Central AC for apartments
Apartment central AC in Harat Al Sham
In Harat Al Sham, at Jeddah's historic heart, installing central AC in apartments works with old buildings, low ceilings and very tight voids. Alrabih plans the design carefully to minimise wall changes and preserve the district's architectural character.

When central AC makes sense in your flat
- 1
New flat before finishing
The finishing stage is the right time to install central AC. The ceiling is open and walls are ready for copper and drain routes, so there is no need later to cut plaster or damage finished surfaces.
- 2
Occupied flat where splits fall short
If splits leave hot and cold patches, or the noise bothers you at night, central AC distributes air evenly and hides the unit away from the room. A site survey decides whether your ceiling height allows it.
- 3
Your unit disturbs the neighbours
In apartments, neighbours hear unit vibration through shared ceilings and walls. We choose the indoor unit suspension point carefully and use flexible collars on the air outlets to absorb vibration before it reaches the building structure.
Who it's for
Living in a furnished flat and want to replace splits
We survey your ceiling void to see whether a concealed unit fits, then run copper and drain without disturbing the existing décor.

We coordinate with the finishing stage to run copper, drain and ducts before ceilings and walls are closed, so every route stays fully concealed.

What the installation covers
- Ceiling survey and unit position
- Mueller copper fully insulated
- Condensate drain with correct fall
- Air ducts and distributed outlets
- Line vacuum and start-up test
How we work
How we work
- 1
Ceiling and route survey
We measure the available ceiling void, decide where the indoor unit hangs, map the copper route and find where condensate drains without causing damp. The survey decides whether one zone or more suits the flat.
- 2
Run copper and drain
We run insulated Mueller copper in the void above the suspended ceiling and slope the condensate line towards the building drain or an external outlet, so no standing water causes odour or damp.
- 3
Fit ducts and outlets
We mount the indoor unit on vibration-absorbing hangers, route ducts to each room and place every outlet so air spreads evenly without blowing cold air directly onto anyone.
- 4
Vacuum, test and hand over
We vacuum the copper line to remove air and moisture, check all joints, then run the unit and confirm cooling in every room before we hand over.
A considered install or a hasty one?
| Alrabih | The usual way | |
|---|---|---|
| Indoor unit position | Set after measuring the void | Wherever it fits |
| Condensate drain | Calculated fall to building drain | May pool and cause damp |
| Vibration | Absorbing hangers, flexible collars | Reaches the neighbours |
| Air distribution | Outlets placed for even spread | Cold rooms and warm rooms |
| Salty sea air | Mueller copper, tight flared joints | Early joint corrosion |

What sets this district apart
Harat Al Sham is a very old district with mainly historic buildings, where flats are small, ceilings are low and the voids between walls and ceiling are extremely tight. Central system installation here faces real challenges because old structures may not tolerate easy breakage, and old wiring may occupy the limited available space. The solution requires highly customised design, possibly including very flexible ducts or even non-standard units, and every change must be carefully planned to avoid wall damage or roof leaks.
Harat Al Sham is a very old historic district in Jeddah's downtown, its buildings are mainly old structures with traditionally low roofs.
Ceilings here are very low and the voids above are so tight that most flats need wall-mounted units rather than overhead ducts.
The AC setup in Harat Al Sham
- 1
Wall-mounted units instead of ceiling routes
In most old flats, indoor units are wall-mounted on external walls to avoid further lowering an already low ceiling.
- 2
Highly flexible first-grade ducts
Ducts are highly flexible and narrow, avoiding old structures and existing wiring while fitting extremely tight roof voids.
- 3
Staged distribution or small split units
Some flats may take two small separate units instead of one central unit to minimise the void needed and construction changes.
Before the visit
Before our visit in Harat Al Sham
- 1
Bring an old plan or photos of the building structure
If you have an old building plan or photographs of the structure, bring them to help us understand the original design and materials.
- 2
Check walls and ceiling for cracks or damp
Tell us about any existing cracks or damp patches before the visit so we can avoid worsening them during installation.

Identify possible outdoor unit and drain locations
Note whether there is a safe balcony or roof for the outdoor unit, and identify the best route for condensate to drain outside.

FAQ
Questions about Apartment central AC
Is there enough ceiling space in a flat for a central unit?
It varies between flats. Slim ceiling cassettes need less void depth than full ducted units. A site survey measures what is available and decides the right type; if the corridor ceiling is too shallow we look at a storage room or bathroom ceiling instead.
Is one unit enough for the whole flat or do I need more?
It depends on the flat's area, room layout and how much sun each side receives. Two- and three-bedroom flats can sometimes work with one unit and well-planned ducts; larger flats or those with separate zones may need two. The survey decides.
Where does the outdoor unit go when the flat has no large balcony?
Options include the shared roof if the building rules allow it, a facade bracket away from neighbours' windows, or the balcony if it can take the load. We review the building's rules before recommending any position.
Jeddah's air is very humid; does that affect the condensate drain?
Yes. In Jeddah the indoor unit produces more condensate because of the high humidity. We make sure the drain line has enough fall, that the horizontal run before it drops is not too long, and that the outlet does not conflict with other flats' drainage in the building.
Can the flat be split into two zones with different temperatures?
It is possible using two separate indoor units or by adding variable-flow dampers on the duct runs. The right choice depends on the flat's layout and the ceiling void available in each zone. A site survey decides which approach suits your room arrangement.
Our ceiling is very low, can you install central AC at all?
Yes, but we may need to use wall-mounted units or very flexible ducts instead of traditional overhead routes.
The building is very old, are you concerned about water leaks from the roof?
Yes, we choose routes and drainage that minimise holes in roof and walls, and seal any penetration point to prevent leaks.
The flat is full of old wires and pipes, is there space for new ducts?
We carefully survey the current layout and design ducts that avoid existing wiring and pipes, or we may propose relocating some old equipment if safe.
Our walls may be mud brick or old stone, can you drill into them safely?
Yes, we use tools suited to old walls, but we may need a pre-installation survey to ensure the wall is sound and no existing cracks could worsen.
