Window unit to split
Window-to-split conversion in Al Aziziyah
In Al Aziziyah, central Jeddah, medium-sized flats and villas benefit from replacing old window units with modern split systems for better cooling and comfort. We seal the window opening with blockwork and insulation, then install the new split through a small dedicated 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
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 Aziziyah mixes medium-sized villas and residential flats, many built thirty years ago or more with original window units. The district is gradually developing and owners seek modern alternatives to reclaim window space, cut noise and stop leakage. Replacing the window with a split improves energy efficiency and gives better temperature control through Jeddah's hot summers.
Al Aziziyah sits in central Jeddah, a mixed residential area of medium-age villas and flats.
Outdoor units here are usually placed on side balconies or rear walls, because the district's gradual expansion leaves varying wall layouts.

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.
My flat is small and the window unit blocks light, will conversion open it up?
Yes, removing the old window and heavy unit opens the full window, increasing natural light and your view outside.
Can you fit the split on an interior wall rather than external?
The split needs an outdoor unit in open air, but the indoor unit can be mounted on any suitable interior wall away from the original window.
The sun hits this window all day, will the heat affect the pipe opening?
We use high-grade thermal insulation around the new opening, and the pipes are also insulated to prevent cooling loss and reduce heat absorption from outside.
How long does the window-to-split conversion take?
Duration depends on the wall condition and finishing required, and we confirm the estimated schedule with you on visit day.
