The purpose of the Weatherization Program is to significantly reduce heating costs and conserve energy nationwide.

Weatherization is provided free to qualified McHenry County residents through a grant from the Illinois Office of Energy Assistance.

Clients who participate in the Low Income Home Energy Assistance Program (LIHEAP) automatically qualify for Weatherization. Client's who are over income for LIHEAP may qualify for DOE Weatherization which has higher income limits.

Renters may be assisted under this program provided they meet income guidelines, and their landlord agrees to pay the portion of the furnace cost only.

A certified auditor conducts an assessment of the home. The information collected is analyzed by computer to determine what materials are most cost effective. Contractors install the materials. In addition, an experienced heating contractor examines the heating system to assure the system is safe and in good working order. Once the work is completed, the materials installed and the furnace work complete, all are inspected by certified personnel to make sure all work was done completely and correctly.

Weatherization includes:

  • Sealing cracks
  • Adding insulation
  • Repairing windows
  • Weather stripping and caulking
  • Minor home repairs and various other energy conservation measures that will make the home warmer in the winter and cooler in the summer
    tune, clean, and safety check of the furnace retrofits to increase heating system efficiency such as vent dampers, clock thermostats and electronic ignitions
  • Smoke/carbon monoxide detectors
