General Rebate Questions

Can I apply for a rebate if I do not have a Nicor Gas account number?

Nicor Gas rebates are only available to active Nicor Gas customers within our service area. Your account number is required to receive a rebate, which can be found on your Nicor Gas bill, or by calling 877.886.4239 for assistance. If you are a new Nicor Gas customer and do not have your account number yet, you may still be eligible for select rebates. Contact Us for more information.

What improvements and equipment are eligible for a rebate?

Each rebate application has a summary of qualifying energy efficiency upgrades available, as well as current rebate levels. Review the PDFs on the Current Offers page. You can also find lists of qualifying products on the residential rebates and commercial rebates.

What do I need to mail with my rebate application?

Be sure to read the rebate application carefully to determine what you will need to submit for approval. Rebate applications generally require these materials:

  1. A completed rebate application or confirmation page (when applying online).
  2. A receipt or invoice that includes all applicable information regarding the installation and/or purchase of the qualifying equipment.

However, each rebate application is different, so please review carefully to ensure you provide all the necessary material in order to receive your rebate quickly.

How long does it take to process a rebate?

Please allow six to eight weeks for delivery of the rebate once all necessary documentation is received and approved.

I had several upgrades within a rebate application. Is it OK if I mail them in the same envelope?

Yes. You may mail all documents for multiple products or services covered under a single rebate in one envelope to the address and offer number listed on your rebate application.

I had several upgrades across multiple rebate applications. Is it OK if I mail them in the same envelope?

No. To ensure your applications are processed properly, you must mail each rebate application separately to the specific address and offer number noted on the application.

I have multiple account numbers (service addresses). Can I submit a single rebate for all improvements?

No. You must complete a separate rebate form for each account number and service address.

What is the difference between the installation date and the postmark date?

Your installation date must take place during the program promotional period, January 1, 2022-December 31, 2022. Applications for rebates must be postmarked or completed online within the timeline listed after your installation, usually 90 days.

Why can't I send my rebate application to the same address I sent my Nicor Gas payment?

Your rebate application is reviewed by a dedicated rebate payment center that verifies eligibility of your rebate and processes your application and payment. To ensure you receive your rebate in a timely manner, please send the rebate application with all required documentation to the address that appears on the rebate form.

Where can I find my Tracking ID?

When applying online, your Tracking ID will be located on the confirmation page. If you apply by mail, you will not receive a tracking ID. Instead, you can check the status of your rebate using your Nicor Gas account number.

Who do I contact if I have questions?

If you are applying for or have questions about a rebate, please call 877.886.4239 weekdays, 8 a.m. to 5 p.m. central time or email

How can I get a rebate application if I do not have access to a printer?
