Mold Remediation

Certified by IAQA 
Fully Insured and Bonded

Mold Remediation Services
Air Cleaning System’s mold remediation services are performed in accordance with the NYC Department of Health Bureau of Environmental & Occupational Disease Epidemiology,
levels I-V. Our mold remediation procedures conform strictly to IICRC- S520, IAQA, OSHA, EPA, NADCA guidelines for assessment and remediation of fungi in indoor environments.

Mold Remediation Procedures

Mold remediation procedures differ from case to case. The following is a sample of procedures we follow when performing a typical remediation:

1. We will install plastic sheeting as per NYC Department of Health guidelines, Level I-IV Containment.
2. We will clean the interior air with a HEPA air scrubber.
3. We will remove moisture from the air with an industrial dehumidifier.
4. We will remove (sheet rock, carpeting, etc.) in the mold contaminated area.
5. We will HEPA vacuum and wipe all surfaces with an EPA registered hospital disinfectant that inhibits mold growth.
6. We will coat the area where mold was removed with an EPA registered fungicidal protective coating.
7. We will remove all debris from the site in 6 ml bags.

HVAC Cleaning Procedures

We perform a thorough inspection and cleaning of all air handlers, including heating/ air conditioning/ ventilation units, and all connecting main and branch supply return and/or exhaust ductwork, diffusers, grilles, dampers and turning vanes. All work is performed in accordance with NADCA-ACR-2005 and OSHA standards. Source removal methods are used to remove contaminants from the air conveyance system.

1. All ceiling diffusers, wall and floor registers are cleaned and sanitized.
2. Supply and return main ducts are brushed and/or whipped with high powered, compressed, air. (175 PSI)
3. Supply and return branch ducts are brushed and/or whipped with high powered, compressed, air.
4. All bathroom exhaust ducts are brushed and/or whipped with high powered, compressed, air.
5. A high efficiency particulate collector with 99.97 efficiency at .03 microns isconnected at selected points throughout the HVAC system to remove contaminants and debris.
6. All service openings are sealed with airtight access panels screwed to ducts.
7. All 2 ½ “ holes or smaller are sealed with airtight knockout plugs.
8. Filters are checked and air washed.
9. All duct openings, ceiling diffusers and HVAC units will receive hospital germicidal disinfectant / deodorizer killing most disease causing organisms.
10. Exterior of heating and cooling coils are cleaned with chemicals and thoroughly rinsed clean.

HVAC SOURCE REMOVAL CLEANING METHOD

1. Prior to the cleaning process, supply and/or return openings are covered with plastic film to fully protect surrounding areas from possible loosened debris. Plastic film is then be removed after relevant clearance testing has been completed and before the system is restarted.
2. The supply and return networks are zoned in order to be cleaned separately.
3. A high efficiency particulate collector is connected at pre-selected points throughout the HVAC system to evacuate under negative pressure the areas to be cleaned.
4. The areas to be cleaned are then be air washed, swept with forward or reverse air, power brushed and/or whipped to remove all visible dust and debris.
5. All flex ducting where found will be cleaned and air washed with forward or reverse air sweeps only.
6. All registers, grilles and diffusers will be air washed with high powered, compressed, air.
7. All service openings cut into the HVAC system to allow access for cleaning will be sealed with re-usable, airtight, sheet metal access panels with gaskets screwed to ducts. All 2 ½" holes or smaller are sealed with airtight knockout plugs.
8. Critical barriers are installed at specific points throughout system as required to protect completed areas from recontamination.
