Before we start: what we know about Khafji

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.. Main roads in or near Khafji: King Abdullah Road.

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

Khafji sits on the Gulf coast of Saudi Arabia, and the centre of the town lies about 9 m above sea level, according to open elevation data from SRTM. It is also about 2 km from the sea coast. That combination of low elevation and close proximity to salt water shapes how air conditioning units and drain lines behave here. Humid, salt-laden air can settle on condenser coils and outdoor fans, and the land is flat enough that drainage paths need regular attention to keep water moving away from the building rather than pooling around the base of the unit.

Because the site is so close to the coast, a preventive periodic check is most useful when it covers both the outdoor unit and the condensate drain. Technicians can look for salt and dust build-up on the coils, check that the fan and casing are not corroding, and confirm that the drain line slopes correctly and is clear. A maintenance visit in Khafji typically costs SAR 150–400 per visit, which covers this kind of routine inspection and cleaning. Catching a slow drain or a dirty coil early is usually far cheaper than dealing with water damage on walls, floors or ceilings, and it keeps the system running efficiently through the hot months.

When a drain line or the area around the unit has been damaged by water or corrosion, restoration is priced per square metre, at SAR 50–150 per m². Many owners in Khafji avoid the expensive outcome by sticking to a simple schedule. Common mistakes include ignoring a slow or dripping drain until it overflows, letting dust and salt cake onto the coil without cleaning, placing the outdoor unit where water collects at ground level, and waiting for the cooling to fail before calling anyone. A regular check, booked before the summer peak, avoids most of these problems.

Preventive checks follow a written schedule instead of waiting for a fault.
