Wisconsin HVAC technician license requirements
The answer
Wisconsin regulates HVAC at the business level: every business installing or servicing HVAC equipment must register as an HVAC CONTRACTOR (SPS 305.70), and the HVAC QUALIFIER certification (4 years × 1,000 hours experience — or 4 years of education, or a combination — plus an exam) exempts the business from local licensing statewide. Technicians as employees are not individually licensed; EPA 608 applies federally.Your paths to the license
HVAC Qualifier certification
Document at least 1,000 hours per year for 4 years supervising or performing HVAC design/installation/servicing (Form 3122T, employer-signed) — or 4 years in a mechanical-engineering or accredited HVAC program, or any 4-year combination — then pass the exam.
Register the business as HVAC Contractor
Any business installing or servicing heating, ventilating or air-conditioning equipment must hold the DSPS HVAC Contractor registration (SPS 305.70). Employing a certified HVAC Qualifier makes it a certified HVAC business exempt from local licensing.
Start as a technician
Work for a registered HVAC contractor — no individual state license needed. Get EPA 608 certified for refrigerant work and log your hours toward the Qualifier certification.
