Chill Champion: Conquer the 2026 ESCO Refrigeration Exam!

Recovery efficiency is the percentage of refrigerant removed from the system during the recovery process. This concept matters because EPA 608 rules require technicians to use certified recovery equipment that captures a high portion of the refrigerant when servicing or disposing of equipment, minimizing emissions. The higher the recovery efficiency, the more refrigerant is actually recovered and not vented to the atmosphere, which helps protect the environment and meets regulatory obligations. This is not about how fast the refrigerant is removed (that’s a flow rate issue), nor about how much refrigerant remains after recovery (the opposite of efficiency), nor about the energy performance of the compressor. The aim is to maximize capture to reduce harmful emissions and stay compliant with the rules.
