Abstract
An inspection system for an HVAC device includes an HVAC duct section, a damper positioned with the duct section, an actuator for selectively moving the damper to a closed position, and a verification camera for recording the position of the damper with a date stamp and a time stamp. The actuator is further configured to move the damper to its open position, and the verification camera is further configured to record the open position of the damper with a second date and time stamp.
