We are hiring an experienced Commercial HVAC Technical Support Specialist to provide advanced troubleshooting and product support to contractors, field technicians, and internal sales teams.
We are specifically looking for someone with hands-on commercial HVAC service, controls, commissioning, or startup experience. The right candidate must understand how HVAC systems operate in the field and be able to diagnose equipment, wiring, controls, communication, and performance issues through phone, email, and remote support.
This is not a general customer-service role. You will serve as a technical resource for contractors and technicians working with chillers, rooftop units, air-handling equipment, VAV systems, building automation controls, and related commercial HVAC products.
What You’ll Do
Provide technical support for commercial HVAC installation, startup, commissioning, service, and troubleshooting
Diagnose equipment, wiring, controls, communication, and system-performance issues remotely
Guide contractors and field technicians through troubleshooting steps and corrective actions
Review wiring diagrams, control sequences, equipment submittals, specifications, and technical manuals
Assist with BAS integration, DDC controls, BACnet communication, and cross-manufacturer coordination
Support internal sales teams with technical product questions and equipment applications
Coordinate with manufacturers and internal specialists on complex technical issues
Document recurring issues and help improve product training and support processes
