01 · ABOUT THIS PROJECT

We completed a comprehensive air duct cleaning, fiberglass insulation repair, and duct access door installation to restore HVAC system efficiency and indoor air quality. To stop airborne particles from circulating through the airstream, we removed deteriorated fiberglass liner from inside the ductwork. We thoroughly cleaned the air ducts and vent grilles, clearing out accumulated dust and debris. The exterior fiberglass insulation wrapping was repaired and replaced to prevent condensation and protect thermal performance. Finally, we installed five secure metal access doors across the duct run to simplify future HVAC maintenance and inspections.
