Cold rooms in Al Nuzha

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.

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.

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.

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.

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.

Frequent door opening causes natural heat loss, but if temperature takes too long to recover there is a fault. Our team checks door sealing, evaporator and compressor and fixes what is needed.

We can install a continuous monitoring system linked to your mobile that sends instant alerts if temperature deviates from the set point. This protects stock and ensures food safety compliance.

Steam condenses on cold glass, but mould signals very high humidity and may indicate a door-seal leak. Cleaning the seal and retightening it reduces steam and prevents mould growth.

We provide a comprehensive servicing report documenting all component checks, cleaning and temperature stability. This report supports food compliance, but official requirements are set by local regulatory authorities.
