What is a common remedy for duct leakage that is not a visual-only fix?

Addressing duct leakage means actually sealing the joints and seams, not just looking at them. Leaks let conditioned air escape, wasting energy and creating comfort problems. The common remedy is to apply a durable sealant to the joints and seams—mastic works well for many duct types—and then secure the joints with HVAC-rated tapes. This combination stops air from leaking out and improves system efficiency, comfort, and often reduces energy bills. After sealing, a duct leakage test or similar diagnostic helps verify the improvement and guide any further sealing. Simply ignoring leaks or trying to compensate by increasing fan speed doesn’t fix the underlying problem and can waste even more energy. Replacing ductwork without sealing is usually unnecessary unless the ducts are severely damaged.
