Know the Warning Signs

Symptoms That Mean You Need Reefer Unit Repair

⚠

Temperature climbing above setpoint

The most critical symptom. If the box temperature is rising toward the alarm threshold and the unit is running, the refrigeration system has lost capacity. Causes include low refrigerant, a failing compressor, dirty coils, or a restricted metering device. In Florida's 95-degree ambient heat, a marginal system fails faster.

⚠

Unit won't start

The reefer engine cranks but doesn't fire, or doesn't crank at all. Fuel problems (clogged filter, air in the lines, empty tank), battery issues, glow plug failure, or a seized compressor can all prevent starting. Every minute the unit is down, your cargo temperature rises — especially in a South Florida parking lot in summer.

⚠

Short cycling

The unit starts, runs briefly, then shuts down and restarts. This indicates a refrigerant pressure issue (high head pressure from dirty condenser, low suction pressure from low charge), an electrical control problem, or a safety switch tripping and resetting.

⚠

Unusual noise

Compressor knocking, bearing squeal, loose belts slapping, or vibration from worn mounts all signal mechanical problems that will get worse. A compressor making metallic noises is close to failure.

⚠

Frost or ice buildup on evaporator

A solid block of ice on the evaporator coil means the defrost cycle isn't working. Without proper defrost, airflow is blocked and the unit can't maintain temperature. Causes include a failed defrost heater, a thermostat that doesn't initiate defrost, or a damper that doesn't redirect hot gas.

⚠

Alarm codes on the controller

Carrier and Thermo King controllers log specific alarm codes that identify the failing component. Alarms for high discharge pressure, low suction pressure, high engine temperature, low fuel, and sensor failures all require diagnosis.

Root Cause Analysis

Common Causes of Reefer Unit Failure

Diesel engines are built for a million miles — but these conditions accelerate wear and cause premature failure.

!

Refrigerant leaks

Vibration, thermal cycling, and corrosion create leaks at brazed joints, flare connections, and compressor shaft seals. Florida's salt air accelerates corrosion on evaporator and condenser coils. Low refrigerant reduces cooling capacity and eventually damages the compressor.

!

Dirty condenser coils

The condenser rejects heat to the outside air. When it's clogged with dirt, pollen, cotton from loads, and debris (all abundant in Florida), it can't reject heat efficiently. Head pressure rises, the compressor works harder, and efficiency drops. In West Palm Beach's heat, a dirty condenser is the difference between holding temperature and not.

!

Fuel system contamination

Reefer diesel engines use the same fuel tanks that suffer from Florida's water condensation and microbial growth issues. Clogged fuel filters and water in fuel cause hard starting and stalling — right when you need the unit most.

!

Belt wear and tensioner failure

The serpentine belt drives the compressor, alternator, and water pump. A worn belt slips, reducing compressor speed and cooling capacity. A failed tensioner allows belt flapping and premature wear. Florida's heat hardens and cracks belts faster.

!

Electrical connection corrosion

Reefer units are mounted on the front of the trailer, exposed to full road spray and weather. Florida's humidity and salt air corrode every electrical connection, from the controller plugs to the engine sensors.

!

Engine wear

The reefer diesel engine accumulates hours fast — especially in Florida where it runs nearly continuously. Engine wear reduces power output, which reduces compressor capacity, which reduces cooling ability.

How We Work

Our Diagnostic Process

We don't guess at parts — we diagnose the root cause before turning a single wrench.

01

Alarm code retrieval

We connect to the Carrier or Thermo King controller and pull all active and logged alarm codes. The alarm history tells us not just what's wrong now, but what's been developing over time.

02

System pressure analysis

We connect refrigerant gauges and read high-side (head) and low-side (suction) pressures. These pressures, compared to ambient temperature and box temperature, tell us the condition of the compressor, metering device, condenser, and evaporator.

03

Engine diagnostics

We check engine RPM, fuel pressure, coolant temperature, and oil pressure. A reefer engine that can't maintain rated RPM under compressor load won't pull temperature.

04

Electrical system testing

Battery voltage, alternator output, starter current draw, and sensor readings. We check for corroded connections that cause intermittent faults.

05

Airflow verification

We inspect condenser and evaporator coils for blockage, verify fan operation and rotation, check damper positions, and confirm proper defrost operation.

Our Standards

Our Repair Approach

Leak repair and recharge

We locate refrigerant leaks using electronic detectors and UV dye, make the repair, evacuate moisture from the system, and recharge to the correct weight. We don't just add refrigerant to a leaking system — that's a temporary fix that damages the compressor.

Condenser and evaporator cleaning

We clean coils on-site using appropriate methods for the condition. Light debris gets blown out with compressed air; heavy buildup requires chemical coil cleaner. Clean coils restore capacity immediately.

Engine service

Fuel filter replacement, fuel system bleeding, glow plug replacement, belt and tensioner replacement, and other engine services that restore reliable starting and operation.

Component replacement

Compressor, condenser fan motors, expansion valves, solenoid valves, sensors, and controllers — we source and install Carrier and Thermo King parts for both current and older model reefer units.

Pre-trip preparation

Before a long haul, we perform a complete reefer inspection and pre-cool verification to ensure the unit will hold temperature for the entire trip.

☀️ South Florida Conditions

Florida-Specific Considerations

Running a diesel engine in South Florida is different from running one anywhere else. Year-round heat, humidity, and salt air create unique challenges our technicians are specifically trained for.

Maximum heat rejection demand

When ambient air is 95 degrees and pavement radiates 140+ degrees, the condenser has to reject heat into already-hot air. This is the worst-case scenario for cooling system capacity. A reefer unit that holds -10F setpoint easily in winter may struggle to maintain 35F in a West Palm Beach summer.

Continuous operation

Unlike northern climates where the reefer gets breaks during cool weather, Florida reefer units run at or near maximum capacity year-round. This accelerates wear on the compressor, engine, and all mechanical components.

Produce and perishable cargo

Palm Beach County is a major distribution hub for produce, seafood, and perishable goods. A reefer failure in transit means cargo rejection at the receiver — losses measured in tens of thousands of dollars.

Salt air corrodes coils

Trucks running coastal routes see accelerated corrosion on aluminum condenser and evaporator coils. Coil degradation reduces heat transfer efficiency and eventually creates refrigerant leaks.

Fuel quality in reefer tanks

Reefer fuel tanks are small and may not turn over fuel as quickly as the main tractor tank. In Florida's heat, fuel sitting in a small reefer tank is particularly susceptible to water condensation and microbial contamination.

Frequently Asked Questions

How quickly can you respond to a reefer emergency in West Palm Beach?
Reefer emergencies are time-sensitive because your cargo is at risk. We prioritize reefer calls and typically arrive within 30 to 60 minutes in the West Palm Beach area. If your temperature-sensitive load is at stake, call 561-475-8052 immediately — we treat reefer breakdowns as high-priority calls.
Can you recharge refrigerant on-site?
Yes. We perform leak detection and refrigerant recharge on-site for both Carrier Transicold and Thermo King units. If there's a leak, we find and repair it first, then recharge the system to the correct level. Running a reefer with low refrigerant damages the compressor and won't maintain proper temperature.
Why is my reefer unit not holding temperature?
Common causes include low refrigerant from a leak, a failing compressor, dirty condenser coils (Florida's dust and pollen clog them quickly), a malfunctioning thermostat or controller, damaged door seals allowing warm air infiltration, or a worn evaporator fan. In Florida's extreme heat, even minor efficiency losses can prevent the unit from holding setpoint. We diagnose the specific cause on-site.
Do you work on both Carrier and Thermo King units?
Yes. We service Carrier Transicold and Thermo King refrigeration units — the two dominant brands in the industry. We diagnose electrical faults, repair mechanical components, service fuel systems (reefer diesel engines), and address refrigerant issues on both platforms.
How do I know if my reefer needs a compressor replacement?
Signs of a failing compressor include inability to pull temperature down to setpoint, unusual noise from the compressor area, excessive vibration, oil leaks around the compressor, and high head pressure readings. A compressor that cycles on and off rapidly may have internal valve damage. We test compressor performance on-site and recommend repair or replacement based on our findings. Call 561-475-8052.
