Closed damper not checked before complaint
Check closed dampers before escalating an airflow complaint. Know which dampers you are allowed to adjust.
Watch out
- Do not reset or adjust unknown dampers just to make air show up.
Check
- Find the damper serving the complaint area.
- Identify if it is volume, fire/smoke, motorized/control, or backdraft.
- Verify position and access.
- If it is fire/smoke or controls-related, stop and ask before touching.
- Report the damper type/position to foreman/TAB.

Say this to your foreman
The damper serving [room] appears closed/unknown. Is this a volume damper I can open, or does it need foreman/TAB/fire-damper direction?
