Signed into law on February 17, 2009 by President Obama, this bill contains an "existing homes energy efficiency tax credit." This program is run by the Department of Energy, who is responsible for providing the funding and technical guidance to the states. However, each state runs their own programs and sets the rules for issues such as eligibility. The individual states select the contractors and review the work for quality control.

Weatherization includes the following:

1. Insulation
2. Air sealing
3. Window replacement
4. HVAC replacement
5. Water heater replacement
6. Etc.
