ASCS certification shows that an individual is educated on cleaning HVAC systems, OSHA regulations and standards set by NADCA. CVI certification shows that the recipient has received Environmental Protection Agency training, and VSMR certification is focused on comprehending fundamental microbiological contamination as well as project assessment and the proper application of NADCA standards.
