Charged right, not just topped up
Split AC refrigerant charging in Al Naeem
In Al Naeem, north Jeddah, split units need precise refrigerant charging due to concentrated heat and seasonal humidity. We diagnose joint leaks first, repair them completely, then vacuum and charge the line to the exact nameplate type and amount.

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 Naeem is a modern, planned residential area with flats and small close-set villas, limited outdoor space and direct sun exposure on facades and roofs. High summer heat and seasonal humidity together speed copper joint oxidation and refrigerant leaks faster than elsewhere. Precise leak diagnosis, complete repair and correct charging are the only way to prevent the fault returning.
Al Naeem is in north Jeddah, a modern planned residential area with close-set villas and flats with direct solar heat exposure.
Most split units here are medium-capacity (1 to 1.5 tonnes) on side walls or roofs with no protection from trees or natural shade.
The AC setup in Al Naeem
- 1
Medium split on unshaded roof
Most outdoor units here are on unshaded roofs with no tree or shade protection, directly exposed to solar heat.
- 2
Separate split units in close villas and flats
Close villas and flats need separate units, and limited building spacing may reduce outdoor unit ventilation.
- 3
Short copper run but exposed to heat
The copper run is relatively short but directly exposed to solar heat, speeding oxidation and leaks.
Before the visit

Inspect rooftop copper joints for moisture and wear
Before the visit, check rooftop joints and let us know if you see moisture, dripping or oxidation coating.
- 2
Confirm safe roof access
If the unit is on the roof, ensure the roof door and access stairs are safe and clear before the visit day.
- 3
Clear area around unit of tools and obstacles
Remove any tools or obstacles around the outdoor unit on the roof to give the team safe working space.

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.
Why does the AC cool poorly so quickly in Al Naeem's summer?
High heat and seasonal humidity together speed refrigerant leaks from joints. We find the leak, repair it and charge with correct refrigerant.
Does the close spacing of villas affect AC performance or leaks?
Close spacing may limit outdoor unit ventilation, increasing system pressure, but leaks stem from heat and humidity. We check ventilation as part of inspection.
The outdoor unit is on the roof with no shade, does this increase issues?
Yes, without shade direct heat speeds joint oxidation and leaks. If possible, a simple awning over the unit reduces direct heat.
After repair and charging, how long before new leaks in Al Naeem?
If we repair correctly and charge to exact specs, it should run efficiently long-term. But due to concentrated heat, checking joints every 6 to 12 months helps catch new weak points early.
