Charged right, not just topped up
Split AC refrigerant charging in Al Muhammar
In Al Muhammar, east Jeddah, a split unit with weak cooling or warm air usually has a slow ongoing refrigerant leak. Alrabih's team pinpoints the leak, does a deep vacuum, and charges the line with the correct refrigerant per the unit's nameplate.

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 Muhammar is a developing residential district with relatively modern villas and medium-rise apartment blocks on reasonable plots and regular streets giving good access to outdoor units. Eastern heat and humidity are strong here, and copper pipes are prone to corrosion and slow leaks, especially at joints. Residents sometimes think adding refrigerant alone will fix it, but a leak means the refrigerant will escape again quickly. Specialist work finds and fixes the leak first, then charges correctly.
Al Muhammar sits in east Jeddah, a developing residential district with modern villas and medium-rise apartment blocks on reasonable plots.
Most units here are relatively modern splits on regular facades, but copper lines need regular checking to avoid slow leaks.

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 newer unit started cooling weakly in Al Muhammar, is that normal?
Even newer units can leak refrigerant slowly due to intense eastern heat and humidity or a faulty installation. Our team checks with high sensitivity.
My villa's outdoor unit is in sun all day, does it matter?
Yes, constant sun raises pipe and joint temperature, speeding corrosion and leaks in the foam wrap and copper lines.
If I add refrigerant myself, will that fix the problem?
Adding refrigerant without fixing the leak will cause the same fault within weeks. The leak must be found and fixed first, then correct charging done by a specialist.
My unit's lines are old with brown spots, do they need replacing?
Brown spots are signs of copper corrosion and oxidation, a potential leak source. Our team checks the pipe thickness and recommends replacement if condition is poor.
