System Recovery and Evacuation

Course Description (about the program)

When installing or servicing an air conditioning or refrigeration system, two of the most important tasks performed by technicians are refrigerant recovery and system evacuation. In order to perform these tasks properly, and in a safe manner, technicians need to understand the theory behind them, having a working knowledge of the equipment and tools used, and employ accepted industry best practices. This program walks through each step of both tasks, while covering safety, theory, and application.


HVACR and plumbing educational programs located in high school, community college, trade school or apprenticeship program will find this program can be integrated into your program or be used as a stand-alone course.

HVACR wholesalers, manufacturers and continuing education providers will find this program is excellent to reinforce concepts in a 6-8-hour training program.
