HVAC Commissioning & Field Engineer – Building Systems Expert
HVAC commissioning engineer, field engineer, and service specialist roles converge here. In this position, you orchestrate the entire commissioning lifecycle—planning, functional performance testing, verification, and root-cause analysis—for new builds and retrofits. Your work ensures every control sequence, sensor, and actuator performs flawlessly while energy consumption stays lean.
Key Responsibilities
- Draft comprehensive commissioning plans, schedules, and checklists that align with ASHRAE Guideline 0 and ASTM E2813.
- Conduct on-site functional performance testing of chillers, boilers, VAV boxes, heat pumps, air handlers, and hydronic systems.
- Verify automated control sequences against design intent using BAS interfaces, data loggers, and trending tools.
- Oversee Testing, Adjusting & Balancing (TAB) contractors; validate airflow, water flow, and pressure readings with flow hoods, manometers, and ultrasonic meters.
- Capture anomalies quickly—apply thermal imaging, multimeters, and power analyzers to pinpoint latent faults.
- Perform disciplined root-cause analysis; document findings with cause-effect diagrams and corrective recommendations.
- Produce clear, technically rich commissioning reports—actionable summaries, punch lists, and life-cycle cost impacts included.
- Advise facility managers on optimized setpoints, preventive maintenance, and retro-commissioning strategies.
- Uphold rigorous safety protocols (LOTO, confined space, arc-flash) and promote zero-incident culture.
- Collaborate remotely with design engineers, energy modelers, and controls programmers; travel to project sites 30–60 %.
Required Skills
- Deep hands-on knowledge of HVAC equipment operation, control logic, and diagnostics.
- Proficiency with BAS platforms (Niagara, Tridium, Johnson FX), data loggers, and cloud-based analytics dashboards.
- Mastery of TAB instrumentation—flow hoods, balometers, inclined manometers, rotating vane anemometers.
- Strong command of thermodynamics, fluid mechanics, and psychrometrics.
- Advanced technical writing; ability to translate field observations into concise, client-ready deliverables.
- Familiarity with NFPA 70E, ASHRAE 90.1, and local energy codes.
Preferred Qualifications
- Bachelor’s in Mechanical Engineering or Building Science (PE or CxA credential a plus).
- Five+ years in commissioning, startup, or HVAC service for healthcare, data center, or high-rise projects.
- Experience with remote functional testing platforms and IoT-enabled sensors.
- Working knowledge of energy modeling software (eQuest, EnergyPlus) adds value.
