Getting a duct leakage test is beneficial for several reasons, and it can be a wise investment for home or building owners. Here are the key reasons why you should consider getting a duct leakage test. Duct leaks can cause significant energy wastage. When conditioned air (heated or cooled) escapes from the ducts before reaching its intended destination, your HVAC system has to work harder and longer to maintain the desired indoor temperature. A duct leakage test helps identify these leaks, enabling you to seal them and improve energy efficiency. By reducing energy wastage, you can lower your utility bills and save money in the long run. Leaky duct can lead to inconsistent airflow and temperature imbalances throughout the building. Leaky ducts can act as entry point for dust, dirt, allergens, and other pollutants from attics, crawlspaces, or wall cavities. In some regions, duct leakage testing is required by building Code and standards compliance.
