Chiller maintenance in Al Jamea

We measure suction and high-side pressure and compare them with expected values for the refrigerant type on the unit nameplate, check the compressor thermally with an infrared camera if needed, and compare current draw with actual load conditions on the day of the visit.

Yes. Jeddah's humid, salt-laden sea air deposits a layer on outdoor condenser coils faster than in dry inland cities. This raises condensing pressure and makes the compressor work harder, which is why coil inspection and cleaning matter more here than in a dry climate.

Most maintenance and common repairs are done on site: coil cleaning, pressure adjustment, sensor replacement, control circuit repair. Work that requires internal compressor rebuilding is identified after inspection and we explain exactly what it involves.

At every visit we record refrigerant pressures, entering and leaving water temperatures, compressor current and any alarms. Comparing these readings visit by visit shows a slow loss of performance, such as a condenser coil starting to foul or a charge running low, before it turns into a shutdown.

It depends on how many chillers the building has and how the hydronic circuit is designed. With a single chiller, a full inspection needs a brief shutdown agreed with you in advance. Where more than one chiller is installed, we schedule maintenance in sequence so partial cooling stays available. The first visit establishes what is possible.

Often yes. When multiple floors lose cooling at once, the fault is usually in the central chiller, not separate units. Inspecting the compressor, pressures and chilled water quickly pinpoints the problem.

Chillers are usually in a plant room on the roof or ground floor. We need to coordinate with building management to ensure safe access to the room and surrounding equipment.

Yes, extreme heat and coastal humidity increase stress on the condenser coils and reduce cooling efficiency. Spring inspections ensure the chiller can handle peak summer demand.

Water or refrigerant leaks reduce pressure and flow. We inspect distribution pipes, joints and pressures to detect any leak before it affects cooling.
