AHU maintenance in Al Amwaj

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.

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.

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.

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.

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.

Yes, Al Amwaj's towers and hotels run their AHUs at high daily intensity, and servicing filters, coils, belts and bearings keeps flow balanced and cuts running costs.

Yes, coastal humidity and salt speed up corrosion of evaporator coils and filters in seaside units, so we inspect them more often than inland areas.

Floor temperatures differ when the AHU's coils or dampers are clogged or set wrongly, and we diagnose this by checking airflow and pressure in each zone.

Main AHUs in modern Al Amwaj towers are usually housed in a separate plant room on the roof or in the basement, and we'll need its location to schedule the service visit.
