Serving Boone and Winnebago Counties, the Weatherization Program enables eligible low-income homeowners to receive a free energy audit and upgrades to make the home more energy efficient to help save on their energy costs.

In order to be eligible for the Illinois Weatherization Assistance Program, you must own and live in your house. The house cannot have been weatherized in the past 15 years, and must meet safety requirements set for our staff.

Weatherization Waitlist

Our weatherization program works with a priority based waitlist. Many households spend over two years on this list, but it is a requited step in applying. To join the waitlist for weatherization, please call our office at (844) 710-6919.
