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.

- Condenser coil cleaning
- 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.
Planned servicing or waiting for a breakdown?
| Alrabih | The usual way | |
|---|---|---|
| Condenser coils | Cleaned and inspected | Salt and dust build up |
| Refrigerant pressures | Logged every visit | Only checked at breakdown |
| Chilled water flow | Measured and compared | Assumed to be fine |
| Cooling loss | Caught early | Hits the whole building |
| Fault log | Read and analysed each visit | Ignored until shutdown |

What sets this district apart
Al Hijaz is a modern commercial district with large malls, markets and office towers that all require unified, powerful cooling for thousands of daily visitors. Large malls open from morning until midnight, and the chiller runs at full capacity to keep temperatures at 20 or 22 degrees no matter how hot it gets outside. Any chiller failure means losing tens of millions in daily revenue and driving visitors away, so rigorous preventive maintenance is absolutely vital.
Al Hijaz sits in east Jeddah, a modern commercial district of large malls, markets and office towers.
Large malls here have central chillers exceeding 300 cooling tonnes, running at least 16 hours daily.
The AC setup in Al Hijaz
- 1
Two separate central chillers for mall and towers
The machine room has one powerful chiller for the mall and another for office towers, each with capacity of 300 tonnes or more.
- 2
Massive cooling tower on the roof
A very large industrial cooling tower with powerful fans handles the heavy load from both mall and office chillers.
- 3
Pipe network distributed to hundreds of sections
Main copper pipes and complex branches distribute chilled water to hundreds of shops, restaurants and offices with sensitive pressure and flow balances.
Before the visit
Before our visit in Al Hijaz
- 1
Coordinate with mall and tower management
Alert the mall and office tower management to the inspection date, selecting a time avoiding peak visitor hours or office working hours.
- 2
Compile previous pressure, temperature and flow records
Obtain pressure and temperature readings from the control room and previous weeks to compare with this inspection's results.
- 3
Confirm safe access to machine room and roof
Check that access routes to the machine room and roof are safe and clear of visitors and other obstructions.

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.
The mall opens every day, how do you service it without stopping cooling?
If there are two or more chillers, we can isolate one while the other runs. With a single chiller, we choose a weekly closure time or late night.
With thousands of visitors and intense heat, how do you confirm the chiller can handle this load?
We regularly inspect the compressor, condenser and fans, and assess actual cooling efficiency against the chiller's rated capacity.
Malls are crowded with people, does air quality affect the chiller?
Crowding means extra humidity and heat inside the mall. We ensure air filters and the condenser are cleaned regularly to prevent clogging by dust and moisture.
Do office towers above the mall need separate or shared cooling?
That depends on the design. Some malls have two separate chillers, one for the mall and one for the towers. We inspect both to confirm each section gets what it needs.
