• Use authorized electrical, refrigeration, leak-detection, airflow, pressure, temperature, humidity, and vibration test instruments
• Coordinate assigned technicians and contractors; communicate expectations, monitor safety and quality, resolve technical issues, and report status
• Inspect completed work for scope, manufacturer, site, and code compliance; restore safeties, panels, insulation, labels, and housekeeping before return to service
• Estimate labor, materials, equipment, and contractor needs; prepare parts lists and support critical-spares decisions
• Create clear work orders and job plans; document cause, condition, refrigerant movement, measurements, labor, materials, tests, and follow-up in the CMMS
• Identify repeat failures and recommend improvements to equipment, controls, PM, operating practices, spare parts, energy use, and training
• Mentor technicians in HVAC/R diagnostics, controls, refrigerant handling, brazing, planning, documentation, and safe work practices
