Technical Sales Support Engineer

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.

Key Responsibilities

1. Pre-Sales Technical Engineering

• Load Calculations & Equipment Sizing: Analyze architectural blueprints, building layouts, and load requirements to select optimal unit capacities, duct layouts, or hydronic system components.
• Technical Submittals & Proposals: Prepare technical proposal packages, equipment specification sheets, submittal drawings, and compliance documentation for tender bids.
• Engineering Consultation: Consult with mechanical consultants (MEP firms) and contractors to advocate for your brand's HVAC specifications in building designs.
• Energy Efficiency & ROI Modeling: Run energy simulation software to show clients payback periods, energy savings, and life-cycle costs compared to alternative systems.

2. Post-Sales & On-Site Support

• 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.

3. Sales Support & Business Growth

• 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 indoor air quality (IAQ) filtration upgrades during project design.
