Combustion Appliance Zone Testing
The Combustion Appliance Zone (CAZ) refers to your home’s mechanical room. The zone includes certain furnaces, hot water heaters and boilers. It is important to do CAZ testing after air sealing and home insulation home improvements are completed.
Green Home Consulting verifies that there is both proper ventilation and that open combustion appliances operate safely. CAZ testing is the only way to ensure that the air quality in your home is safe for you and your family.
Certified to perform CAZ testing
We use pressure-testing devices, gas detectors and CO testing equipment to verify your home meets testing standards.
Green Home Consulting is certified by the Building Performance Institute (BPI) to perform CAZ testing. It ensures that open combustion appliances are not leaking carbon monoxide and other combustible gases in the home.
