Before we start: what we know about Baish

Team note on Baish: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Baish sits about 84 m above sea level (SRTM open elevation data).

Do owners of duplexes in Baish need to plan ducting before the air conditioners arrive? Yes, and the reason is partly the local setting. The centre of Baish sits about 84 m above sea level, so the climate and the way a building holds heat are worth considering when you plan a split system layout for a duplex. Split AC supply and installation is typically priced at SAR 350–900 per unit, which covers the indoor and outdoor units and their fitting. Ducting and the wider finishing work are priced separately, so it helps to know which items your quote includes before you compare offers.

When a technician comes to inspect a duplex, the visit usually begins with a site survey and quantity check, which is charged at SAR 150–400 per visit. The inspector looks at each floor to decide where indoor units can sit without blocking windows or doors, where outdoor units can be mounted with enough airflow, and how the pipe and duct runs will travel through walls and ceilings. They also note any false ceilings, since a gypsum board false ceiling is priced at SAR 40–90 per m² and must be opened or planned around if ducting runs above it. The survey result becomes the basis for a written scope, so ask for the measurements to be recorded in the quote.

Before the visit, gather the building plans or a rough sketch with room sizes, and list which rooms already have finished walls, tiles or painted surfaces. Note whether the duplex is still under decor works, which are priced at SAR 30–100 per m², or whether the interior is already complete. Mark any rooms that will be treated as an annex or rest-house space, since that building type is priced at SAR 700–1,800 per m². Clear access to the roof, balcony or outdoor wall where units will sit will save time during the survey. With these details ready, the inspector can give you a clear picture of what the ducting and installation will involve.

In a duplex, the two floors often share lines, so tests are done floor by floor.
