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.
Ask on WhatsAppManaging a residential tower or multi-floor commercial building
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.
Planned servicing or waiting for a breakdown?
| Alrabih | The usual way | |
|---|---|---|
| Condenser coils | Cleaned and inspected | Salt and dust build up |
| Refrigerant pressures | Logged every visit | Only checked at breakdown |
| Chilled water flow | Measured and compared | Assumed to be fine |
| Cooling loss | Caught early | Hits the whole building |

What sets this district apart
Al Mawj is a relatively modern southern district with office blocks, hotels and mid-rise residential complexes, most relying on a central chiller system serving all floors. These systems face high load in summer months and need regular inspection of coils, compressor and controls. Scheduled maintenance prevents sudden shutdowns, extends the chiller's life and cuts power use at the same time.
Al Mawj sits in south Jeddah, a district of office towers, hotels and modern residential buildings served by central cooling systems.
Most large buildings here have one or more chillers, with the outdoor condenser unit typically mounted on the roof or in dedicated ground-level plant rooms.
The AC setup in Al Mawj
- 1
Single or multiple central chillers
Large buildings in Al Mawj may have a single chiller or multiple units connected to the same chilled water distribution system serving all floors.
- 2
Compact cooling tower or air-cooled condenser
The outdoor unit is typically a cooling tower or air-cooled condenser mounted on the roof or in a plant room on lower ground.
- 3
Chilled water distribution piped throughout
A network of pipes distributes chilled water from the chiller to air-handling units throughout the building.
Before the visit
Before our visit in Al Mawj
- 1
Coordinate with building or hotel management
Management needs a clear service plan to ensure cooling stays on in guest rooms or offices during the inspection.
- 2
Ensure roof and plant room access is clear
Check that doors and passages to the roof and plant room are open and safe before the visit day.
- 3
Prepare previous maintenance records
Gather past service reports and inspection records so we understand the unit's history and any previous faults.

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 does a chiller in Al Mawj need servicing?
We recommend a full inspection before summer and a mid-season check to prevent shutdown. Frequency depends on unit size and daily use, and a visit confirms the best maintenance schedule for your building.
Can your team easily reach the outdoor chiller unit on the roof?
Access depends on roof design and available space. We agree with building management in advance on the best access route and timing to avoid disrupting the building's operations.
Does Al Mawj's summer heat and humidity put extra strain on the chiller?
Yes, intense heat and coastal humidity raise the load on the coils and compressor. Regular maintenance cleans the coils and checks refrigerant pressures to keep cooling efficient throughout summer.
Do we need to confirm the chiller's electrical circuits before service?
Yes, we check power availability and safe connections before inspection. Let us know in advance if the building has backup power or restrictions on maintenance times.
