Your application paperwork

Nicor Gas offers this rebate to its residential customers who install the qualifying energy-efficient equipment this program covers. You apply through the utility's rebate program, usually online with your account, your paid invoice, and the equipment's model or efficiency rating. Many rebates are submitted by a participating contractor and paid after the equipment is installed, so confirm the current rebate and rules on the official page first.

Steps to apply

  1. Confirm you are a Nicor Gas residential customer and your project uses equipment that meets the program's efficiency requirements.
  2. Check the official rebate page for the current rebate amount, eligible equipment, and whether a participating contractor is required.
  3. Buy and install the qualifying equipment (keep the itemized paid invoice and the equipment model or AHRI / ENERGY STAR information).
  4. Submit the rebate application online within the program's deadline (often the contractor submits it for you), then receive the rebate after approval.
