Cold rooms in Old Airport

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.

We assess all units, coils, seals and controllers in one round. The time depends on the number of rooms and their condition, and we set the schedule at the first visit.

We regularly handle large warehouses and follow strict safety standards. We inspect the roof and platforms beforehand and coordinate safe climbing times with warehouse management.

We clean coils and filters on a more frequent regular schedule here than in other districts. We recommend monthly or bi-monthly maintenance instead of quarterly to keep efficiency high.

Yes, we inspect wiring and connections very carefully. We recommend strong independent voltage stabilisers for each refrigeration unit and separate electrical circuits to shield from sharp fluctuations.
