Cold rooms in Abhur Al Janoubiyah

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.

Yes, the high coastal humidity increases condensation inside and can cause mould or corrosion, so we regularly clean the drain pan and check the room's insulation is proper.

Yes, the airborne salt near the coast oxidises copper, so we inspect the lines regularly and maintain the outer insulation to prevent leaks and refrigerant loss.

Heat and humidity together double the load on the condenser and evaporator, so we clean the condenser regularly and check refrigerant levels to ensure the system works efficiently under the combined stress.

We clean the evaporator and condenser in place using tools suited to tight spaces, and coordinate with the bakery owner to choose a time away from production hours.
