Split AC refrigerant charging in Al Muntazah

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.

Yes, high heat increases system pressure and speeds up failure of weak seals and lines. Regular checks every six months help catch leaks early.

The location does not change how we charge, but direct sun and heat cause faster leaks. We recommend a shade structure or cover to protect the unit.

That usually means a new leak has developed, or the first leak was not fully repaired. We will inspect the lines and seals carefully to find the issue.

A raised pad is fine, but ensure there is enough space between the unit and the wall for air to circulate freely around it.
