Window unit to split
Window-to-split conversion in Al Wisami
In Al Wisami, north-east Jeddah, converting a window unit to split requires a team that seals the opening carefully and fits the new unit in a separate core. Alrabih returns your window to light and fresh air without noise or heat loss.

Why owners make the switch
- 1
Non-stop noise from the old unit
The window unit motor runs right inside the room, and the vibration gets worse over the years. Many owners say sleeping next to it has become impossible, and switching to a split removes the source entirely.
- 2
The wall opening lets in heat and dust
The foam and tape sealing the gap around a window unit frame degrade in Jeddah's salty, humid air. The large opening becomes a clear source of heat loss, dust in the windy season and sometimes rain in winter.
- 3
The blocked window darkens the room
A window unit fills the whole window or most of it, so the room loses its natural light and ventilation at times when you do not need cooling. Getting the window back fully changes the room noticeably.
Who it's for
Own a villa and want the windows back
We remove the window units from your villa rooms, close each opening with block, insulation and plaster, then fit a split in each room through its own core hole.

How we work
How we work
- 1
Survey the wall and opening
We check the wall thickness and the build around the old opening, agree where the new core hole for the split goes away from the old frame, and decide where the outdoor unit will sit.
- 2
Remove and close
We remove the window unit and its frame without breaking the surrounding wall, then close the opening with blockwork or lightweight concrete to match the original construction, with thermal insulation set inside the layers before plastering.
- 3
Plaster and paint both sides
We plaster and paint the closed opening on both the inside and outside faces to match the existing wall, leaving no trace of the old opening that could let in air or moisture.
- 4
Fit the new split
We core the agreed spot for the split, run insulated Mueller copper and a drain line with the correct fall, vacuum the line before start-up and test everything with you present.

What sets this district apart
Al Wisami has relatively modern apartment blocks and villas with wider outdoor space than older districts, though many residents still own old window units in bedrooms. Converting to split here means sealing a large opening properly with good insulation, since the walls may be thick concrete slabs needing precise drilling for the pipes. The new outdoor unit can use the available space around the villa or block.
Al Wisami is in north-east Jeddah, a district of relatively modern residential blocks and extended villas with open surrounding land.
The villas and blocks here allow mounting the outdoor unit on a separate external wall or the courtyard roof, making it easier to run the pipes and wiring.
The AC setup in Al Wisami
- 1
Full closure of the window opening and rebuilding
The opening is filled with blockwork, mortar and thermal insulation, then the wall is repainted. This restores the wall almost to its original condition.
- 2
Separate new hole for pipes and wiring
We drill a small precise hole nearby to run the gas, water and electrical lines to the outdoor unit without damaging the window frame.
- 3
Secure mounting of the outdoor unit in the garden or on roof
The outdoor unit is mounted on the courtyard roof or external wall with strong metal brackets, with ample clearance for airflow and drainage.
Before the visit

Tell us your preferred outdoor unit location
Let us know if you prefer mounting on the courtyard or on an external wall, since this affects the pipe run and the quote.
- 2
Ensure the window and yard are accessible
Verify that the team can safely access the window to be closed and the proposed outdoor location without obstacles.
- 3
Prepare the wall for drilling and blockwork
Check that the wall is clear of hanging items or hidden wiring near the new opening location to prevent damage.

FAQ
Questions about Window-to-split conversion
Do you restore the original window after closing the AC opening?
It depends on what the original opening was. In some rooms the opening was cut into a solid wall with no window frame, so it is fully closed. If the original build can take a window, we discuss that at the survey and tell you what is actually possible in your wall.
Can the old window unit hole be reused as the new split core hole?
The old opening is usually much larger than the small core a split needs, and its position may not suit the copper and drain route. It is safer to close it fully and drill a new hole in the right place, so no hidden gaps remain to let air through or collect moisture.
How do you stop humid salty air coming through the closed opening?
We place thermal insulation inside the wall layers before plastering, and use sealing materials that form a continuous barrier from inside to outside. Jeddah's combination of humidity and salt accelerates the breakdown of any temporary patch, so we treat the closed opening as a new wall section, not a surface repair.
Do I need permission from the building management before closing the opening?
In a rented flat it is wise to check with the owner or management office first, because the work changes the building's outside face. In a villa you own the decision is yours. We explain the full scope at the survey so you can get any approval needed before the work day.
Does the job change if the wall is concrete rather than block?
Yes. A concrete wall needs a different filling method and may require a repair mix rather than standard block. We identify the wall type at the survey and choose the material that bonds solidly with the existing concrete, leaving no hidden gaps for moisture to enter later.
The buildings here are newer, does window-to-split conversion require deep drilling?
Modern walls may have thick concrete slabs, so we use specialist drilling equipment to make the pipe opening precisely without weakening the structure. The drilling depth depends on where the outdoor unit will sit.
Can the outdoor unit be mounted on the courtyard roof here?
Yes, many villas and blocks in Al Wisami have courtyard roofs or open land that allows safe mounting with adequate clearance for drainage and airflow.
I have north and south walls, which is better for the outdoor unit after conversion?
A north-facing or shaded wall is better to reduce extra heat absorption if available, but it depends on airflow and mounting feasibility. A site visit clarifies the optimal choice.
How long do the pipes and wiring run between the outdoor and indoor units?
It depends on where you place the outdoor unit and which room you are cooling. We run the pipes through the new wall opening, the length varies by location, and longer runs may need extra insulation.
