Check closed dampers before escalating an airflow complaint. Know which dampers you are allowed to adjust.

Field checklist

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

Do not reset or adjust unknown dampers just to make air show up.

Some dampers are simple balance dampers. Others are life-safety or controls devices with reset/inspection rules.
