    Module 1: Refrigerant Usage Certification Description:

    In 1993, RSES was approved by the EPA to conduct technician certification testing as per EPA regulations. A candidate must pass each of the four question groups (Core, Type I, Type II, Type III) pertaining to the Type of certification needed. This module covers the Core group. The Core group must be taken, and a passing score received, to obtain any of the Types of certification.
