Why Reefer Maintenance Is Critical for Compliance and Cargo Safety

Transport refrigeration units are subject to strict federal and state oversight. The Federal Motor Carrier Safety Administration (FMCSA) outlines equipment standards that directly affect refrigerated cargo transport, and failure to maintain a properly functioning reefer unit can result in CSA violations, cargo claims, and costly fines. Beyond regulatory compliance, maintaining consistent temperatures throughout transit is essential for food safety standards set by the FDA’s Food Safety Modernization Act (FSMA). A poorly maintained reefer unit puts your cargo, your customers, and your operating authority at risk.

the service are experienced with the technical specifications and diagnostic systems used by the industry’s leading manufacturers. Carrier Transicold’s trailer refrigeration systems and Thermo King units each have unique diagnostic protocols, and our team is trained to work efficiently across both platforms — as well as other commercial TRU brands found throughout the Pacific Northwest and Mountain West freight corridors.
