Refrigeration Mechanic

The Mid-Level Refrigeration Mechanic performs preventive maintenance, service, and component-level repairs for commercial and industrial refrigeration systems. This role requires independent problem-solving, safe refrigerant handling, basic electrical diagnostics, and system efficiency optimization while ensuring regulatory and safety compliance.

Key Responsibilities:

🧰 Maintenance & Service:

• Conduct preventive maintenance (PM) and corrective service on:

  • Walk-in coolers/freezers, chillers, ice machines, under-counter units, glycol systems

  • Display cases, refrigerated air dryers, rack systems (if applicable)

• Clean coils, replace filters, tighten electrical connections, and calibrate thermostats

❄️ Refrigerant Handling (EPA-Certified Tasks):

• Recover, evacuate, and recharge systems with appropriate refrigerant types

• Conduct leak detection using electronic detectors or soap solution

• Maintain refrigerant logs and comply with EPA/refrigerant recovery protocols

🔍 Diagnostics & Repairs:

• Identify faults in refrigeration cycle, defrost system, or electrical/control circuits

• Replace faulty components such as expansion valves, contactors, solenoids, relays, sensors

• Read pressure/temperature charts and analyze superheat/subcooling conditions

🏗️ Installation & Retrofits:

• Assist or independently install condensing units, evaporators, and control panels

• Route piping, braze joints, insulate lines, and test system integrity

• Support retrofitting systems from older refrigerants to eco-friendly options

⚠️ Compliance & Safety:

• Adhere to local HVAC codes, EPA rules, and site-specific safety requirements

• Use PPE, LOTO, confined space, and work-at-height protocols

• Identify and report safety hazards or environmental risks promptly

📋 Documentation & Coordination:

• Complete service logs, refrigerant records, and inspection reports

• Coordinate with clients, facility staff, or engineering teams on repairs and downtime

• Suggest preventive improvements to reduce breakdown frequency or energy consumption

Key Focus Areas:

• ✅ Independent Fault Identification & Component Replacement

• ✅ EPA-Compliant Refrigerant Management

• ✅ Mid-Level Electrical & Control Diagnostics

• ✅ Basic Installations, Retrofits & Brazing

• ✅ Client Communication & Team Coordination

Skills & Competencies:

• Sound knowledge of refrigeration cycles, system pressures, and compressor operations

• Ability to read schematics, wiring diagrams, and pressure-temperature charts

• Familiarity with mechanical and electrical tools, gauges, and diagnostic equipment

• Basic knowledge of defrost systems (electric, hot gas) and control systems (digital or mechanical)

• Ability to explain system issues and recommended fixes to clients or supervisors
