NADCA Certifcations Explained
Ventilation Maintenance Technician (VMT)
The Ventilation Maintenance Technician (VMT) certification from NADCA is a job skill training program for entry-
level field technicians. The VMT Course is specifically designed to help new HVAC cleaning technicians develop
the knowledge and skills needed to provide the high quality of service for which NADCA members are known.
The Ventilation Maintenance Technician Program is consistent with NADCA standards and guidelines, ensuring
our technicians learn how to do the job right. The course emphasizes the need for reviewing company-specific
methods and practices.
Air Systems Cleaning Specialist (ASCS) certification signifies a high level of professionalism in the HVAC
cleaning industry. Through certification, we’ve demonstrated the requisite knowledge of HVAC system cleaning,
NADCA standards, OSHA regulations and more. By passing an extensive certification examination, we’ve
achieved a reputation of reliability and competence. We have the ability to assess, restore and maintain HVAC
systems, protecting health & safety of building and occupants, performing the cleaning and mold remediation.
Ventilation System Mold Remediator (VSMR) certification signifies advanced knowledge of microbial
growths, bacteria, viruses that may thrive inside HVAC systems and ductwork. Those holding the VSMR
certification know proper cleaning techniques, the dangers of molds, bacterias, etc and how to protect
themselves and your home during the cleaning process. Efffective June 2013, the VSMR coursework was
incorporated into the ASCS training and examinations, so going forward, anyone holding the Air System
Cleaning Specialist certification is also qualified as a VSMR.
Certified Ventilation Inspector (CVI) certification is earned by individuals to assess the cleanliness and
physical condition of a commercial building’s HVAC system. HVAC inspectors are trained to determine whether a
system is contaminated, or if HVAC performance is compromised. The course was designed for HVAC system
