HVAC system cleaning specifications
NOTE:
An engineering specification for HVAC system cleaning and sanitizing is available
from IAP. This specification is based on eleven years of actual field experience.
Today's HVAC
cleaning projects require a new level of sophistication due to the advent of:
- Highly specialized containment
equipment, including high volume HEPA and ULPA filtered vacuum collection
systems
- Advanced
source removal technology to dislodge debris adhered to interior duct surfaces
without the need for numerous access openings
- Remote
video inspection tools to pinpoint areas of concern and verify cleaning
- EPA
registered materials for specific application in HVAC systems
- Increased
recognition concerning microbial contamination, proper containment and remediation
strategies and tactics
- More
stringent standards and procedures for verification
The following should be "key" aspects of any HVAC system cleaning
specification: - Containment
of the potential contaminants.
- Effective
collection and agitation equipment.
- Adherence
to OSHA safety regulations.
- The
experience and skill level of the contractor.
- Verification
and documentation to ensure a successful project.

Importance of contractor
credentials The
complex nature of ventilation system cleaning, coupled with a better understanding
of the types of contaminants being removed from ventilation systems, makes the
need for contractor competency testing and experience all the more imperative.
Potentially harmful mold and bacteria are commonly found growing on excessive
accumulations of dust, requiring the use of chemical biocides and microbial testing.
Gone are the days of simply vacuuming-out whatever happens to be found within
the system. - The
contractor for commercial buildings should employ at least two Air Systems Cleaning
Specialist (ASCS) certified by the National Air Duct Cleaning Association (NADCA).
Depending on the complexity of the project, the on-site supervisor for the project
should be ASCS Certified.
- The
contracting organization should have at least five years of experience or be able
to reference five or six similar projects.
Mold
Remediation Guidelines
Specifications for mold remediation projects should be developed by an environmental
company that specializes in this field. For EPA information and guidelines click
