Rebate Snapshot
Overview
The Nicor Gas Attic Insulation Rebate provides $400 per home to qualifying residential customers who upgrade their attic insulation. Offered by Nicor Gas (a natural gas utility in northern Illinois), this incentive encourages weatherization to lower heating costs.
Key details:
- Rebate amount: $400 flat per home (limited to one per household).
- Types covered: Attic insulation.
- Requirements: Must follow air sealing (separate $500 rebate available), start with existing R-value of R20 or less, and achieve final R-value of R49 or greater.
- Eligible area: Northern Illinois (all current Nicor Gas residential customers).
- Expiration: Installations qualify through December 31, 2026.
How It Helps You
Adding attic insulation can reduce energy bills by 10-30% depending on your home’s size, current setup, and climate – especially valuable in Illinois winters. You’ll enjoy a warmer home in winter, cooler in summer, fewer drafts, and better comfort year-round.
This rebate lowers upfront costs, and it stacks nicely with the federal Inflation Reduction Act’s energy efficient home improvement credit (up to 30% of costs, potentially thousands more). Environmentally, you’ll reduce natural gas use and your carbon footprint.
Pros: Significant upfront savings, quick payback through lower bills, improved home value. Cons: Requires paperwork, pre/post photos, and using an approved contractor; air sealing must come first.
