Be sure to contact your utility company before beginning a project to see what incentives are available in your area. You can also check for incentives using the DSIRE database for state incentives.

You may be eligible for financial assistance to make improvements like air sealing and insulating through your state's Weatherization Assistance Program (WAP).
