  • Diagnose and repair sealed-system leaks, perform brazing and soldering on copper tubing, and replace valves, driers, and filter components to prevent future refrigerant loss and contamination.
  • Conduct preventative maintenance inspections and service plans for walk-in coolers, display cases, reach-in refrigerators, ice machines, and under-counter units, following manufacturer checklists to maximize equipment uptime and reliability.
  • Install new refrigeration and ice making equipment (commercial and residential), ensuring accurate piping, electrical hookups, insulation, leveling, and commissioning tests to meet manufacturer specifications and local codes.
  • Perform routine and emergency on-call service for critical failures, responding promptly to minimize food loss or business disruption for client operations in retail, restaurant, and institutional settings.
  • Calibrate sensors and thermostats, validate defrost cycles and control logic, and tune system setpoints for improved performance and energy consumption based on site-specific loading and usage patterns.
  • Maintain and document accurate service records, work orders, parts used, hours worked, and recommendations for capital upgrades or next-step repairs in the company’s field service management system.
  • Provide clear, professional explanations to customers about findings, repair options, cost estimates, warranty coverage, and preventive maintenance recommendations to support informed decision-making.
  • Source, order, and install OEM and aftermarket replacement parts, verify parts compatibility, and maintain a well-organized service vehicle inventory to reduce repeat visits and expedite repairs.
  • Test and evaluate compressor performance, pressures, superheat/subcooling, and refrigerant charge to ensure systems meet operational specifications and manufacturer tolerances.
  • Inspect electrical wiring and components for hazards, perform necessary repairs or coordinate electrical trade assistance when beyond the technician’s scope, and adhere to NEC, OSHA, and company electrical safety practices.
  • Advise customers on energy-efficient upgrades, retrofit opportunities (e.g., low-GWP refrigerants, variable speed compressors), and system modernization strategies that align with sustainability and cost-saving goals.
  • Participate in equipment decommissioning and disposal projects, following environmental regulations for refrigerant recovery, recycling, and responsible disposal of components and oils.
  • Provide mentorship and on-the-job training to junior technicians and apprentices, demonstrating safe brazing, leak detection, documentation practices, and efficient troubleshooting workflows.
  • Collaborate with account managers and kitchen/operations staff during large-scale installations or shutdowns to coordinate schedules, system staging, and phased commissioning to minimize downtime.
  • Conduct site risk assessments, maintain PPE usage, and follow lockout/tagout, confined space, and fall protection procedures when servicing rooftop condensers, walk-in units, or other elevated equipment.
  • Evaluate warranty claims, diagnose recurring failures, prepare technical reports with photographic evidence, and recommend corrective action to manufacturers or warranty administrators.
  • Utilize mobile service management apps to capture signatures, attach photos, log labor and parts, and produce professional PDF invoices and maintenance agreements on-site.
  • Support inventory control initiatives by returning unused parts, tagging serviceable components, and recommending stocking levels to the parts team based on recurring service data.

Secondary Functions

  • Assist in cross-functional initiatives such as seasonal maintenance campaigns, energy audit programs, and customer training workshops.
  • Support continuous improvement by providing feedback on common failure modes and recommending design or vendor changes to reduce service frequency.
  • Help maintain the fleet and tools by reporting vehicle maintenance needs, calibrating diagnostic equipment, and ensuring compliance with company vehicle safety inspections.
  • Contribute to sales support by demonstrating equipment capabilities to prospective customers and delivering technical input for proposals and quotes.
  • Participate in regular safety meetings, technical training sessions, and certification renewals to stay current with refrigerant regulations and emerging technologies.
