An owner of a residential villa or apartment in Riyadh often reaches the point where the existing air conditioning no longer keeps up, or a new floor or annex needs cooling from scratch. Perhaps the family has grown, a room has been converted, or the old split units are tired after several summers. The question is usually not only which units to buy, but how the pipes, drainage and outdoor units will fit into a building that was not designed with ducting in mind.
The centre of Riyadh sits about 637 m above sea level, which is not high enough to bring a dramatic change in temperature, but the city's hot, dry summers still put heavy demand on cooling equipment. For a homeowner this means units should be sized for the room and the sun exposure rather than chosen by price alone, and outdoor units need clear airflow and a stable mounting point. Cost planning is also helped by knowing that split AC supply and installation is quoted at SAR 370–945 per unit, so the budget for a multi-room home can add up quickly and is worth checking before work begins.
A practical sequence helps keep the job under control. Start with a site visit and quantity survey, which is quoted at SAR 150 per visit, so the installer can measure rooms, mark the route for pipes and drainage, and identify where wall or ceiling openings will be needed. Next, agree the layout for outdoor units, avoiding spots where hot air will recirculate. Then plan any finishing around the work: if a gypsum board false ceiling is needed to hide ducting, it starts from SAR 45 per m², and plastering with guides runs at SAR 15–35 per m², so patching should be scheduled after the pipes are fixed. Finish with painting, which includes surface preparation at SAR 18–25 per m², and check every unit runs and drains properly before handover.
For a residential building, shared risers, tanks and pumps are checked as one system.
When do you need AC installation & ducting?
These are the signs most often linked to AC installation & ducting:
- A new space that needs cooling
- Units that drip or cool weakly
- Replacing old units
Causes we see in the field
- Long or poorly insulated copper runs — we check this before anything else.
- A common cause: a unit size that does not suit the room.
- No proper drain line — we check this before anything else.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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 |
The steps in order
- 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.

Short answers for 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.
What is the first step of AC installation & ducting for residential buildings?
We start with survey (room sizes and unit positions are checked), then sizing (unit capacity is chosen for each room).

If you live in Riyadh and are new to the area
- 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.
