CNADCA Certifications & Memberships

National Certification Framework

All CNADCA certifications are anchored to CNADCA Standard IAQ-100-2025, a Canadian-specific technical standard developed through a rigorous, evidence-based process aligned with national building codes, safety regulations, and modern IAQ science.

Certification through CNADCA signifies verified competence, ethical compliance, and accountability—for companies, technicians, vendors, and industry professionals.

Certified Air Systems Technician – Level 1 & Level 2

The CAST™ (Certified Air Systems Technician) designation is a controlled professional
credential issued by CNADCA™ to technicians who have successfully completed the CNADCA
Certification Program and demonstrated technical competency in accordance with CNADCA
Standard IAQ 100-2025.
‍
The CAST™ program is structured across two progressive certification levels to ensure technical
proficiency, procedural compliance, and standards-based operational accountability within the
HVAC hygiene and indoor air quality sector.

CAST™ Level 1 – Certified Air Systems Technician

CAST™ Level 1 confirms foundational technical competency in HVAC system assessment,
negative air system operation, and procedural cleaning methodology aligned with CNADCA
Standard IAQ 100-2025.
‍
Level 1 Certified Technicians have demonstrated:

• Has completed formal CNADCA-approved training

• Working knowledge of HVAC system components and contamination pathways

• Understanding of negative air collection systems and airflow principles

• Competency in procedural cleaning techniques and containment protocols

CAST™ Level 2 – Advanced Certified Air Systems
Technician

CAST™ Level 2 represents advanced technical designation and supervisory-level proficiency.
This certification confirms deeper operational understanding, compliance oversight capability,
and enhanced system verification competency.

Level 2 Certified Technicians have demonstrated:

• Advanced knowledge of CNADCA Standard IAQ 100-2025 technical requirements

• Proficiency in airflow verification, pressure differential validation, and system
  performance evaluation

• Understanding of equipment calibration, performance benchmarking, and documentation
  controls

• Competency in job-site compliance oversight and quality assurance verification

• Ability to interpret and apply standards revisions and regulatory alignment updates

Certification Governance & Oversight

All CAST™ certifications are issued under formal CNADCA governance and controlled
certification protocols.

Certification validity is contingent upon:

• Active affiliation with a compliant CNADCA-certified company

• Ongoing adherence to CNADCA technical standards and ethical requirements

• Completion of required updates resulting from revisions to CNADCA Standard IAQ 100-
  2025

• Maintenance of professional conduct and operational compliance

CNADCA retains full authority to audit, review, suspend, or revoke certification status where
necessary to preserve public trust, technical integrity, and standards enforcement.

Through CAST™ Level 1 and Level 2 certification pathways, CNADCA establishes a structured
technician hierarchy that supports industry advancement, consumer protection, and regulatory-
grade operational discipline across Canada.
