Mall & retail HVAC in Al Hazza'iyah

An open door pushes in hot humid air and spikes the heat load suddenly. We include that load in the design and direct a supply outlet above the entrance to form an air barrier that reduces mixing. The survey confirms which arrangement suits each specific doorway.

Yes. A separate unit per tenant means each shop controls its own cooling and a fault in one unit does not affect the neighbour. It also makes consumption readings straightforward and makes maintenance responsibility clear for each party.

A rooftop packaged unit keeps the condenser and evaporator in one casing above the roof, freeing every inch of shop floor from outdoor units and shortening the duct run. Maintenance happens on the roof without entering the shop, which fits scheduling work outside trading hours.

Rooftop units in Jeddah work in hot, salty and dusty air that strains the condenser and speeds fin corrosion. We specify units with corrosion-resistant coatings and include coil cleaning and compressor and condenser checks in the preventive schedule of every maintenance contract.

The site survey decides. A small shop may need only a concealed unit with directional grilles, while a mall requires a duct network with dampers zoned by area. In both cases the positions of lighting, visitor traffic and entry doors are recorded before supply outlets are placed.

We schedule maintenance in closed hours or low-traffic periods, and strip any unit quickly to minimise downtime.

We design central systems with balanced air distribution that compensates for loss at the doors, and use thermostats at multiple points to adjust the flow automatically.

We select air handlers with high dehumidification capacity and clean coils and ducts regularly to prevent mould and excess moisture in storage and displays.

We mount units in shade where possible and fit heat-reflective shields, and clean filters and coils monthly since dust builds up fast under direct sun exposure.
