Chiller maintenance in Al Shiraa

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.

The chiller is the sole source of chilled water distributed to every floor and unit, so any fault in the compressor or condenser coils stops cooling to the entire building at once.

Coordinate with the building or hotel management in advance; they arrange roof access and the key to the chiller room, and sometimes a staff member escorts us for safety.

Chillers in tall buildings face higher thermal stress at peak summer, especially if the condenser coils are clogged with dust or coastal salt, so monthly checks and regular cleaning are essential.

The chilled-water pressure may be falling due to compressor wear or clogged distribution pipes or a chilled-water pump fault; pressure and flow testing pinpoints the exact cause.
