CAZ Testing.

Combustion Appliance Zone (CAZ) testing is utilized to determine if efficiency improvements to a home such as insulation upgrades, or air sealing efforts, will cause unhealthy or hazardous conditions in a home.

The importance of CAZ testing.

By using pressure testing equipment, and gas and carbon monoxide analyzers, our certified energy raters and auditors can ensure that conventional gas appliances are not leaking abnormal rates of carbon monoxide or other combustion gases within a home. Following efficiency improvements including insulation upgrades, air sealing efforts, or changes to ventilation in a home, it is extremely important to have CAZ testing performed to ensure adequate draft of combustion appliances. Testing is the only way of determining safe operation of combustion appliances and safe indoor air quality for you and your family.
