Commercial refrigeration support built around accurate diagnosis
Prospecton equipment may operate in demanding industrial conditions with long run times, dust, heat, heavy loading and strict access procedures. We inspect both the refrigeration system and the environment in which it operates before recommending repair.
We do not replace components by assumption. A system that is warm may have airflow, control, electrical, defrost, compressor or refrigerant faults. Our technicians inspect the systems linked to the symptoms and explain the practical repair options.

Common refrigeration faults we diagnose
Equipment not holding temperature
Temperature loss may involve dirty condensers, failed fans, blocked airflow, damaged doors, faulty sensors, incorrect controls, weak compressor performance or refrigerant loss. We assess both the refrigeration system and the operating load.
Compressor running continuously
Continuous operation can result from high product load, frequent door opening, poor ventilation, warm-air leakage, condenser blockage, control faults or weak cooling capacity.
Heavy ice on the evaporator
Ice may indicate defrost failure, fan problems, warm-air entry, blocked drainage, sensor faults or refrigerant-system problems. Heavy ice reduces airflow and can cause uneven temperatures.
Controller alarms or unstable readings
We compare the displayed temperature with independent measurements and assess probes, wiring, settings, defrost logic and the connected refrigeration system.
Water leakage
Leaks may come from blocked drains, defrost overflow, damaged trays, condensation or melting ice. Water around electrical components requires prompt attention.
Electrical tripping or failure to start
Possible causes include damaged wiring, contactors, relays, heaters, fan motors, compressor insulation, moisture or protective-device faults.
Unusual fan or compressor noise
Grinding, scraping, buzzing and repeated clicking may involve fan motors, blades, bearings, pipe vibration, starting components or the compressor.
Repeated refrigerant loss
Refrigerant does not disappear during normal operation. Repeated top-ups indicate a leak or sealed-system fault that must be identified.
How we diagnose commercial refrigeration
We collect the fault history, temperatures, set points, controller readings, recent power events and operating conditions. Depending on the system, we may inspect controls, probes, fans, airflow, evaporator icing, defrost components, drainage, door sealing, condenser ventilation, compressor starting and refrigerant-system indicators.
We also consider loading, room temperature, door-use patterns and whether the equipment is correctly sized for the current duty. A strong repair recommendation addresses both the failed component and the conditions contributing to the fault.
Components and systems we assess
Controllers and probes
These manage temperatures, alarms and defrost cycles.
Evaporator fans
Fans move cold air and prevent temperature stratification.
Condenser system
The condenser and fan reject heat and require clear ventilation.
Compressor controls
Contactors, relays, overloads and electronic controls manage compressor operation.
Defrost equipment
Heaters, timers, sensors and controls prevent ice blockage.
Doors and seals
Damaged sealing increases moisture, frost and energy demand.
Drainage
Clear drains remove defrost water and reduce leakage and icing.
Refrigerant circuit
Leak, pressure and compressor assessment determine whether sealed-system work is practical.
Repair options
Repairs may include cleaning condensers, restoring airflow, replacing fans, probes, controllers, relays, contactors, heaters, door seals or drainage components, repairing wiring, correcting refrigerant leaks, regassing after leak repair or evaluating compressor replacement.
We explain the fault, parts involved and expected work before repairs proceed. We do not recommend repeated regassing without identifying the source of refrigerant loss.
Protecting stock and operations
Record current temperatures, minimise door opening and move sensitive stock to functioning refrigeration where possible. Follow internal food-safety, medicine-storage or product-handling procedures. Do not rely on product appearance alone when temperature control has been lost.
What affects repair cost?
Cost depends on equipment type, system size, operating temperature, fault complexity, access, controller requirements, parts, electrical work and refrigerant-system involvement. We assess the equipment before confirming the repair recommendation.
Repair, upgrade or replacement?
Repair is often practical where the cabinet or room is sound and the fault is limited to controls, fans, heaters, seals, drainage or other serviceable parts. Upgrade or replacement may deserve consideration where equipment is obsolete, inefficient, undersized, heavily corroded or repeatedly failing.
Maintenance guidance
- Keep condensers and ventilation areas clean.
- Inspect doors, hinges and seals.
- Monitor controller readings and alarms.
- Keep evaporator airflow clear.
- Check drains for blockage.
- Report repeated icing or unusual noise.
- Record temperature trends.
- Avoid overloading cabinets and rooms.
- Arrange inspection when pull-down becomes slow.
Refrigeration repairs in demanding industrial environments
Industrial refrigeration equipment may be exposed to dust, heat, vibration, restricted airflow and long operating hours. These conditions can accelerate condenser blockage, fan wear, electrical deterioration and compressor stress. We inspect the environment around the equipment because a repaired component will not perform reliably if the original operating problem remains.
We also consider whether equipment is suitable for the present workload. A cabinet or cold room that was adequate for a smaller operation may struggle after production volume or stock turnover increases. Where capacity is part of the problem, we explain this clearly rather than treating repeated overheating or long run times as isolated component failures.
Site safety and service coordination
Industrial sites may require permits, induction, lockout procedures or restricted access to plant areas. Clear coordination with the authorised site contact helps the inspection proceed safely and reduces delays. Customers should never remove electrical covers or bypass safety controls to make equipment run before a technician arrives.
Why correct system capacity and ventilation matter
Refrigeration equipment cannot perform reliably when heat cannot escape or when the system is carrying more load than it was designed to handle. Restricted condenser ventilation, blocked plant areas, excessive product loading and repeated warm-product loading can make a healthy system appear faulty or cause genuine component failure. We assess these conditions as part of diagnosis and explain any operational changes required to support the repair.
Where equipment serves a growing business, we also consider whether the present system remains suitable for the current demand. Repeated long run times, slow temperature recovery and frequent high-temperature alarms may indicate that capacity, not only a failed part, needs attention.
Preparing for service
Provide the site name, gate or security process, induction requirements, plant-room location, loading-zone access and the authorised contact. Confirm any PPE or permit requirements before attendance.
Send the equipment type, current temperature, controller display, fault history, operating duty, stock at risk and whether the system has recently been repaired or regassed.
Send photographs of the controller, equipment data plate, evaporator and condensing unit where safely accessible. Do not remove electrical covers merely to take a photograph.

Commercial refrigeration FAQs
What information should I send when booking?
Send equipment type, location, temperature, set point, controller display, fault history and useful photographs.
Can the system simply be regassed?
No. Refrigerant loss indicates a leak or sealed-system fault that must be assessed.
Should I switch the equipment off?
Switch it off where it trips electricity, smells burnt, smokes, overheats severely or presents an electrical hazard.
Do you repair cold rooms and freezer rooms?
Yes. We diagnose temperature, airflow, control, defrost, door, compressor and refrigerant faults.
Can you quote before inspection?
We can explain cost factors, but accurate pricing depends on diagnosis, parts and system design.
Do you guarantee immediate attendance?
Appointments are arranged according to location, workload and technician availability. We do not make unsupported arrival guarantees.
Can maintenance prevent every breakdown?
No, but it can identify dirty condensers, worn seals, drainage problems, abnormal noise and unstable temperature before a major failure.
