Frequently Asked Questions
Is sheet metal work the same as HVAC?
There is significant overlap. SMWIA sheet metal workers install HVAC ductwork, which is a major part of HVAC systems. However, sheet metal workers typically do not install the HVAC equipment itself (furnaces, air handlers, condensers) or work on refrigerant systems. HVAC technicians and sheet metal workers often work alongside each other on commercial HVAC projects.
How long does it take to become a journeyman sheet metal worker?
SMWIA apprenticeships are structured 5-year programs. After completing the apprenticeship, you receive journeyman certification. The total time from starting your apprenticeship to full journeyman status is 5 years.
How do I join SMWIA?
Apply to your local SMWIA chapter. Each local has its own application process and schedule. Most require a high school diploma or GED, passing a basic aptitude test, and an interview. Application periods open periodically. Visit smwia.org to find your local chapter.
