Window unit to split
Window-to-split conversion in Al Quraini'yah
In Al Quraini'yah, south Jeddah, converting from a window unit to a split reclaims your narrow windows and opens natural ventilation in the dense residential area. The opening closes securely with effective insulation, and the split delivers better cooling than the old window unit.

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 Quraini'yah is a densely built residential district with mid-rise blocks and flats with narrow windows, limiting natural ventilation. Window AC units clog these small openings and increase the sense of stuffiness and heat because so little natural air enters. Converting to a split restores the narrow window fully and improves natural airflow throughout the flat, boosting overall comfort. Buildings here have solid construction and tolerate the simple structural changes needed.
Al Quraini'yah sits in south Jeddah, a densely built residential district with narrow windows and limited natural ventilation.
Most flats here have small, narrow windows, and converting from a window unit to a split requires precision in closure to avoid wall damage and to keep the remaining window functional.

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.
Our window is very narrow, will converting to a split improve natural ventilation?
Yes, removing the window unit restores the full narrow window for natural air entry, improving ventilation rather than relying on the AC alone.
Our walls are relatively thin, will the closure be structurally safe?
We check wall thickness and structure first, then use lightweight masonry and insulation that don't stress the wall.
Humidity is high in our area, how will the closure handle moisture?
We choose moisture-resistant insulation and create safe drainage gaps behind the new wall, with external finish paint that resists water seepage.
Where will the outdoor unit fit in our densely built area?
We choose the external wall or small balcony for the outdoor unit, and if unavailable we explore safe shared roofs or common walls with coordination from neighbours and building management.
