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 Wisami's modern high-rises in north-east Jeddah are built for comfortable living and rely on central chiller systems that distribute chilled water to every floor. When cooling drops mid-summer in Jeddah's intense heat, the fault is rarely a single split unit but the chiller serving the whole building. Regular inspection of the compressor, condenser coils and refrigerant pressure keeps the system from sudden failure during peak heat.
Al Wisami is a modern north-east Jeddah district marked by mid-rise and high-rise residential towers and hotels served by central cooling systems.
Most residential and hotel towers in Al Wisami run chillers with cooling capacities of 50 to 150 refrigeration tons, housed in a plant room on the basement or roof.
The AC setup in Al Wisami
- 1
Central chiller serving a multi-storey tower
Al Wisami towers use one or more chillers in a plant room that cool water pumped to all building floors.
- 2
Centralised chilled water piping and distribution
Cold water from the chiller flows through insulated piping in the foundations and walls, distributed to terminal units in each apartment or hotel room.
- 3
Central collection and drainage station
Return water from the floors cycles back to the plant room for re-cooling, with a separate drainage system for excess water and condensation.
Before the visit
Before our visit in Al Wisami
- 1
Coordinate the maintenance visit with building management
Inform the tower or hotel management of the inspection date and confirm access keys are available and pumps can be temporarily shut down if needed.
- 2
Verify access to the plant room
Check that emergency stairs, doors and corridors to the plant room on the roof or basement are safe and clear of obstructions.
- 3
Gather any previous chiller service records
If you have older service records or a chiller operating log, send them beforehand so we can compare current condition with its history.

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 often should I service the hotel or residential tower chiller?
Monthly or seasonal maintenance extends the chiller's lifespan and prevents breakdowns during peak demand, especially before the hot summer season. We log the compressor, coils and pressure condition on each visit.
The chiller is on the roof, how do you bring maintenance equipment up?
We coordinate with building management to arrange direct access via emergency stairs or roof access, and schedule visits to avoid disrupting occupants' peak usage times.
Does coastal humidity in Jeddah affect the chiller's outdoor coils?
Yes, coastal humidity and salt spray accelerate corrosion on the condenser coils, which is why we clean the coils regularly and check the integrity of refrigerant and electrical connections.
Some towers have weak electrical supply for the chiller, does that affect performance?
Yes, low voltage reduces compressor efficiency and raises energy consumption. We advise checking the electrical panel and installing a voltage stabiliser if needed, based on our inspection findings.
