Leaking or disconnected ductwork

Canonical HVACentric knowledge for all questions on this topic.

DIRECT ANSWER

Duct leakage can lose conditioned air, pull unwanted air into the system, and contribute to comfort, pressure, dust, and energy problems. A useful assessment inspects accessible ducts and may measure leakage or pressure rather than relying only on a visual guess. Repair methods should match the duct material and address disconnected, crushed, poorly supported, or contaminated sections as well as gaps.
