NADCA’s Certified Ventilation Inspector (CVI) certification was developed to recognize those industry professionals involved in the inspection of HVAC systems. CVI certified individuals are qualified to perform inspection of commercial HVAC systems. The CVI certification enhances one’s professional development and is a world‐wide credential recognizing one’s knowledge and skills related to HVAC system hygiene and inspection. In order to sit for the CVI Certification Exam, an individual must hold an active Air Systems Cleaning Specialist (ASCS) certification. NADCA worked with independent test development experts and industry Subject Matter Experts (SMEs) engaged in the practice of HVAC system inspection to perform a job task analysis for the CVI certification. The job task analysis ensures the credential reflects the most current practices in the industry and properly reflects the knowledge, skills and abilities required for inspection of commercial HVAC systems.
