A ceiling is being closed before the HVAC contractor has balanced branch airflows, and several balancing dampers will be inaccessible. What should be done?

Correct Answer

C) Coordinate access and complete or preserve access for balancing before concealment

Air balancing needs access to dampers and devices; ceilings should not conceal required adjustment points without access panels or completed balancing. Other choices prevent proper commissioning.

Answer Options
A
Close the ceiling and estimate airflows later, leaving balancing dampers unverified
B
The contractor should remove all dampers so balancing is unnecessary
C
Coordinate access and complete or preserve access for balancing before concealment
D
Balance only the nearest diffuser and close the remaining ceiling

Why This Is the Correct Answer

Air balancing needs access to dampers and devices; ceilings should not conceal required adjustment points without access panels or completed balancing. Other choices prevent proper commissioning.
