Overview

XNRGY Climate Systems designs and manufactures advanced cooling systems for data centers and other mission-critical environments. Our field service team starts up, commissions, troubleshoots, and services high-performance air-handling equipment at customer sites across the United States.

About the Role

The Sr. HVAC Technician – CRAH is responsible for installations, commissioning, service, and complex troubleshooting of custom air handling units and computer room air handlers. This technician verifies that fan arrays, controls, sensors, filtration, chilled-water coil controls, and building-management-system interfaces operate as designed. The role works independently at customer sites and coordinates closely with customers, project teams, controls partners, and other field technicians.

Travel and Location

• This is a field-based position with frequent travel to customer facilities and data center projects in Kenosha, Wisconsin, and nearby areas.

• Typical assignments follow either a two-weeks-in-the-field / one-week-home schedule or a three-weeks-in-the-field / one-week-home schedule, depending on project needs.

• The technician must be comfortable working at active construction and operating sites and coordinating travel around project schedules.

Why Join

• Work on custom cooling equipment supporting next-generation data centers and other critical facilities.

• Take ownership of field start-up, commissioning, and service work with opportunities to build technical depth and mentor other technicians.

• Earn additional compensation through overtime and travel, based on hours worked and applicable company policies.

• Join a growing service organization supporting projects across the United States.

Key Responsibilities

• Perform delivery inspections of air-side equipment, document condition, and record damage with clear written notes and photographs.

• Verify installation readiness, including unit clearances, filters, plenum and duct connections, and condensate arrangements before start-up.

• Check electrical supply, fan rotation, and safety devices; identify deficiencies and coordinate corrective action with the appropriate site team.

• Configure and address electronically commutated (EC) fans, verify fan-array addressing, and confirm controller network settings and connectivity.

• Verify temperature and humidity sensors and document calibration results; inspect filtration installation and any fitted disinfecting filtration system.

• Commission air-handler controls integration with the building management system (BMS), including point-to-point verification and completed records.

• Commission fan-array control and verify specified N-1 redundancy behavior using approved procedures.

• Measure and verify airflow, static pressure, and fan performance against approved design criteria and project documentation.

• Commission chilled-water coil control valves and verify capacity-control operation across the required operating range.

• Troubleshoot mechanical, electrical, controls, communication, and air-side performance issues using drawings, wiring diagrams, control sequences, technical manuals, a laptop, and appropriate test instruments.

• Complete pre-functional, commissioning, point-to-point, calibration, performance, and service records accurately and at the point of work.

• Communicate equipment status, deficiencies, risks, and next steps to customers and internal project teams; provide clear turnover information.

• Share technical knowledge with junior technicians and support consistent, safe execution of field procedures.

Required Qualifications

• At least 7 years of hands-on commercial or industrial HVAC field service, start-up, or commissioning experience, including substantial work with air handlers, CRAH/CAHU equipment, or fan arrays.

• Demonstrated ability to commission and troubleshoot EC fan arrays, HVAC controllers, sensors, and BMS-connected equipment.

• Working knowledge of airflow, static pressure, fan performance, filtration, condensate management, and chilled-water coil control.
