AC installation & ducting for duplexes in Alaridah
In short: In Alaridah (Alaridah), AC installation & ducting for duplexes begins with the site survey and measurements and the written bill of quantities; nothing is opened until the position is clear. The centre of Alaridah sits about 2591 m above sea level (SRTM open elevation data). Published price: Split AC supply and installation, SAR 350–900 per unit; anything else is quoted after the inspection.
Why AC installation & ducting differs in Alaridah
The centre of Alaridah sits about 2591 m above sea level (SRTM open elevation data).
Alaridah sits at roughly 2591 metres above sea level, which places it among the higher inhabited areas where we work. That elevation means the air is thinner and temperatures can swing more between day and night than in lowland cities. For an AC installation on a duplex, this matters because the outdoor units must be positioned to shed heat efficiently and to stay clear of the wind and dust that can build up on exposed balconies and rooftops. We size and place each split unit with the local climate in mind, rather than applying a generic layout from a coastal project.
The character of the area also shapes how we plan ducting. Duplexes here are often built as two households sharing a single structure, so the ducting route has to serve each unit separately without crossing into the neighbour's space. Ceilings and wall cavities need to be opened carefully, and the access points we leave behind are planned so that future maintenance does not require breaking finished surfaces. Where a false ceiling is part of the design, we coordinate the gypsum board works with the duct runs so that the ceiling is fitted once and not reopened later. The site visit and quantity survey, priced at SAR 150–400 per visit, is the step where we confirm these routes before any material is ordered.
Owners of duplexes in this area commonly make a handful of avoidable errors. The first is choosing a unit by price alone and ignoring the supply and installation cost, which typically runs SAR 350–900 per unit, so the true budget is never clear. The second is skipping surface preparation before painting, which leads to peeling within months; interior and exterior painting with proper preparation is priced at SAR 8–25 per m², and cutting that step rarely saves money. The third is leaving plastering and tiling until after the AC is installed, which forces the crew to work around fresh finishes and damage walls. Planning the sequence from the start avoids these costs and keeps the project on track.
In a duplex, the two floors often share lines, so tests are done floor by floor.
Signs that call for AC installation & ducting
These are the signs most often linked to AC installation & ducting:
- Units that drip or cool weakly
- A new space that needs cooling
- Replacing old units
The most common causes
- A unit size that does not suit the room.
- Long or poorly insulated copper runs — we check this before anything else.
- A common cause: no proper drain line.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Site safety measures | Risks to people and property during work | Limits: throughout the work |
| Testing before closing | Faults in services before walls and ceilings are closed | Limits: done before handover |
| Written bill of quantities | Every item with its unit and quantity | Limits: final prices depend on the site visit |
| Site survey and measurements | The real quantities and conditions on site | Limits: the basis of the quote, not a substitute for it |
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.

What do I get at the end?
The unit capacities, the routes and the test results, in a technical report that carries a verification code.
Mistakes that cost more
- Choosing a unit by price, not by room size
What you receive
The written output: the unit capacities, the routes and the test results. The report is numbered and can be checked with its verification code.
Planning the visit in Alaridah
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- 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.
- 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).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
