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 Ajawid in south Jeddah hosts modern residential towers, hotels, universities and large clinics that use central chillers. The area experiences intense heat and high humidity, with cooling demand continuous throughout the long hot season from March to October. Chillers run under heavy load and outdoor coils are exposed to dust and light salt spray. Comprehensive regular maintenance of coils, compressor, pumps and controls extends system life and prevents sudden failure during peak demand.
Al Ajawid is a south Jeddah district marked by residential towers, hotels, universities and large institutions with centralised cooling systems.
Large towers and institutions in Al Ajawid run high-capacity chillers rated 100 to 350 refrigeration tons, many in dual configuration for redundancy.
The AC setup in Al Ajawid
- 1
Dual chillers for operational continuity
Large institutions in Al Ajawid typically need two or more chillers so if one fails the other continues cooling.
- 2
Advanced distribution system with multiple zones
Chilled water distributes through a complex network to multiple zones with control valves on each zone to ensure balanced delivery.
- 3
High-efficiency cooling tower
A large cooling tower with multi-stage coils handles the high load from the chillers and improves cooling efficiency.
Before the visit
Before our visit in Al Ajawid
- 1
Notify the entire institution management of the maintenance date
Inform all departments and users of the expected maintenance date and whether any zone may experience temporary shutdown or reduced cooling.
- 2
Confirm safe access to all inspection points
Check that plant room doors, roof access and main pipe locations are safe and easily accessible, and our team can move freely.
- 3
Compile complete performance data and previous readings
Compile all maintenance records, monthly readings and any complaints or observations about cooling so we can accurately compare performance trends.

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.
My university and large clinic need continuous cooling, what is the best maintenance schedule?
We advise monthly service during the hot season and a full inspection before summer begins. If the system is dual we service both chillers alternately.
Outdoor coils get dirty fast from dust, how often do you clean them?
We clean the coils on every maintenance visit and advise extra cleaning every fortnight during peak season because dust blocks airflow.
With dual chillers, how is the load balanced between them?
We check both chillers working together and measure discharge pressure and chilled water temperature from each to verify balanced load.
My university has different cooling loads across floors and halls, how do you manage that?
We inspect control valves and distribution points and take pressure and flow readings at multiple network locations, and suggest load-balancing adjustments if needed.
