Split AC refrigerant charging in Al Hamdaniyah

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.

Usually a slow leak in the lines. We inspect every joint on roof and walls, fix the leak, then evacuate and properly charge.

Yes, copper lines on roofs face sun and weather, speeding rust and leaks. We inspect them closely and repair any weak sections.

Yes, this is a common leak point in older buildings. We inspect it closely and tighten or replace the seal if needed.

If there is a real leak, repeated refilling will not solve it. We fix the leak first, then a single charge should last for years if the repairs are correct.
