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 witth 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 have 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 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.

    Customer service was absolutely outstanding! The entire crew of Chad, Marc, Fredrick, and Dedrick were the best! They all displayed a high level of professionalism and were very knowledgeable. I had a lot of questions as to what the affects of the weatherization would be outside of just the "lowering of my energy costs." The entire team went into great detail of how the HVAC system works and how this process would impact it. They also gave me some great tips as to how to maximize my energy savings going forward when using my units. You can tell that these guys take pride in their work. They were punctual, timely, and most of all very neat. Upon their completion there is no sign s of them being here, as everything is how it was when they arrived. They were also very respectful to all of the items that were present in my home. Some things had to be moved for access and they all treated my items as if it was their own. You just don't come across this level of great customer service often anymore. I would highly recommend not only this service but this crew in particular to anyone. I am referring 4 other family members for this service and I'll be sure to specifically request this crew! Great job guys and keep up the great work!

    I had such a great experience with Jack, Shamone, and Chad! They were extremely friendly and very professional! Jack explained what would take place the morning of my appointment and answered all of my questions! They were all very understanding of my very noisy three year old as well! Thank you again you guys for such a pleasurable experience!
