EPA 608 Type III Jobs in Milwaukee, WI

EPA 608 Type III certification covers low-pressure refrigerant systems — primarily centrifugal and absorption chillers that use R-123 or similar low-pressure refrigerants in large commercial and institutional buildings. Employers requiring Type III in Milwaukee, WI are typically in the commercial mechanical contracting space, servicing hospitals, universities, data centers, and high-rise office buildings. The equipment is less common than high-pressure systems but the technical complexity commands higher pay rates.

Chiller technicians in Wisconsin with Type III certification typically command rates well above the HVAC median, driven by equipment complexity and the smaller pool of credentialed candidates. Manufacturer-specific training — Carrier, Trane, York, or Daikin centrifugal lines — is frequently required alongside Type III and is generally paid for by employers or through service agreements. Positions in this category often include on-call responsibilities given the operational criticality of the equipment.
