Split AC refrigerant charging in Al Wafa

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 refrigerant leak you do not notice directly, forcing the compressor to work harder to compensate for lost refrigerant. We inspect with specialist tools and fix the leak before correct charging.

Yes, intense heat increases stress and pressure in the lines, speeding leaks at weak joints or slightly damaged sections. The longer the distance between units, the faster leaks occur.

No, a quick check may not catch a slow leak, so we use a highly sensitive electronic detector that reads refrigerant even in very slow leaks and pinpoints its exact location.

Results appear immediately after correct charging, you should feel strong and steady cooling the same day. If you don't notice a clear difference, the leak may not be fully fixed and we investigate further.
