Returned to an AC water leak report at an Oakdale California hair salon. On previous visit, our commercial HVAC tech had found a collapsed run of ducting that needed to be replaced. Upon arrival the tech removed the old duct strap and collapsed ducting. Power down unit and ran new section of duct-work and new strapping. Restarted unit and tested function and airflow. New duct run is maintaining structure, no more issues to report. Job complete.
