Three-Day Workshop

Refrigeration Systems Servicing and EPA Section 608 Certification Workshop

This workshop is designed specifically for maintenance technicians who are responsible for the preventative maintenance, servicing, and repair of refrigeration systems used in air conditioning equipment, commercial refrigeration systems such as walk-in and reach-in equipment, and appliances.

Fundamental principles technicians need to understand about refrigeration systems are covered along with the latest available information on refrigerant updates, and study and preparation for either the EPA Section 608 Universal Technician Refrigerant Handling Certification exam or R410A certification exam.

In addition to a take-home workbook that is used during the workshop and can later be used as a reference on the job, participants will also take their EPA refrigerant handling study manual with them at the conclusion of the workshop.
