Milwaukee work splits three ways: industrial ammonia at Molson Coors and the food plants along I-94, rack and case work through Roundy's regional grocery network, and cold storage at Lineage and Americold. Wisconsin's statewide average for refrigeration techs, mechanics, and engineers runs about $65,000, which puts the metro mid-pack nationally but ahead of most of the upper Midwest. Wisconsin has no statewide refrigeration technician license, so your EPA 608 certification plus documented field time is what gets you hired.

Questions
Milwaukee Refrigeration FAQ
What do refrigeration techs make in Milwaukee?
Wisconsin's statewide average for refrigeration technicians, mechanics, and engineers is about $65,000 a year, and Milwaukee sits at or above that because of industrial ammonia and brewing work. See the state salary ranking for how Wisconsin compares.
Do I need a state license to work in Milwaukee?
Wisconsin does not license refrigeration technicians at the state level, so EPA 608 is the only federal requirement to handle refrigerants. Contractor licensing and local permitting still apply, so check the state license requirements guide.
Is ammonia experience required in this market?
Not to start, but it's the ceiling-raiser here. Molson Coors, Lineage, and Americold all run ammonia, and techs with RETA CARO or CIRO credentials command the top of the local range.
