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 Marwah in central Jeddah holds a mix of large hotels, hospitals and residential towers that require high-capacity chillers. Jeddah's summer is harsh and cooling demand runs 24/7, so any chiller failure affects thousands of residents, patients and visitors. Regular inspection of the compressor, coils, pumps and controls prevents sudden breakdown and provides an accurate record of system condition.
Al Marwah in central Jeddah is home to hotels, hospitals, residential towers and commercial centres, all relying on high-capacity central cooling systems.
Most hotels and hospitals in Al Marwah run dual or triple chillers rated 100 to 300 refrigeration tons to ensure uninterrupted flow.
The AC setup in Al Marwah
- 1
Multiple chillers with redundancy
Large hotels and hospitals in Al Marwah operate two or three chillers in parallel, so if one fails, the others continue operating.
- 2
Branched centralised chilled water distribution
Chilled water branches from the plant room to multiple zones and floors, with control valves on main and sub-branches.
- 3
Cooling tower for outdoor air exchange
The chiller sends return water to a cooling tower on the roof or yard to shed excess heat before re-circulation.
Before the visit
Before our visit in Al Marwah
- 1
Inform the hotel or hospital management of the maintenance date
Contact management in advance to inform them of the maintenance date and expected duration, in case one chiller needs temporary shutdown.
- 2
Prepare pressure and flow records from previous visits
Gather old maintenance records and previous pressure and flow readings so we can compare today's readings and track trends.
- 3
Verify that pumps can be shut down and restarted
Confirm with in-house maintenance that pump isolation valves are safe and automatic controls allow temporary pump shutdown for inspection.

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 hospital and hotel need round-the-clock cooling, how do you prevent chiller downtime?
We schedule maintenance during lighter-load periods and thoroughly inspect every chiller component, pump and control system before the heat season arrives.
How do the dual chillers in our hospital work together?
Dual chillers provide redundancy, so if one fails, the other continues cooling. We inspect both regularly and verify that load is balanced between them.
Temperatures in central Jeddah are very high, how does this affect the chiller?
High inlet air temperature increases load on the compressor and outdoor coils, so we clean the coils regularly and monitor discharge pressure and chilled water temperature.
Chilled water flow through the hospital piping varies, what is the cause?
Variable flow may come from partial blockage in piping, pump malfunction or low refrigerant pressure. We check pumps and control valves and measure flow at multiple points.
