Your load stays cold. We get there fast.
Mobile reefer unit repair for Thermo King, Carrier, and other refrigerated trailer systems. Specialty techs, real diagnostic gear, 48-state coverage to protect your load.
A reefer alarm is a time-clock starting on every dollar of product in the trailer. Minutes matter.
Refrigerated freight is the most expensive cargo on the road per pallet, and the most unforgiving when the reefer unit fails. A produce load, a pharma shipment, or a frozen-food delivery can lose thousands of dollars of value in an hour of warming. Meanwhile, reefer repair requires a specialty tech who actually understands the unit on the trailer, not a generalist who will spend the first hour reading the manual.
Road Rescue Network routes reefer calls to operators with documented reefer experience on the major unit types. Our specialists carry diagnostic gear for Thermo King and Carrier systems, common refrigerant, and the parts inventory to handle the most frequent failure modes: compressor issues, fan motor failures, refrigerant leaks, alternator problems on the reefer engine, and electronic control faults.
For fleet accounts, every reefer service call logs against the specific unit, so maintenance history compounds over time. Your reefer service data becomes a record you can use for warranty claims, PM scheduling, and end-of-life replacement planning.
Common reefer failures we handle on-site.
Reefer alarm and fault codes
Alarm codes on the Thermo King or Carrier display, engine faults, high-pressure cutoffs, low refrigerant warnings. Diagnostic scanners and code lookup on every reefer service truck.
Compressor and refrigeration system
Compressor noise, cycling problems, lost refrigerant charge, failed valves, and the full refrigeration loop diagnosis. Recharge with proper refrigerant when the leak is found and sealed.
Reefer engine problems
Diesel engine failures on the reefer unit itself. No-start, fuel issues, glow plugs, alternator, battery on the reefer engine. Independent from the tractor engine.
Electrical and control system
Wiring harness damage, control panel faults, sensor replacement, and electronic component work. Our specialists understand the specific control architecture of each major unit type.
Fan motors and airflow
Evaporator and condenser fan failures, restricted airflow, defrost cycle issues that prevent the unit from pulling box temperature correctly.
Fuel system on reefer engine
Water in fuel, clogged filters, failed lift pumps, priming after dry tank. Same issues as a tractor engine but on the smaller reefer engine platform.
From alarm to cold.
Describe the alarm
Read the fault code off the Thermo King or Carrier display and share the unit make and model at intake. The more detail, the faster the right tech dispatches.
Specialty match
Your request routes to a reefer specialist with experience on your unit type. Thermo King and Carrier have different diagnostic tools and failure patterns; we match accordingly.
ETA and quote
The tech confirms arrival window and the diagnostic fee up front. Reefer calls often get priority routing due to load-value sensitivity.
On-site diagnostic and repair
Scanner readout, physical inspection, confirmed failure, and repair. Most common reefer repairs close in under 2 hours from arrival.
Load protected
Work order, parts, and refrigerant usage documented. If follow-up at a reefer shop is needed, the documentation transfers cleanly.

Answers before you call.
Call immediately. Dispatch will route the nearest reefer specialist and you can message them directly on the way to start triage. If the warming is severe, the tech may recommend transferring the load or coordinating a tow to a facility with standby refrigeration. Speed matters.
Most reefer service trucks carry the common refrigerants used in modern reefer units (R-404A, R-452A, R-134a as applicable). Specify your unit type at intake and the dispatcher can confirm parts and refrigerant availability before dispatch.
Yes. The reefer engine is a separate diesel engine, and failures look like any other diesel: no-start conditions, fuel issues, electrical problems. Our reefer specialists troubleshoot and repair the reefer engine on-site.
Refrigerant charging requires EPA 608 certification, which our reefer specialists carry. They recover and recharge the refrigerant per regulation. If the leak cannot be sealed on-site, the unit needs a shop and the specialist documents exactly what was found.
Reefer calls typically carry a higher diagnostic fee and hourly rate than generic mobile repair because of the specialty training and equipment. The operator quotes the diagnostic fee up front, and repair cost follows diagnosis. A warm load often justifies the higher rate easily.
Yes. Fleet accounts can flag reefer service as priority and tag preferred reefer specialists as their go-to operators. Priority routing ensures reefer calls jump the queue when the load is at risk.
