Oregon's market runs on dairy, prepared foods, and seafood processing plus grocery distribution, so a large share of openings are plant ammonia and cold storage roles around Portland, Salem, and the Willamette Valley rather than storefront service. EPA 608 is federal and required for any refrigerant work, and the ammonia-cooled dairy and food plants often want RETA credentials on top. Pay moves with experience, overtime, certification, and employer type — see the salary-by-state ranking.
