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
Obaid is a sprawling residential district of villas and apartment blocks, smaller and less dense than central Jeddah, but villas here especially suffer repeated refrigerant leaks from poor copper installation or puncture during past maintenance work. Finding and fixing the leak before charging stops the fault returning in just weeks, which matters greatly in older buildings or those with patchy maintenance records.
Obaid lies in South Jeddah's sprawl, a residential zone of scattered villas and apartment blocks spread across wider plots than the city centre.
Most villas and blocks in Obaid have multiple split units, with outdoor units typically mounted on outer walls or roof spaces away from the main entrance.
The AC setup in Obaid
- 1
Multiple split units in single villas
Larger villas in Obaid often have separate splits per wing or bedroom, raising the chance of a leak in one line.
- 2
Outdoor units on distant walls and roof spaces
Villas allow outdoor units to sit far from front facades, meaning longer copper runs more exposed to leaks and corrosion.
- 3
Poor insulation on older lines
Old copper lines in villas built years ago may lack proper insulation, exposing them to moisture and rapid corrosion.
Before the visit
Before our visit in Obaid
- 1
Pinpoint the outdoor unit location
Tell us where the outdoor unit sits (outer wall, roof, side garden) before the visit so we bring the right tools.
- 2
Ensure safe roof or wall access
If the unit is on a high roof or wall, check our team can reach it safely without hazards, and tell us about any obstacles.
- 3
Gather past maintenance invoices if available
If you have records of past charges or repairs, bring them as they help us track repeated leaks and the pattern over time.

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 cools only at night and blows warm by noon, what is that?
That is usually a refrigerant leak causing weak cooling under high heat. We find the leak source first and repair it, then vacuum the lines and charge them to the correct amount.
Villas in Obaid are spread out, how do you reach the outdoor units?
The scattered villas give us better access, and our team can reach the outdoor units on walls and roof spaces more easily than in densely built areas.
Summer heat in Obaid is intense, does that affect the refrigerant charge?
Yes, the extreme summer heat puts greater pressure on the refrigerant and compressors, so charging to the exact nameplate amount preserves performance even in the most intense heat.
The copper lines in my villa are very old, could they leak?
Yes, old copper exposed to direct sun corrodes quickly. On villas we inspect the lines from the outdoor unit all the way to the indoor, pinpointing any leak before charging.
