Split AC refrigerant charging in Breiman

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.

It could be a slow leak in the long copper line. We inspect all connections first, fix the leak, then evacuate the line and charge it properly.

Yes, the long distance between units increases the risk of leaks in the lines. We inspect every joint and carefully evacuate the line before charging.

We inspect joints on older walls since age and moisture can cause corrosion. If the leak is inside the wall, we request careful opening of that section.

No, the amount on the nameplate is correct regardless of temperature. We follow that amount precisely, regardless of the season.
