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.

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
Harat Al Sham is an old district of closely built blocks mixing shops, commercial stores and residential space, where cold rooms sit in tight confines under the full pressure of daily use. High humidity and salty sea air speed up corrosion of the condensing unit and seals, whilst narrow streets limit rapid maintenance access. Our team checks door seals and pipework carefully because any leak means immediate temperature loss and stock spoilage.
Harat Al Sham sits in Jeddah's historic downtown, an old district of closely built commercial and residential blocks near the popular markets.
Most cold rooms here are small to medium units in meat, fish and poultry shops, with the condensing unit mounted on the facade or a small balcony.
The AC setup in Harat Al Sham
- 1
Small cold room for a single shop
Most cold rooms here are installed in meat, fish and poultry shops with a wall-mounted evaporator and a small external unit.
- 2
Condensing unit on balcony or facade
Tight spaces force condensing units onto small balconies or facades, increasing exposure to sea humidity and salt air.
- 3
Simple control system with mechanical thermostat
Most of the older units here use a simple mechanical thermostat rather than advanced electronic control.
Before the visit

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 is in a cramped shop, how do you reach it for maintenance?
We move carefully in tight spaces and avoid shifting stock when possible. We agree with the shop owner on the best time to work before we visit.
The temperature drops at times, what causes this?
Leaks in the refrigerant lines, damaged door seals or controller faults are common causes. We inspect each component to pinpoint the problem.
High humidity and salt air near the coast, do they damage the condensing unit?
Yes, salt and humidity speed corrosion of the copper and metal parts, so we check the condensing unit regularly and clear salt deposits.
Can you work on condensing units mounted on narrow facades?
Yes, our team is used to working in the tight spaces of Harat Al Sham. We confirm safe access before starting any work.
