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 Sham is a dense historic quarter of closely packed older buildings with small flats and commercial units over multiple floors. Spaces are tight, streets are very narrow, and many split units are old or installed in harsh conditions owing to building density, coastal humidity and dust. Slow refrigerant leaks are common in these older units, and tenants often notice poor cooling only after weeks of gradual decline.
Harat Al Sham sits in old downtown Jeddah, a dense historic zone of closely built structures and narrow streets near the market.
Most units here are relatively old splits with pipes exposed to coastal salt and humidity, and outdoor units often crammed on narrow facades or window ledges.
The AC setup in Harat Al Sham
- 1
Old split on a narrow window or facade
Most outdoor units here sit on narrow windows or facades, making inspection and maintenance challenging.
- 2
Copper pipes exposed to salt and humidity
Pipes are fixed directly to exterior walls, exposed to coastal salt, humidity and dust.
- 3
Compact indoor units in tight rooms
Flats are small and spaces confined, with indoor units sometimes mounted tightly, making coil and fan access difficult.
Before 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.
My old unit constantly leaks refrigerant, is there a permanent fix?
Yes, we locate the leak precisely with detector equipment, seal the crack or hole with professional soldering, vacuum the lines, then recharge properly. The correct repair stops the leak permanently.
The streets are very narrow, can you bring equipment to the unit?
Yes, our team is used to narrow streets and closely built blocks. We carry tools by hand and agree the closest parking point, handling the rest from inside the building.
Humidity is intense here and salt spray coats the facades, does that accelerate leaks?
Yes, salt and humidity oxidize copper pipes and joints rapidly. We use sensitive leak detection and inspect joints and micro-holes carefully, then coat outdoor pipes with protective finish after repair.
Does moisture inside the lines reduce new refrigerant efficiency?
Yes, moisture in the lines cuts refrigerant efficiency and may damage the compressor. We use professional vacuum pumps to remove all moisture and air before new refrigerant is added.
