Why AC installation & ducting differs in Alquwayiyah

The centre of Alquwayiyah sits about 811 m above sea level (SRTM open elevation data).

The centre of Alquwayiyah sits about 811 m above sea level, according to SRTM open elevation data. For an AC installer, that elevation is a practical matter rather than a curiosity. Units placed on higher, exposed balconies and rooftops face stronger sun and more wind, so the outdoor condenser needs a firm, level mount and clear space around it for airflow. Our crews plan the outdoor position first and only then route the refrigerant lines, so the unit can breathe and drain properly.

Split AC supply and installation is priced at SAR 350–900 per unit, and the figure you pay depends on how much work the room needs. Before any quote, a site visit and quantity survey costs SAR 150–400 per visit. During that visit we measure the wall run, check the condition of existing ducting, and confirm where the drain and power points will sit. In apartments, ducting is often the hidden cost: old ducts that were sized for a smaller unit can reduce cooling, so we flag them early. Where a room is being refinished at the same time, the same survey also captures the gypsum false ceiling at SAR 40–90 per m² and the plastering with guides at SAR 15–35 per m², so that the AC work is scheduled before the walls are closed up and painted.

Several mistakes are easy to avoid if you plan with the installer. Owners often mount the outdoor unit before checking the wall's load and access, which leads to noise and vibration complaints later. Others skip the surface preparation before painting, which is quoted separately at SAR 8–25 per m² for interior and exterior work and is worth paying for. Some also book tiling, adhesive and grout at SAR 25–60 per m² before the AC pipes are routed, forcing a costly reopening of fresh tiles. Finally, many people compare only the per-unit price and forget that a full turnkey job, priced at SAR 900–2,500 per m², should include coordination between trades. Agree the sequence and the scope in writing, and the installation will run cleanly.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
