Riyadh's city centre sits about 637 m above sea level, which gives the city a dry, high-plateau climate with hot summers and strong daytime heat. For duplexes in this area, that elevation and climate mean cooling demand is high for much of the year, so air conditioning is not a luxury but a core part of how the home works. Installation has to be planned around heavy daily use, and the system must be sized and placed so that each floor of the duplex can be cooled without relying on overworked units.
Because the work is tied to the local heat, we start every job with a site visit and quantity survey at SAR 150 per visit. This lets us measure the rooms on both floors, check where the outdoor units can sit for airflow, and map the ducting route before any cost is agreed. Split AC supply and installation is priced at SAR 370–945 per unit, and the final figure depends on the unit size, the mounting position and how far the pipework must run between indoor and outdoor sections. Where a duplex needs ducting through a ceiling, we also plan for gypsum board false ceiling from SAR 45 per m², so that the ducts are hidden and the finish stays neat.
Owners of duplexes in this city often make the same avoidable mistakes. The first is to leave ducting until after the walls are painted or the floors are tiled, which forces cuts and repairs that cost more than planning ahead would have. The second is to choose unit sizes by guesswork rather than by a proper survey of each room's heat load, leaving upstairs rooms hot while downstairs runs cold. The third is to treat painting, plastering and tiling as separate jobs with no shared schedule, so that finished surfaces are damaged by later installation work. Planning all of these together from the survey stage is the practical way to avoid them.
In a duplex, the two floors often share lines, so tests are done floor by floor.
When do you need AC installation & ducting?
If you notice one of these signs in Riyadh, it is a good moment to talk to the team:
- A new space that needs cooling
- Units that drip or cool weakly
- Replacing old units
The most common causes
- Long or poorly insulated copper runs — we check this before anything else.
- A unit size that does not suit the room — we check this before anything else.
- No proper drain line — we check this before anything else.
How we choose the tool in Riyadh
| Tool | What it finds | When we use it in Riyadh |
|---|---|---|
| Testing before closing | Faults in services before walls and ceilings are closed | Limits: done before handover |
| Site safety measures | Risks to people and property during work | Limits: throughout the work |
| Site survey and measurements | The real quantities and conditions on site | Limits: the basis of the quote, not a substitute for it |
| Written bill of quantities | Every item with its unit and quantity | Limits: final prices depend on the site visit |
From the first visit to the report
- Survey: Room sizes and unit positions are checked.
- Sizing: Unit capacity is chosen for each room.
- Installation: Units, copper, drain and breaker are installed.
- Testing: Pressure, cooling and drainage are checked.

Common questions about AC installation & ducting in Riyadh
What is the best thermal insulation material for a humid climate in the Eastern Province?
In humid areas, it is preferable to choose materials with low water absorption, such as extruded polystyrene or polyurethane foam, because they retain their efficiency in the presence of moisture. However, the final choice depends on the type of surface, the budget, and the contractor's recommendation after inspection.
What is the drying time for the floor before use?
The drying time varies depending on the system type, layer thickness, and site temperature. The installer will specify it within the scope of work.
Does detecting bathroom leaks require breaking tiles?
Usually not. Modern tools such as thermal cameras, electronic listening devices, and pressure testing pinpoint the source of a leak with high accuracy. If breaking is necessary, it is limited to the repair point only, after the location has been confirmed.
Where does AC installation & ducting for duplexes start in Riyadh?
We start with survey (room sizes and unit positions are checked), then sizing (unit capacity is chosen for each room).
What does AC installation & ducting cost in Riyadh?
From our published price list: Split AC supply and installation SAR 370–945 per unit. Quantities are confirmed at the inspection.
What do I receive after the work?
The unit capacities, the routes and the test results, in a technical report that carries a verification code.
What we advise against
- Choosing a unit by price, not by room size
What you get after the work
You receive: the unit capacities, the routes and the test results, in a technical report with a verification code.
Planning the visit in Riyadh
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
