AC installation & ducting in Rafha: the local context

The centre of Rafha sits about 451 m above sea level (SRTM open elevation data).

Does a rest house or farm in Rafha, sitting around 451 m above sea level, need a different approach to air conditioning than a city flat? The short answer is yes, because the building's size, layout and existing ducting all shape what a sound installation looks like. Split units are typically priced at SAR 350–900 per unit for supply and installation, but the real cost depends on how many rooms need cooling and whether ducting must be added or repaired. Ducted systems for larger annexes and farm buildings are usually planned together with the wider fit-out, where building work runs from SAR 700–1,800 per m² for an annex or rest-house structure.

The first step is a site visit and quantity survey, which generally costs SAR 150–400 per visit. During the visit, the inspector walks the building to measure room areas, check wall and ceiling openings, and note where outdoor condensers can be mounted with clear airflow. They look at existing electrical capacity, assess the condition of any ducting already in place, and identify where a gypsum board false ceiling, which runs SAR 40–90 per m², might be needed to hide duct runs neatly. The surveyor also checks surfaces that will be disturbed, so that plastering with guides (SAR 15–35 per m²) or painting with surface preparation (SAR 8–25 per m²) can be scoped in the same quote rather than added later.

Before the visit, gather the building's approximate floor plan with room sizes, a list of rooms you want cooled, and any existing AC or duct details you have. Note which areas get the most sun and which are used most often, since this affects unit sizing. Clear access to the roof, plant area and external walls will save time, and it helps to know whether you plan a light refresh or a full finishing package, which runs SAR 300–800 per m² up to handover. Having these details ready lets the survey produce a clear, comparable quote for your rest house or farm.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs that call for AC installation & ducting

The following signs are worth checking before they grow:

• Replacing old units
• Units that drip or cool weakly
• A new space that needs cooling

Where the problem usually comes from

• A common cause: no proper drain line.
• A unit size that does not suit the room.
• Long or poorly insulated copper runs — we check this before anything else.

Tools we use in Rafha

How the work is done, step by step

1. Survey: Room sizes and unit positions are checked.
2. Sizing: Unit capacity is chosen for each room.
3. Installation: Units, copper, drain and breaker are installed.
4. Testing: Pressure, cooling and drainage are checked.
