The Inland Empire is the cold storage backbone for greater Los Angeles. Refrigerated distribution centers line I-10 and I-15 through Ontario, Riverside, and Fontana, moving produce, dairy, and beverages for all of Southern California, which makes this one of the densest concentrations of warehouse refrigeration work in the state. Expect large rack and industrial systems more than storefront service, and plan around California's C-38 license early.
Hiring extends into Riverside, Fontana, Rialto, Rancho Cucamonga, and San Bernardino, so the whole I-10/I-15 spine is in play. Across all of these, an EPA 608 certification is federally required to handle refrigerants, and the warehouse operators favor cold storage experience. California requires a C-38 contractor license for commercial and industrial refrigeration work, so check the state license requirements guide before you apply.
California's statewide average for refrigeration technicians, mechanics, and engineers runs about $74,000 a year, and the heavy cold storage work along the I-10/I-15 corridor tends to track that, with on-call and overtime adding to base. See the salary guide for how roles compare.

Warehouse and distribution refrigeration dominates, so expect large rack systems and industrial ammonia at the produce, dairy, and beverage distribution centers far more than small commercial service calls.
