Charged right, not just topped up
Split AC refrigerant charging in Al Hamra
In Al Hamra, west Jeddah, split units underperform because humidity and intense heat accelerate refrigerant leaks. Detecting the leak, fixing it, and precise charging with the correct refrigerant is the only path to stable performance.
- 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 Hamra is a mixed residential and commercial district in west Jeddah with modern buildings from villas to multi-storey apartments. Located slightly inland from the coast but under intense summer heat and high-moderate humidity. This environment speeds up weakness in pipes and joints. Distances between indoor and outdoor units vary by building, meaning variable problem severity. Leaks may be fast or slow, but precise inspection and correct charging to specifications are always essential.
Al Hamra sits in west Jeddah slightly inland from the coast, a mixed modern residential and commercial district.
Copper runs are medium-length here, facing harsh summer heat and relatively high humidity.

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.
Intense summer heat causes weak cooling, how do I protect my unit?
Intense heat speeds up leaks if there is any weakness in the pipes. We advise checking refrigerant and pressure before summer and strong insulation for the runs.
Some days my unit cools well and others it's weak, is that normal fluctuation?
No, that points to a slow leak. Refrigerant drops under heavy use and high heat. We inspect pipes and pressure, fix any leak, then charge correctly.
My pipes run along a sun-facing wall, does that cause problems?
Yes, repeated direct heat speeds up expansion and weakness. We advise checks every four months and high-quality insulation.
If I charge now, how long before I need a refill?
If there is a leak, refrigerant may drop in weeks. We cannot give a timeframe without full inspection and fixing the leak first. We find and repair the source, then the correct charge lasts much longer.
