Charged right, not just topped up
Split AC refrigerant charging in Al Asalah
In Al Asalah, north Jeddah, split AC refrigerant charging demands careful diagnosis before any top-up, because a unit that cools only at night or blows warm air may signal a leak in the copper lines.
- 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 Asalah is a modern residential district of detached villas and apartment blocks with relatively open outdoor spaces, giving room to place and access the outdoor units for maintenance. Yet the intense heat and direct sun exposure on roofs and external walls increases stress on the refrigerant and copper lines, especially in summer. Finding and fixing the leak, then vacuuming and charging to the nameplate type and amount, is essential to prevent the fault from returning within weeks.
Al Asalah sits in north Jeddah, a modern residential area of villas and apartment blocks with open outdoor spaces.
Most outdoor units here are roof-mounted on villas and blocks with direct sun exposure, raising refrigerant temperature and pressure stress on the copper lines.
The AC setup in Al Asalah
- 1
Split with outdoor unit on the roof
Most villas and blocks here have the outdoor unit roof-mounted with full sun exposure, requiring careful attention when checking and refilling refrigerant.
- 2
Relatively long copper runs
The distance from the roof-mounted outdoor unit to the indoor unit is often long in some villas, raising the leak risk over the copper length.
- 3
Varied thermal insulation in outdoor spaces
Some outdoor units sit near exposed walls or face hot winds, affecting refrigerant-pressure stability.
Before the visit
Before our visit in Al Asalah
- 1
Ensure safe access to the roof
Let us know if there are safe ladders or reliable access steps to the roof where the outdoor unit sits.
- 2
Confirm electrical supply is available
We need an electrical outlet near the outdoor unit to run the diagnostic and evacuation and refilling equipment.
- 3
Clearly identify the indoor unit location
Give us exact details of the indoor unit's location, since it determines the copper-run length and how it may be affected by any leak.

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 unit cools only at night, is a simple refrigerant top-up enough?
No, that symptom usually signals a copper-line leak. We must find and fix the leak first, then vacuum and refill the line to the correct amount, or the fault will return within weeks.
Al Asalah roofs get full-day sun exposure, does that affect the refrigerant?
Yes, intense heat and direct sun exposure raise refrigerant pressure and strain the copper lines and the whole unit, so filling to the exact amount becomes more critical in these conditions.
The outdoor spaces here are wide, does that make accessing the unit easier?
Yes, the wide spaces and detached villas make it safer and easier to reach the outdoor unit on the roof, and give us room to work precisely when checking for leaks and refilling.
How often should I have the refrigerant checked in a district like Al Asalah?
That depends on the unit type and usage, but the intense sun and heat make a check before summer wise, and if you notice weak cooling, call us right away.
