Find the leak first
Refrigerant charging in Al Shiraa
In Al Shiraa, north Jeddah, refrigerant charging requires careful diagnosis because a sealed circuit does not consume refrigerant by design, a low charge points to a leak that must be fixed first. Alrabih's team locates the leak source, evacuates the system, then charges with the correct refrigerant to the unit's 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.

- 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 Shiraa's villas are mostly modern, with multiple split units and central AC systems for larger spaces, and constant coastal heat and humidity increase the risk of leaks in the copper piping and joints. Detecting a leak in such systems requires advanced equipment and experience, since the outdoor units are often far from the indoor unit across long copper runs.
Al Shiraa sits in north Jeddah, a district of modern villas and apartment buildings with wide spaces between them.
Most Al Shiraa units have long copper runs between the indoor and outdoor units, increasing potential leak points along the line.
The AC setup in Al Shiraa
- 1
Multiple split systems with long copper runs
Villas in Al Shiraa typically have several split units, each potentially needing separate inspection and charging because of the long distances between indoor and outdoor units.
- 2
Central AC systems for larger areas
Some villas and apartment blocks use central AC covering larger areas, meaning larger refrigerant volumes and more complex copper pipe networks requiring careful leak detection.
- 3
Outdoor units on villa roofs or high balconies
Outdoor units are often mounted on roofs or high balconies to catch fresh air, extending the copper line and raising leak risk.
Before the visit
Before our visit in Al Shiraa
- 1
Tell us the exact location of the outdoor unit
Specify if the outdoor unit is on the roof, a balcony, or wall-mounted, as this affects how the team accesses it and how long the leak inspection takes.
- 2
Ensure safe access to the unit and all piping
Check that the path from indoors to the outdoor unit is safe and the team can reach all copper piping points without obstruction, especially if pipes run through tight spaces.
- 3
Provide a safe spot for heavy equipment
Inspection and charging equipment is heavy and sensitive, so provide a safe area near the units to store gear while the team works.

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.
The distance between my indoor and outdoor units is very long, does that cause a leak?
Longer runs mean more joints and potential weak points, which is common in modern villas. We inspect all piping and connections with advanced detection equipment to pinpoint any leak precisely.
Is it enough to just top up the refrigerant without fixing the leak?
No, topping up without fixing the leak wastes it again and strains the compressor. We properly deactivate the circuit, repair the leak, evacuate the system, then charge it with the correct amount.
The coastal air and humidity here are very high, do they corrode the copper pipes?
Yes, high humidity and salt in the air accelerate corrosion of copper and joints, especially if the pipes are exposed. We check the copper condition while inspecting for the leak.
How often should I have my refrigerant inspected?
If your AC is running efficiently, routine inspection is not needed. But if you notice weak cooling or falling performance, contact us immediately to check for a leak before more refrigerant is lost.
