Find the leak first
Refrigerant charging in Harat Al Yemen
In Harat Al Yemen, downtown Jeddah, low refrigerant in AC units and commercial fridges requires finding and sealing any leak first before recharging. Alrabih's team locates the leak source, vacuums the circuit, then charges the system to the nameplate type and amount.

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
Harat Al Yemen is a dense old district packed with shops, storage units and closely built residences, hosting many commercial display fridges, freezers and central AC systems in shops, restaurants and bakeries. The high humidity and dust near the souk accelerates pipe and joint corrosion, raising the risk of leaks in these units. Accurate leak detection and repair demands deep knowledge of different circuits, and charging only after confirming the system is sound protects the compressor from damage.
Harat Al Yemen sits in the heart of Jeddah's historic downtown, a densely commercial district of shops, storage, and old popular markets.
Most refrigeration units in Harat Al Yemen are commercial display fridges and central AC systems in shops and restaurants, demanding high precision in leak detection.

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 handle refrigerant leaks in commercial fridges in Harat Al Yemen?
We locate the leak source with sensitive detection equipment, repair the leak first, then vacuum the circuit and recharge to the original type and amount.
Does high humidity and dust near the markets cause refrigerant leaks in AC systems?
Yes, the high humidity and dust near the souk accelerate corrosion of pipes and joints, raising leak risk. Regular inspection helps catch it early.
Do you top up refrigerant without fixing the leak first?
No, topping up without repairing the leak wastes refrigerant and strains the compressor. We repair first, then vacuum and recharge.
Does low refrigerant affect a shop's display fridge and freezer performance?
Yes, low refrigerant reduces cooling efficiency and makes the compressor work harder, risking damage. That is why leak detection and repair must be swift.
