EPA 608 Type I Jobs in Wisconsin

EPA 608 Type I certification covers refrigerant handling on small appliances — defined by the EPA as equipment with five or fewer pounds of refrigerant in a hermetically sealed system. In Wisconsin, employers requiring Type I specifically tend to work in light commercial service (window AC units, PTAC systems, residential refrigerators, and small reach-in coolers). Type I alone is generally not sufficient for full HVAC service roles; most employers either require Type II or Universal alongside it.

Type I is often the first EPA 608 section candidates pass because the equipment category is familiar and the refrigerant quantities involved are small. In Wisconsin, candidates who pass Type I while working toward Universal commonly land helper or assistant roles while completing the remaining sections. Employers who want to hire quickly sometimes bring on technicians with Type I and a clear path to Universal, especially when residential workload is pressing.
