Charged right, not just topped up
Split AC refrigerant charging in Al Sahil
In Al Sahil, south Jeddah, split AC units need refrigerant charging after locating and fixing any leak, because topping up alone without finding the cause brings the problem back 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 Sahil's southern districts stretch along the Red Sea coast with modern villas and medium-rise apartment blocks set on open plots, but the high humidity and salt air close to the shore corrode the copper lines faster than inland areas. Finding the leak first, then vacuuming and precise charging is essential because a slow leak may not show in a quick check but returns within weeks.
Al Sahil lies on Jeddah's southern beachfront, a district of relatively modern villas and residential blocks under direct exposure to Red Sea humidity and salt air.
Most split units here are mounted on exterior walls directly exposed to sea air and high humidity.
The AC setup in Al Sahil
- 1
Split system with long lines on exterior walls
Villas and blocks here have open outdoor spaces, so copper lines run directly across exterior walls exposed to sea air.
- 2
Multiple split units in a single villa
Some modern villas have two or more split units, each needing separate charging and independent leak inspection.
- 3
Relatively short lines in apartment blocks
Apartment blocks here need shorter runs between indoor and outdoor units, but direct salt and humidity exposure remains the main challenge.
Before the visit

Provide photos of the outdoor unit and lines
Send photos of the outdoor unit and copper lines via WhatsApp before the visit so we can assess corrosion and likely leak points.

Know the unit's original refrigerant type
Check the unit's nameplate or owner's manual for the correct refrigerant type and charge amount, and have this information ready 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.
Why does my split cool only at night and not during the day?
Often a slow refrigerant leak or compressor fault is to blame, and may not show in a quick check. We locate the leak with specialist detection tools and fix it before charging to keep the problem from returning.
Does the coastal humidity affect the refrigerant lines?
Yes, high humidity and salt air near the shore speed up corrosion of the copper lines outside, causing a slow leak that may go unnoticed at first but worsens over time.
How do you confirm the leak is fixed before charging?
We use electronic detection equipment to pinpoint the leak's exact location, repair the damaged line or fitting, then clean and vacuum the line to remove air and moisture before charging with the correct refrigerant type.
Do you inspect the outdoor unit on the exterior wall?
Yes, we check the outdoor unit and exposed lines for corrosion and damage first, and confirm it is safely mounted to the wall so it will not shift in coastal winds.
