Window unit to split
Window-to-split conversion in Al Fanar
In Al Fanar, far north Jeddah, converting from a window unit to a split frees your window from intense heat and seasonal noise. Alrabih seals the window opening with advanced insulation and fits the split through a small hole, restoring your flat's clean look and full natural light.

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 Fanar is a modern residential district on the northern edge with spacious villas and spread-out residential towers, and its direct exposure to north winds and sun makes window units lose cool air quickly and collect dust fast. Converting to split cuts heat loss significantly, and the advanced insulation we use protects against seasonal north winds, while mounting the outdoor unit on sun-facing walls needs extra protection from direct rays.
Al Fanar lies at far north Jeddah, a contemporary residential area of spread-out villas and towers exposed to north winds and direct sun.
Most spacious villas and flats in Al Fanar came with window units, and conversion delivers better performance against seasonal winds and intense heat.
The AC setup in Al Fanar
- 1
Protected wall core for refrigerant pipes
We drill a precise hole with extra wind and dust protection, securing the refrigerant pipes with extra care due to direct exposure to north winds.
- 2
Reinforced wind and heat-resistant closure
We use heavy insulation layers and heat-resistant plaster, with UV-protective paint, because Al Fanar faces intense heat and wind exposure.
- 3
Strong outdoor unit mount with protective shield
The unit is secured with heavy-duty metal brackets and an aluminium shield protecting it from direct sun and wind, boosting performance and lifespan.

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 Al Fanar's strong north wind weaken the new seal?
We choose materials specifically for seasonal winds, with extra insulation layers that resist wind stress without cracking or settling.
The direct sun on our north-facing facade is intense, how do you protect the outdoor unit?
We mount the unit with an aluminium shield or choose a spot with partial natural shade, extending unit life and boosting efficiency in extreme heat.
Dust builds up fast in Al Fanar, does conversion reduce maintenance?
Yes, the new split limits dust entry compared to the old window opening, so you need less frequent cleaning of pipes and filters.
Our villa has large outdoor spaces, what is the best spot for the outdoor unit?
We pick a spot that balances performance and aesthetics, away from the villa entrance and outdoor sitting areas. Usually a side corner or back wall is best.
