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

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
Khaleej Salman is a modern villa area with open plots and private gardens, built with large windows facing the street and open views. Many owners installed window AC units years ago, and now want to restore the original light and views. Removing the unit and closing the opening with strong insulation protects against Jeddah's intense heat and coastal humidity, while the new split delivers quiet cooling and high efficiency in the hot, dry climate.
Khaleej Salman sits in north Jeddah, an area of modern residential villas with spacious plots between homes and contemporary window standards.
Most villas here have large windows in living and sleeping areas, so the split fitting requires placing the core hole where it is not visible from the street or front garden.

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.
Does closing the window opening give better insulation than the old window frame?
Yes, a solid wall with thermal insulation performs better than the old frame, especially in hot, dry weather, and your cooling bills will drop.
Where do you put the split hole so it does not spoil the villa's street view?
We place it on the rear or side wall if possible, or somewhere not visible from the street and front garden.
Intense heat and humidity affect villas here, how do you protect the closed wall?
We use insulation that resists both moisture and heat, and paint the outer surface with heat-reflective finish to reduce the wall's heat absorption.
After conversion, will the new split be quieter than the old window unit?
Much quieter, window units vibrate in their frames and create high noise, but modern splits run noticeably silent.
