IVHM Air Handler Cleaning Appendix A~3.pdf

This is a detailed technical specification document outlining requirements for HVAC system cleaning services. The document establishes comprehensive standards and qualifications for HVAC cleaning contractors, requiring them to be certified members of the National Air Duct Cleaners Association (NADCA) and recommending additional memberships in ASHRAE, ASHE, and NFPA. The scope covers cleaning of all HVAC system components including air handling units, ductwork, coils, fans, and related equipment, with specific requirements for inspection, containment, particulate collection, and verification of cleanliness.

The specifications mandate strict safety and environmental protection measures, including HEPA filtration with 99.97% collection efficiency for particles 0.3-micron size or greater when exhausting inside buildings. Contractors must document pre-existing conditions, follow NADCA standards without modification, maintain proper certifications and safety documentation, and provide detailed post-project reporting including photographic documentation. The document references multiple industry standards and publications from organizations including NADCA, UL, ASHRAE, EPA, and NAIMA that form part of the specifications.
