Nicor Gas Energy Efficiency Loans for Homeowners
Run by Energy Finance Solutions (EFS), program lender for Nicor Gas
Nicor Gas customers who own a home of up to four units can borrow $500 to $20,000 at a fixed rate for rebate-eligible efficiency upgrades, repaid on the monthly gas bill.
Amounts

Applying
How to apply
Get approved before you buy anything.
