HVAC Controls Commissioning Specialist

Monday morning, you leave your Texas home base and head to a data center in Georgia. By noon, you’re on the roof verifying sensor placement, power, and control panel wiring against BAC drawings. That afternoon, you tune VFDs, check safety interlocks, and validate setpoints on a newly installed BAC control system. Midweek, you’re in Florida confirming BACnet/IP and MS/TP communications across a mixed-vendor BMS, isolating a noisy Modbus RTU segment, and documenting corrective actions. Friday, you wrap up training with the customer’s facilities team—walking them through navigation, alarms, preventive maintenance, and basic troubleshooting—before filing detailed startup and expense reports.

As the primary on-site technical resource, you will commission, start up, troubleshoot, repair, and optimize BAC control systems and connected HVAC equipment across the Southeastern United States. You’ll bridge the gap between customers, contractors, field service peers, and BAC Engineering to ensure every installation operates safely, efficiently, and in line with design intent.

• Commission BAC control systems: verify panel installation, sensor placement, power, and BMS connectivity; validate sequences of operation and overall performance.
• Stand up robust BMS communications: integrate BACnet/IP, BACnet MS/TP, Modbus RTU, and Modbus TCP; assist with network configuration and connectivity.
• Diagnose and resolve issues with DDCs/PLCs, VFDs, sensors/actuators, and control panels to maximize uptime and efficiency.
• Lead startups: coordinate schedules, conduct field startups, and confirm operation against design specs, customer requirements, and safety protocols (arc flash awareness, LOTO).
• Train and support: provide on-site guidance, develop user confidence in controls navigation and optimization, and serve as the liaison among all stakeholders.
• Document thoroughly: complete startup and service reports, record configurations and modifications, and feed field insights back to Engineering for continuous improvement.

• Remote, field-based from Texas; extensive travel (typically 50%+), focused on the Southeastern U.S., with occasional travel outside the region (potentially international) as business needs dictate.
• Operate independently in the field while collaborating closely with the Controls Support Lead and the broader Controls Support, Regional/Product Engineering, Warranty, and Quality teams.

• Associate degree in Electrical Technology, Electronics, Mechatronics, HVAC/R, or similar; equivalent military training or relevant industry experience considered. Bachelor’s in Engineering Technology preferred.
• 3+ years in field service, controls/automation, or HVAC commissioning.
• Working knowledge of electrical power/motor controls; VFD configuration/tuning; HVAC/R equipment and commissioning best practices.
• Proficiency with BMS protocols: BACnet/IP, BACnet MS/TP, Modbus RTU, Modbus TCP.
• Ability to read electrical drawings/schematics and apply electrical safety practices (arc flash awareness, lockout/tagout).
• Strong troubleshooting across electrical, controls, communications, and equipment performance.
• Excellent customer service, verbal/written communication, and interpersonal skills.
• Valid driver’s license; ability to travel extensively and work flexible hours as needed.

• Travel typically greater than 50% across the Southeastern U.S.; occasional assignments outside the region and potential international travel.
• Work in varying weather/temperatures; lift and carry up to 30 lbs; occasional weekends and emergency support based on customer needs.

• Expertise: PLC troubleshooting/programming/wiring, HVAC service/maintenance/repair/installation, electrical installation/troubleshooting/repair, rigging and load handling, electrical panel installation, equipment installation and wiring, field service.
• Technologies: Programmable Logic Controllers (PLC).
