Illinois Heat Pump Rebates 2026

In Illinois, a whole-home air-source heat pump typically costs $5,000–$14,000 installed, depending on home size, system type, and contractor. Cold-climate models for zones like Zone 5A cost more but deliver lower operating costs. Combined rebates of up to $600 (state programs) can offset a significant portion of installed cost.

Illinois's HEEHRA program has not yet launched but is expected to open. Illinois HEEHRA (the Home Electrification and Appliance Rebate / HEAR program) has NOT yet launched. As of June 2026 the Illinois EPA reports the program is pending US DOE approval and is not accepting applications; independent trackers expect a spring 2026 launch. When live, income-qualified households (≤150% AMI) will be eligible for up to $8,000 for a heat pump. Until then, ComEd and Ameren utility rebates are the active incentives. Verify status at epa.illinois.gov before counting on HEAR funds. Check your state energy office for updates. Note: the federal IRA 25C tax credit expired December 31, 2025 and is not available for new 2026 installations.

Illinois falls in IECC 2021 Zone 5A — Cool-Humid. Typical winter design temperatures are 0°F to 15°F. Cold-climate ASHP required (Mitsubishi Hyper-Heat, Bosch IDS, Daikin Fit, etc.). Size for outdoor design temperature, not average. Sizing requires a Manual J load calculation — but as a rough rule, allow 20–30 BTU/h per square foot for older homes in Illinois.

Not necessarily. Most 200A panels in Illinois have headroom for a heat pump under the NEC 220.82 Optional Method — which accounts for diversity of loads rather than peak simultaneous demand. A 100A panel is more likely to require an upgrade, especially if you also have an EV charger or electric range. Our free audit calculates your exact available capacity in 3 minutes using the same method your electrician would use.

Illinois rebates are split by utility territory. ComEd (Commonwealth Edison) serves northern Illinois including the Chicago metro and offers up to $500 for qualifying ENERGY STAR heat pumps. Ameren Illinois serves central and southern Illinois and offers up to $600. You qualify for one or the other based on your address, not both. Both require ENERGY STAR-rated equipment — verify current amounts and any contractor requirements on your utility's rebate page before purchasing.

Not yet. As of June 2026, the Illinois EPA reports that the Home Electrification and Appliance Rebate (HEAR) program — the federal income-qualified rebate worth up to $8,000 for a heat pump — is pending US Department of Energy approval and is not accepting applications. Independent trackers expect a 2026 launch. Be cautious of any contractor or website claiming the $8,000 Illinois rebate is live today — it is not. Until HEAR launches, ComEd and Ameren utility rebates are the active Illinois incentives. Check epa.illinois.gov for the current status.

Yes. Illinois is IECC Zone 5A, and Chicago-area winter design temperatures fall well below freezing, so a cold-climate-rated (ccASHP) heat pump is necessary for reliable performance through the coldest stretches. Standard heat pumps lose too much capacity at these temperatures and may rely heavily on backup resistance heat, raising operating costs. Pair a cold-climate unit with a Manual J load calculation to size it correctly and confirm your backup-heat strategy.

It depends on which utility delivers your electricity. ComEd covers northern Illinois (Chicago and the surrounding metro, plus much of the northern third of the state) and offers up to $500. Ameren Illinois covers central and southern Illinois and offers up to $600. Your electric bill shows which utility you are served by. You cannot claim both — apply to the one that serves your address, and confirm current amounts on their rebate page before buying equipment.
