Split AC refrigerant charging in Al Sabeel

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 clicking suggests low pressure from a refrigerant leak. We locate the leak first, repair it, evacuate the lines, then charge to the correct amount. Without these steps, the problem returns quickly.

Yes, sharp bends and stress on the copper weaken it and cause fine cracks. Rerouting pipes or adding protective sleeves after the first repair may help.

High heat raises pressure inside the pipes and stresses tiny cracks, speeding leaks. Insulating and shading the lines reduce that pressure.

If we repair properly and charge accurately, the unit works for years trouble-free. But pipes under high stress from sharp bends may leak again after a year or two if not rerouted.
