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
The tall modern towers in Al Lulu rely on one or two chillers to cool every floor, so any cooling loss affects the whole building in peak Jeddah summer. The chiller works under high pressure and heavy load in these residential and hotel towers, so logging the compressor condition, coils and pressures helps avoid sudden costly breakdowns.
Al Lulu sits in north Jeddah, a district of tall modern residential and hotel towers with regular open outdoor spaces.
Most towers here are fitted with large-capacity central chillers serving air conditioning for all floors, with water distribution units on each level.
The AC setup in Al Lulu
- 1
Single or multiple central chillers
Larger towers here may use one large chiller or two or more in parallel, depending on floor count and expected load.
- 2
Centralised chilled water distribution system
Cold water flows from the chiller through shared piping to distribution units on each floor, so any flow interruption affects all units.
- 3
Central automated control unit
Modern towers are fitted with automatic control systems managing temperature, pressures and flow, so sensors and programming must be checked regularly.
Before the visit
Before our visit in Al Lulu
- 1
Coordinate with building management on service timing
Notify the tower or hotel management in advance of the visit, especially if the service requires brief cooling shutdowns on certain floors.
- 2
Confirm safe roof access for the outdoor unit
Check that the roof door can be opened safely and there is clear safe space around the condenser units for the team to work without obstruction.
- 3
Prepare the previous maintenance log
Gather any previous chiller service reports if available, as this helps the team track the unit's condition over time and spot recurring issues.

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 chiller in a residential tower?
We recommend planned service every six months minimum, with closer checks before peak summer. We log the unit's condition each time so you know when urgent intervention is needed.
The chiller outdoor unit sits on the tower roof, is access straightforward?
Yes, most Al Lulu towers allow safe roof access where the condenser units are mounted. We confirm security and safety arrangements before going up.
Does high summer humidity affect the chiller performance?
Yes, Jeddah's high summer humidity increases the load on the condenser coils, raising refrigerant pressure and cutting cooling efficiency. Regular maintenance monitors these effects and keeps performance stable.
Do you check the chiller's electrical connections and circuits?
Yes, we inspect the wiring, connections and automatic electrical controls on the chiller at each service, since the tower needs steady adequate power to run the chiller safely.
