Central AC installation in Al Mahjar

We calculate the thermal load for each zone based on its area, ceiling height, number of external openings, orientation and how it will be used. In Jeddah the sun's effect on west-facing facades is significant, and high humidity goes into the calculation. We choose the unit size after this calculation, not before.

We fabricate round and rectangular ducts in our own workshop from G90 galvanised sheet or aluminium sheet depending on what the project needs. This lets us cut ducts to the exact site dimensions and fit them tightly, avoiding ill-fitting sections that leak air and raise electricity consumption.

We use Mueller copper in runs of up to 30 metres without welded joints, which reduces potential leak points. If a run exceeds that, the survey determines whether the outdoor unit position needs rethinking or whether the refrigerant charge needs adjustment according to the type shown on the unit's nameplate.

Yes, and it is settled at the design stage. Each floor can have its own unit, or the network can be split into zones with dampers and a thermostat in each, so you do not cool the whole upper floor while the family sits in the majlis. We recommend the right option after the load calculation.

Yes, and the roof surface determines what kind of base is needed. For villas we fabricate a raised steel frame that keeps the unit clear of pooled rainwater and allows airflow beneath it. The exact height and angle depend on the roof pitch and the condensate drain position, which the site survey establishes. The aim is to keep the unit level and to prevent vibration movement during operation.

We calculate the thermal load based on your villa's floor area, number of storeys, windows and doors, and insulation. You might need one powerful unit or two separate ones. We give you a precise recommendation after the first visit.

Quite the opposite; Al Mahjar's wide streets make it easy for our equipment and workshop van to access the site. We plan the copper runs and ducts in advance, so just ensure there is safe pedestrian access from the road to the outdoor plot.

Yes, southern Jeddah records high temperatures especially in summer, and we account for that. Direct sun exposure on the villa's outer walls and roof also increases the load, so we check window orientation carefully during the first visit.

If the floor is newly laid, cutting it later is difficult, so duct routing must be planned before we start. In the first visit we examine the floor, ceiling and internal layout to choose the best duct path without harming the structure.
