• Commissioning & Startup Assistance: Support field engineers and mechanical contractors during system startup, refrigerant charging, control board programming, and initial balancing.
• Advanced Field Troubleshooting: Act as a Tier 2/3 technical support point for complex mechanical or electrical issues (e.g., VFD failures, compressor lockouts, BMS integration errors).
• Warranty & Defect Investigation: Evaluate failed components on-site to determine whether issues stem from manufacturing defects, poor installation, or improper maintenance.
• Contractor & Dealer Enablement: Train mechanical contractors and certified installers on proper installation practices, system wiring, and control setups.
• Upselling Controls & Add-ons: Recommend advanced building automation systems (BAS), smart thermostats, variable speed drives, or IAQ filtration upgrades during project design.

Job description

Core Scope of Work

The role centres around four key pillars:

1. Equipment Selection & System Design: Matching building cooling/heating loads with the right chillers, AHUs (Air Handling Units), VRF systems, or boilers.
2. Pre-Sales Engineering Support: Providing technical calculations, submittals, and energy-efficiency estimates to contractors and specifying engineers.
3. Field Troubleshooting & Post-Sales: Assisting on-site technicians with commissioning, startup issues, and complex equipment diagnostics.
4. Product Feedback & Compliance: Ensuring HVAC solutions meet local efficiency standards (e.g., ASHRAE, AHRI, LEED) and feeding field failure data back to manufacturing/R&D.
