Applied a second coat of Duct Armor to all registers, duct runs, and the plenum. This application ensures a more durable and long-lasting seal, enhancing the structural integrity and efficiency of the ductwork. The coating also helps prevent future corrosion and leaks, providing better indoor air quality and improved HVAC system performance. After the application, we conducted a thorough inspection to ensure complete and even coverage, confirming that all areas were adequately treated and protected.
