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 Sawari is a modern residential district with multi-storey apartment blocks, most fitted with central chiller systems serving all units. These large buildings depend entirely on the chiller's stability through Jeddah's long, hot summer, and any fault in the compressor or condenser coils affects every resident. Routine maintenance keeps cooling efficiency steady and prevents system failure at peak times.
Al Sawari lies in northern Jeddah, a district of modern apartment blocks with regular planning and comprehensive central cooling systems.
Most Al Sawari buildings run high-capacity chillers to chill the water, with the outdoor unit typically sited on the roof or in a dedicated rear yard.
The AC setup in Al Sawari
- 1
Central chiller cooling water throughout the building
Most Al Sawari buildings have one central chiller distributing chilled water to all floors and units.
- 2
Indoor cooling coils in each unit
Each flat contains small evaporator coils linked to the central chiller, with a thermostat to control the temperature.
- 3
Outdoor unit on roof or rear yard
The outdoor unit is typically on the roof or in a secure rear yard, away from the main building entrances.
Before the visit
Before our visit in Al Sawari
- 1
Arrange the visit time with building management
Notify the building management or residents' association in advance so the maintenance does not disrupt the occupants.
- 2
Confirm access to the roof or rear yard
Check that the roof or rear yard access is open, safe and the team can reach the outdoor unit easily.
- 3
Provide chiller and pipe information
Give us details of the chiller type, approximate age, any previous faults and the location of the main electrical panel.

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 we inspect the chiller before summer?
Routine pre-summer inspection is vital to keep the chiller running efficiently. We recommend a full check-up in spring and inspections every two months during the summer season.
Chilled water runs to every floor; how do you check the flow?
We measure water flow by checking the pressure and temperature gauges on the supply and return lines, and clean the water filters if there is any blockage.
Extreme summer heat puts heavy cooling load on the chiller; does this affect maintenance?
Yes, high temperatures increase the condenser pressure, so we inspect the condenser coils closely and confirm the evaporator is clean for best performance.
Are there common electrical issues in chiller systems in these buildings?
Heavy summer electrical load on the compressor can cause voltage fluctuations, so we check the power cable connections, thermostat relays and check for any chemical buildup in the pipes.
