Reefer Repair & Thermo King Repair in Inver Grove Heights, MN.

Carrier and Thermo King interfaces

Every controller fault. The two makes do not share codes, tooling, or configuration software — a tech carries both or serves half the fleet.

Certified recovery, vacuum, weighed charge

Any circuit opened. Refrigerant must be recovered rather than vented, and the charge weighed rather than guessed.

Heated-diode or infrared, plus UV dye

Low-charge and repeat top-off calls. Finding the leak is the repair; adding gas is a delay.

High/low side, micron gauge

Standard on all circuit work. Pulling a proper vacuum is what removes moisture before the new charge goes in.

Traceable calibration, downloadable

Verification and dispute work. An independent reading is what settles a rejected-load argument at the dock.

Common Carrier and Thermo King wear parts

Carried so routine failures finish on the first visit rather than becoming a second dispatch.

Coil cleaner, fin comb, wash gear

Capacity complaints in warm weather. Frequently restores full performance with no parts at all.

Standby testing, phase verification

Electric standby faults at docks and cold-storage yards.

Refrigerant handling certification

Federal law requires technicians who service refrigerant circuits to be certified, and prohibits knowingly venting refrigerant to the atmosphere. Recovery equipment is mandatory, not optional — an uncertified tech opening a circuit is committing a violation.

Refrigerant phase-down

High-global-warming-potential refrigerants are being phased down under federal rule, which is why prices move and why newer units run different blends. Charging the wrong refrigerant into a unit damages it and voids coverage.

Sanitary transportation of food

Federal food-safety rules place obligations on carriers moving food under temperature control, including pre-cooling, monitoring, and record retention. Your temperature record is a compliance document, not just a receipt.

Cargo claims and temperature records

In a rejected-load dispute the recorder download is the evidence. A unit that failed with documented pre-cool and monitoring is a very different claim than one with no record at all.

Transport refrigeration emissions

Several states regulate emissions from transport refrigeration units, with registration and reporting obligations that attach to the equipment owner. Requirements travel with the trailer, not the tractor.

Hours and idling rules

Local anti-idling ordinances frequently exempt refrigeration units precisely because the cargo requires them, but the exemption is not universal. Electric standby is the clean answer where a dock supports it.

Give us the code and the commodity

Carrier or Thermo King, the alarm code on the display, the setpoint, and what is in the box. The commodity sets the clock — a frozen Inver Grove Heights load has hours of headroom, fresh produce may have minutes.

A reefer tech, not a diesel mechanic

We dispatch someone certified for refrigerant work carrying your make's software and recovery equipment. A Inver Grove Heights general mechanic cannot legally open the circuit, and half of reefer faults are inside it.

Fixed, verified, and documented

Repair, then a run to setpoint to prove it holds, then the temperature record downloaded for your file. If the unit cannot be saved in time, we move the load to Inver Grove Heights cold storage instead of watching it spoil.
