CAZ Testing

Combustion Appliance Zone Testing

CAZ 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.

Safety Verification

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.

Post-testing assures you that your home energy improvements have made a difference
CAZ testing equipment. CAZ is an abbreviation for Combustion Appliance Zone.
Part of CAZ testing is to detect carbon monoxide after home energy improvements are made. It is a pre-post project testing service. Your independent home energy auditor returns after repairs to see that the work has been done properly.
CAZ testing is always accompanied by inspection by a skilled home energy auditor.

Thank you for a great job on our home energy audit. Green Home Consulting walked me around the house and attic, explaining the issues and how to fix them. I received a detailed, well-written report with prioritized recommendations. They took care of the paperwork for the rebate. I couldn't have asked for a better audit experience. Thank you!  Karan Singh Sahni, Homeowner, Aurora, Colorado
