Mold Remediation for Air Duct and HVAC Systems
Mold Remediation for HVAC systems should only be done by experienced contractors. If any part of the system is neglected, any mold growth that might remain in the area could potentially re-contaminate the entire system.
DUCTZ is the number one subcontracted company by Restoration and Remediation companies. When a remediation company is employed by an insurance company to perform mold remediation on a property, the remediation company will only get paid if they can pass a clearance test at the end of the remediation. Clearance tests assure that mold count in the property is in within acceptable lelvels.
Remediation companies prefer working with DUCTZ because they know they can trust DUCTZ to clean and remediate the system in the proper way.
Equipment used while remediating biological growth is as important as the procedures that need to be followed. All equipment must be HEPA (High-efficiency particulate air) filtered. This means the air filtered must remove 99.97% of all particles greater than 0.3 micrometer, which is much smaller than average mold spore. This assures any mold spores disturbed during the remediation will be captured in the equipment and will not be released back to indoor air.
DUCTZ does not use any chemicals that are biocides inside the duct system. We do not spray any chemicals and attempt to kill mold or any other biological growth. Proper remediation techniques is to remove the contamination from the system (source removal.) Then, depending on the type of duct work, a preventative product with anti-microbial could be used as an option to prevent future biological growth.
For duct board and air handler insulation we use a surface sealant such as Fiberlock 8000 or similar that seals the fibers in, covers the surface and makes it smooth and non-porous. It also contains an EPA-registered active ingredient to deter future fungal activity on or in the coating.
For nonporous surfaces like flex duct, metal duct work and on the air handler components, DUCTZ uses BBJ C1 antimicrobial. The product is applied through fogging on the duct work and air handler components. The product “controls and inhibits the growth of microorganisms- such as gram positive and gram negative bacteria, and mold- that forms on the air ducts, cooling coils and other working parts of the system.”
