Nice To Haves

Journeyman status (Refrigeration and Air Conditioning Mechanic) strongly preferred.
5 years experience in HVAC piping, copper brazing, tube bending, or manufacturing assembly is preferred.
Proven hands-on experience with ACR copper tubing fabrication, bending, fitting, and brazing (with nitrogen purge) strongly preferred.
Knowledge of HVAC manufacturing, refrigerant piping best practices, nitrogen purging, pressure/vacuum testing, and safety procedures an asset.
Experience with sheet metal an asset.

Responsibilities

Study drawings, blueprints, and specifications to determine the layout of refrigerant piping, gas lines, and equipment for air handling units and materials required (including ACR copper tubing).
Measure, cut, bend, deburr, fit-up, and mark reference points for installation of copper ACR tubing, gas lines, and equipment using tube cutters, benders, and hand/power tools.
Fabricate and assemble copper ACR refrigerant piping circuits (liquid lines, suction lines, and associated headers) for DX cooling coils and air conditioning systems.
Perform high-quality torch brazing and soldering of copper-to-copper, copper-to-brass, and copper-to-steel joints using oxy-acetylene equipment, proper brazing alloys/rods, and continuous dry nitrogen purge to prevent internal oxidation, scale formation, and contamination.
Install refrigeration components such as thermostatic expansion valves (TXV), filter-driers, sight glasses, solenoid valves, and associated controls into the piping assembly.
Install, maintain, and service gas heating units and their components, such as burners, valves, and automatic controls.
Conduct nitrogen pressure testing (high-pressure leak testing) on completed piping assemblies; perform leak detection using electronic detectors, soap-bubble solution, or other approved methods; repair or re-braze defective joints as required.
Perform system evacuation/dehydration and vacuum testing on refrigerant circuits using vacuum pumps and micron gauges to achieve and verify specified vacuum levels (typically <500 microns).
Test and replace defective equipment or components.
Test and adjust control mechanisms and check pipes and piping connections for gas leaks using gas detecting devices (and refrigerant leaks using appropriate methods).
Clean brazed joints of flux/oxide and perform final quality inspections to ensure leak-free, code-compliant assemblies.
Other duties as assigned.
