We understand the urgent nature of refrigeration breakdowns. Our team is equipped with the latest diagnostic tools and extensive experience to quickly identify the root cause of issues, whether it's a minor component failure or a complex system malfunction. We focus on providing effective, long-lasting solutions to restore your refrigeration to optimal working condition.
Common Refrigeration Faults We Diagnose
Commercial refrigeration systems are complex, and a variety of issues can arise, impacting performance and efficiency. Our skilled engineers are adept at identifying and resolving a wide range of common faults that affect cooling, temperature control, and overall system operation.
From issues with refrigerant levels to electrical malfunctions, understanding the symptoms is the first step towards effective diagnosis and repair. We address problems swiftly to mitigate potential losses for your business.
- Inadequate cooling or fluctuating temperatures
- System not starting or running continuously
- Unusual noises or vibrations from the unit
- Ice build-up on evaporator coils or excessive frosting
- Refrigerant leaks, indicated by low pressure or oil traces
- High energy consumption or tripping circuit breakers
- Drainage problems leading to water leaks
- Compressor issues, including overheating or failure to cycle
- Condenser or evaporator fan motor malfunctions
- Control panel errors or sensor failures
Our Fault Finding Process
Our approach to refrigeration fault finding is systematic and thorough, designed to pinpoint problems efficiently and accurately. We combine hands-on inspection with advanced diagnostic tools to ensure no potential issue is overlooked, providing a clear path to resolution.
Upon arrival, our REFCOM certified engineers will conduct a detailed assessment, communicating their findings clearly and recommending the most effective course of action. Our priority is to minimise disruption and get your equipment back online as quickly as possible.
- Initial inspection and gathering of symptomatic information from site personnel
- Visual checks for obvious damage, leaks, or component wear
- Electrical testing of components such as compressors, fans, and control circuits
- Refrigerant pressure and temperature analysis using manifold gauges
- Leak detection using electronic detectors and UV dyes if necessary
- Monitoring of system performance parameters like superheat and subcooling
- Verification of thermostat and sensor calibration and functionality
- Checking condenser and evaporator coils for blockages or cleanliness issues
- Assessment of drainage systems and defrost cycles
- Comprehensive report of findings and recommended repairs
Specialised Diagnostic Equipment
Effective fault finding relies heavily on the quality of diagnostic tools. Our engineers are equipped with industry-leading technology to accurately assess the health and performance of your commercial refrigeration systems. This investment in technology enables us to diagnose complex issues that might be missed with standard equipment.
From digital manifold gauges that provide precise pressure and temperature readings to infrared thermometers for thermal mapping, our tools ensure a detailed and non-invasive diagnostic process. We use equipment that meets stringent F-Gas regulations for refrigerant handling and leak detection.
- Digital manifold gauges for precise pressure and temperature readings
- Electronic refrigerant leak detectors with high sensitivity
- Infrared thermometers for surface temperature analysis
- Clamp meters and multimeters for electrical current and voltage diagnostics
- Thermal imaging cameras to identify hotspots or cold spots
- Vacuum pumps and recovery units for safe refrigerant handling during repairs
- Data loggers for long-term performance monitoring and intermittent fault detection

Frequently asked questions
What areas do you cover for commercial refrigeration fault finding?
We provide commercial refrigeration fault finding services across all of London and within the entire M25 motorway area. Our engineers are strategically located to respond efficiently throughout this region.
How quickly can an engineer attend a refrigeration fault call-out?
We offer emergency call-out services for urgent refrigeration faults. We prioritise rapid response to minimise disruption and potential stock loss for your business. Please call us directly on 07414 254125 for immediate assistance.
Are your engineers qualified to work on all types of commercial refrigeration equipment?
Yes, our engineers are F-Gas certified by REFCOM and possess extensive experience in diagnosing faults across a wide range of commercial refrigeration equipment, including walk-in chillers, freezers, display cabinets, blast chillers, and ice machines, from various manufacturers.
What should I do if my commercial refrigeration system shows a fault?
If your commercial refrigeration system is showing signs of a fault, such as unusual temperatures, noises, or error codes, you should contact us immediately. Avoid attempting complex repairs yourself, as this can exacerbate the problem or pose a safety risk. Try to note down any specific symptoms or error messages to help our engineers diagnose the issue faster.
Can a fault be diagnosed remotely, or do you always need to visit the site?
While some preliminary advice can be given over the phone, accurate commercial refrigeration fault finding almost always requires a site visit by a qualified engineer. This allows for hands-on inspection, electrical testing, and refrigerant analysis using specialised diagnostic equipment to correctly identify the root cause of the problem.
