Window unit to split
Window-to-split conversion in Al Dahiyah
In Al Dahiyah, south Jeddah, where spacious villas and modern blocks stand, many owners seek to replace old window ACs with silent, modern splits. Alrabih's team removes the window completely, seals the opening with blockwork, insulation and paint, then installs the split through a new small 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
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 Dahiyah is a modern residential area with spacious villas and mid-rise blocks spread across wide streets and green spaces, yet older units still have large window ACs that fully block windows and consume significant external wall space. Replacing a window with a split requires precise wall engineering and robust insulation to shield from fierce southern heat, and Al Dahiyah's open spaces and wide roads provide easy and safe team access.
Al Dahiyah sits in south Jeddah, a modern residential area with spacious villas, spaced blocks, green spaces and wide streets.
Most villas and blocks in Al Dahiyah have strong standard external walls allowing safe opening and secure sealing of new split pipes.
The AC setup in Al Dahiyah
- 1
Modern split with capacity suited to full room space
The old window blocks an entire window in the external wall, so we select the new split with high capacity to cool the full space efficiently.
- 2
Tight seal with thermal insulation and moisture barrier
The old window opening is filled with blockwork and thermal insulation of standard thickness, with a moisture barrier layer before plaster and paint.
- 3
Split pipes through a safe independent core opening
Cooling and drainage pipes pass through a safe independent opening with secure sealing, preserving frame strength and fully restoring window use.

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.
Al Dahiyah has lots of green spaces, does that affect the new split installation?
Green spaces provide good airflow for the split's outdoor unit, improving efficiency, and make team access easier without obstacles.
How long does it take to seal the old window and install the new split?
Time depends on wall condition and opening size. Send a site photo on WhatsApp, and we will confirm a precise visit time after assessing.
Does the new seal reduce dust and moisture ingress from outside?
Yes, the tight seal with thermal and moisture-resistant insulation significantly reduces dust and humidity ingress compared to an old deteriorating window unit.
After window removal, will it be sealed shut or can it open for natural air?
The window after AC removal returns fully to its original state, you can open and close it freely for natural air and light, while the split runs independently.
