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 Salihiyah buildings mix modern residential towers, hotels and hospitals with healthcare centres, mostly relying on advanced central systems. AHUs here work under high usage pressure because buildings serve diverse purposes, from offices to patient and guest rooms. Coastal air laden with moisture and salts demands regular servicing to keep coils clean and belts and filters sound.
Al Salihiyah lies in east Jeddah, a district mixing residential towers, hotels, hospitals and healthcare facilities.
Most buildings are mid to high-rise, fitted with medium to large AHUs with advanced controls monitoring pressure, temperature and humidity.
The AC setup in Al Salihiyah
- 1
Central medium-capacity AHU
Mid-rise residential towers and hotels here use medium AHUs, managing cool air flow to multiple building sections.
- 2
Precise drainage system for moisture and condensate
High coastal humidity requires robust drainage and fine filtration to prevent water and mould accumulation in coils and dampers.
- 3
Filters calibrated to building health standards
Hospitals and hotels need calibrated filters to reduce particulates and odours to health and comfort standards.
Before the visit
Before our visit in Al Salihiyah
- 1
Pinpoint the exact location of the AHU
The unit may be on the roof or in a hidden plant room; confirm its exact location before the visit.
- 2
Gather temperature readings from different building zones
Before the visit, record temperatures in different floors or building sections; this helps the team identify affected zones.
- 3
Ensure access for tools and replacement parts
The team may need to replace filters or belts; ensure there is safe space and accessibility.

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.
If a Salihiyah hospital reports temperature swings between floors, who should be contacted?
First, our team inspects the AHU, since the problem usually lies there, not in other systems. Clogged coils or poorly adjusted dampers cause these issues quickly.
Does high summer humidity affect AHU efficiency in this area?
Yes, high coastal humidity increases the load on cooling coils and speeds mould and deposit buildup. Clean coils and good drainage are essential for performance and hygiene.
The AHU sits on the hotel roof, does it need protection from salt and wind?
Sea salt and strong winds speed corrosion of belts and metal parts. We check the unit regularly, clean exposed surfaces and replace rusted components.
What is involved in checking air balance across the building's floors?
We measure air pressure and flow at multiple points, and inspect damper openings, filters and coils. This pinpoints where blockage or constriction causes imbalance.
