Split AC refrigerant charging in Al Riyadh

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 may be refrigerant loss but could also be a compressor or blockage issue. We check pressure, amps and temperature, and locate any leak if needed.

Yes, long lines require a higher charge. We measure the length precisely and charge to the unit type and actual line distance.

Yes, extreme heat raises pressure and temperature in the outdoor unit, accelerating leaks from weak joints and lines. Regular inspection is critical.

After the initial charge, checking pressure every three months helps catch new leaks early. Once pressure stabilises, annual checks are sufficient.
