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.

- Defrost circuit and sensors
- 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.

What sets this district apart
Al Lulu is a relatively modern district with mixed commercial and residential buildings and wider streets than old downtown, yet the shops, restaurants and small hotels relying on cold rooms are densely distributed here. These rooms serve long operating hours and heavy foot traffic through doors, raising strain on the compressor and seals, whilst summer sun exposure on shop facades adds extra pressure to the system.
Al Lulu sits in north Jeddah, a modern district of shops, small hotels and restaurants along main roads.
Cold rooms in Al Lulu shops are typically small to medium units with an external compressor; the outdoor unit sits on the shop roof or outer corner because space is available.
The AC setup in Al Lulu
- 1
Small to medium unit with external compressor
Most cold rooms in Al Lulu shops are compact built-in units with an outdoor compressor on the roof or back wall.
- 2
Condenser fins exposed to dust and sun
The outdoor unit in Al Lulu faces direct sun and dust, so needs regular cleaning to maintain efficiency.
- 3
Digital or mechanical temperature controller
Cold rooms here have temperature controllers requiring precise calibration to prevent product loss from temperature fluctuation.
Before the visit
Before our visit in Al Lulu
- 1
Tell us if the outdoor unit is on the roof
If the outdoor unit is on the shop roof, ensure the roof is safe to access and has enough working space before the visit.
- 2
Confirm the required temperature setting
Tell us the current temperature setting and your target temperature so we can verify the controller settings accurately.
- 3
Schedule the visit outside working hours if possible
The cold room is vital to daily operations, so if possible book the visit after closing or early morning to minimise impact on sales.

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 cold room loses temperature every hour, is that a serious fault?
Temperature loss can stem from a worn door seal, frozen evaporator or controller fault, and needs a site visit to diagnose precisely.
The outdoor unit on my shop roof is sun-exposed, does that reduce cooling efficiency?
Yes, Al Lulu's intense summer sun raises the condenser temperature, so we recommend shading the outdoor unit or regular condenser fin cleaning.
The cold room door opens constantly for customers and staff, how do we maintain the temperature?
Constant door opening loses cold air rapidly, so the door seal must be in excellent condition, and an air curtain or minimising open time helps maintain temperature.
The compressor runs continuously but the temperature won't drop, what's the cause?
There may be a refrigerant leak, blocked evaporator tubes or a faulty expansion valve, all of which require a full system check.
