Receive the call that the humidifier had broken and fell off the furnace and that there was a big hole now in the duct. Arrived on site and removed the broken humidifier, put a piece of patch metal over the plenum and sealed it with duct tape. I could not disconnect the water solenoid valve as the saddle valve at the humidifier will not shut off and it will leak water otherwise. We will put together a price to install a new humidifier and water line, if they decide not to replace the humidifier then we should return to eliminate the saddle valve to prevent a future water leak.
