We're looking for an experienced commercial HVAC Service Technician who does more than turn wrenches on service calls. In this role, you'll own the commissioning and start-up of commercial HVAC installations, making sure new equipment is set up right, runs to spec, and is handed over to the customer ready to perform. You'll work alongside our install crews, project managers, and controls team to take projects from mechanical completion to fully operational systems. If you take pride in getting it right the first time and like being the tech others lean on when new equipment fires up, this is your role.

Lead start-up and commissioning of new commercial HVAC systems, including RTUs, split systems, VRF, chillers, boilers, AHUs, and exhaust and make-up air units

Verify installations meet manufacturer specifications, engineered drawings, and project requirements before start-up

Perform pre-functional checks and functional performance testing, and document results on start-up and commissioning forms

Set and verify refrigerant charge, airflow, gas pressures, combustion, and electrical readings

Coordinate with install crews, controls/BAS technicians, TAB contractors, GCs, and commissioning agents to schedule and complete start-up activities

Identify and correct installation deficiencies, and communicate punch list items clearly to project managers and foremen

Troubleshoot and resolve mechanical, electrical, and controls issues found during start-up

Walk customers and facility staff through system operation at turnover

Maintain accurate start-up reports, test data, and closeout documentation

Support the service department with diagnostic, repair, and preventative maintenance work between project start-ups

Follow all company and jobsite safety policies and model a safety-first approach in the field

Join us and be part of a team dedicated to creating efficient, sustainable, and high-performance environments that make a lasting impact across the industrial, commercial, and institutional sectors.
