Split AC refrigerant charging in Al Muzaira'ah

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.

Sharp thermal swings between day and night and between seasons stress metal and solder joints, even in new units. We detect the leak first with specialised equipment.

Yes, the first year includes complete thermal cycles, and new solder joints can develop small weak points. We inspect fully if cooling fades.

Yes, longer lines have more solder joints and fittings, so more leak points. We inspect every joint and connection carefully.

If we completely seal the leak, properly evacuate the line and charge correctly, the refrigerant should hold for a long time.
