Sheet Metal Workers






Chartered January 1, 1988, the Sheet Metal Workers Local 66 currently has over 4,800 members.  Local 66 has a jurisdiction that covers all counties in the State of Washington with the exception of Clark and Skamania, the counties of Morrow, Umatilla, Union and Wallawa in the State of Oregon and the counties of Benewah, Bonner, Boundary, Clearwater, Kootenai, Latah, Lewis, Nez Perce and Shoshone in the State of Idaho.



Sheet metal workers make, install, and maintain heating, ventilation, and air-conditioning duct systems in both residential and commercial applications; roofs; siding; rain gutters; downspouts; skylights; restaurant equipment; industrial systems and many other products made from sheet metal. They also may work with fiberglass and plastic materials. Although most workers specialize in fabrication, installation or maintenance, some do all three jobs.

In addition to installation, some sheet metal workers specialize in testing, balancing, adjusting, and servicing existing air-conditioning and ventilation systems to make sure they are functioning properly and to improve their energy efficiency. Properly installed duct systems are a key component to heating, ventilation, and air-conditioning (HVAC) systems, which causes duct installers to sometimes be referred to as HVAC technicians. A growing activity for sheet metal workers is building commissioning, which is a complete mechanical inspection of a building’s HVAC, water, and lighting systems.

Apprenticeship Process

Apprenticeship opportunities are available in three different state approved programs within the sheet metal industry: Sheet Metal Worker, HVAC Service Technician and Sheet Metal Test, Adjust and Balance Technicians.  All three programs are five years in length and consist of both classroom and on-the-job training.


In addition to the three commercial programs mentioned above, a three year residential sheet metal apprenticeship is also available.
