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 Dahiyah is a residential district with modern villas and apartment blocks of varied designs, with buildings well distributed and suitable outdoor space for units. Intense summer heat and high relative humidity increase pressure on AC systems, especially when units run for long hours without break. Leaks occur gradually in connections and pipes due to constant expansion and contraction from heat swings. As refrigerant drops, the unit loses effective cooling power and may stop entirely in severe cases. Finding and fixing the leak before charging ensures the problem does not recur.
Al Dahiyah is in south Jeddah, a modern residential district with villas and apartment blocks and reasonable outdoor space for units.
Most units here are separate splits, with outdoor units distributed on walls, roofs and balconies according to the architectural design.
The AC setup in Al Dahiyah
- 1
Separate split per room or zone
Villas and apartment blocks here usually have multiple units, each with its own line and leak potential.
- 2
Outdoor units in varied configurations
Outdoor units may be on roofs, walls or balconies depending on building design, varying from home to home.
- 3
Medium to long refrigerant line runs
Distance between indoor and outdoor units is moderate to fairly long, increasing potential leak points.
Before the visit

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.
The unit is losing power, should I get it refilled or is there another problem?
Weakening cooling usually signals low refrigerant due to a leak. We check pressure first, search for the leak with specialized tools, fix it, then refill. Other issues may exist, but leaks are the most common cause.
Does humidity in the air affect how fast a leak develops?
High humidity does not directly cause leaks, but it accelerates corrosion of metals and connections, especially if moisture enters the system. This raises the chance of leaking through weak connections.
A villa may have more units than a regular house, do leak risks vary?
Yes, each unit has potential leak points in pipes and connections. A villa with three units has three times the leak points compared to a single-unit home. We inspect each unit separately.
Can you repair and charge in the same visit?
Usually yes, we repair the leak and refill in one visit. But if the leak is complex or hard to reach, we may need a second visit.
