When an AHU needs attention

  1. 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. 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. 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.

  • You 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. 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. 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. 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. 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.

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.

Does AHU servicing disrupt guest and resident comfort?

Yes, so we coordinate with management to service during off-peak hours or night shifts, keeping air flowing to all rooms.

Luxury buildings need strict air quality standards, how do you ensure this?

We inspect filters, coils and dampers to high precision, ensuring fresh and recirculated air ratios stay balanced for comfort standards.

Heat loads vary between hotel rooms and halls, how do you handle this?

The AHU has smart dampers that adjust distribution by zone need. Inspecting and tuning them ensures heat loads stay balanced across all areas.

Do we need full power isolation or just the motor disconnect?

Full power isolation from the main control panel is required before servicing to keep the team completely safe.
