We're looking for someone who is confident working independently, takes pride in their workmanship, and enjoys solving technical challenges in a hands-on manufacturing environment.

Why You'll Love This Role

Technical Variety & Challenge: Work on custom-built HVAC equipment, where every project brings different specifications, configurations, and technical challenges.
Autonomy & Impact: Apply your experience and technical judgment to troubleshoot problems, improve processes, and directly influence product quality.
Collaborative Environment: Work alongside skilled tradespeople, engineers, and production teams to build specialized equipment for customers across North America.
Professional Growth: Continue developing your expertise while contributing to improvements in our manufacturing and testing processes.

What We're Looking For

An experienced refrigeration professional with strong technical knowledge and practical troubleshooting abilities.
A safety-conscious individual who takes pride in delivering high-quality workmanship.
Someone who can confidently interpret technical drawings, schematics, and equipment specifications.
A proactive problem-solver who can identify issues, recommend solutions, and work with minimal supervision.
A dependable team player who communicates effectively and supports a collaborative working environment.

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.

Qualifications & Education

Secondary school diploma or equivalent.
Minimum 3–5 years of hands-on experience in commercial or industrial refrigeration, HVAC installation, servicing, commissioning, or related work.
Ontario 313A Refrigeration and Air Conditioning Systems Mechanic certification strongly preferred, or equivalent relevant trade experience and qualifications.
Valid G1 or G2 Gas Technician certification strongly preferred.
Valid ODP (Ozone Depletion Prevention) certification required for duties involving regulated refrigerant handling.
Strong working knowledge of refrigeration cycles, refrigerant piping, compressors, expansion devices, controls, and system operation.
Demonstrated experience with refrigeration system installation, pressure testing, evacuation, charging, commissioning, and troubleshooting.
Experience with gas-fired heating equipment, burners, gas trains, and combustion systems considered a strong asset.
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.
Knowledge of applicable Ontario gas regulations, refrigeration standards, and safe refrigerant handling practices.
Excellent troubleshooting, analytical, and problem-solving skills.
Ability to work independently while collaborating effectively with Production, Engineering, and Quality teams.
Strong attention to detail, organizational skills, and commitment to quality workmanship.
Ability to stand for extended periods, work in a manufacturing environment, and safely lift or move equipment and materials as required.
Comfortable working with pressurized systems, refrigerants, open-flame equipment, and electrical components while following established safety procedures.
