Window unit to split
Window-to-split conversion in Prince Abdulmajeed
In Prince Abdulmajeed, south Jeddah, converting a window unit to a split gets your window back and eliminates the noise and heat leakage. Alrabih closes the old opening with blockwork, insulation and paint, then installs a new split through its own discrete core hole.

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

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
Prince Abdulmajeed holds newer villas and flats with wider outdoor spaces than central Jeddah, yet many older residents fitted window units in main rooms before splits became standard. Converting here means sealing a large opening in an exterior wall exposed to heat, coastal humidity and dust, then fitting a new split with a relatively short copper run to an outdoor unit on the roof or balcony. The conversion improves the room's thermal insulation and eliminates noise and vibration.
Prince Abdulmajeed lies in south Jeddah, a district of relatively modern villas and residential apartment blocks with adequate outdoor space.
Most villas and flats here have roofs or balconies large enough to mount the new outdoor unit well out of sight.
The AC setup in Prince Abdulmajeed
- 1
Sealing the large window opening with blockwork
We fill the window opening with blockwork, cement, thermal insulation and exterior and interior paint suitable for coastal climate and sun exposure.
- 2
Separate small hole for copper tubes and drainage
After sealing, we drill a small hole around 5 cm through the exterior wall for the copper and drainage line, with insulation round the opening.
- 3
Outdoor unit mounted on roof or balcony
Most villas and flats here have a roof or balcony large enough to house the outdoor unit out of direct street view.

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.
Does converting to a split after sealing the window involve extensive building work?
Yes, we seal the old opening with blockwork, cement, thermal insulation and paint, then drill just a small hole for the copper tubes and drainage. The work is contained and we clear up after ourselves.
Our villa's outer wall faces sun and coastal humidity, does that affect the sealing?
Yes, walls facing sun and coastal air need strong thermal insulation and protective paint. We use materials rated for coastal climates to keep the seal durable.
Where on my villa's roof will the new outdoor unit sit?
We choose a roof spot out of view from the street or courtyard, ensuring good airflow around it. We agree the placement with you before starting.
Will the copper pipes from the new unit require a long run down to the room?
Not typically, since villas and flats usually have the roof close to the room, so we usually need just a short run, which we insulate well to minimise heat loss.
