Window unit to split
Window-to-split conversion in Al Muhammadiyah
In Al Muhammadiyah, north Jeddah, villas and flats need old window units replaced with splits. Alrabih closes the opening with insulation and paint, fits a new split, and the window and room regain light and quiet.

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 Muhammadiyah is a mixed area of modern villas and apartment blocks with medium-sized spaces and regular streets, though many homes have not been updated. Many windows are blocked by old AC units, and removing them restores natural light and air to living and sleeping areas. Professional closure protects against coastal humidity and accumulated dust around the buildings, and the new split delivers quieter, more efficient cooling in the hot, humid climate.
Al Muhammadiyah sits in north Jeddah, a mixed residential area of modern villas and blocks with regularly spaced medium-sized plots.
Most villas and blocks here have modern-standard windows, but many flats had window units added later, so conversion becomes necessary after years.
The AC setup in Al Muhammadiyah
- 1
Secure closure with moisture and mould-resistant insulation
The opening is sealed with moisture-resistant materials and mould-resistant paint for long-term protection in a humid coastal climate.
- 2
Split system with separate indoor and outdoor units
The indoor unit sits beside the closed opening, and the outdoor unit connects via a slim horizontal hole on the exterior wall.
- 3
Restoration of natural light and air flow to the room
Once done, the window reopens fully, and natural light and fresh air return to the room.

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.
The window unit has been there for years, is the wall underneath intact?
We inspect the wall carefully before closure, and if there is prior damage, we repair it before closing and painting.
Will closing the opening affect the room's future insulation?
No, a solid wall with good insulation performs better than the old window, and future cooling needs will be lower.
Coastal humidity is high here in winter, does closure provide protection?
We fit moisture-resistant insulation and apply mould-resistant paint, protecting against seepage and mould long-term.
After conversion, will the split be more efficient than the old window unit?
Much more so, window units lose cool air through cracks and frames, but modern splits deliver consistent cooling with higher efficiency.
