Responsibilities and Duties Include:

Install, assemble, test, troubleshoot, and commission refrigeration systems and associated components within custom air handling units.
Read and interpret mechanical drawings, refrigeration schematics, piping diagrams, electrical drawings, and equipment specifications.
Install and connect refrigeration components, including compressors, condensers, evaporators, expansion valves, filter-driers, pressure switches, solenoid valves, and associated controls.
Fabricate, assemble, and install refrigerant piping using approved cutting, bending, fitting, and brazing techniques.
Perform high-quality brazing of copper refrigerant piping using appropriate materials, equipment, and nitrogen purging practices.
Conduct nitrogen pressure testing, leak detection, system evacuation, and dehydration in accordance with applicable standards and manufacturer specifications.
Charge refrigeration systems with appropriate refrigerants, verify operating pressures and temperatures, and confirm proper system performance.
Diagnose and troubleshoot refrigeration system issues, including refrigerant leaks, compressor faults, airflow concerns, control malfunctions, and performance deficiencies.
Test and adjust refrigeration controls, thermostats, pressure controls, and other operating and safety devices.
Install, inspect, test, and troubleshoot gas-fired heating equipment, burners, valves, regulators, and associated controls, where appropriately certified and authorized.
Perform gas pressure testing, combustion analysis, and equipment adjustments in accordance with applicable codes and manufacturer requirements, where qualified.
Work with Engineering and Production teams to identify design concerns, resolve technical issues, and recommend improvements to equipment assembly and performance.
Support equipment start-up, functional testing, and quality inspections to ensure completed units meet customer specifications and internal quality standards.
Maintain accurate records of testing, inspections, refrigerant handling, and equipment performance as required.
Ensure all work complies with applicable refrigeration, gas, electrical, environmental, and occupational health and safety requirements.
Maintain tools, equipment, and work areas in a safe, clean, and organized condition.
Provide technical guidance and support to less experienced team members when required.
Other duties as assigned.

Proven ability to read and interpret mechanical drawings, piping diagrams, electrical schematics, and technical specifications.
Experience working with commercial HVAC equipment, custom air handling units, rooftop units, or industrial refrigeration systems preferred.
Strong mechanical aptitude with experience using refrigeration gauges, vacuum pumps, leak detectors, multimeters, and other diagnostic equipment.

Excellent troubleshooting, analytical, and problem-solving skills.
Ability to work independently while collaborating effectively with Production, Engineering, and Quality teams.
