Weatherization Program through Community Action Agencies in Connecticut:

Connecticut Weatherization Assistance Program (WAP) assists low-income persons to minimize energy related costs and fuel usage through home improvement measures. The program provides an energy audit to help determine the weatherization measures that need to be installed to make the dwelling more energy efficient. Typical measures may include heating system tune-ups and repairs, blower door guided air-sealing, attic and sidewall insulation and health and safety inspections.

The Weatherization Program goes up to 60% of the State Median Income for all households. The program pays for energy conservation improvements.
