Design before you buy
HVAC design in Al Sawari
In Al Sawari, north Jeddah, HVAC design must precede any purchase to ensure even cooling across the modern villas and apartment blocks. Alrabih calculates the heat load for each space and selects the right system before any equipment investment.
- Accurate heat loads
- System selection
- Duct drawings

Who needs a considered design?
- 1
Owner planning a new build
Before walls and ceilings are finished you still have the chance to route ducts and place units correctly. Early design prevents costly surprises during fit-out and delivers rooms that cool evenly from the first day of operation.
- 2
Architect or contractor needing drawings
The project needs mechanical drawings to co-ordinate with the structure, electrical and plumbing trades. We produce duct layout drawings, equipment positions and installation heights in a format the site can use directly.
- 3
Existing building with uneven cooling
Some rooms stay hot even with the AC running while others are over-cooled. The cause is usually wrong airflow distribution or uncalculated capacity. A redesign finds the fault and defines what needs changing before any new purchase.
Who it's for
Building a villa and want design before fit-out
We calculate the heat load for every room in the villa and draw duct routes before ceilings are closed, so you avoid breaking the finished work later.
Ask on WhatsAppRunning a commercial building with hot rooms
We review the current airflow distribution and recalculate loads per space, then identify faults in the ducts or equipment and draw the required changes before any purchase.

What the design covers
- Heat load per room
- Right system type selected
- Equipment from authorised brands
- Duct distribution layout drawings
- Equipment schedule for construction
How we work
How we work
- 1
Gather building data
We ask for the architectural drawings or visit the site to measure spaces and record glazing, orientation and internal loads from people, equipment and kitchens.
- 2
Calculate heat loads
We calculate the heat load for each space separately, accounting for Jeddah's intense sun, high humidity and exposed facades, so every unit is sized on real load not guesswork.
- 3
Select system and equipment
Based on loads and building type we choose between splits, ducted systems, central air and chiller, and specify equipment from Carrier, YORK, General, Midea, Gree and Smart Gold to suit the project.
- 4
Draw and deliver
We draw duct routes, unit positions, diffuser locations and installation heights, and deliver a complete equipment schedule ready for construction or tendering.

What sets this district apart
Al Sawari holds modern, well-spaced villas and mid-rise residential blocks in orderly urban layout with wide streets. This building pattern offers flexibility in system choice, either independent splits per flat or central AC for larger villas, but the heat load varies by building aspect and glazing. Precise design determines unit count, capacity and ductwork before construction or modification.
Al Sawari lies in north Jeddah, a modern urban zone of villas and residential blocks in planned layout.
Villas and apartment blocks here rely equally on split systems and central AC, depending on building size and budget.
The AC setup in Al Sawari
- 1
Central AC for larger villas
Large Al Sawari villas benefit from a unified central system that delivers even distribution and single control across all rooms.
- 2
Separate split units per residential unit
Flats and small villas in apartment blocks need independent split units for easier maintenance and individual control per unit.
- 3
Hidden ductwork in dropped ceilings
Ductwork typically runs through dropped ceilings or architectural voids to preserve the villa or flat's aesthetic appeal.
Before the visit
Before our visit in Al Sawari

Measure rooms and glazed windows
Ensure you measure length, width and height of each room accurately, note the number and size of windows and solar direction before our visit.
- 2
Mark available outdoor unit locations
Mark possible spots on the roof or exterior walls for outdoor units, ensuring they do not block neighbours' views.
- 3
Confirm electrical supply and circuit access
Check that separate electrical circuits with adequate capacity are available for the AC system, and locate the distribution board before the design visit.

FAQ
Questions about HVAC design
When is a chiller more suitable than split units?
The decision depends on the building area, number of spaces and how it is used. In large commercial and hotel buildings a chiller gives flexible control and simplifies central maintenance. In apartments and smaller villas a split or ducted system usually fits better. The calculated heat load is what determines the right choice for your building.
How does a large glazed facade affect the design?
Large glazing exposed to Jeddah's sun raises the heat load noticeably, especially on west and north-west facades. We calculate solar gain through each facade separately, and this can change the unit type selected for that room or require extra diffusers to handle the higher load.
Can you design for an existing building with no architectural drawings?
Yes. When no drawings exist we visit the site and measure every space ourselves, recording facades, glazing and how each room is used. The survey takes longer than reviewing ready drawings, but the calculations still rest on real measurements rather than estimates, which is what makes the results reliable.
Does the design include diffuser types and dampers?
The drawings specify diffuser types, positions and sizes to match ceiling height and room shape, and show where dampers are needed to balance airflow to each zone. These details matter because a diffuser in the wrong place wastes a large part of the system capacity even when the units are correctly sized.
Does duct design differ between the ground floor and upper floors?
Yes. The top floor typically carries a higher heat load because the roof is directly exposed to the sun, which affects duct sizes and the number of diffusers needed on that level. We design each floor separately based on its own calculated load and show where dampers are needed to balance airflow between floors.
My modern villa in Al Sawari is large, should I choose central AC or multiple units?
We calculate the heat load for each room, the villa's size and solar exposure, then advise you on the best-fit system and its actual cost before you buy.
My flat in a new Al Sawari building, how do we design its air conditioning?
We visit the flat, measure rooms and windows, calculate the load accounting for east or west exposure, then draw the unit locations and duct runs.
Al Sawari gets intense summer heat, does that affect the unit size we need?
Yes, the heat load rises with summer temperatures and large windows, so we increase AC capacity to ensure even distribution and steady comfort.
The ductwork and pipes need wall space, how do we route them?
We draw the ductwork before you buy so it runs through dropped ceilings, roof space or behind walls safely and efficiently, without reducing usable floor area.
