Repair or Replace AC Ductwork: Questions for the Inspection

A dirty duct, a disconnected joint and a physically damaged section call for different work. Start with a survey that identifies the affected route and what can be seen. A photograph of one opening cannot establish the condition of every concealed branch.

Use the finding to define the next scope

Recorded finding

Scope to discuss

What stays unproven

Accessible contamination without visible damage

Cleaning method and limits for that material.

Hidden sections that were not inspected.

Open joint or kinked flexible connection

Local repair, support and an applicable operating check.

Whether other branches have the same fault.

Damaged duct or plenum material

Extent of removal, replacement route and finish/access impact.

Full condition beyond the opened area.

At Icon Bay, the inspection recorded duct and plenum defects, mould and damaged pipe insulation; the subsequent plan included duct, insulation and other replacements (16266, 16277). A plan is not a completion record. At Bluewaters, the team found a kinked flexible connection at a grille (17413), a more local observation that should not be inflated into whole-system replacement.

Before approving the work

Ask for a marked route drawing or photos tied to locations, the area to open, material and access assumptions, protection of occupied rooms, and how joints and airflow will be checked after work. Obtain a separate change procedure for defects discovered behind closed ceilings. Ask which parts of the original ductwork will remain uninspected. This makes cleaning and replacement estimates comparable without claiming that one is always the right remedy.
