Find the leak first
Refrigerant charging in Al Rahmaniyah
In Al Rahmaniyah, east Jeddah, refrigerant charging starts by finding and fixing the leak first. Alrabih's team locates the damage in pipes and joints, evacuates the circuit under vacuum, and charges it with the exact refrigerant type and amount shown on 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.

- 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 Rahmaniyah is a relatively modern residential district with villas and apartment blocks that have reasonable outdoor space, and most units are split or central systems with long copper runs between rooms and bathrooms. Pipes in newer buildings can be punctured by poor installation or slow ground movement, and refrigerant leaks reduce performance gradually before the owner notices. Finding the leak requires specialist testing tools and patience, because some holes are very small.
Al Rahmaniyah sits in east Jeddah, a modern residential district of villas and apartment blocks with adequate outdoor space for copper pipe runs.
Most units here are split or central systems with medium-run copper pipes, and charging work happens on site using professional testing equipment.
The AC setup in Al Rahmaniyah
- 1
Split system with medium copper runs
Most modern villas and blocks in Al Rahmaniyah use split systems with copper runs reaching 15 metres or more.
- 2
Central system with extended ductwork
Some larger villas and newer blocks have central AC with branching copper lines to cool multiple rooms.
- 3
Medium to high capacity units
Al Rahmaniyah units typically range from 2 to 5 tonnes to cover the larger spaces in villas and blocks.

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 unit is running weak, how do I know if there is a refrigerant leak?
Weak output with unusual noise or ice on the outdoor pipes may signal a leak. We use specialist detection equipment to locate the leak precisely before any repair.
Villas here have long pipe runs, does that increase leak risk?
Long pipes do not inherently leak, but most holes occur at joints and bend points. Our team inspects all pipes carefully when searching for the leak.
Humidity in the eastern side is high, does that affect refrigerant charging?
High humidity does not affect the refrigerant itself, but it speeds up oxidation of pipes and joints. We use dry nitrogen during evacuation to remove moisture from the circuit before charging.
What is the price of refrigerant charging in Al Rahmaniyah?
Price depends on the refrigerant type, the amount needed and how hard the leak is to repair. Send a photo of the unit and pipes on WhatsApp for an accurate quote.
