A&B Mechanical operates a specialized 5,000-square-foot fabrication facility in Winnipeg. The shop produces custom HVAC ductwork, ventilation fittings, welded gas headers, process piping manifolds, and structural mechanical supports built to precise jobsite specifications.

In-shop pre-fabrication speeds up construction timelines, reduces jobsite clutter, avoids weather delays during harsh Winnipeg winters, improves safety control, and lowers overall labor costs through precision factory assembly.

Certified crews install heavy-duty industrial boilers, rooftop units (RTUs), commercial chillers, make-up air units (MAUs), cooling towers, high-capacity water heaters, backflow preventers, and complete commercial gas distribution lines.

A&B Mechanical conducts certified hydrostatic (fluid) and pneumatic (air/nitrogen) pressure testing on natural gas, hydronic heating, process piping, and plumbing runs to verify structural integrity and guarantee 100% leak-free performance.

Testing, Adjusting, and Balancing (TAB) measures and fine-tunes air and water flow throughout an HVAC system. A&B Mechanical performs TAB to eliminate hot/cold spots, ensure correct static pressure, optimize airflow, and reduce energy consumption.

Commissioning is the final validation process where A&B Mechanical tests every boiler, air handler, pump, and control unit under full operating conditions to confirm the entire system operates safely, efficiently, and according to original design specs.

All work follows strict Quality Assurance (QA) and Quality Control (QC) protocols managed by certified Red Seal journeypersons, ensuring compliance with CSA standards, SMACNA guidelines, and Manitoba Building Codes.

Yes, certified pressure welders at A&B Mechanical fabricate custom carbon steel, stainless steel, and high-pressure alloy pipe assemblies for industrial processing, steam lines, hydronic headers, and heavy manufacturing facilities.

Yes, A&B Mechanical offers independent testing, balancing, and commissioning services for general contractors and facility managers seeking third-party verification that newly installed mechanical systems meet engineering standards.

Clients receive a comprehensive commissioning package, including pressure test logs, air/water balancing reports, equipment startup check-sheets, warranty details, operation manuals, and code compliance certificates.

Proper commissioning catches installation flaws early, ensures controls are calibrated correctly, prevents short-cycling, maximizes energy efficiency, and stops premature equipment failure before building handover.

Key sectors include industrial manufacturing, food processing plants, healthcare facilities, commercial office towers, multi-family residential developments, and educational institutions across Manitoba.

Yes, all field teams consist of licensed Red Seal plumbers, gas fitters, sheet metal workers, and refrigeration technicians certified in advanced diagnostic equipment, safety procedures, and local provincial regulations.
