Split AC refrigerant charging in Al Basateen

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.

Could be a leak reducing refrigerant, and summer heat speeds the loss. We find and repair the leak first before recharging.

Yes, concentrated heat and high humidity together speed copper joint oxidation and refrigerant leaks faster than cooler areas.

Yes, partial shade reduces direct heat on the unit, but trees may block ventilation. We ensure during inspection that airflow is adequate and leaves don't block openings.

If we repair the root leak properly and charge to exact specs, the unit works well. But checking joints once or twice yearly helps detect new leaks from ongoing heat and humidity.
