AC installation & ducting in Rafha: before buying or handover

Before we start: what we know about Rafha

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

A typical owner in Rafha is someone who has just bought or is about to take over a rest-house or annex building and wants it cooled properly before moving in. They often arrive with a plan for a few split units, a rough idea of where the ducting should run, and a fixed date for handover. The property is simple to describe, but the choices made around air conditioning and finishing tend to decide how comfortable the building feels for years.

Rafha sits about 451 m above sea level, which is a useful detail when you plan cooling. Its summers are hot and dry, and a building at this height still needs strong heat control, so unit sizing and insulation matter as much as the price of the units themselves. For an annex or rest-house, the cost of the building work per square metre usually runs from SAR 700 to SAR 1,800, while split AC supply and installation sits at SAR 350 to SAR 900 per unit. Those ranges are wide because access, wall condition and the amount of ducting all change the final figure, which is why a site visit and quantity survey, priced at SAR 150 to SAR 400 per visit, is worth paying for before you commit.

Start by writing down the rooms you need to cool and how each will be used, then ask for a site visit so the ducting routes and unit positions are measured rather than guessed. Next, compare a quantity survey with your own list, and check whether the quote covers surface preparation, false ceilings and painting, since gypsum board false ceilings cost SAR 40 to SAR 90 per m² and painting with preparation costs SAR 8 to SAR 25 per m². Confirm the finishing scope in writing, including whether tiling with adhesive and grout, at SAR 25 to SAR 60 per m², is included. Finally, before handover, ask for each unit to be run and checked room by room, and keep the survey notes with the building papers so future repairs are easier to plan.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

Signs that call for 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

Where the problem usually comes from

• A common cause: long or poorly insulated copper runs.
• 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.
