Split AC refrigerant charging in Abu Jaalah

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.

Slow refrigerant leak, very common in Abu Jaalah because heat and humidity degrade the long copper lines. We must fix the leak first before fresh charging, otherwise the loss returns fast.

Yes, coastal humidity speeds copper corrosion and fosters mould on insulation, which weakens pipes and raises leak risk. Protecting the lines with good insulation is essential here.

Direct heat raises internal pressure and daily copper expansion, stressing any existing tiny cracks. Covering the lines with heat-reflecting insulation reduces this stress.

If we repair properly and charge accurately, the unit runs for years. But in Abu Jaalah, ongoing stress from heat and humidity may cause new leaks after a year or two.
