Charged right, not just topped up
Split AC refrigerant charging in Al Nur
In Al Nur, north Jeddah, split refrigerant charging needs precise diagnosis before any refill work. A unit that cools only at night or blows warm air usually signals a circuit leak that must be fixed first.
- Leak found first
- Vacuum and test
- Correct charge

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 Nur mixes modern villas with mid-rise residential blocks, and most buildings here run independent split systems or multiple split units. The circuits are prone to refrigerant leaks because of the long copper runs between indoor and outdoor units, especially in open-plan villas. Topping up refrigerant without fixing the leak first means returning within weeks.
Al Nur sits in north Jeddah, a mixed residential area of modern villas and taller apartment blocks.
Most homes and blocks here run separate or multiple split units, with copper lines typically running 5 to 15 metres from the outdoor unit.
The AC setup in Al Nur
- 1
One split unit per room or zone
Villas and blocks here typically run independent split units, each with its own circuit that can leak independently.
- 2
Long copper runs due to open-plan design
In open-plan villas, the outdoor unit may sit far from the indoor one, increasing the risk of leaks along the longer piping run.
- 3
Multi-unit distribution in apartment blocks
The area has apartment blocks where each flat has separate split units, requiring independent leak checks before charging each circuit.
Before the visit
Before our visit in Al Nur
- 1
Confirm outdoor unit location and access
Ensure the outdoor unit can be safely reached, whether on an external wall or in the yard, and tell us about any obstacles beforehand.
- 2
Disconnect power to the unit
Before our arrival, ensure the main power to the AC can be safely disconnected for work safety.
- 3
Prepare workspace around both units
We need working space around both the indoor and outdoor units to diagnose leaks, vacuum the circuit and charge it properly.

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 villa's split only cools at night, is that a leak?
Usually it is, especially if the copper runs between your indoor and outdoor units are long. We locate the leak with detection equipment and repair it before any charging.
Villas here have different layouts, how do you reach the outdoor unit?
We confirm the outdoor unit location and access beforehand. In most villas here, it sits on an external wall or the rear courtyard.
Heat is intense here in summer, does it affect the refrigerant amount needed?
Yes, high heat increases circuit pressure and reduces refrigerant efficiency. We charge to the nameplate specifications to ensure peak performance.
After charging, how soon will I notice the improvement?
If the leak is properly fixed and the circuit vacuum is done correctly, you should feel the performance improve immediately after running.
