When an AHU needs attention
- 1
Weak airflow or smells in the building
A clogged filter or dirty cooling coil cuts airflow and carries a musty smell through Jeddah's humid air. Occupants complain and productivity falls before anyone identifies the source.
- 2
Unusual noise from the plant room
A grinding or vibrating fan usually points to a worn bearing, a slack belt or an unbalanced blade. Delaying the diagnosis can turn a simple fix into a full motor replacement.
- 3
Uneven distribution between zones
One zone too cold and another too warm in the same building usually means a balancing valve not working or a stuck damper. The site survey decides which dampers and valves need adjusting or cleaning.
Who it's for
Your office staff are complaining about poor cooling
We inspect the unit under load, check filters, coil and dampers, and restore balanced airflow across every office zone.
Ask on WhatsAppYou run a medical facility or a large hall
We check the fresh-air intake, dampers and drain pan, verify the drain fall, and issue a written report documenting the condition of every component.

What AHU servicing covers
- Filters checked, cleaned or replaced
- Belts and bearings checked, tensioned
- Coil and drain pan cleaned
- Dampers and fresh-air intake set
- Airflow, noise and motor measured
How we work
How we work
- 1
Unit and system survey
We review the system layout, unit sizes and count, run the unit and record airflow, pressure and noise readings before touching anything.
- 2
Mechanical inspection
We open the access panel and inspect belts, bearings, the fan blade and mounts, recording what needs tensioning or replacing before starting work.
- 3
Clean and adjust
We clean the coil and drain pan, verify the drain fall, adjust dampers and valves, and replace worn filters, belts and bearings as needed.
- 4
Performance check and handover
We run the unit again, measure airflow and compare it with the opening reading, then give you a brief written report of what was done and anything that needs follow-up.
Planned servicing or breakdown response?
| Alrabih | The usual way | |
|---|---|---|
| Filters and coils | Inspected and cleaned regularly | Ignored until failure |
| Belts and bearings | Changed before they fail | Found after the unit stops |
| Air quality | Clean and balanced airflow | Ongoing occupant complaints |
| Condition report | Written after every visit | No record kept |
| Fresh-air intake | Checked and adjusted each visit | Neglected until air quality worsens |

What sets this district apart
Al Sarawat has relatively modern and medium-to-large buildings, including hotels, clinics and commercial centres with advanced central cooling systems. The AHUs in these buildings run under heavy daily load, and dust and humidity collect in filters and coils faster because of dense occupancy and coastal moisture. Regular maintenance of these units is essential for balanced air distribution between floors and to keep indoor air quality in medical and hospitality buildings.
Al Sarawat sits in south Jeddah and holds modern, medium-sized buildings including hotels, health centres and large commercial spaces.
The central cooling systems in these buildings rely on medium-to-large AHUs with multi-stage filters.
The AC setup in Al Sarawat
- 1
Medium-to-large air handling units
The modern buildings in Al Sarawat use high-capacity AHUs with a central ductwork system covering all floors.
- 2
Multi-stage filter system
AHUs here are fitted with primary and secondary filters to capture dust and moisture before distributing clean air.
- 3
Cooling coils under heavy use load
The cooling coils in Al Sarawat's units run at high capacity throughout the day due to dense occupancy and coastal moisture.
Before the visit
Before our visit in Al Sarawat

Confirm the unit location and safe access
Let us know the exact location of the AHU and how to reach it safely via the suspended ceiling or plant room.
- 2
Coordinate with building or centre management
Ensure the building management is notified in advance of the maintenance date, and arrange to stop the unit and secure the work area during the visit.
- 3
Check the condition of filters and coils
Take a photo of the filters and coils if possible before the visit to provide an accurate quote reflecting the scope of work needed.

FAQ
Questions about AHU maintenance
What is the difference between AHU servicing and duct cleaning?
AHU servicing focuses on the mechanical and thermal parts inside the unit itself: filters, coil, drain pan, bearings and dampers. Duct cleaning removes dust from the distribution network. The two jobs use different tools and address different problems, and we offer each as a separate service.
Can the AHU be serviced while the building is occupied?
In many cases yes, depending on the system layout and the number of units. If the building can run a standby unit while we work on another, servicing continues without cutting cooling to any zone. The technician confirms this at the first survey.
How does Jeddah's humidity affect AHUs specifically?
High humidity loads the dehumidification coil harder and speeds up algae growth in the drain pan, blocking the drain much faster than in dry climates. For that reason we give the pan clean and the drain fall check particular attention when servicing AHUs in Jeddah.
When does a bearing need replacing rather than just greasing?
If a bearing shows audible grinding, measurable heat on the housing or radial play when checked by hand, greasing will not fix it. We measure and inspect on site and decide the right action there, because bearing type and size vary from one unit to another.
How do you tell whether the fan needs balancing rather than just lubricating the bearings?
Continuous vibration with a steady hum usually points to an unbalanced fan wheel or dirt build-up on the blades, while an irregular grating sound comes from the bearing itself. The technician measures vibration on the frame and on the shaft; if it is higher on the frame he balances the wheel, and if it is higher on the shaft he inspects the bearing and decides whether to replace it or lubricate it depending on the degree of wear.
My multi-storey commercial centre has uneven temperatures between floors, is AHU maintenance important?
Yes, an AHU clogged with dust and moisture will not distribute air evenly. Servicing the filters, coils and fans restores balance between the floors.
The hotel is near the coast with high humidity, does this affect the AHU?
Yes, coastal humidity speeds up moisture buildup in the cooling coils and drain pans, which reduces the unit's performance. Regular maintenance prevents blockage and corrosion.
The AHU is mounted in the suspended ceiling, how do you reach it for maintenance?
We agree in advance on safe access via the suspended ceiling, and coordinate with the building management to stop the unit and secure the work area before the visit.
How long does it take to clean the filters and coils in a large AHU?
The time depends on the unit size and condition of the filters and coils. Send a photo on WhatsApp for a precise quote that includes labour and materials.
