A reefer unit failure with a temperature-sensitive load is a genuine emergency. Interstate Fleet Services services Carrier Transicold and Thermo King refrigeration units on refrigerated trailers throughout Rock Hill, SC and the Carolinas. When your reefer isn't holding temperature, cycling constantly, losing refrigerant, or won't start, call us. We treat reefer failures as priority calls because we understand what's at stake.
Reefer Emergency: (803) 329-9755Unit not reaching setpoint, temperature fluctuating beyond tolerance, or unit shutting down on temperature alarm. We diagnose the root cause — not just reset the alarm.
Reefer fuel injectors, fuel filters, fuel pumps, and fuel heater failures. A reefer that won't run on diesel strands your load. We diagnose and repair fuel system issues on trailer-mounted units.
Refrigerant leak diagnosis and repair, compressor service, refrigerant recovery, evacuation, and recharge. R-404A and R-134a available. EPA-compliant refrigerant handling.
Control board faults, sensor replacements, wiring repairs, and microprocessor resets. Modern reefer units are highly electronic — we diagnose both mechanical and electronic failures.
Defrost failure causes ice buildup on the evaporator that eventually blocks airflow and causes temperature failures. We service defrost heaters, defrost timers, and drain line systems.
Condenser coil cleaning and repair, evaporator coil inspection, and fan motor service. Condenser fouling is a leading cause of reefer efficiency loss in the hot Carolina climate.
We service Carrier Transicold and Thermo King refrigeration units — the two most common reefer brands in the Carolinas market. We work on trailer-mounted units on dry van and refrigerated trailer configurations.
Common issues include: unit not reaching setpoint temperature, unit cycling on and off excessively, defrost failures, fuel system problems (unit running on diesel), electrical/sensor faults, refrigerant leaks, and compressor failures. Any of these need prompt attention.
Yes. A reefer failure with a temperature-sensitive load is a time-critical emergency. Perishable loads, pharmaceutical shipments, and food products have tight temperature tolerance windows. Call us immediately — we treat reefer failures as priority service calls.
For some repairs, yes. Electrical faults, fuel system issues, and sensor replacements can often be addressed on-site. Compressor failures and refrigerant leaks typically require shop work. We assess on the phone and dispatch appropriately.
Yes. We carry R-404A and R-134a refrigerant for common reefer applications. We recover, recycle, and recharge refrigerant properly in compliance with EPA regulations.
