Professional chiller servicing
Chiller maintenance in Al Ruhaili
Chiller maintenance in Al Ruhaili keeps the large residential and hotel buildings in this north-east district cooled through the peak summer months. Alrabih's team inspects the compressor, coils, refrigerant pressure, water flow and controls, logging the unit's condition before failure strikes.
- Logged pressures
- Clean coils
- Balanced flow

When a chiller needs attention
- 1
Weak cooling across several floors
When users on several floors complain at the same time, the source is usually the chiller, not the terminal units. We measure the supply and return water temperatures and compare them with actual operating conditions to find where cooling is being lost.
- 2
Condenser coils clogged with dust and salt
Jeddah's hot, humid, salt-laden air deposits a crust on condenser coils and slowly raises condensing pressure until the compressor is overloaded. Early inspection and regular cleaning stop the problem reaching that point.
- 3
A chiller alarm or sudden shutdown
A modern chiller shuts itself down on a pressure, temperature or flow fault. We read the fault log in the control unit and trace the root cause, whether it is in the refrigerant circuit, the water pump or a flow sensor.
Who it's for
Running a factory or warehouse with an existing chiller
We inspect the compressor, condenser coils and chilled water flow and record operating readings so a chiller fault does not stop your production line or spoil stored stock.

We review operating logs, inspect controls, alarms and pumps, and keep cooling even across every floor throughout peak season.

- Refrigerant pressure readings and records
- Chilled water flow and pumps
- Controls alarms and sensors
How we work
How we work
- 1
Review operating logs
We ask for any saved logs or alarms before the visit and note the symptoms you have seen, so the technician arrives knowing exactly what to look for.
- 2
Compressor and circuit check
We measure suction and condensing pressure against the refrigerant type on the unit nameplate, check the compressor thermally and inspect flange joints and heat exchangers.
- 3
Clean coils and check flow
We clean condenser coils of dust and salt deposits, then check chilled water flow through the pipes and verify that the temperature difference between supply and return is within normal range.
- 4
Document and hand over report
We record all readings in an operating report you keep, and we list any immediate recommendations and any points to watch at the next service visit.

What sets this district apart
Al Ruhaili holds relatively modern residential towers, large hotels and some commercial complexes, most over ten storeys and relying on chillers to distribute chilled water to every unit. In summer, the high heat and humidity put intense strain on the chiller, and small faults in the compressor or condenser coils can shut down cooling across the whole building. Regular servicing and logging prevent these failures.
Al Ruhaili lies in Jeddah's north-east, a district of tall modern towers and hotels serving residential and tourism needs.
Most tall buildings here have one or more chillers per zone, with chilled water fed through a network of pipes in the slab and ceiling voids.
The AC setup in Al Ruhaili
- 1
Central chiller serving multiple floors
Most residential and hotel towers in Al Ruhaili have one or more chillers in a plantroom at ground or roof level, feeding chilled water to every unit.
- 2
Chilled water system with cooling tower
Large chillers in the towers need a cooling tower on the roof to reject heat from the condenser, a standard setup in Al Ruhaili's hotels and complexes.
- 3
Secondary air handlers on each floor
Chilled water from the chiller reaches small air handlers on each floor or zone, where it is mixed with return air and fed to the units.
Before the visit
Before our visit in Al Ruhaili
- 1
Ensure access to the plantroom
Confirm that the plantroom housing the chiller is safely accessible, and let us know if it is locked or needs permission from building management.
- 2
Provide any previous maintenance records
If you have old chiller readings or previous maintenance invoices, send them before the visit so we can spot any trends.
- 3
Tell us where the cooling tower is located
If the building has a cooling tower on the roof, let us know its location and how to reach it so we can inspect the coils and water flow.

FAQ
Questions about Chiller maintenance
How do you tell whether the compressor is working properly?
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.
Does Jeddah's climate affect chillers more than other cities?
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.
Do you repair the chiller on site or does it have to go to a workshop?
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.
What goes into the chiller's operating log, and why does it matter?
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.
Can the chiller be serviced without cutting cooling to the whole building?
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.
How do you know if a chiller needs maintenance before it breaks down?
We check the compressor, coils, pressures and flow regularly, logging the readings each time so any early drift shows before failure.
Our building is 15 storeys; is one chiller enough or do we need more than one?
That depends on the number of units and the cooling load; a technical visit confirms the right size and the best way to serve each floor.
Al Ruhaili gets very hot in summer; does that affect chiller efficiency?
Yes, high heat and humidity raise the load on the condenser and compressor, so regular servicing and keeping the coils clean becomes critical in summer.
The chilled water pipes are buried in the slab; how do you check for leaks?
We monitor water flow and pressure readings; any sharp drop signals a leak, and we pinpoint it using pressure trends and temperature readings.
