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.

- 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 Shuwaidi is a modern residential district in north Jeddah, known for high-quality villas and tall apartment blocks on spacious plots between buildings. The open spaces allow better placement of outdoor units, but the large villas and contemporary architecture call for a sophisticated AC system handling multiple zones. Design here focuses on precise heat load calculation for each room, especially large lounges and home offices, and routing ducts through high ceilings and modern walls.
Al Shuwaidi is in north Jeddah, an upmarket residential district with high-quality villas and modern apartment blocks on spacious plots.
Villas and apartment blocks in Al Shuwaidi typically need advanced central AC systems with multi-zone controls to cover large areas and multiple storeys.
The AC setup in Al Shuwaidi
- 1
Powerful central system with zone control
Luxury villas and large blocks in Al Shuwaidi benefit from a powerful central unit with separate plant rooms and zone control balancing cooling across different areas.
- 2
Ducts in walls and suspended ceilings
The design takes advantage of thick walls and modern suspended ceilings to run ducts easily and conceal pipes from view.
- 3
Outdoor units on spacious rooftops
Villas and blocks in Al Shuwaidi offer spacious, open rooftops for easy outdoor unit placement, away from the building's front views.

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 villa in Al Shuwaidi is luxury and very large, how many AC units does it need?
It depends on the number of rooms, levels and total area. We calculate heat load per zone and recommend the unit count, which might be one powerful central unit or several distributed units with zone controls.
The open spaces in my villa are very large, can we achieve even cooling in them?
Yes, through intelligent duct routing with multiple distribution openings in ceilings and walls, and setting air velocities to avoid draughts while maintaining even coverage.
Does the design account for interior rooms with no windows?
Yes, interior rooms have different cooling needs than sun-exposed rooms, and we factor this difference into load calculations and distribution.
Do high ceilings in the villa affect AC efficiency?
Yes, high ceilings need special consideration to avoid energy waste and cold air stratification at the top. We include this in design when sizing units and routing ducts.
