Split AC refrigerant charging in Umm Hablain Al Gharbiyah

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.

Probably not. This usually signals a refrigerant leak. If we charge without repairing the leak first, the problem returns quickly. We inspect with precision equipment, fix the leak, vacuum the line, then charge to specification.

Wind itself does not damage the pipes, but the dust it carries causes gradual wear on welds and joints. This wear leads to refrigerant leaks. Regular inspection helps catch leaks before you lose cooling.

If the unit blows warm or lukewarm air despite running, and the copper lines appear damp or show moisture, a leak is highly likely. We check with precision refrigerant detector equipment and confirm before any work.

Heavy dust can enter the line if exposed. That is why we use filters and protective equipment during vacuum and charging, and ensure the line is clean before final charging.
