Window unit to split
Window-to-split conversion in Al Gharbiyah
In Al Gharbiyah, north Jeddah, newer villas and residential blocks need to replace old window units with modern split systems. We seal the window opening with blockwork, plaster, insulation and paint, then install a new split in its own core hole, so you get your window, light and quiet back together.

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 Gharbiyah is a relatively modern, spacious district with detached villas and spaced-out residential blocks on regular streets, but many owners fitted window units years ago as the cheaper option. Now they want to lose the noise and the large opening that lets in Jeddah's heat and dust, especially as old foam shrinks and lets unconditioned air in. The conversion here is simpler than in dense districts, because there is space and easy access to windows and external walls.
Al Gharbiyah lies in north Jeddah, a relatively modern, spacious district of villas and spaced-out residential blocks.
Most newer buildings here have regular facades and standard electrical runs, making window-opening repairs and routing new split pipes a straightforward process.

New split with dedicated core hole through the flat or villa wall
After sealing the window opening, we drill a new small core hole at the required diameter for the split pipes and cables, separate from the sealed opening.

We reapply plaster, insulation and paint to the exterior and interior wall to ensure a clean finish that blends with the surroundings.

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 window has been blocked by a unit for years, is it safe to seal the opening?
Yes, we seal the opening with blockwork, plaster, insulation and paint to modern standards. The external walls in Al Gharbiyah are usually strong enough to take the repair without structural issues.
Where will you mount the new split's outdoor unit?
Usually on the external facade, villa roof or back balcony, depending on the location and available space. We agree the best spot before starting to avoid conflict with neighbours or aesthetics.
Al Gharbiyah gets very hot in summer, will the new split cool better than the window unit?
Yes, a modern split is far more efficient than old window units, particularly because there is no large opening letting hot air in from outside. The new unit will isolate the room much better.
My villa's electrician may ask about the new unit's power supply, does it need its own circuit?
Usually yes, depending on the split's capacity. Best practice is to run a separate circuit from the villa's main board. We consult the local electrician at installation to ensure it matches the existing electrical network.
