Core Responsibilities

Primary Functions

Perform comprehensive diagnostics, service, and preventative maintenance on a wide array of commercial and industrial refrigeration equipment, including but not limited to walk-in coolers/freezers, reach-in units, ice machines, chillers, and parallel rack systems.
Expertly troubleshoot and repair complex mechanical and electrical system failures, utilizing wiring diagrams, schematics, and technical manuals to identify root causes.
Install, commission, and start-up new refrigeration systems, ensuring proper component installation, calibration, and operational performance according to manufacturer specifications and local codes.
Execute precise brazing and soldering of copper piping to repair leaks or install new components, followed by rigorous pressure and vacuum testing to guarantee system integrity.
Handle refrigerants in strict compliance with EPA Section 608 regulations, including proper recovery, evacuation, recycling, and charging of systems, while maintaining meticulous logs of refrigerant usage.
Diagnose and repair compressors of all types (reciprocating, screw, scroll), including performing oil changes, component replacements, and full compressor change-outs.
Calibrate and adjust system controls, including thermostats, pressure controls, timers, and defrost cycles, to optimize equipment efficiency and temperature stability.
Respond to emergency service calls in a timely and professional manner, often outside of normal business hours, to mitigate product loss and equipment downtime for clients.
Conduct detailed inspections of refrigeration systems to identify potential issues, such as worn components, refrigerant leaks, or inefficient operation, and provide proactive recommendations for repair or replacement.
Perform advanced troubleshooting on supermarket refrigeration systems, including parallel racks, remote condensers, and energy management systems (EMS).
Replace and configure electronic control boards, expansion valves (TXV/EEV), and other sophisticated control components to restore system functionality.
lineman
Interpret and work from blueprints, P&IDs (Piping and Instrumentation Diagrams), and engineering specifications for complex installations and retrofits.
Conduct regular water treatment and maintenance on ice machines and water-cooled systems to prevent scale buildup and ensure sanitary operation.
Systematically evaluate system performance by measuring superheat, subcooling, temperatures, and pressures, making necessary adjustments to achieve peak operational efficiency.
Safely work with and troubleshoot three-phase and single-phase electrical circuits, motors, contactors, relays, and other electrical components related to HVAC/R systems.
Perform case cleaning, inspections, and component replacements on refrigerated display cases in retail environments.
Conduct vibration analysis and oil analysis on large-scale industrial refrigeration equipment to predict and prevent catastrophic failures.
Program and configure digital controllers and EMS dashboards to meet client specifications for temperature and energy savings.
Troubleshoot and repair issues within CO2 and glycol secondary-loop systems, ensuring proper fluid levels and flow rates.
Execute major component replacements, including condensers, evaporators, and entire rack systems, as part of system upgrades or end-of-life change-outs.

Secondary Functions

Maintain a clean, organized, and well-stocked service vehicle with an accurate inventory of parts, tools, and safety equipment to ensure readiness for all service calls.
Complete detailed, accurate, and timely digital or paper service reports for every job, documenting diagnostics, work performed, parts used, time on-site, and recommendations.
Communicate professionally and effectively with customers, site managers, and dispatchers, explaining technical problems, repair options, and estimated costs in a clear and understandable manner.
Proactively identify and quote opportunities for system upgrades, retrofits, or preventative maintenance contracts to enhance client system reliability and efficiency.
Adhere to all company, OSHA, and client-specific safety protocols, including the consistent use of Personal Protective Equipment (PPE), lockout/tagout procedures, and safe driving habits.
Provide on-the-job guidance and mentorship to apprentices or junior technicians, fostering a culture of learning, safety, and high-quality workmanship.
