AHU maintenance in Al Khaleej

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, proximity to the highway means filters and coils need cleaning more frequently, usually every 4 weeks instead of 6 to 8. We will suggest a fitting schedule after the first inspection.

There may be bacterial buildup or mould in the coils or ducts. Cleaning the coils and internal passages of the unit removes this odour and improves air quality.

Most towers in Al Khaleej have a dedicated plant room or roof space for the unit, and we will check access and working space before we start.

Coils need deep cleaning every 8 weeks, and the belt and bearings need checking every 3 months. We will write this into a bespoke maintenance plan after the first visit.
