Technology: Using negative air machines with rotating brushes or air whips. Implementation: The brushes scrape dust from duct walls, while the vacuum machine draws contaminants directly into sealed bags, preventing their spread within the building.
Technique: Fogging using safe, non-toxic disinfectants. Implementation: Use hydrogen peroxide-based disinfectants or environmentally approved materials to eliminate bacteria and mold adhering to the ductwork.
Cause: Mold, moisture, and organic matter buildup on ducts and cooling coils. Solution: Sterilization eliminates the source of odors rather than just masking them, leaving the air clean and fresh.
Open appropriate access points to access the entire ductwork. Clean the cooling coils and indoor units to eliminate bacteria and moisture. Reseal access points and securely fasten inlets and outlets before operating the system.
