Overview
A verified baseline of
dryer vent competence.
The NDVSA Level 1 Dryer Vent Technician Certification is designed for professionals seeking foundational training in residential dryer vent inspection, cleaning, safety, and maintenance procedures.
It establishes a verified baseline of competence — the standard a homeowner, property manager, or franchise can point to and know what they're getting. Upon successful completion, technicians may represent themselves as an NDVSA Certified Level 1 Dryer Vent Technician.
Curriculum
What the program covers.

02
System Fundamentals

03
Cleaning Procedures
Proper sequencing, tooling, and verification for residential dryer vent cleaning — from access to post-service confirmation.
04
Safety Inspections & Hazards
Structured inspection workflows, hazard identification, and the documentation a technician owes both the customer and the file.
05
Airflow & Performance
Static pressure, exhaust velocity, restriction diagnosis, and the benchmarks that distinguish a working system from a marginal one.
