Today I performed ductwork restoration services at a residence in Highland Park, Illinois. The scope of work involved applying the initial coat of Duct Armor sealant to all underground duct runs as well as the interior of the furnace box itself. Duct Armor is a specialized elastomeric coating that seals and encapsulates duct surfaces to prevent moisture intrusion, inhibit mold growth, and improve airflow efficiency. Properly sealing and insulating ductwork is an important part of maintaining healthy indoor air quality and optimizing HVAC system performance. After allowing the first application to cure, a secondary coat will be applied to complete this duct rehabilitation project.
