Window unit to split
Window-to-split conversion in Al Mahamid
In Al Mahamid, east Jeddah, many villas and residential blocks still have old window units blocking natural light and letting in heat and dust. Alrabih closes the window opening with blockwork, insulation and paint, then fits a new split with its own small core hole, so you recover the window's light and peace.

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 Mahamid is a mixed residential area with medium villas and residential blocks of three to six storeys, many built in earlier decades before split units became standard. The old window unit takes up a large part of the window, and the wish to recover natural light and fresh air is a strong driver for conversion. The work requires coordination with the building or villa management to schedule the job around occupied flats, especially in multi-family blocks.
Al Mahamid is in east Jeddah, a balanced residential district mixing medium villas and mid-rise apartment blocks with open streets and older architectural depth.
Many villas and flats in Al Mahamid still have their original window units, and conversion to split requires safe closing of the opening and precise window restoration.
The AC setup in Al Mahamid
- 1
New small window opening for the core
The new split requires a small, precise opening in the window frame to pass the copper pipes through, replacing the large old window unit opening.
- 2
Complete closure and repainting of the original window
After removing the unit, we fill the opening with blockwork and insulation, then repaint the window to match the villa or building facade.
- 3
Outdoor unit on the villa facade or balcony
The outdoor unit is mounted on a safe villa facade or balcony, positioned away from direct heat and dust sources where possible.

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.
When I remove the window unit, does the opening leave a dangerous gap?
No, we close the opening completely with blockwork, insulation, filler and paint, making it a safe and permanent part of the wall and window frame.
Do I need approval from the building management before conversion?
Yes, approval from the building or villa management is needed before we start, especially if there are any architectural rules about the building's external facade.
Al Mahamid gets intense heat and dust, will the new split unit provide enough protection?
The split unit significantly reduces heat and dust entry compared to the window unit, because the outdoor core is small and tightly sealed, and we clean it regularly as part of maintenance schedules.
My building has old wiring, does conversion require upgrading the electrical circuit?
It depends on the state of your current electrical connection, and our team inspects the circuit during the visit and recommends any upgrades needed before fitting the new split.
