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.

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.

What sets this district apart
Al Mawaddah features modern medium-sized residential buildings and small to mid-scale office complexes, mostly built recently to modern standards. These buildings do not run under the intense pressure of major hospitals and hotels, but their systems need regular inspections because coastal dust and humidity quickly affect filters and coils. The moderate space and average occupancy means AHUs operate at a steady, sustained pace rather than peaks and troughs.
Al Mawaddah lies in east Jeddah and is characterised by modern medium-rise residential buildings and small to mid-size offices in a neat, planned neighbourhood.
Most buildings here have one or two medium-capacity AHUs with relatively simple distribution ductwork compared to large-scale structures.
The AC setup in Al Mawaddah
- 1
One or two medium-capacity AHUs
Medium-sized residential and office buildings here typically have just one or two AHUs, unlike large-scale complexes.
- 2
Straightforward, direct distribution ducts
Ductwork is typically straightforward and uncomplicated due to the building's moderate size, making inspection and routine maintenance simpler.
- 3
Modern but simple control systems
Most buildings here have digital thermostats and basic sensors without the complex automation found in hospitals or major hotels.

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.
Temperature doesn't drop evenly in the office, is that an AHU issue?
Clogged filters or unbalanced dampers may be the cause. Inspecting the AHU and ducts determines whether distribution is even or needs rebalancing.
Do we need special approval from building management to access the AHU?
Yes, it is best to coordinate with building management beforehand to confirm the AHU location, verify access and arrange for easy entry.
Humidity is high despite the AC running, how do I check if the AHU is working properly?
Clogged cooling coils or blocked filters reduce the system's dehumidification capacity. Regular AHU inspection ensures proper moisture removal.
What is the typical cost of AHU maintenance in a residential building?
Costs depend on unit size, condition and the work required. Send photos of the AHU on WhatsApp for a specific quote.
