Find the leak first
Refrigerant charging in Al Quraini'yah
In Al Quraini'yah, south Jeddah, refrigerant charging begins with leak location before refilling. Commercial and light industrial buildings here run more demanding cooling units, and long copper lines are prone to slow leaks.

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 Quraini'yah blends residential flats, small commercial buildings, warehouses and light workshops. The cooling units are more varied: powerful commercial splits, mid-sized central units, and even basic systems for warehouses. Copper lines are often very long to cover larger areas, increasing potential leak points. Commercial and industrial use is heavier and longer hours, exposing lines and joints to more stress.
Al Quraini'yah sits in south Jeddah, a mixed district of residential, commercial buildings and warehouses.
Units here are varied: powerful commercial splits and central systems, with long copper lines that multiply potential leak points.
The AC setup in Al Quraini'yah
- 1
Powerful commercial splits in shops
Commercial shops and offices have powerful split units with outdoor boxes on roofs or external walls.
- 2
Central units in warehouses
Warehouses and workshops rely on central units or basic distribution systems across the space.
- 3
Long copper lines along facades and roofs
Lines run long distances from outdoor to indoor units, exposed to expansion, contraction and leaks.
Before the visit
Before our visit in Al Quraini'yah
- 1
Specify all outdoor and indoor unit locations
If you have multiple units or a complex system, tell us the exact location of each outdoor and indoor unit before the visit.
- 2
Confirm access to the roof and external walls
The team needs safe access to lines on the roof and external walls to inspect and repair leaks.
- 3
Disconnect power or locate the breaker
Power must be disconnected from all units before inspection or repair, so tell us exactly where all breakers are.

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.
My commercial shop runs 12 hours a day and the AC is not cooling like it used to, how do I know if there is a leak?
Heavy use reveals leaks faster. If cooling drops noticeably in a week or two, a leak is likely. Our team checks pressure, lines and joints carefully to find it.
The pipes in my shop run a long distance from outside to inside, does this increase the risk?
Yes, each extra metre of line adds a potential leak point. Long lines need strong foam insulation and regular inspection at joints and weak spots.
My warehouse is always cold and the AC runs under heavy load, does this speed up leaks?
Yes, continuous heavy use raises pressure on lines and joints, hastening small leaks. Regular maintenance and inspection reduce problems.
I had refrigerant added a month ago and it dropped again, was the leak not properly fixed?
If a leak was present and not fixed before filling, the refrigerant will drop again. Our team locates the leak first using pressure checks and dye injection, then repairs it before any refill.
