Why owners make the switch

  1. 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. 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. 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. 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. 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. 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. 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 Majami' is a modern district featuring carefully designed spacious villas and luxury flats with refined architectural windows and high-spec finishes, many still retaining traditional window units that block natural light and spoil the overall look. Upgrading to a modern split requires skilled precise work to seal the opening with comprehensive insulation against coastal heat and humidity whilst maintaining high architectural quality. The open layouts and wide spaces in Al Majami' provide substantial freedom to site the outdoor unit discreetly and safely.

Al Majami' is in far north Jeddah, a district of spacious modern villas and luxury flats with refined architectural design.

Most villas and flats in Al Majami' are recently built to high standards, and old window units in them are mismatched with the finish level.

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.

My villa has contemporary architectural design, can you maintain its design consistency?

Yes, we install the split with precision to preserve your design, and site the outdoor unit to match your overall architecture.

Al Majami' has community gardens and private designs, are there installation restrictions?

Some communities may need management approval, so we coordinate with you or them beforehand to ensure design compliance.

My flat is in a high-rise, can the outdoor unit be safely mounted on the balcony?

Yes, we use secure strong mounting and check that your balcony or roof is safe and can support the unit before fixing it.

Coastal winter weather is cool and humid, are there issues with paint and seal?

The paint and insulation we use is formulated for high humidity and coastal weather and will withstand both winter and summer efficiently.
