Charged right, not just topped up
Split AC refrigerant charging in Harat Al Mazloum
Split AC refrigerant charging in Harat Al Mazloum begins with tracing leaks in the tight, corroded copper lines, then fully evacuating and charging with the correct refrigerant. A unit that cools weakly or blows warm air needs full diagnostic work first.

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
Harat Al Mazloum is among Jeddah's oldest quarters, with tightly packed buildings containing small flats and ground-floor shops. Copper lines here are mostly exposed to the elements and high coastal humidity, causing gradual corrosion and slow leaks. Tracing the leak in these dense buildings takes extra time and care not to disturb close neighbours.
Harat Al Mazloum lies in Jeddah's historic downtown, an old quarter of closely built blocks with narrow streets and proximity to the sea.
Most units here are older splits with exposed copper lines on narrow facades, prone to rapid corrosion.
The AC setup in Harat Al Mazloum
- 1
Older split with exposed, corroded lines
Most units here have exposed copper lines on narrow outer walls, showing clear green corrosion marks.
- 2
Window units still in some older flats
Some of the oldest flats here still use window units instead of splits, requiring separate treatment.
- 3
Short lines but in cramped spaces
Although copper runs are relatively short due to tight spaces, they are exposed to catching and damage from moving furniture and hanging items.
Before the visit
Before our visit in Harat Al Mazloum
- 1
Clear space around the outdoor unit
Remove any washing lines, furniture or hanging items around the outdoor unit to avoid damage or obstruction.
- 2
Notify neighbours before the visit
Because buildings sit so close, let neighbouring residents know about the visit time to avoid disturbance or misunderstanding.
- 3
Confirm access and electrical supply
Confirm the path to the outdoor unit is safe and that power supply is stable and uninterrupted throughout 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.
These buildings are very old, does refrigerant last as long in them as in newer areas?
No, coastal salt and high humidity speed copper corrosion. Refrigerant leaks faster here, so units need regular checks and any leaks sealed before new charging.
The streets are very narrow, how do you get your heavy equipment in?
Our team carries diagnostic and charging tools by hand when needed, and we agree on the closest safe parking point before the visit.
Does coastal humidity affect leaking, and how often do I need recharging?
Yes, humidity and salt speed corrosion and leaks. If we find a leak, we seal it first, otherwise the new charge will escape quickly. Duration depends on leak size and repair quality.
Copper lines are exposed on the walls here, does that increase leaking?
Yes, exposed lines take direct sun, humidity and salt, speeding corrosion and pinhole leaks. Wrapping them in insulation or protective sleeves can extend their life.
