Find the leak first
Refrigerant charging in Al Majd
In Al Majd, north-east Jeddah, refrigerant charging begins with a thorough leak check before any top-up. Alrabih's team locates the leak, repairs it, then evacuates and charges the circuit 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.

- 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 Majd is a relatively modern district of spacious villas and large plots where central and split AC units are widely installed. The outdoor units here operate in intense heat and direct sun for long hours, which stresses the circuit and accelerates leaks in the copper connections. Leak detection requires skill in tracing hairline cracks in pipes and joints under extreme heat.
Al Majd lies in north-east Jeddah, a district of modern villas with spacious outdoor areas and central or split AC systems.
Most outdoor units here are roof or wall-mounted in direct sun exposure, and suffer faster leaks due to thermal expansion.
The AC setup in Al Majd
- 1
Central AC with outdoor compressor units
Most modern villas in Al Majd have central AC systems with large outdoor compressor units mounted on roofs or walls.
- 2
Multi-zone split systems
Many large villas have multiple indoor units connected to one outdoor compressor, so leaks in the main copper lines affect all rooms.
- 3
Long exposed copper runs
Copper pipes run across roofs and exterior walls in direct sun and heat, experiencing daily thermal cycling.
Before the visit

Confirm safe roof access
If the outdoor unit is on the roof, ensure a safe ladder, staircase or platform is available before the visit day.

Identify suspected leak location
If possible, notice any uneven cooling between rooms or any unusual sounds from the unit, and tell us before we inspect.

Prepare unit nameplate information
Take a photo of the outdoor unit's nameplate showing the refrigerant type and capacity, which speeds up our inspection and charging.

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 villa AC loses cooling quickly in Al Majd's hot summer, is this a leak?
Yes, intense heat and direct sun on the outdoor unit causes thermal expansion that cracks pipes and joints. We detect leaks with precision sensors and repair the cracks before charging.
The outdoor unit is on the roof, how do you reach it for inspection and repair?
We need safe roof access and agree on safety arrangements beforehand. Ensure there is a ladder, staircase or safe platform available before the visit.
Copper pipes expand in this heat, does this cause continuous leaks?
Thermal expansion puts joints under constant stress, and hairline cracks widen with thermal cycles. Repairing the leak includes inspecting all joints and connections to ensure the repair holds before charging.
How much does refrigerant charging cost if there is a leak in the villa?
The cost depends on the unit size, capacity, copper pipe run length, leak location and repair difficulty. Send a photo of the unit on WhatsApp and we will provide a detailed quote.
