Charged right, not just topped up
Split AC refrigerant charging in Al Hijaz
In Al Hijaz, east Jeddah, split AC refrigerant charging is not just a top-up, it starts with finding and fixing the leak, then vacuuming the lines and filling them to the nameplate type and amount. Without this sequence, the fault returns within weeks.
- 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 Hijaz has modern villas and mid-sized residential compounds with relatively spacious outdoor areas, so outdoor units are easy to reach and maintain. But the high heat and eastern humidity strain split-unit refrigerant systems hard, especially in villas where the AC runs continuously, speeding up wear in the pipes and fittings and causing refrigerant leaks. Correct leak diagnosis is essential here before any charge.
Al Hijaz is in east Jeddah, a developed district mixing modern villas and spacious residential compounds with open outdoor areas.
Most villas and compounds in Al Hijaz run higher-capacity splits (2 to 3 tonnes or more) to handle the relentless heat.
The AC setup in Al Hijaz
- 1
High-capacity splits in villas
Villas in Al Hijaz need 2 to 3 tonne or larger splits to cover the big floor areas and constant heat, putting high stress on the refrigerant.
- 2
Long runs between indoor and outdoor units
The spacious outdoor areas mean lengthy copper pipes between the outdoor and indoor units, raising the fittings' exposure to leaks.
- 3
Outdoor units exposed to heat and humidity
Outdoor units in Al Hijaz face relentless eastern heat and humidity, speeding up corrosion of metals and pipes.
Before the visit
Before our visit in Al Hijaz
- 1
Disconnect the outdoor unit from power
Make sure the outdoor unit is disconnected from power before the team arrives, and tell us where the circuit breaker is.
- 2
Ensure safe access to the outdoor unit
Check that the outdoor unit can be reached easily and safely, especially if it sits on a roof or villa courtyard.
- 3
Confirm the refrigerant type
Find the data plate on the outdoor unit and tell us the refrigerant type shown (R22, R410A, etc.) and the nameplate capacity.

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 villa AC only cools at night, why is that?
That usually signals a refrigerant leak that worsens with the intense daytime heat. We inspect the pipes and fittings for the leak, repair it, then vacuum the line and charge it to the correct type and amount.
How often should I charge refrigerant in Al Hijaz's climate?
If the system is sound with no leak, you should not need periodic charging. Leaks are the main cause of refrigerant loss, which is why we focus on fixing the leak first to avoid the problem recurring.
Does the eastern humidity affect refrigerant pipes?
Yes, humidity accelerates corrosion in the copper fittings and speeds up leaks. Al Hijaz's humid environment calls for regular pipe checks to catch any leak early.
My outdoor unit is far from the room, does that affect charging?
Longer pipes raise the risk of leaks at fittings, especially in high heat. We inspect every fitting carefully and ensure the line is properly vacuumed before charging.
