Charged right, not just topped up
Split AC refrigerant charging in Al Faisaliyah
In Al Faisaliyah, central Jeddah, many split units cool only at night or blow warm air and need refrigerant charging. Alrabih's team locates and fixes the leak first, then vacuums the lines and charges them to the nameplate type and amount.

When your split needs a refrigerant charge
- 1
Weak cooling with a clean filter
If the filter is clean and the compressor is running but the air from the indoor unit is barely cool, the cause is usually low refrigerant from a leak at the flare joints or the outdoor service valves.
- 2
Frost on the pipes or unusual water drips
Frost on the large pipe at the indoor unit, or water dripping from the unit in an unusual way, means refrigerant pressure has dropped below the range set by the manufacturer. The inspection finds the leak before any charging begins.
- 3
A split that was moved and refitted
When a split is removed for painting, renovation or a room move, the flare joints are disconnected and remade. These joints are the most likely source of a leak after refitting, and the system needs a careful check, a vacuum and a fresh charge.
Who it's for
Your bedroom split cools only at night
We find and fix the leak at the flare joints, then vacuum and charge to the nameplate refrigerant type.
Ask on WhatsAppYour split was removed for renovation and refitted
We inspect every remade flare joint, vacuum the full line, then charge and confirm cooling has returned.

How we work
How we work
- 1
Describe the fault
Tell us on WhatsApp what is happening and send a photo of the outdoor unit nameplate so we know the refrigerant type before we arrive.
- 2
Inspect and find the leak
The technician checks the flare joints at the indoor unit and the service valves at the outdoor unit and locates the leak before taking any further step.
- 3
Repair and vacuum
We tighten or remake the flare joint as its condition requires, then vacuum the line and watch the pressure hold to confirm the line is tight.
- 4
Charge and run
We charge with the nameplate type at the amount the inspection determines, then run the unit and confirm that cooling has returned to the normal level.
Fix the leak first or just top it up?
| Alrabih | The usual way | |
|---|---|---|
| The leak | Found and fixed first | Ignored, charged over it |
| Flare joint | Checked, remade if needed | Not checked |
| Vacuum | Before every charge | Often skipped |
| Refrigerant type | Nameplate only | Whatever is available |
| Line moisture | Removed by vacuum | Left inside the line |

What sets this district apart
Al Faisaliyah is a modern residential district with villas and medium-sized apartment blocks with reasonable outdoor space for units. Most AC here are split systems in bedrooms and living areas, and leaks often occur in the copper lines due to intense heat and coastal humidity. Charging refrigerant without fixing the leak first means the problem returns within weeks, so a full system inspection before charging is essential.
Al Faisaliyah sits in central Jeddah, a modern residential district mixing villas and apartment blocks with ordered planning and wide streets.
Most split units here run long copper lines between the indoor and outdoor sections, raising the leak risk in the coastal climate.
The AC setup in Al Faisaliyah
- 1
Independent split units in villas
Al Faisaliyah villas typically have one or more split units, each with separate copper lines run through the ceiling or walls.
- 2
Long copper lines between indoor and outdoor units
The distance between indoor and outdoor units in villas can reach 10 metres, increasing potential leak points along the run.
- 3
Outdoor units mounted on walls or roofs
Outdoor units in villas are often mounted on side walls or roofs, making access for servicing and diagnosis straightforward.

FAQ
Questions about Split AC refrigerant charging
Does the split have to come off the wall to be recharged?
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.
Where do leaks usually occur in a wall split?
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.
Does the charging process differ when a split has been moved?
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.
Why does my split cool only at night?
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.
Does the length of the copper pipe run affect how much refrigerant is needed?
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.
My unit cools only at night, is it low on refrigerant?
It may be low, but the cause is usually a leak in the copper lines. We inspect the system first to find and fix the leak before charging, otherwise the problem returns.
The villas here have big outdoor spaces, does that help with the repair?
Yes, adequate outdoor space makes accessing the outdoor unit and lines easier and speeds up diagnosis and repair.
Coastal heat and humidity cause repeated leaks, how do we protect the lines?
Leaks typically occur in copper lines or fittings when exposed to heat and humidity. Regular inspection and early repair of any leaks extend the system's life.
How many times must the lines be checked before charging?
We check the entire line for leaks with professional leak detection, and vacuum the air from the lines before the final refrigerant charge.
