Charged right, not just topped up
Split AC refrigerant charging in Al Ma'rifah
In Al Ma'rifah, north Jeddah, split AC refrigerant charging starts with finding the real cause. A unit that cools poorly or blows warm air often has a line leak, and fixing it before charging prevents the same problem returning.
- 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 Ma'rifah is a modern district with spacious villas and tall apartment blocks, outdoor space varies between balconies, roofs and rear gardens. AC units run under high pressure through the long summer, and refrigerant leaks typically occur at joints or line bends. Our team diagnoses the site precisely, fixes the leak by brazing or replacing the joint, fully evacuates the line and charges it to the unit's original specifications.
Al Ma'rifah is in north Jeddah, a modern residential district of villas and tall blocks with varied outdoor space.
Outdoor units here are spread across villa roofs and apartment balconies, copper lines are medium length with several joints, each a potential leak point.

Confirm the team can reach the outdoor unit
Check that the balcony or roof is safely accessible, and notify anyone else in the building so they are not surprised by the team's presence.
- 2
Prepare a safe area for vacuum and charging equipment
Vacuum and charging equipment needs safe space near the unit, clear of items that might impede the team's movement.
- 3
Ask about regular maintenance after charging
After fixing and charging, ask the team about a regular maintenance plan to keep the unit in good condition; annual checks help spot leaks early.

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.
Does a refrigerant leak always happen at a joint?
Joints are the main leak sites, but the lines themselves can corrode outside or be pierced by sharp objects. We use an electronic detector to find any leak anywhere.
Our balconies and roofs are exposed to sun and wind, does that cause leaks?
Yes, expansion and contraction from intense heat and wind weakens joints and lines over time, especially in coastal areas, so regular checks help spot leaks early.
How long does line evacuation take before charging?
It depends on line length and the number of joints, but deep evacuation is essential to remove all air and moisture, otherwise the unit's efficiency suffers.
After fixing the leak and charging, when should I expect cooling to improve?
Improvement shows right after full, clean charging, but check for new leaks a week later, as the problem returns if the root cause was not fully fixed.
