AHU maintenance in Al Hamra

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.

Hospital AHUs have precision sensors and automatic controls. Our team checks the sensors, dampers and air valves with high accuracy to keep conditions in line with health standards.

Yes, we respect hospital cleanliness and safety requirements. We use sterilised equipment and filters, and avoid spreading contaminants between wards during servicing.

Yes, Al Hamra's coastal location exposes coils to sea salt and spray. We recommend checking and cleaning coils at least quarterly, especially in hospitals where the load is heavy.

We coordinate with hospital management and medical staff to schedule work during non-critical periods or when patient load is light, and may use temporary units if needed.
