This Is What Happens During Duct Testing


If you think that something is wrong with your ductwork, the first step in addressing the problem is to complete duct testing. It’s a process that helps our team identify where you may have holes or other problems with your ductwork so that we can fix them.

Importance of Airtight Ducts

Your ductwork does the vital job of carrying heated and cooled air into your home. Over time, tiny holes can develop in your ductwork, or your ductwork may shift around and impact airflow. If your ductwork loses 20% of conditioned air through holes and gaps in the seals, it can cost you as much as 50% more on your energy bills. This is because your air conditioner or heater has to work harder to produce the same results. 

About Duct Testing

When we test your air ducts, we’re checking to see how much air is being lost due to holes and leaks. The first step in testing is to completely seal your air duct system so that it is airtight, which includes blocking all of the vents leading into your home. 

Then we attach a vacuum to pressurize your system of air ducts and use a tool to measure how much of the pressure is being lost. Once we have an idea of how much air pressure is escaping through holes, we can test individual sections and pinpoint each individual hole or broken seal. 

Next Steps

If your ductwork has a lot of damage, we may need to replace portions of the material. Then we can work to seal other holes. A lot of times air escapes through broken ductwork seals. Your ductwork is actually a set of interconnected pieces that are secured together by a special sealing tape. When that tape comes loose, it allows air to escape. The more air that escapes, the less that makes it into your home. We may need to replace all of some of the tape to ensure that your ductwork system is once again airtight. 

Once any repair or replacement work is complete, we can repeat the duct testing again. We do this to ensure that we caught every hole or broken seal. If there is still a problem, we can keep working to fix it while we are still at your home.

After resealing your ductwork, you want to be sure to schedule annual maintenance to stay ahead of problems in the future. We will check your ductwork as a part of preventative maintenance and address any holes or broken seals each year. Then you don’t have to worry about ductwork problems getting so bad that they affect your HVAC system efficiency and indoor air quality.
