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.

What sets this district apart
Al Shifa is a modern district hosting first-class hotels, specialist hospitals and large residential projects, all relying on advanced centralised cooling systems that demand precise maintenance. Medical and hotel buildings need high accuracy in temperature and humidity control for guest comfort and patient safety, and the chiller here runs a heavy load year-round. Regular checks of the compressor, refrigerant and water pressures and automated controls are vital to prevent any failure affecting guest comfort or patient safety.
Al Shifa lies in South Jeddah, a modern district hosting hotels, hospitals and large residential projects with advanced cooling systems.
Most hotels and hospitals here run two or more chillers in parallel to ensure continuity, with outdoor units in dedicated cooling rooms or protected courtyards.
The AC setup in Al Shifa
- 1
Multiple chillers in parallel for continuity
Hotels and hospitals run two or more chillers in parallel with one as standby, ensuring cooling never stops during maintenance or failure.
- 2
Dedicated cooling room to hotel and medical standards
The cooling room is designed with excellent thermal insulation and unified temperature monitoring and ventilation to prevent any fluctuation in central cooling.
- 3
Advanced sensor systems for automated control
Hotels and hospitals are equipped with precise digital sensors measuring pressures, temperature and flow, automatically controlling chiller operation based on load.
Before the visit

Coordinate the inspection time with management
Ask the hotel or hospital management to choose the best time for chiller inspection without disrupting guests or patient care.
- 2
Provide maintenance history and past failure logs
Give us the chiller's history and any past problems so we understand failure patterns and the system's heavy load exposure.

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 hospital needs precise cooling, how do you prevent temperature fluctuations?
We inspect the automated controls and sensors, confirm temperature and refrigerant pressure accuracy, and test the system's response when cooling loads change.
The hotel is fully booked, can you check the chiller without shutting down cooling?
Yes, if you have two chillers in parallel, we inspect one while the other runs. Otherwise we schedule maintenance during the lowest occupancy hours.
Does salt and humidity affect the automation precision?
Yes, high humidity and salt accelerate corrosion of sensor terminals and control wiring, so we regularly inspect and clean the contacts and terminals.
We need detailed cooling logs for hotel compliance, how do you help?
We log refrigerant and water pressures, temperatures and loads at each check, and provide the hotel management with a detailed report on system condition.
