Design before you buy
HVAC design in Muraykh
HVAC design in Muraykh begins with precise heat-load calculation for each space based on its size, windows and sun exposure. We select the right system and draw the layouts before you buy 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.

| Alrabih | The usual way | |
|---|---|---|
| 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
Muraykh is a growing residential district in east Jeddah with villas of varying sizes and relatively modern flats built to current standards. The buildings here mix large and medium villas with residential flats, meaning cooling requirements vary significantly from unit to unit. Precise heat-load calculation is essential because a large villa may need a completely different system than the small flat next to it.
Muraykh is in east Jeddah, a growing residential district with villas of varying sizes and modern flats in close proximity.
Adjacent villas and flats in Muraykh require separate heat-load calculations because each unit's cooling needs differ significantly from its neighbours.
The AC setup in Muraykh
- 1
Independent split for each section of large villas
Large villas in Muraykh typically benefit from one or more outdoor units with several independent indoor units for each zone.
- 2
Central ducted system for villas with ceiling space
If the villa has adequate ceiling space, a unified duct system can be designed for balanced distribution to all rooms from one or two outdoor units.
- 3
Flexible expandable systems for future additions
Some villas may need expansion later, so we design with reserve capacity or allow for a future additional outdoor unit.
Before the visit
Before our visit in Muraykh
- 1
Provide an accurate plan showing all rooms and openings
We need a detailed plan showing each room's dimensions and all windows, doors and corridors, so we can accurately calculate load for each area.
- 2
Pre-identify all intended outdoor-unit locations
Tell us the proposed locations for outdoor units, roof, ground or wall, so we can calculate line lengths and distances accurately.
- 3
Complete the structural and ceiling work before the visit
Ensure concrete structure, ceilings, floors and openings are finished before the visit, so we can assess actual spaces and available options.

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 sits next to a small flat, does the design differ between us?
Yes, the cooling needs for a large villa are completely different from a small flat. We calculate the heat load for each unit separately based on its size, windows and occupancy.
How do you handle large villas needing complex systems?
For large villas, we calculate the load for each section separately and choose between central ducted systems or multi-head splits distributed across multiple outdoor units.
My villa has rooms with different sun exposure, how does this affect the design?
Different sun exposure increases heat load in some rooms. We calculate the load for each room based on its sun orientation and may choose separate splits for high-exposure rooms.
Can the design be modified later if I add a new room?
Yes, we design the system flexibly to allow adding indoor units later, though this depends on whether the current outdoor unit can handle the expansion.
