Why You Need Duct Cleaning, Part 6.

Why should I choose a NADCA member to have my air ducts cleaned?

NADCA members have signed a Code of Ethics stating they will do everything possible to protect the consumer, and follow NADCA Standards for cleaning to the best of their ability. Air duct cleaning companies must meet stringent requirements to become a NADCA Member. Among those requirements, all NADCA Members must have certified Air System Cleaning Specialist (ASCS) on staff, who have taken and passed the NADCA Certification Examination. Passing the exam demonstrates extensive knowledge in HVAC design and cleaning methodologies. ASCSs are also required to further their industry education by attending seminars in order to maintain their NADCA certification status.

What are sanitizers, and why would they need to be used?

Sanitizers are anti-microbial chemicals applied to the interior surface of the air ducts, designed to control microbial contamination. Before any sanitizers are used, the system should be thouroughly cleaned. It is critical that any anti-microbial treatment used in your system be EPA registered for the intended use in HVAC systems. Ask to see the chemical's Material Safety Data Sheet (MSDS). If you are still concerned, call the EPA, at 1-800-438-4318.

It should be noted there are no EPA registered anti-microbial products for use on pourous surfaces-such as fiberglass surfaces.
