Sonsray’s Preventative Maintenance Program
At Sonsray, we know your equipment drives your business. Our Preventative Maintenance Program is built to keep your machines running strong and your downtime low.
With scheduled services like oil changes, fluid checks, and full inspections, our factory-certified technicians use genuine OEM parts to prevent issues before they start. It’s a smart way to extend equipment life, protect your warranty, and save on costly repairs.

When to Prioritize Maintenance
Preventative maintenance for Thermo King refrigeration units, refrigerated trailers, vans, APUs, TRUs, and Vehicle Powered Units (VPUs) is especially important during peak transport seasons, which often coincide with warmer months when precise temperature control is crucial.
Off-peak seasons, typically during colder months, are the perfect time to perform routine maintenance without affecting operations. Sonsray ensures your refrigeration units are operating at their best—ready to handle the demands of high-temperature environments and long hauls—preventing costly disruptions and ensuring goods are always transported under ideal conditions.
