Find the leak first
Refrigerant charging in Al Baghdadiyah Al Sharqiyah
In Al Baghdadiyah Al Sharqiyah in central Jeddah, refrigerant charging requires locating the sealed circuit's leak first. Alrabih's team finds the leak source, repairs it, then evacuates air and moisture and recharges the unit to the nameplate specification.

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.

What the work covers
- Pressure check and leak location
- Leak repair before charging
- 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 Baghdadiyah Al Sharqiyah is a relatively modern residential district of multi-storey blocks and villas, with most units running continuously through Jeddah's long summer. When refrigerant drops in a split or central unit, the only cause is a leak in the copper pipes or joints, and topping up without fixing it wastes the charge again and strains the compressor. Thorough leak detection and repair must come first, before any new charge.
Al Baghdadiyah Al Sharqiyah is in central Jeddah, a modern residential district of multi-storey blocks and villas with both central and split AC systems.
Central and split systems dominate here, with leaks in the longer copper runs typically occurring at joints or circuit branches.
The AC setup in Al Baghdadiyah Al Sharqiyah
- 1
Split systems in villas and flats
Most villas and flats have individual split units per room or zone, with leaks occurring in the pipes running between indoor and outdoor units.
- 2
Central AC in larger apartment blocks
Larger apartment blocks run central systems with long refrigerant runs and distributed piping, so the leak can be far from the main unit.
- 3
Multiple copper joints in circuit branches
When one circuit feeds multiple indoor units, the joints at branch points are the most leak-prone locations.
Before the visit
Before our visit in Al Baghdadiyah Al Sharqiyah
- 1
Tell us the location of indoor and outdoor units
Specify where the outdoor unit and indoor units are located and how many indoor units share the circuit to assess pipe length and joint count.
- 2
Ensure access to the outdoor unit
The outdoor unit may be on the roof or balcony, so confirm the team can safely reach it with their equipment.
- 3
Prepare electrical switches and water drainage
Ensure the unit is disconnected from power before the visit, and confirm where condensation drainage from the pan flows easily.

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 confirm the leak is sealed before charging?
We use specialised leak detection equipment to pinpoint the leak, repair it with brazing or joint replacement, then verify the seal before charging.
My central AC pipes are long, does that mean more leaks?
Longer copper runs have more joints, and leaks can occur at any of them, but a full inspection pinpoints the exact location.
Does Jeddah's long summer affect how fast the refrigerant leaks?
Higher pressure inside the circuit from the heat accelerates the leak, so maintaining a proper seal is even more critical in Jeddah's extended summer.
Do I need air evacuation after the leak repair?
Yes, after sealing any leak we evacuate all air and moisture from the circuit with a specialised vacuum pump before charging.
