Leaky ductwork is fairly commonplace, but pinpointing the exact location of leaks is challenging. This is where duct testing comes in. When conducted by trained and certified experts, duct testing can help you devise a plan to remedy faulty ductwork, which helps you regain energy efficiency and comfort for your home. Duct testing is a specific procedure, and understanding how to properly conduct duct testing and interpret the results takes training and expertise, both of which our indoor air quality experts in have.
When should you have your ducts tested? If you suspect you have leaky ductwork, it’s important to have your ducts tested as soon as possible. Another good time to test your ductwork is when you are moving into a new home that has ductwork so you can assess the health of the system. Been in your home for a while? You should test your ductwork every 3–5 years. Leaky ductwork can create a host of issues for you and your home, but with professional duct testing by our trained experts, you can remedy these issues quickly.
The most common way to test your ducts is by using a calibrated fan that mimics the normal air pressure of your ductwork as air passes through it. The fan is connected to your duct system, and all remaining duct registers and grills are sealed off. The fan gently adds air to your ductwork until it reaches 25 Pascals (PA) of air pressure, which is the same rate at which your forced air blows. The digital gauges on the calibrated fan provide readings based on the pressure inside your air duct; these readings are converted into cubic feet per minute (cfm). If a high amount of air is needed to maintain the pressure inside the ducts, your ductwork is leaking and will need service.
Unfortunately, all homes leak. The goal is to make the amount of leakage as little as possible for your particular property. The basic standard for maximum acceptable leakage is 12%. However, if you want to go by ENERGY STAR standards, the maximum acceptable leakage rate is considerably lower, coming in at 4%. With such a wide range, it’s recommended that your home land in the 8%—10% range for total leakage, something our experts can help you assess.
Leaky ductwork can account for over 30% of your home’s total air loss. Leakage this high can compromise your indoor comfort, put excessive stress on your HVAC system to perform, and lead to increased energy bills. With professional duct testing by our trained experts, you can find any leaks in your ductwork and remedy them, restoring your ductwork and making your home environment more comfortable.
