COLD ROOM & WALK-IN FREEZER ENGINEERS — LONDON
Call an engineer: 020 8050 4009
We repair commercial cold rooms and walk-in freezers that aren’t holding temperature, are icing up or have stopped altogether. We work for restaurants, hotels, food retail, supermarkets, dark kitchens and other commercial sites. Our F-Gas certified engineers diagnose and repair faults across London and surrounding areas, and we’re available 24/7 with same-day call-outs.
Commercial sites only — we don’t do domestic work.
Fastest way to get help
No call centre script. Tell us the make and model, what the room is doing and the current temperature.
Common faults we fix
Most cold room and walk-in freezer breakdowns come down to a handful of causes. Tell us the symptoms and we’ll help narrow it down before the engineer arrives.
More on our cold room services, or read the warning signs of a cold room breakdown.
Room running warm or drifting above set point. We trace whether it’s refrigerant, airflow, controls or the condensing unit.
Iced coils from failed defrost heaters, timers or settings, blocked airflow or warm air getting in.
Units that won’t start, keep tripping, run noisy or overheat. Electrical and mechanical faults diagnosed on site.
Worn or split gaskets, dropped doors and failed frame heaters that let warm air in and ice form.
Evaporator and condenser fan motors that have stopped, seized or become noisy.
Faulty controllers, probes and displays, and alarms that keep sounding or won’t clear.
Leak detection and repair by F-Gas certified engineers, then the system recharged correctly.
Frozen or blocked drain lines and failed drain heaters leaving water or ice on the floor.
Systems switching on and off too often, which wears the compressor and lets temperatures swing.

FAQ
Straight answers to the questions we hear most from kitchens, food retailers and other commercial sites.
Yes. We’re available 24/7 and offer same-day call-outs across London. If your cold room or walk-in freezer is down, call 020 8050 4009, or WhatsApp photos and fault codes so the engineer arrives prepared.
The usual causes are an iced-up evaporator, a failed fan, low refrigerant from a leak, a dirty or failing condensing unit, a faulty controller or probe, or warm air getting in through worn door seals. Check the door closes and seals properly and that nothing is blocking the evaporator or condenser. If the temperature is still rising, call us and an engineer will diagnose the fault.
Ice usually builds up when the defrost isn’t working (a failed heater, timer or controller setting), when moist air gets in through damaged seals or a door left ajar, or when the drain line freezes. Ice on the evaporator blocks airflow, so the temperature creeps up. Don’t chip it off the coils, as that can puncture them. Call us to find and fix the cause.
Our engineers work on most makes and types of commercial cold rooms, walk-in freezers and condensing units. Tell us the make and model when you call, or send a photo of the rating plate, so the engineer comes prepared.
Yes. Planned maintenance is available and helps catch worn seals, iced coils, dirty condensers and failing parts before they cause a breakdown. See our services page for details.
Keep the door shut as much as possible, note the current temperature, and move high-risk stock to another cold store if you can. If the evaporator is iced, don’t try to chip the ice off.
