CAZ Testing

Combustion appliance zone testing by our BPI certified technicians

CAZ Testing

CAZ testing is a series of proven checks to systematically assess combustion appliance safety

If your home contains natural-draft appliances [such as a natural-draft furnace, or water heater] located within the conditioned space of your home, then combustion safety testing must be conducted to ensure safety and indoor air quality. Diversified Energy’s BPI certified technicians are trained to properly conduct advanced CAZ testing. We not only provide you with the results of your CAZ, but actionable options for how to correct any problems.

Don’t put the health and safety of your family at risk, contact us today to schedule your CAZ test.

What Is A CAZ Test?

Open combustion heating equipment located within the conditioned space of your home has the potential to allow Carbon Monoxide and other poisonous combustion by-products to enter your indoor environment. A CAZ [Combustion Appliance Zone] test is a proven and conclusive method of determining whether this could happen under certain “worst case” or natural conditions. A CAZ test should always be performed if air sealing is performed on your home and you have open combustion appliances located within the conditioned space.

These Combustion Appliance Zone (CAZ) tests are designed to ensure that flammable fuels or combustion gases are not intruding into the home’s living spaces. CAZ testing also assures homeowners that their appliances are functioning in a safe and efficient manner. This series of tests is mandatory for your family’s safety and is required by most utility companies for any home with combustion appliances located in conditioned interior living spaces. The series of CAZ tests covers these five categories: gas leak testing, depressurization testing, carbon monoxide testing, spillage testing, and draft testing. 

Our BPI certified technicians are trained to properly perform CAZ testing and understand the unique challenges we face in our Gulf South climate. CAZ testing can be included in our 360 Energy Audit and/or conducted in combination with any of our advanced diagnostic testing services. Contact us today to schedule your CAZ test.

What If My Home Fails A CAZ Test?

If your home/combustion appliance zone fails our CAZ tests, then we will recommend the corrective measures you will need to take to remedy the problems. The corrective measures can include: Adding direct venting of the combustion appliance zone. Air sealing to separate the appliance combustion zone from the rest of the conditioned space in your house. Or, in the case of very old equipment, replacement of the equipment.

    My electricity bill was outragous so I called Diversified Energy for home energy assessment. They came out to test, found the issue and resolved it immediately. Highly recommend!

    Chad came to preform a home energy audit for us through Cleco and we were beyond impressed! He was super polite and professional and explained everything to me and gave lots of helpful tips for conserving energy. He also sealed several places, changed out lightbulbs to led and shared the testing results with me. Highly recommend!

    Great job!!! Chad was excellent. He was very professional and thorough. He discovered a hole in our duck work that he fixed which should save us money.
