The Refrigerant Handling Supervisor (Mid-Level) is responsible for leading daily operations related to the charging, recovery, and diagnostics of automotive refrigerant systems using R-1234yf and CO₂ (R-744). This role manages lab and vehicle-based activities, ensuring safe practices, regulatory compliance, and accurate system performance. The supervisor coordinates test setup, performs root cause analysis of refrigerant-related issues, and trains junior technicians on equipment usage and safety protocols.
Key Responsibilities:
Supervise and execute refrigerant charging, recovery, and service tasks on HVAC systems using R-1234yf and CO₂ refrigerants.
Operate and maintain refrigerant service tools such as vacuum pumps, electronic leak detectors, recovery units, and pressure-temperature monitoring systems.
Monitor and validate refrigerant system pressures, charge weights, and cycle performance under varying test conditions.
Lead troubleshooting of A/C and heat pump circuits, including identification of refrigerant leaks, blockages, or component faults.
Train and mentor junior technicians in safe refrigerant handling procedures, emergency response, and EPA compliance.
Maintain detailed service logs, refrigerant inventory records, and documentation aligned with SAE, EPA, and OEM standards.
Support development and validation testing for HVAC systems, contributing to prototype builds, durability testing, and emissions-related evaluations.
Ensure lab safety practices are enforced during high-pressure CO₂ operations and refrigerant exposure risks.
Key Focus Areas:
Supervision of refrigerant handling operations for automotive HVAC systems
Hands-on work with R-1234yf and CO₂ refrigerant circuits
Troubleshooting of thermal systems and refrigeration cycle faults
Regulatory compliance with SAE J standards and EPA 609 protocols
