Split AC refrigerant charging in Al Zumurrud
In Al Zumurrud, north Jeddah, many split AC calls come from units that cool only at night or blow warm air. Alrabih locates the leak, repairs it, vacuums the line, then charges the correct amount to the nameplate spec.

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 Zumurrud is a relatively modern residential district with villas and medium-rise blocks spaced further apart than the central areas, making outdoor units easier to reach. Most of these homes have split systems, and heavy summer use increases copper-line leak rates, especially in older installations. Refrigerant charging demands precision to prevent the same problem recurring within weeks.
Al Zumurrud lies in north Jeddah, a modern residential district of villas and apartment blocks set further apart with wider streets.
Most homes here use one or more split units, with outdoor units typically mounted on villa walls or apartment balconies for easy access.
The AC setup in Al Zumurrud
- 1
Separate split unit per room or zone
Most villas and flats in Al Zumurrud have multiple splits, each outdoor unit on a separate wall or balcony, and each may need independent charging.
- 2
Longer copper runs between indoor and outdoor units
Wider spacing in Al Zumurrud means longer copper runs, increasing potential leak points and the need for thorough inspection.
- 3
Outdoor units sometimes shaded from direct sun
Some villas here have the outdoor unit under a patio roof or shade, which lowers thermal stress, but we inspect the condition regardless.
Before the visit
Before our visit in Al Zumurrud
- 1
Tell us exactly where the outdoor unit is
Villas and flats in Al Zumurrud vary, so let us know if the unit is on the villa's side wall, a flat's balcony, or a back courtyard.
- 2
Confirm the space between indoor and outdoor units is accessible
We need access to the copper lines and inspection along the full run from indoor to outdoor, so check nothing blocks the path.
- 3
Choose the best time for a summer visit
During peak heat, work is harder, so if possible choose early morning or after sunset for the team's safety and accurate refrigerant readings.

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 it just low on refrigerant?
Not necessarily. There may be a leak in the copper lines, and topping up without fixing it will bring the same problem back within weeks. We need to find and repair the leak first before charging.
How long does finding the leak and charging take in Al Zumurrud?
It depends on where the leak is and the length of the copper run in your villa or flat. Our team inspects on site and gives an estimate after the initial check.
Does intense summer heat speed up leaks in the copper lines?
Yes, high temperatures and direct sun on the outdoor unit raise pressure in the lines, speeding up leaks, especially where solder joints or connections are weak.
The outdoor unit is mounted on my villa wall, does the team need clear space to work?
Yes, we need clear space around the unit to access the ports, lines and inspect carefully for leaks. Let us know before the visit if there are obstacles or plants near the unit.
