Cold rooms kept running
Cold rooms in Al Amwaj
In Al Amwaj, north Jeddah's modern retail and restaurant sector relies on cold rooms to keep stock fresh. Alrabih diagnoses temperature loss, then treats the evaporator, condensing unit, controller and seals so the room holds its set point.
- 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.

- Door seal and frame heater
- Rooftop condensing unit inspection
- 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?
| Alrabih | The usual way | |
|---|---|---|
| Diagnosis | Root cause first | Symptom fixed only |
| Evaporator | Checked and cleaned | Ignored until it stops |
| Door seal | Checked, adjusted or replaced | Left until obviously leaking |
| Controller and alarm | Tested before leaving | Not checked |
| Post-visit report | Written record of work done | Verbal summary only |

What sets this district apart
Al Amwaj is a relatively modern district with shops and restaurants spread across wider spaces than downtown, and cold rooms are usually built into the kitchens or storage areas of larger outlets. The newer building design makes accessing both indoor and outdoor units easier, but the heavy daily use and intense summer heat push these systems harder.
Al Amwaj lies in north Jeddah, a modern commercial zone with shops, hotels and restaurants spread across open spaces.
Cold rooms here typically use remote condenser units mounted outside the building with indoor evaporators, and they draw significant electrical load.
The AC setup in Al Amwaj
- 1
Cold room with separate outdoor condenser
Most shops and restaurants in Al Amwaj have an indoor evaporator and a separate condenser mounted on the roof or exterior wall.
- 2
Long copper runs between indoor and outdoor units
Because buildings are spread across wider areas, the copper lines connecting the evaporator and condenser are longer than in denser districts.
- 3
Digital temperature controller mounted in the room
Modern cold rooms here usually have a digital controller showing the temperature, making it easier to spot faults.
Before the visit
Before our visit in Al Amwaj
- 1
Confirm access to the roof or exterior wall where the unit sits
Let us know before we visit whether the roof is safe to access or if the condenser is elsewhere and needs coordination with building management.
- 2
Empty the room or reduce stock before service
If the service requires the door open for an extended period, it's better to temporarily move the stock so it doesn't suffer temperature swings.
- 3
Show us the location of the main power board
We need to locate the circuit breaker or main control panel for the room to work safely during inspection and servicing.

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.
My new shop in Al Amwaj's cold room loses temperature quickly, why?
The cause could be a door seal leak, ice buildup on the evaporator blocking airflow, or the condenser unit itself needs servicing from heavy use.
Our outdoor unit is on the shop roof, how do you handle the long distance from the room?
The long run between evaporator and condenser affects efficiency, so we inspect the copper line length and insulation at every service to prevent extra heat loss.
Al Amwaj summers are extremely hot, does that stress the cold room?
Yes, the high summer heat increases the cooling load, so we clean the condenser regularly and check the refrigerant level to keep the system running efficiently.
The power circuit is strong but the motor keeps failing, what's the issue?
Repeated failures often stem from the motor overheating because the condenser is not being cleaned, or low refrigerant raising pressure on the compressor and motor.
