The Illinois Home Weatherization Assistance Program (IHWAP) is designed to help low income residents save fuel and money, while increasing the comfort of their homes.

IHWAP is funded by the U.S. Department of Energy (DOE), the U.S. Department of Health and Human Services (HHS), and the state supplemental Energy Assistance Fund. Weatherization services are provided by local community action agencies or not-for-profit agencies throughout the state. You may contact the agency provider in your area, to apply for weatherization services.

  • A person contacts the appropriate agency provider in your area.
  • The agency determines if the household is income eligible and notifies them within 30 days after all the required documentation has been received.
  • If the household is eligible, one of the trained agency staff will assess the home and conduct an energy audit (survey) that will determine what work can be done to save the most energy.
  • The work to be done on your home will be scheduled and the agency will contact you to arrange a time for the weatherization work to begin.
  • Experienced workers using the work order generated from a computerized audit will apply the appropriate materials to your home.
  • The home is inspected to make sure the work is complete and correct.
