  1. Which NADCA standard establishes the benchmark cleanliness level for HVAC system components after cleaning?

    Answer: NADCA ACR 2013

    NADCA ACR 2013 (Assessment, Cleaning, and Restoration of HVAC Systems) sets the industry benchmark for cleanliness verification.

  2. When performing a visual inspection of ductwork post-cleaning, which lighting level is recommended by NADCA for adequate assessment?

    Answer: 50 foot-candles at the duct surface

    NADCA recommends a minimum of 50 foot-candles of illumination at the duct surface to conduct an adequate visual inspection.

  3. A client requests third-party verification of duct cleanliness. Which test method involves collecting a surface sample and analyzing it under a microscope?

    Answer: Tape lift sample

    A tape lift sample collects debris from duct surfaces and is analyzed microscopically to quantify contamination levels.

  4. Under NADCA guidelines, what is the maximum acceptable level of non-fibrous particulate on duct surfaces after cleaning?

    Answer: 0.75 mg per 100 cm²

    NADCA ACR 2013 specifies that non-fibrous particulate should not exceed 0.75 mg per 100 cm² after cleaning.

  5. Which document should an ASCS technician provide to the building owner upon project completion to demonstrate compliance?

    Answer: Project completion report with pre/post inspection findings

    A project completion report documenting pre- and post-cleaning inspection findings demonstrates that work met NADCA standards.

  6. What is the primary purpose of performing a pre-cleaning inspection before HVAC cleaning begins?

    Answer: To establish baseline contamination levels and identify system deficiencies

    A pre-cleaning inspection establishes baseline contamination conditions and identifies deficiencies that must be addressed during the project.

  7. Which regulatory agency requires HVAC cleaning contractors to maintain Safety Data Sheets (SDS) for all chemical agents used on the job site?

    Answer: OSHA

    OSHA's Hazard Communication Standard (HazCom) requires contractors to maintain SDS for all hazardous chemicals used at job sites.
