Charged right, not just topped up
Split AC refrigerant charging in Al Ruhaili
In Al Ruhaili, north-east Jeddah, split units cooling weakly need more than a quick top-up. A leak test, repair and full evacuation charge is the permanent fix.
- 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 Ruhaili is a recently developed district with scattered villas and mid-rise apartment blocks across open spaces and wide streets. Split units are common in every home and flat, with copper runs extending from indoors to outdoors through walls and facades exposed to hot air and winds. Sustained high heat and dry conditions accelerate seal degradation at joints and connection points.
Al Ruhaili is in north-east Jeddah, a modern district of scattered villas and mid-rise residential blocks with wide-open spaces.
Most villas and blocks here have relatively recent splits, but the copper lines face direct exposure to hot winds and extreme dryness.

Clearly identify outdoor unit location
Tell us exactly where the outdoor unit is mounted, on a wall, roof or garden, so we can reach it easily.
- 2
Ensure clear access indoors and outdoors
Make sure the path from the indoor unit to the outdoor connection is clear of furniture or obstacles for inspection.

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 is new but cooling weakly after one year, what causes this?
Usually a slow leak in the lines or at connection points. We use a leak detector, fix the spot, then fully evacuate and recharge the system.
Our strong winds and extreme heat affect the copper, do they cause leaks?
Yes, extreme temperature swings and dry conditions weaken joints and insulation seals. We inspect lines carefully and repair any weak points before the full charge.
How often should I request refrigerant top-ups yearly in Al Ruhaili?
If the system is properly sealed, no annual top-ups are needed. If you need repeated charging, there is an active leak requiring detection and repair.
What checks do you do before a full refrigerant charge?
We use a leak detector on all lines and joints, repair any leak found, evacuate the system with a vacuum pump to remove moisture and air, then charge to the correct type and amount.
