Charged right, not just topped up
Split AC refrigerant charging in Al Amwaj
In Al Amwaj, north Jeddah, split units need precise refrigerant charging because the humid coastal climate accelerates leaks in the copper joints. We find the leak first, then vacuum and clean the line, and charge it to the 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 Amwaj is a modern area with spacious villas and residential flats and adequate outdoor space, with many outdoor units sited away from direct sea spray on front facades. Yet the high humidity and salt in the air erode refrigerant efficiency over time and cause leaks in the joints, reducing the unit's cooling output. Early diagnosis, proper leak repair, and correct recharging keep the unit from failing repeatedly.
Al Amwaj is in north Jeddah, a modern area of villas and flats with generous outdoor space away from dense urban pressure.
Most split units here have high capacity (1.5 to 2.5 tonnes) spread over large areas, with outdoor units usually sited in a garden or yard away from sea spray.
The AC setup in Al Amwaj
- 1
High-capacity split with distant outdoor unit
Most Al Amwaj villas and flats need high capacity (1.5 to 2.5 tonnes) with a long copper run from the garden unit to indoors.
- 2
Multiple split units in a single villa
Modern Al Amwaj villas typically need multiple units (bedroom, living room, kitchen), each requiring separate inspection and charging.
- 3
Long copper runs exposed to salt air
Long copper joints between outdoor units in yards and indoors are directly exposed to humidity and salt, speeding leaks and corrosion.
Before the visit
Before our visit in Al Amwaj
- 1
Ensure access to the outdoor unit
If the unit is in a garden or yard, ensure the path is clear and safe to reach it before the inspection and charging appointment.
- 2
Note visible copper joint locations
If you notice moisture or damage on copper joints between outdoor and indoor units, point them out to speed up leak diagnosis.

Clear a safe space around the outdoor unit
Ensure no dense plants or obstacles block the team's safe access to the joints and drain pan for inspection and maintenance.

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.
The AC cools only at night in Al Amwaj, is it low refrigerant?
It could be low refrigerant, but the cause is usually a leak in the joints from humidity and salt air. We locate and repair the leak first before recharging to prevent the fault returning.
Does coastal exposure speed up refrigerant leaks in Al Amwaj?
Yes, high humidity and salt in the air oxidise copper joints faster than inland areas, so refrigerant leaks happen more quickly and often.
My outdoor unit is far away in the garden, does this affect charging?
Distance doesn't affect charging accuracy, but the long copper run increases leak risk from vibration and weather, so we recommend regular joint inspections.
After charging, how long does the refrigerant last before the next leak?
If we repair the leak properly and charge to the correct type and amount, it should last a long time. But in Al Amwaj, salt and humidity mean checking the joints yearly or every two years helps catch new leaks early.
