Refrigeration Technician
Cooling the world: Install, maintain, and repair refrigeration and HVAC systems.
What is a Refrigeration Technician?
Refrigeration technicians install, maintain, and repair cooling and climate control systems. They diagnose malfunctions, replace defective parts, and ensure systems operate efficiently. Their expertise is essential for preserving food, maintaining comfort, and supporting various industrial processes.
You spend most of a shift on the production floor: reading panel dials and gauges, turning valves, starting pumps and agitators, and removing jams to keep freezers and lines running. You measure and weigh ingredients, load equipment, sample product characteristics, and record temperatures and amounts on report forms. PPE is routine, and teamwork is constant as you balance hands-on repairs with steady measurement and documentation.
