Rebate Details
Overview
The Nicor Gas Exterior Wall Insulation Rebate provides $150 per home for qualifying exterior wall insulation upgrades. Offered by Nicor Gas as part of their residential Energy Efficiency Program, this incentive targets homes in their northern Illinois service area. It focuses on exterior walls where existing insulation is minimal (R5 or less). The program runs through December 31, 2026, for installations.
How It Helps You
Adding insulation to exterior walls reduces heat loss in winter and heat gain in summer, often cutting energy bills by 10-20% depending on your home’s size, climate, and other upgrades. You’ll enjoy more consistent indoor temperatures, fewer drafts, and greater comfort year-round. This rebate lowers upfront costs, and it can stack with the federal Inflation Reduction Act home energy efficiency credits for even more savings. Environmentally, better insulation means less natural gas used for heating, reducing your household’s carbon footprint.
Pros and Cons
- Pros: Straightforward $150 savings; pairs well with required air sealing for bigger overall gains; improves home value and comfort.
- Cons: Requires prior air sealing and an approved contractor; involves paperwork and photo submissions.

Real-World Examples
- A homeowner in a Chicago suburb with an older home and low wall insulation adds exterior wall insulation after air sealing. They get $150 back, plus ongoing savings of $200-400 annually on heating bills in Illinois winters.
- Combining this with Nicor Gas attic insulation ($400) and air sealing ($500) rebates, a family could claim over $1,000 total while making their home noticeably warmer and more efficient.
