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.

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 |
| Fault log | Read and analysed each visit | Ignored until shutdown |

What sets this district apart
Al Murooj is a rapidly developing district with large shopping malls, hospitals and massive residential blocks standing close together, all relying on powerful central chillers to cool vast areas. These complexes need frequent intensive inspection because any chiller failure stops cooling across dozens of floors or hundreds of shops at once, and regular logs are vital to foresee trouble before peak season hits.
Al Murooj is in far north Jeddah, a rapidly developing district with shopping malls, hospitals and massive residential complexes.
Most shopping malls and hospitals here run multiple chillers in tandem to distribute chilled water to thousands of units.
The AC setup in Al Murooj
- 1
Multiple chillers operating in parallel for large complexes
Large malls and hospitals here operate two or three or more chillers together distributing chilled water to thousands of units.
- 2
Cooling towers to reject excess heat
The large chillers here need sizeable cooling towers mounted on roofs to reject the heat generated by cooling vast areas.
- 3
Complex distribution network reaching hundreds of units
Piping and controls are spread across multiple sections of the complex, each needing separate inspection to spot any performance variations.
Before the visit
Before our visit in Al Murooj
- 1
Coordinate with engineering management before inspection date
Notify the complex's or hospital's engineering department well in advance so they can prepare for any partial shutdown of chillers if needed.
- 2
Gather previous service and maintenance records
If available, send previous maintenance records or pressure and flow readings so we can compare them with today's readings and spot any performance decline.
- 3
Ensure roof and cooling tower access is clear
Verify that the team can safely reach the chiller roofs and cooling towers and that gates and locks are open on the visit day.

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.
For a large shopping mall in Al Murooj, how can we plan chiller servicing without shutting down the shops?
We inspect multiple chillers in stages according to a schedule coordinated with mall management, so only part of the cooling pauses temporarily instead of everything shutting down.
Our chillers serve a large hospital, can we service them without affecting patients?
Yes, hospitals in Al Murooj typically have backup chillers, so we service one while the other runs, coordinating precisely with the hospital's engineering team.
Al Murooj's severe dry heat increases chiller load, do we need more intensive inspection?
Yes, the dry air speeds dust and salt buildup on condenser coils, so we check cleanliness and flow every month or two during summer.
How many chillers should operate together in a large complex?
It depends on the total heat load and the area being cooled. We review each chiller's performance during our inspection and advise any adjustment to the parallel operation.
