Window unit to split
Window-to-split conversion in Al Shama'il
Window-to-split conversion in Al Shama'il frees you from noise, dust and heat seeping in. We seal the old opening with strong insulation and matching paint, then fit a split through a small protected 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.
Ask on WhatsAppManaging a rental flat and want to raise its value
We convert the flat's window unit to a quiet split and restore the wall and window to their original condition, improving the unit for the next tenant.

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 Shama'il is a growing residential district mixing new villas and mid-rise apartment blocks, where summer's severe dust and heat make old window units a double problem, they do not filter fine dust effectively and leave gaps at the edges. Switching to split reduces dust ingress and improves cooling efficiency, and the modern building stock here allows a safe single core hole without structural risk.
Al Shama'il sits in north-east Jeddah, a modern residential zone of villas and apartment blocks with relatively wide streets.
Most villas and flats in Al Shama'il start with temporary window units before converting to split, due to the upfront conversion cost.

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.
There is a lot of airborne dust here, does split protect better than window units?
Yes, split units have more efficient filters and protected ducts, so they cut dust ingress significantly, especially if you clean the filter every two weeks during dust season.
Our villas are new and well-built, are there any weak points in the walls?
New walls in Al Shama'il are very strong, and the single small core hole for the split has zero impact on the building's strength.
Summer heat here is extreme, can a new split unit cope?
The split unit fitted is reliable and rated for Jeddah's heat, but the outdoor unit needs ventilation, so we position it away from hot walls and direct sun.
New flats and villas have advanced wiring, is the connection safe?
The split is connected to a separate breaker or dedicated circuit, and we check the electrical capacity beforehand to ensure full compatibility and safety.
