How it works

Report the issueTell us what's wrong — reefer alarm, temperature issue, brake problem, or lighting violation. Include trailer make and reefer unit info.
Tech dispatchedWe dispatch a trailer/reefer specialist to your yard, dock, or roadside location with the right tools and parts.
Diagnose and repairYour tech diagnoses the issue, provides a quote, and completes the repair on-site. Reefer units are tested through a full cycle.
Cargo protectedSystem is verified, temperature is holding, and your trailer is road-ready with documentation of work performed.

Dead reefer = dead load. We fix it where it sits.

A failed refrigeration unit means spoiled cargo and lost revenue. Mechanics service Carrier, Thermo King and other reefer units on-site — plus general trailer repair including lights, brakes, doors, and landing gear. No need to deadhead to a shop.

Questions

No estimates. The mechanic diagnoses, quotes, and you approve before any work.

Carrier Transicold, Thermo King and Precedent units, both diesel-powered and electric standby. Tell dispatch the unit model so they send a mechanic who works on it.

Tell dispatch the load is perishable. We don't promise a time before a mechanic accepts; when one does, you see a live arrival time on your status page.

Yes. Our mechanics can perform thorough trailer inspections including brakes, lights, tires, doors, landing gear, and reefer unit operation — at your yard before your driver hooks up.

Fleets in the Phoenix metro can set up an account with dispatch and schedule PM visits at the yard, including reefer units. Each visit is quoted and approved like any other job.

In the app or on your secure status page, by card, after you approve the price. Nobody should ask you for cash at the truck.
