ComEd Energy Efficiency Rebates for Illinois Homeowners

ComEd's residential programs are the largest source of efficiency money for homeowners in northern Illinois, and the easiest to get wrong — the offer you read about in a contractor's flyer is often last year's version. Here is how the program is actually structured.

Active — offers change yearly

Specific offers, amounts and eligible equipment lists are updated by ComEd. Confirm the current offer on its live page before purchasing anything.

Administered by Commonwealth Edison (ComEd), under Illinois efficiency program rules. Last reviewed November 6, 2026.

Independent guidance — Illinois RDN is not a government agency and does not administer these programs.

Who it is for

  • You must be a ComEd residential customer; the program follows the service territory, not the county line.
  • Equipment must appear on the current qualified-products list for the offer you are claiming — a highly efficient unit that is not on the list does not qualify.
  • The purchase or installation must fall inside the offer's current date window.
  • Some offers require a participating contractor; others are point-of-sale discounts at a retailer.

What it covers

  • Heat pump and HVAC equipment incentives, including efficiency-tier requirements.
  • Insulation and air-sealing incentives, often delivered through a participating contractor.
  • Smart thermostats and select appliances, frequently as an instant discount.
  • Home energy assessments that identify what the house needs before equipment is chosen.
  • A separate income-qualified track for households that meet the program's income test.

How to apply

  1. 01
    Confirm the current offer

    Start on ComEd's live incentives page. Match the exact equipment category, then note the efficiency threshold it requires.

  2. 02
    Check the purchase window

    Rebates apply to purchases inside a stated period. Buying before the window opens, or after it closes, forfeits the incentive.

  3. 03
    Choose the delivery route

    Decide whether the offer is an instant discount at purchase or a rebate application afterward — they require different paperwork from you.

  4. 04
    Keep the documents

    Save the invoice, model and serial numbers, and proof of installation. Missing model numbers are the most common reason a rebate application is rejected.

  5. 05
    Ask about the income track

    If your household is income-qualified, ask whether the income-qualified offer is larger than the standard one before you buy.

What to have ready

  • Itemized invoice showing the equipment model and installation date.
  • Model and serial numbers for the installed equipment.
  • Proof of ComEd service at the installation address.
  • Contractor information if the offer requires a participating contractor.

Where homeowners get stuck

  • Quoting a number from an old flyer. Offers are revised; the live page is the only current source.
  • Assuming any high-efficiency unit qualifies — the qualified-products list is specific.
  • Missing the purchase window by installing during a gap between program years.
  • Overlooking the income-qualified track, which can be substantially better for eligible households.

How it combines with other programs

Utility rebates can often be combined with weatherization work, but not for the same measure twice. If IHWAP installs attic insulation, do not also claim a ComEd insulation rebate for it.

Questions homeowners ask

Can I claim a ComEd rebate on a DIY installation?

It depends on the offer. Some equipment rebates accept self-installed products with receipts; insulation and HVAC offers usually require a participating contractor. Check the specific offer's requirements.

Does the rebate go to me or the contractor?

Either can happen. Instant discounts are taken off the invoice by the contractor or retailer; rebate applications are paid to the applicant. Ask which structure you are getting before signing.

What if my contractor is not on the list?

You may still qualify for a mail-in rebate, but not for contractor-delivered offers. Confirm with ComEd before the work, not after.

Is this the same as Illinois EPA rebates?

No. ComEd's programs are utility efficiency programs. The state-level HEAR and HOMES rebates are separate federal-funded programs with their own status.
