warning iconCombustion Safety

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.

warning icon 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.
