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.

What the service covers
- Compressor check and thermal log
- 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.

What sets this district apart
Al Jawharah is a modern district of tall residential and hotel towers that depend entirely on centralised cooling systems, and the chiller here runs a heavy load all year, especially in summer. Regular chiller checks are vital to prevent total system failure in peak heat, because any fault in the compressor or refrigerant leak cuts off cooling to dozens of flats and rooms at once.
Al Jawharah lies in South Jeddah, a modern district of tall residential and hotel towers with unified central cooling systems.
Most towers here rely on one or two chillers in parallel serving the entire building, with the outdoor unit typically in a dedicated cooling room on the roof or basement.
The AC setup in Al Jawharah
- 1
Single or parallel chiller serving the tower
Most residential and hotel towers rely on one or two chillers in parallel pumping chilled water to every floor through a unified distribution network.
- 2
Dedicated cooling room on roof or basement
The chiller, condenser and pumps are housed in a separate cooling room for better thermal insulation and easier maintenance access.
- 3
Chilled water distributed through unified piping
The piping network from the chiller to the fan coils and terminal units is complex and needs regular checks for leaks and blockages.

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.
Our flats lose cooling in summer, where does the problem start?
When all floors lose cooling together, the fault is usually in the chiller, not the split units. Inspecting the compressor, refrigerant and chilled water pressures pinpoints the problem quickly.
Do we need regular chiller checks or only when it breaks?
Regular checks prevent sudden breakdown and extend the chiller's life, especially under peak summer load, and we keep operating logs so you spot any decline early.
Does coastal air and dust affect the chiller's efficiency?
Yes, high humidity and salt in the air near the coast speed up corrosion of the condenser coils, and dust blocks the fins, so regular condenser cleaning is essential in Al Jawharah.
Our chiller is in the basement, are there power or drainage risks?
We check the power grounding and connections before operation, and make sure the condenser drain water runs clear without backing up and damaging the unit or building.
