A typical day in Transport Refrigeration involves performing preventive maintenance, diagnostics, and repairs on refrigerated trucks, trailers, or containers, either in a shop or out in the field. You may respond to emergency service calls, handle regular scheduled services, and troubleshoot refrigeration, electrical, or diesel engine systems. Collaboration with fleet managers, dispatchers, and occasionally customers is common to coordinate repairs and ensure vehicles are back in service quickly. The work can be physically demanding and requires quick thinking in time-sensitive situations, but it also offers variety and a strong sense of accomplishment in keeping vital supply chains running smoothly.
