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 Furusiyah is a developed residential area mixing spacious villas, modern apartment blocks and mixed commercial projects. Buildings here benefit from modern planning and proper spacing between units, but variety in building size means each project needs a unique heat load calculation based on area, solar orientation and use, which drives the choice between central and distributed systems.
Al Furusiyah sits in the east, a developed residential district with modern villas and apartment blocks.
Most new projects in Al Furusiyah choose between central AC and advanced distributed systems based on building size and budget.
The AC setup in Al Furusiyah
- 1
Central AC for modern residential blocks
Modern blocks in Al Furusiyah typically use unified central systems with air ducts routed through ceilings or walls.
- 2
High-efficiency distributed splits for villas
Villas in Al Furusiyah use multiple split units with individual control, and many choose smart systems to reduce energy consumption.
- 3
Hybrid system for mixed-use projects
Projects mixing residential and commercial use need hybrid systems combining separate units and central components to meet different thermal needs.
Before the 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.
How do you calculate cooling needs for a villa in Al Furusiyah?
We study the villa's size, number of rooms and windows, and direction of external walls, then account for solar load, humidity and expected occupants, calculating heat load for each section.
Mixed-use project with shops and flats, which system fits best?
Mixed projects need separate or composite systems, perhaps individual units for flats and larger units for shops. We review the plan and recommend the best division.
Does Al Furusiyah's difference from other areas affect the design?
Yes, Al Furusiyah's eastern location and open surroundings mean different solar exposure from central or older districts, so we factor this precisely into load calculation.
If we add another floor later, will the current system be sufficient?
We recommend factoring in likely expansion at the initial design to avoid full redesign later. We suggest a scalable system or advise you to delay additions until we have exact data.
