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 Mawaddah is a densely packed district of villas and mid-rise apartments with limited streets and closely clustered developments. Split unit density here is very high, with copper lines mounted on shared walls or projects very close together. Moisture and dust from the streets and tight spaces accelerate corrosion in joints and lines. Precise leak location is critical here because urban congestion restricts repair and charging options.
Al Mawaddah sits in east Jeddah, a densely packed residential district of closely spaced villas and apartment blocks.
Multiple split units crowd each villa and block, with lines mounted on narrow external walls because gaps between buildings are tight.
The AC setup in Al Mawaddah
- 1
Multiple units on shared walls
Each villa and block has several split units mounted on narrow external walls due to urban density.
- 2
Short but densely packed copper lines
Lines are relatively short between indoor and outdoor units, but sheer quantity in the tight space creates high density.
- 3
Multiple compressors on one property
A villa or block may have two or more compressors depending on the number of indoor and outdoor zones.

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.
Units are very close together, does one interfere with another?
No, but units run at higher load due to congestion, which can accelerate leaks. We inspect each unit separately and diagnose its individual leak.
Lines are on shared walls, how do you repair a leak?
We locate the exact leak with a detector, then repair the fitting or cut out the leaky section as needed. Occasionally we coordinate with neighbours.
Does dust and humidity here speed up corrosion?
Very much so, dust and moisture settle on fittings and metals, accelerating corrosion. Regular cleaning and inspection are essential here.
After repairing the leak and charging, is the problem solved?
If we have sealed the original leak properly and fully vacuumed and charged the line correctly, the problem should be solved. However, annual checks help catch new issues.
