Cold rooms in Al Shama'il
In Al Shama'il, north-east Jeddah, distribution centres and large maintenance workshops rely heavily on high-capacity cold rooms. Alrabih's team diagnoses cooling failure and treats the evaporator, condenser, controller and seals to maintain stable temperatures.
- Accurate diagnosis
- Clean evaporator
- Sealed door

When your cold room needs attention
- 1
Room not holding temperature
The temperature climbs slowly even though the unit keeps running, or the products inside are warmer than they should be. The cause could be the evaporator, condensing unit, refrigerant level or controller, and only a site check tells which.
- 2
Evaporator icing up and stopping
Ice builds on the evaporator until airflow stops and cooling fails. The cause is usually in the defrost circuit, its sensor or the evaporator fan. Jeddah's humid air speeds up icing when anything in that circuit is not working correctly.
- 3
Door letting cold air escape
A worn or deformed door seal lets warm humid air in, overloading the refrigeration unit and speeding up evaporator icing. If the door frame heater has failed, moisture builds on the frame and the door becomes hard to open.
Who it's for
Running a restaurant or central kitchen cold room
We check the evaporator, defrost circuit and door seal in your kitchen cold room and fix any fault before your food stock is put at risk.
Ask on WhatsAppOperating a freezer room in a warehouse or retail outlet
We find the cause of temperature loss in your freezer room, inspect the rooftop condensing unit, controller and alarm, and complete a full running test before we leave.

- Controller and temperature alarm
How we work
How we work
- 1
Describe the fault
WhatsApp us what you see: the temperature showing on the controller, whether the unit is running or not, and the type of stock inside the room.
- 2
Site check and diagnosis
The technician checks the evaporator, condensing unit, defrost circuit, controller and door seal, then identifies the actual cause of the temperature loss before starting any work.
- 3
Repair and replacement
We fix what the diagnosis found: clean the evaporator, repair the defrost circuit, replace the seal or adjust the refrigerant charge to the type written on the unit nameplate.
- 4
Test and handover
We run the room and watch the temperature until it reaches the set value, confirm the alarm and controller are working, then hand you a report of what was done.
Systematic maintenance or a quick temporary fix?

What sets this district apart
Al Shama'il is an expanding industrial zone with logistics centres, repair shops and assembly facilities; most buildings are modern with large footprints. Cold rooms sit in distribution hubs and specialist warehouses, where intensive daily work means system failures hit productivity quickly. The region's high heat and humidity accelerate wear on evaporators and condensers, demanding regular inspections and swift repairs.
Al Shama'il lies in north-east Jeddah, an expanding industrial zone housing logistics hubs and large workshops.
Cold rooms in Al Shama'il are typically industrial-grade units with high capacity and advanced control systems serving intensive logistics operations.
The AC setup in Al Shama'il
- 1
Industrial units with ultra-high capacity
Most Shama'il cold rooms are designed for continuous operation and bulk storage, with very powerful evaporators and compressors.
- 2
Smart controls with remote monitoring
Modern units in logistics centres have smart controllers enabling remote temperature monitoring and instant alerts if the temperature drifts.
- 3
Powerful external condensers on expansive roofs
Shama'il buildings offer wide roofs and good ventilation for mounting powerful condensers that handle heavy load and outdoor heat.
Before the visit
Before our visit in Al Shama'il
- 1
Confirm the electrical circuit diagram is available
Request the unit's electrical schematic before the visit so the team can safely isolate it and work confidently.
- 2
Coordinate with operations about unit downtime
Industrial cold rooms are critical to operations, so inform operations about the repair time and expected restart window.
- 3
Prepare a safe power point nearby
Ensure a safe power outlet near the unit is available for the team's testing and repair equipment.

FAQ
Questions about Cold rooms
Why does the temperature rise even though the unit runs all the time?
Continuous running does not mean correct operation. Common causes include a refrigerant leak that reduces the charge, heavy frost on the evaporator coil blocking airflow, or a fault in the rooftop condensing unit raising head pressure. A site survey identifies the actual cause before any work begins.
How do I know if the defrost cycle is working properly?
Clear signs of a defrost fault include thick frost covering the full evaporator coil, a gradual temperature rise while the unit keeps running, and water pooling on the floor instead of draining away. The check covers the heater element, the defrost sensor and the controller, as the fault can lie in any of these parts.
What does a preventive visit for a cold room cover?
A preventive visit covers a pressure check on the refrigeration circuit, cleaning the condenser and evaporator coils, inspecting door seals and frame heaters, testing the controller and alarm, and checking copper pipe connections. The aim is to find a developing fault before it affects the room temperature and the stock inside.
What is the difference between a preventive visit and a repair visit?
A preventive visit is carried out on a unit that is running normally: the purpose is inspection, cleaning and finding early signs of wear before they become a breakdown. A repair visit is requested when an actual fault appears, such as a rising temperature, a stopped compressor or excessive coil icing. Diagnosis comes first, then the required work is defined.
Does Jeddah's rooftop heat affect the condensing unit's performance?
Yes. In summer, Jeddah rooftop surfaces reach very high temperatures, which raises condensing pressure, stresses the compressor and reduces cooling capacity. Regular cleaning of the condenser coil to remove the dust and salt that cling to the fins is essential, not optional. A site survey determines whether the unit's position or the airflow around it is making the problem worse.
The cold room loses temperature quickly in Al Shama'il, what could be wrong?
There may be a pipe leak, frost on the evaporator, or a compressor fault. We run a thorough inspection, pinpoint the problem and fix it fast.
Can you work on large industrial cold-room units in logistics centres?
Yes, we have the expertise and tools for large units and advanced systems. We arrange maintenance times with the centre to minimise operational disruption.
Does Shama'il's heat and humidity stress the cold rooms more?
Yes, high heat and humidity increase evaporator and condenser load, reducing efficiency. We ensure all surfaces, fans and external venting are clean and clear.
How often should we schedule cold-room maintenance?
It depends on unit size, daily use and environmental conditions. We recommend quarterly inspection for large industrial systems, with higher frequency if needed.
