Claims by Unidentified Speaker — Floor Ducts Gone Wild! #HVAC wood registers may block airfl… [Ayt7tGCEsOg] (4)

Closed dampers in floor registers create approximately half an inch of water column static pressure accumulation on the supply side of HVAC systems, indicating significant airflow restriction and system imbalance.

factualHVAC/building systems

Floor registers made with wooden grills allow damper arms to be kicked completely shut during normal foot traffic, creating a widespread installation problem where dampers end up in the closed position without owner awareness.

factualHVAC/building systems

A damper that was thought to be broken (not responding properly) was actually just in the closed position from accidental foot traffic, demonstrating that visual inspection of damper position is necessary during HVAC diagnostics.

factualHVAC/building systems

Damper arms on floor registers lack mechanical design features to prevent accidental closure from foot traffic, requiring manual repositioning during service calls to ensure they remain open.
