Split AC refrigerant charging in Abhur Al Janoubiyah

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 low refrigerant from joint leaks. Sea air and salt corrode copper joints quickly, so we find and repair the leak, then charge with the correct refrigerant.

Yes, humidity and salt speed copper oxidation, so refrigerant leaks faster and more often than inland areas.

Yes, direct sea spray exposure means regular checks of joints and pipes are essential to catch leaks early before complete refrigerant loss.

If we repair the original leak properly, it should last well. But due to sea salt, checking joints every 6 to 12 months helps catch new leaks quickly.
