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.

- 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.

| Unit size | Based on actual load | Guessed or oversized |
| Airflow distribution | Drawing that achieves even flow | Diffusers placed at random |
| Co-ordination | Drawings before fit-out | Costly changes later |
| System type | Suited to building and budget | Whatever the shop suggests |
| Humidity and salt air | Accounted for in equipment choice | Discovered after installation |

What sets this district apart
Al Nuzlah Al Sharqiyah in south Jeddah features modern villas and luxury apartments on spacious plots with gardens and separate parking. Buildings here enjoy good natural ventilation and varied sun exposure depending on each villa's orientation. Precise design accounting for different exposure on each villa side selects a system delivering high comfort with energy efficiency through the long, hot summer.
Al Nuzlah Al Sharqiyah lies in south Jeddah, a modern residential area of spacious villas and luxury apartments.
Most villas in Al Nuzlah Al Sharqiyah need central or multi-split systems because of large floor areas and high ceilings.

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 faces sun on multiple sides, how does this affect unit selection?
Multiple sun exposures significantly increase total heat load. Design calculates load per side separately and selects units with sufficient capacity to handle heat from all directions.
My villa in Al Nuzlah has gardens and trees, does this reduce heat load?
Yes, trees and natural shade reduce direct sun and heat. We factor this into design but keep sufficient capacity because trees may be removed or change over time.
Is central AC better than multi-split for a villa this size?
Both are valid options depending on villa layout and budget. Design evaluates both, presenting pros and cons of each so you choose.
I want each room at a different temperature, which system allows this?
Central systems with zone control allow this, as does multi-split where each indoor unit has a separate thermostat. Design recommends the best system for your needs.
