About the Role
A top-tier equipment manufacturer is seeking an experienced Heavy Commercial HVAC & Combustion Service Technician to handle startup, troubleshooting, maintenance, and repair of large-scale commercial and industrial heating and cooling systems across the U.S.

Key Responsibilities
HVAC & Refrigeration: Diagnose and service industrial chillers, heat pumps, and hydronics. Troubleshoot complex refrigeration circuits, scroll compressors, valves, and heat exchangers.
Combustion Systems: Service and tune gas, propane, and fuel-oil burners using combustion analyzers. Troubleshoot gas trains, safety shutoffs, and flame safeguards.
Electrical & Controls: Read schematics and diagnose 208–575V three-phase systems, VFDs, motors, sensors, and controllers.
Startup & Commissioning: Conduct factory-authorized startups, verify installation requirements, test system safeties, and train facility operators.
Documentation: Complete accurate electronic service reports and photos. Assist with factory testing and technical projects when not traveling.
Qualifications
Hands-on experience with heavy commercial HVAC, industrial refrigeration, burners, or boilers. (strong HVAC techs with basic combustion exposure—or industrial combustion techs with strong electrical skills—are encouraged to apply).
Solid skills in three-phase electrical troubleshooting and reading schematics.
EPA Section 608 Universal Certification preferred.
Valid driver’s license with an acceptable driving record.
Willingness to travel Mon–Fri frequently and work overtime while on the road.
Physical ability to lift up to 50 lbs, climb ladders, and work in varied site conditions.
