One room has too much air and the next room has too little

Treat room imbalance as a branch/damper/device investigation. Compare both branches before moving anything.

Stop if

• Room [A] is high and room [B] is low. Can I compare branches, dampers, flex, and device tags before anyone changes the unit?

Watch out

• Do not start closing random dampers to chase one room complaint.

Check

• Identify both rooms/devices and what branch/VAV serves them.
• Check damper positions and labels.
• Compare flex length, kinks, boot alignment, and device size.
• Look for wrong takeoff direction or swapped branch.
• Ask before changing damper settings or relocating taps.
