[Kris & Al]

Wife told me we had zero air coming out of the bathroom floor vent. Took a flashlight and shined down the vent and saw a vent laying beneath it. Unscrew the vent from the floor, reached in and brought the flex duct up. The hose clamp didn’t hold the flex to the vent. Reconnected it and all fixed! Surprisingly easy. Easy stuff first, hard stuff later.
