Charged right, not just topped up
Split AC refrigerant charging in Al Andalus
In Al Andalus, west Jeddah, split AC refrigerant charging requires careful inspection before charging. A weak-cooling or warm-air unit usually has a line leak, and fixing it first protects against recurrence.
- 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.

- Run unit confirm cooling
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 Andalus is a modern district with spacious villas and upscale residential resorts, ample outdoor space allowing good placement for outdoor units. The location is close to the coast, so salt air and humidity can affect the lines and joints over time. AC units run under high pressure through the hot season, and leaks can occur at joints or in the lines themselves due to coastal corrosion. Our team detects the leak with an electronic detector, fixes it by brazing or replacing the joint, fully and thoroughly evacuates the line, and cleans it before charging to the unit's original specifications.
Al Andalus lies in west Jeddah, a modern upscale residential district of spacious villas and resorts, close to the coast.
Outdoor units here typically sit on villa roofs or rear gardens, with medium to long copper lines, exposed to coastal humidity and salt effects.
The AC setup in Al Andalus
- 1
Split unit with lines protected from sea salt
Coastal Al Andalus requires copper lines with extra protection or anti-corrosion coating, and deep evacuation to remove moisture from the line.
- 2
Outdoor units in gardens or open roofs
Spacious villas offer many outdoor spaces, but direct exposure to sea humidity and wind causes accelerated stress on the unit and lines.
- 3
Charging with very deep evacuation for moisture
Very deep and long evacuation is necessary in Al Andalus to remove all moisture from the line before charging, otherwise moisture forms quickly and affects performance.
Before the visit
Before our visit in Al Andalus
- 1
Check visible lines for corrosion signs
Before the visit, inspect visible lines for corrosion signs, discolouration or weakness, and tell the team about any observations.
- 2
Prepare a safe area for the unit and equipment
Equipment needs well-ventilated space away from excess humidity, near the outdoor unit but protected from slipping or wind.
- 3
Ask about ongoing maintenance against corrosion
After charging, ask the team about a specialist ongoing maintenance plan for the coastal environment, such as annual inspection and protective coating for lines.

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 coastal salt corrosion affect the copper lines?
Yes, coastal salt and humidity cause corrosion of lines and joints over time, especially in Al Andalus close to the sea, so lines must be inspected carefully for corrosion signs.
If the lines are corroded outside, can they be repaired or must they be replaced?
If corrosion is surface-only, we may repair it locally by brazing, but if the lines are severely corroded or perforated, they must be replaced to ensure the leak does not return.
After repair and charging, should I have the unit checked regularly for new leaks?
Yes, we recommend annual or semi-annual checks because the coastal environment speeds up corrosion, and regular inspections catch leaks early before they affect performance.
Does charging calibration differ because of high coastal humidity?
The refrigerant quantity and type do not change due to humidity, but humidity speeds up corrosion and increases leak risk, so deep evacuation before charging is essential to remove moisture from the line.
