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.

- Vacuum line and pressure test
- Charge to nameplate refrigerant type
- Run unit confirm cooling
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 Mahamid is an advanced residential district in east Jeddah with modern villas and blocks on carefully planned sites, most units equipped with modern splits. The intense dry eastern heat in summer stresses the cooling system, and daily temperature swings cause continuous expansion and contraction in copper pipes. This repeated thermal stress weakens joints and pipes, causing slow leaks. When a leak begins, refrigerant depletes gradually and cooling efficiency drops, so charging alone without fixing the underlying leak will cause the same fault to return shortly.
Al Mahamid sits in east Jeddah, an advanced residential zone of modern villas and planned apartment blocks.
Most villas and flats have modern high-efficiency split units, with outdoor units on planned walls and roofs designed to handle eastern heat.
The AC setup in Al Mahamid
- 1
Modern split unit per residential unit
Modern villas and flats here have high-efficiency split units, each with its own protected lines yet exposed to eastern heat.
- 2
Outdoor units on planned walls and roofs
Outdoor units are placed in planned locations to withstand heat, but intense eastern temperatures still stress all pipes.
- 3
Copper runs protected but under thermal stress
Pipes here are better protected than in other districts, but continuous eastern temperature swings cause expansion and contraction that weakens joints.
Before the visit

- 1
Pinpoint the outdoor unit location
Tell us if the outdoor unit is on a roof, wall or balcony, as this affects how the team accesses it.
- 2
Clear the area around the indoor unit
Ensure the indoor unit is clear of furniture, curtains and clutter so the team can access it directly.
- 3
Provide a strong and safe power outlet
Vacuuming and charging equipment need a high-capacity outlet. Confirm it is safe and the wiring is sound.

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 unit began cooling slowly over time, what is causing it?
A slow leak gradually depletes the refrigerant. Intense eastern heat and daily temperature swings accelerate leak development. We locate and fix first, then charge.
Al Mahamid is modern, are new units less prone to leaking?
Modern units are better built, but intense eastern heat and continuous pressure affect any system. Thermal expansion and contraction from daily temperature swings is the main cause.
Do I need a full clean before recharging?
Cleaning both indoor and outdoor units improves efficiency, but fixing the leak and proper vacuuming before charging is the priority.
The outdoor unit sits in direct sun, how do you handle the high thermal pressure?
We inspect pipes and joints for weakness from repeated heating, repair and insulate weak spots before safe recharging.
