualified, offering up to $8,000 for households at or below 80% AMI for a heat pump install, with a smaller tier for 80-150% AMI. It has not launched. As of August 2026 the Illinois EPA's own status page states that its Section 50122 application has not yet been processed by the US Department of Energy or provided to Illinois EPA for administration or distribution, and the companion Section 50121 HOMES program remains a pending pilot with two local administering agencies awaiting DOE approval. No launch date has been announced. Treat the $8,000 figure as future-state and budget your 2026 project on utility discounts alone. The federal §25C and §25D credits were both repealed effective December 31, 2025 and do not apply to 2026 installs.
Illinois rebate programs
ComEd Residential Heating and Cooling Heat Pump Discount
$2,000Tiered instant discount, not a flat amount. Ducted and centrally-ducted mini-split heat pumps pay $900-$2,000 depending on SEER2 tier (under 17 vs 17 and above) and tonnage (under 2.5 vs 2.5 and above), with an extra $75 when bundled with a smart thermostat. Ductless and mixed-use mini-splits are a separate, lower tier at $500-$1,000. The $2,000 figure shown here is the ducted ceiling. Applied on the invoice by a ComEd-participating contractor; ComEd does not currently offer a residential heat pump water heater incentive.
Ameren Illinois Ducted Air-Source Heat Pump Instant Discount
$900Upfront point-of-sale discount for Ameren Illinois electric customers when a qualifying ducted air-source heat pump is installed by a participating Program Ally contractor.
Ameren Illinois Heat Pump Water Heater Instant Discount
$1,150Upfront discount for installing a qualifying ENERGY STAR heat pump water heater for Ameren Illinois residential electric customers.
ComEd Ground Source (Geothermal) Heat Pump Discount
$6,000Up to $6,000 per home for a ground-source (geothermal) heat pump system, plus up to $1,200 per unit for geothermal indoor replacement equipment. ComEd service territory (northern Illinois including Chicago).
Ameren Illinois Ductless Mini-Split Heat Pump Instant Discount
$630$630 instant discount for a ductless mini-split heat pump, applied at point of sale through a participating contractor. Separate from Ameren's $900 ducted air-source discount.
City of Naperville Air Source Heat Pump Rebate
$1,800Naperville municipal electric utility. Three tiers: $900 at SEER2 15.2 or above (ducted or ductless); $1,400 at SEER2 17 or above when an existing gas furnace or boiler is retained as backup; $1,800 at SEER2 17 or above with no gas backup. Minimum 8.1 HSPF2, residentially sized (65,000 Btu/hr or less), one rebate per household, applied through the city's GOVQA portal within 120 days of installation. Funding-limited: on 6/26/26 the city announced it had awarded 100% of its $280,000 Renewable Energy Program budget and closed the insulation, window, solar, AC tune-up and blower-motor programs for the rest of 2026; the heat pump program was not on that closed list and its page still accepts applications, but confirm availability before purchase.
Ameren Illinois Ground Source (Geothermal) Heat Pump Instant Discount
$5,400Instant point-of-sale discount of $1,350 to $5,400 for a qualifying closed-loop water-to-air ground-source heat pump installed by a participating Program Ally, plus an additional $500 when a desuperheater is included. Unit must be ENERGY STAR certified, multi-stage or part-load capable, with an ECM blower; limit two per account, Ameren Illinois electric customers only. The $5,400 shown is the top tier before the desuperheater adder.

A worked example: replacing a Chicago electric resistance system
Robert owns a 1,650 sq ft single-family home in Oak Park, served by ComEd. His 1985-era electric baseboard heat is brutal in winter — December and January bills regularly hit $480. His central AC is a 1990s system at end of life. He gets quotes for a 3.5-ton ducted air-source heat pump (16.5 SEER2 / 8.7 HSPF2) replacing both the baseboard heat and the AC, including new ductwork in unfinished spaces. Installed quotes range $19,200 to $23,500; he picks a ComEd-participating contractor at $20,800.
ComEd's residential heat pump discount for a 3.5-ton system at 16.5 SEER2 / 8.7 HSPF2 lands around $1,400 — the SEER2-under-17 tier at 2.5 tons or above, not the program cap. Pushing to a SEER2 17-or-above unit would move him into the $2,000 tier, and bundling a smart thermostat adds $75. Because Robert is replacing electric resistance heat (not gas), some ComEd promotional periods add a 'fuel switching' bonus — verify with the contractor whether that's currently active. The discount appears as a line item on his contractor's invoice, so his net price drops to roughly $19,400.
Robert's household income (around $95,000 for a family of three) puts him at roughly 110% of Cook County AMI — above the 80% threshold for Illinois HEAR's most generous tier. In any case Illinois HEAR has not launched — the Illinois EPA is still waiting on DOE to process the state's application — so there is no HEAR money to add in 2026 at any income tier. His stack is the $1,400 ComEd discount.
Robert's daughter in Champaign is on Ameren Illinois, not ComEd. The same install would qualify under Ameren's $900 ducted ASHP rebate — about $500 less than ComEd's program. Ameren also runs a separate $1,150 heat pump water heater discount; if she added an HPWH to the project, her stack would be $2,050 vs Robert's $1,400 (assuming Robert doesn't add an HPWH). The Illinois lesson: utility identity matters, and bundling water heater work with the HVAC project unlocks additional rebate dollars in Ameren territory.
Choosing a contractor in Illinois
Illinois does not have statewide HVAC contractor licensing. Local jurisdictions (Cook County, City of Chicago, Naperville, and others) license HVAC contractors at the municipal level, and refrigerant work requires EPA Section 608 certification. For Chicago installs, your contractor must hold a Chicago HVAC License (issued by the Department of Buildings); for suburban Cook County, county-level licensing applies. Verify licensing at the relevant city or county building department before signing.
ComEd's residential heat pump discount and Ameren Illinois's instant discount both flow through Program Ally (Ameren) or participating contractor (ComEd) networks. A non-enrolled contractor cannot file the rebate after the fact — these are point-of-sale programs, not reimbursement programs. Ask before signing: 'Are you currently enrolled with [ComEd / Ameren] as a participating heat pump contractor, and will the discount appear on my invoice?'
Illinois winters are cold — Chicago design temperature is roughly -5°F, Rockford and Peoria similar. A non-cold-climate heat pump can struggle below 10°F and trigger expensive electric resistance backup. For installs in northern and central Illinois, specify a NEEP Cold-Climate Air-Source Heat Pump Specification (CCASHP) listed system. Some ComEd rebate tiers step up explicitly for cold-climate certified equipment; ask your contractor whether the rebate amount changes between standard and cold-climate models.
Common pitfalls for Illinois homeowners
- Confusing ComEd and Ameren territories. ComEd serves the Chicago metro and parts of northern Illinois; Ameren Illinois serves central and southern Illinois. The two utilities don't overlap, and their rebate programs are separate. A homeowner who moves between territories needs to recheck — your previous utility's program doesn't follow you.
- Assuming Illinois HEAR is open everywhere. Illinois HEAR has not launched at all. The Illinois EPA's own status page says its Section 50122 application has not yet been processed by the US Department of Energy or handed to the agency to administer, and HOMES is still a pending pilot awaiting DOE approval. Any contractor quote that promises HEAR money against a 2026 Illinois install is quoting a program that isn't accepting applications anywhere in the state. The Illinois EPA Office of Energy's page is the authoritative status source.
- Skipping the participating contractor requirement. Both ComEd and Ameren rebates are point-of-sale through participating contractors. A homeowner who hires a non-participating contractor cannot retroactively claim the rebate — there is no 'post-install reimbursement' pathway for these programs. The cheapest quote sometimes comes from a non-participating contractor; the apparent savings disappear when you account for the lost rebate.
- Counting on §25C federal credit. The federal residential energy property credit (§25C) covered up to $2,000 for heat pumps in 2025 but was repealed effective December 31, 2025 by the OBBBA. Illinois installs completed in 2026 cannot claim it. The §25D 30% federal geothermal credit was also repealed effective December 31, 2025, so no federal tax credit applies to 2026 installs.
- Underestimating Chicago electric panel constraints. Many older Chicago and Cook County homes have 100A or 60A electrical service. A whole-home heat pump replacing electric baseboard or oil heat can push the home over panel capacity, requiring a $2,000-$5,000 panel upgrade as a prerequisite. Illinois HEAR (when available) covers panel upgrades as a separate measure; ComEd does not. Ask your contractor for a panel-capacity assessment as part of the quote.

How to claim each rebate
- Get pre-approved (where required). Some utility programs require approval before install. Check program details before signing a contract.
- Use a participating contractor. Many programs require a licensed installer from an approved contractor list — especially HEEHRA, which routes through CEC-approved contractors who process the rebate at point of sale.
- Save documentation. AHRI certificate, model numbers, and itemized invoice are required for most utility rebates.
- Submit utility rebate within 60–90 days of install. Some programs are first-come first-served and close mid-year — funding can run out before the calendar year does.
If you can't afford a replacement in Illinois
Rebates lower the price, but they still assume you can pay the rest. If your heating system is unsafe or has failed and a new one is out of reach, these programs repair or replace equipment at low or no cost for income-qualified households. Heat Pump Pricing Index is an independent information site — we don't fund, discount, or install equipment — so these are the doors to knock on first:
- Weatherization Assistance Program (WAP). Free energy and health-and-safety repairs — an unsafe furnace is exactly the kind of problem it fixes — for households at or near 200% of the poverty line. Apply through your local community action agency: how to apply (energy.gov).
- LIHEAP. Heating-bill help plus, in most states, a crisis component for broken or dangerous heating equipment. Same local agency; Illinois LIHEAP contacts.
- USDA Section 504 Home Repair. For homeowners outside cities: 1% loans up to $40,000, and grants up to $10,000 for homeowners 62 and older to remove health and safety hazards. Program page and state offices (rd.usda.gov).
- Your utility and 211. Most electric and gas utilities run an income-qualified assistance fund — call the number on your bill and ask. Dialing 211 reaches a local specialist who knows which agencies in Illinois currently have funds.
Safety first: if a technician has told you a heat exchanger is cracked, stop using the furnace and make sure you have a working carbon monoxide detector before anything else.
