Why AC installation & ducting differs in Khafji

Khafji is about 2 km from the sea coast (OpenStreetMap). The centre of Khafji sits about 9 m above sea level (SRTM open elevation data).

Main roads in or near Khafji: King Abdullah Road. Team note on Khafji: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins..

Will a flat or villa in Khafji, sitting close to the coast, really need a different approach to air conditioning? The answer starts with the place itself. The centre of Khafji sits about 9 m above sea level, and the town is about 2 km from the sea coast. Those facts matter when we plan where an outdoor unit can sit, how condensate drains away, and how the ducting runs from the plant to each room. A split unit costs SAR 350–900 per unit for supply and installation, but the route it takes through a building is what decides whether it performs well for years.

Our inspection starts with a site visit and quantity survey, which is charged at SAR 150–400 per visit. During the visit we walk the building and record room sizes, ceiling heights, wall openings, and the existing electrical points. We check where the outdoor units can be mounted without blocking light or access, and we note any existing ducting, false ceilings, or finishes that will be disturbed. For residential buildings with ducted systems, we measure the routes so the duct sizes and lengths are set on paper before any material is ordered. The survey gives you a written picture of the work, so the figures you approve are based on what is actually in the building.

Before the visit, it helps to gather a few things. Have the plan of the building or a rough sketch with room dimensions ready, and note which rooms you want cooled. Tell us if the ceilings are gypsum board, plastered, or tiled, since that affects how ducting is concealed. Clear access to the roof, balcony, or wall where outdoor units will sit, and make sure someone can open the rooms on the day. If you are planning other works at the same time, such as painting at SAR 8–25 per m², plastering at SAR 15–35 per m², or a gypsum false ceiling at SAR 40–90 per m², mention them now so the survey can account for them.

For a residential building, shared risers, tanks and pumps are checked as one system.

Signs worth paying attention to

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.
• No proper drain line — we check this before anything else.

How we choose the tool in Khafji

The steps in order

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.
