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 Mawj is a relatively modern residential area away from the coast, with villas and mid-rise apartment blocks that offer good outdoor space for units. The south runs consistently hot in summer, so AC units carry a heavy load, and even a small refrigerant line leak shows up fast when cooling drops. A quick top-up without fixing the leak means failure again within weeks.
Al Mawj lies south of Jeddah and holds modern villas and apartment blocks with ample outdoor space.
Most split units in Al Mawj are mounted on exterior walls or open facades, making the refrigerant line easy to inspect and the outdoor unit accessible.
The AC setup in Al Mawj
- 1
Split with extended line run between indoor and outdoor
In Al Mawj villas and apartment blocks, the distance between the indoor and outdoor unit is often large, so the refrigerant line is longer and needs closer leak inspection.
- 2
Outdoor units exposed to direct sun
Most outdoor units in Al Mawj face direct sun because of the open garden, so they experience extreme heat that affects the refrigerant pressure.
- 3
Long copper lines not always fully insulated
Some refrigerant lines in Al Mawj lack full insulation, especially across open garden stretches, raising the risk of leaks at joints.
Before the visit
Before our visit in Al Mawj
- 1
Confirm team access to the garden
Let us know if the rear garden is locked or there are obstacles near the outdoor unit, so we can confirm safe access and working space.
- 2
Identify the main electrical panel
We may need to isolate the unit before inspecting the line, so tell us where the main breaker or unit isolator switch is located.
- 3
Prepare units for full inspection
Make sure the outdoor unit is clear of obstructions and debris, and any visible damage is visible to us before arrival so we can plan the work.

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 split cools only at night, is the charge low?
There may be a leak in the line or joints. We inspect the entire line for leaks first before any charging, because filling without fixing the leak will fail within weeks.
The outdoor unit sits in our garden, how do you inspect it?
We look for oil stains, frost or corrosion on the joints and pipes, which are signs of a leak. Most Al Mawj units are easy to access in the garden.
Temperatures here are very high in summer, does this speed up leaks?
Intense heat puts extra pressure on the line and joints. Any weakness in a weld or joint will show up faster in high temperatures.
After charging, how do you confirm the quantity is correct?
We measure the liquid-line temperature at the outdoor unit outlet and compare it to the unit's spec, and use a pressure gauge to confirm the charge matches the nameplate value.
