Find the leak first
Refrigerant charging in Al Nur
In Al Nur, north Jeddah, many AC units suffer slow refrigerant leaks that gradually reduce cooling. Alrabih's team locates the leak with specialist equipment, repairs it, then evacuates and charges the circuit with the correct refrigerant type to the unit's nameplate.

Signs the charge is low
- 1
Weak cooling and a compressor that runs on
The unit runs for hours without bringing the temperature down, or cools very slowly. This is usually the first sign the charge is low and the circuit can no longer move heat efficiently.
- 2
Frost on the pipes or evaporator coil
Ice on the thin pipe or on the evaporator coil points to low refrigerant pressure. Continued running can damage the coil. Where the frost forms helps the technician narrow down the problem area.
- 3
A refrigerator or cold room that will not hold temperature
In commercial or industrial refrigeration equipment, a rising cabinet temperature means stock at risk. Low refrigerant is one possible cause, and confirming it needs pressure readings and a circuit check on site.
Who it's for
Your window or portable unit cools slowly
We check circuit pressure, locate and repair the leak, then vacuum and charge to the type shown on your unit's nameplate.
Ask on WhatsAppYour cold room or commercial fridge will not hold temperature
We measure pressure, identify why the cabinet temperature is rising, repair any leak found, then charge to the correct refrigerant type for that unit.

- Vacuum and tightness test
- Charge to nameplate refrigerant
- Run test and performance check
How we work
How we work
- 1
Inspect and locate leak
The technician measures circuit pressure and checks joints and components that corrode in Jeddah's humid, salty air, pinpointing the leak before any other step.
- 2
Repair the leak
The technician repairs the leak point, whether a loose joint, a cracked pipe or corrosion in part of the circuit. The unit is not charged until the repair is confirmed tight.
- 3
Vacuum and pressure test
The circuit is evacuated with a vacuum pump to remove air and moisture, then the reading is watched to confirm pressure holds before refrigerant is introduced.
- 4
Charge and run
The unit is charged to the nameplate type and amount, then run and checked for proper performance on site before handover.
Fix the leak or just top it up?
| Alrabih | The usual way | |
|---|---|---|
| The leak | Found and fixed first | Often ignored |
| Vacuum | Before every charge | Sometimes skipped |
| Refrigerant type | As the nameplate states | May be mixed or swapped |
| Compressor | Protected by correct charge | Worn by wrong charge |
| Refrigeration equipment | AC, fridges and cold rooms | Usually AC only |

What sets this district apart
Al Nur, Al Rabee and Al Najmah are relatively newer residential districts with mostly split units in flats and villas, but many buildings are a decade or older, so the copper pipe runs are beginning to corrode and leak. Slow leaks are common here because the outdoor lines face high heat and temperature swings, so early leak detection saves customers the cost of repeated recharging.
These districts sit in modern north Jeddah, expanding residential areas with relatively newer apartment blocks and distributed split units.
Most split units here were installed ten years or more ago, and sun-exposed copper pipe runs begin to slow-leak after time.
The AC setup in Al Nur
- 1
Split units with exposed copper runs
Most units here are split indoor-outdoor pairs with visible copper lines exposed to sun and air.
- 2
Long distances between indoor and outdoor units
Some flats are far from the exterior wall, requiring longer copper runs that increase leak risk at the joints.
- 3
Uninsulated copper lines in some cases
Some older installations lack thermal insulation on the lines, exposing them to faster corrosion.
Before the visit
Before our visit in Al Nur
- 1
Ensure the team can reach the outdoor unit
The outdoor unit is usually on the exterior wall of the flat or villa; confirm the team can access it safely.
- 2
Prepare photos of the unit and lines
Send us a photo of the outdoor unit and copper lines before the visit so we can prepare the right equipment.

Tell us the current refrigerant type
If you know the current refrigerant type (such as R22 or R410A), tell us before the visit to avoid any mix-up during charging.

FAQ
Questions about Refrigerant charging
Can you just add refrigerant without looking for the leak?
A sealed refrigerant circuit does not consume refrigerant. A low charge means there is a leak somewhere. Adding refrigerant without finding and repairing that leak brings the same fault back quickly and can damage the compressor. The correct sequence is always to locate the leak, repair it, pull a vacuum on the circuit, and then charge to the type and quantity shown on the unit's nameplate.
Where does refrigerant leak in commercial refrigeration equipment?
The most common points are expansion fittings and restrictions on the liquid line, flare joints at the evaporator and condenser, and service valves where the rubber seals have aged. In commercial refrigeration, old copper pipe welds weakened by continuous compressor vibration are also a frequent source. The exact location is found during the site inspection.
Does the refrigerant type affect how the unit performs?
Yes. Every unit is designed for a specific refrigerant type with defined operating pressures and heat transfer properties. Using a different type changes those pressures and can either overload the compressor or reduce cooling output. For this reason the unit is always charged with the exact type shown on its nameplate and no substitute is used.
Is the charging work different for a home AC unit and a commercial refrigerator?
Yes, they differ in several ways. Commercial refrigeration units operate at pressures and with refrigerant types distinct from those in air conditioners, and their target temperatures are much lower. The pipe circuits are also longer and often include multiple distributors and valves that require careful inspection before vacuuming and charging. The nature of each circuit determines the procedure.
Is the charging work different for a home AC unit and a commercial refrigerator?
The core steps are the same: locate the leak, repair it, vacuum the circuit, then charge to the nameplate type. Commercial refrigeration units sometimes have additional valves and components that require a different inspection approach. What each unit needs is determined by the technician on site after pressure readings and a circuit check.
How do you tell a slow leak from a weak charge?
We use specialist leak detection equipment to confirm if a leak exists before any charging. If we find one, we repair it first; otherwise we simply evacuate and charge the circuit to spec.
Our copper lines run on the exterior wall, do they corrode from sun exposure?
Yes, direct sun and high heat speed corrosion in exposed copper lines over time, especially in north Jeddah where heat is intense.
Is it safe to keep recharging without fixing the leak?
No, recharging without fixing the leak wastes refrigerant and strains the compressor. We repair the leak first to save costs and protect the unit long term.
How long does leak detection, repair and charging take?
The time depends on where the leak is and how difficult the repair. We will give you details on the first visit when we inspect the unit.
