Use the chart below to match your biggest concerns to the home improvement projects that may be able to address them and deliver the comfort and energy efficiency you are looking for.
In some situations, sealing your home or ductwork can cause combustion appliances like water heaters to backdraft, creating unsafe conditions inside your home.
Inspection and testing by a home energy professional can help to identify combustion-related health and safety issues that should be fixed before any air sealing or other efficiency improvements are made.
Safe Indoor Air Quality
Sealing your home may trap indoor air pollutants such as radon, carbon monoxide and volatile organic compounds. A tight home may require additional mechanical ventilation to maintain safe air quality in the home.
For more information on safe ventilation, visit EPA's Indoor Air Quality for Homes pages and DOE's Guide to Home Ventilation.
