Split AC refrigerant charging in Al Karamah

Usually not. Charging is done at the service valve on the outdoor unit, and if the leak is at the flare joints behind the indoor unit we reach them by lifting the lower cover or tilting the unit on its bracket. It only comes down when the joint is inside the wall.

The most common points in a wall split are the flare joints at the indoor unit, which loosen over time from vibration, and the service valves at the outdoor unit. In Jeddah's humid and salty air, oxidation at copper connections can develop faster, which raises the chance of a leak.

When a split is moved, the flare joints are disconnected and remade, and this is when air and moisture enter the line. A full vacuum before charging becomes especially important, and the technician checks every remade flare joint before the line is closed.

This is a common sign of low refrigerant. At night, lower outdoor air temperature lets the compressor partly compensate for the shortage. During Jeddah's daytime heat, the reduced charge is not enough and cooling weakens or stops. The inspection confirms whether this is the cause or whether another factor such as the compressor or capacitor is involved.

Yes, a longer copper pipe run between the two units requires more refrigerant. The site inspection measures the actual run length, and the technician sets the charge amount based on the nameplate figure and the installed pipe length.

Yes, longer distances require significantly more refrigerant and longer evacuation time. The charge amount is calculated based on actual line length and diameter.

We use specialist detection equipment to trace nitrogen or refrigerant escape along every metre of the line, checking for any corrosion or pinhole damage on the outer surface.

Yes, intense heat raises pressure in longer lines significantly, speeding leaks from weak points. If we don't seal the leak properly, refrigerant escapes fast in summer.

High locations require safety equipment and specialist skills, but don't affect the charging process itself. We ensure full safety precautions when working at height.
