Design before you buy
HVAC design in Al Fardous
HVAC design in Al Fardous begins by measuring the actual heat load for each room, not guesswork. We calculate cooling needs based on space size, natural light and expected occupancy before selecting any equipment.
- 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 Fardous is a modern residential district with multi-storey apartment blocks and medium-sized villas with varied architectural spaces. Buildings here are reasonably well designed but many owners choose equipment without prior planning, leading to uneven cooling and high electricity bills. Proper design accounts for building orientation, glazed windows and floor level, upper or ground.
Al Fardous sits in north Jeddah, a mixed district of apartment blocks and medium villas with moderate space sizes.
Al Fardous flats and houses need split or semi-central system design with compact ducts for efficient air distribution between rooms.
The AC setup in Al Fardous
- 1
Independent split unit per flat
Most Al Fardous flats use one or two split units depending on flat size and architectural design.
- 2
Semi-central system with compact ducts
Some larger Al Fardous flats prefer compact air ducts distributing coolness from a single outdoor unit.
- 3
System with zone control
The design may include duct dampers for separate control between bedrooms and living areas if the flat needs it.

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 flat is on the top floor, is the design different from lower floors?
Yes, top floors are exposed to the roof's heat directly, so we increase the appropriately sized unit and calculate the heat load higher.
How do the number of windows in my flat affect the AC choice?
Glazed windows let in significant solar heat, especially if they face south or west. We factor this into the heat load to select the correctly sized unit.
My flat has an open plan, how do you distribute the cool air?
An open plan needs a single outdoor unit with compact ducts or a single split, and we place the air outlet to distribute coolness evenly.
What is the difference between design and installation? Can I choose the equipment myself?
Design specifies the system type and unit sizes and ducts before purchase. Choosing equipment without design may lead to oversized or undersized units and energy waste.
