Split AC refrigerant charging in Al Rabee

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.

The leak may be in the copper lines or unit connections. We use specialist detection equipment to pinpoint it exactly before repair.

Yes, intense heat causes constant expansion and contraction in the piping, weakening joints and creating latent leaks. We check pressure to confirm the circuit is sound.

Proximity may limit run length in some flats, but leaks usually come from age and thermal pressure, not distance itself.

If the leak is properly repaired and the circuit carefully vacuumed, yes, performance will stay stable unless a new leak develops.
