Duct run crushed by hanger/other trade
A crushed duct section is an airflow restriction, not just a cosmetic dent. Stop and verify repair/replacement before startup or cover.
Watch out
- Do not cover crushed duct because air “can still get through.”
Check
- Find what crushed the duct: hanger, pipe, cable tray, storage, lift, or other trade.
- Check whether the duct shape or opening area is reduced.
- Photo the damage with location/grid and reference.
- Check if seams, liner, insulation, or supports were affected.
- Ask whether to repair, replace, or escalate before covering.
