Design before you buy
HVAC design in Al Abeer
HVAC design in Al Abeer starts with calculating the heat load for each room based on its area, glazing and sun exposure. We select the right system type and draw the layouts before you buy any equipment, avoiding oversized units and uneven cooling.
- 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 Abeer is a modern residential district of spacious villas on large plots and contemporary multi-storey flats, with varied architectural designs and large glass facades that increase sun exposure. This variety requires precise design of central systems and multiple split units, since each villa or flat has different cooling needs based on sun direction, open spaces and the thermal insulation of walls and ceilings.
Al Abeer lies in north Jeddah and contains diverse modern residential buildings ranging from spacious villas to contemporary apartment blocks.
Villas in Al Abeer typically need a central system with air distribution through ducts in ceilings or external walls.
The AC setup in Al Abeer
- 1
Central system with concealed air ducts
Modern villas in Al Abeer often allow ducts to run through suspended ceilings or walls, ensuring even cold air distribution throughout all rooms.
- 2
Multiple splits with a single outdoor unit
Some apartment blocks use a multi-split system connecting all indoor units to a single multi-zone outdoor unit, saving space and improving efficiency.
- 3
Separate split units per floor
Large multi-storey villas may need separate split units per floor or wing to allow independent control of cooling and comfort in each area.
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.
My villa has large glass facades, how much cooling capacity do I need?
Large glazing significantly increases the heat load, especially on south and west faces. We calculate this precisely during design to select the right capacity and number of outlets.
Should I install a central system or multiple split units?
It depends on the building's size and layout. Central systems work better for large unified villas, while multiple splits suit flats and villas with separate wings.
Summer in Jeddah is extremely hot, does HVAC design differ here?
Yes, we raise the heat load calculation for south and west-facing designs, select equipment with higher capacities and recommend additional thermal insulation for roofs and external walls.
Where should the outdoor unit sit in a villa, and how long should the copper run be?
The outdoor unit's location depends on the villa's design and available space on the facade or rear garden. The copper run length affects efficiency, and we recommend keeping it under 15 metres where possible.
