Find the leak first
Refrigerant charging in Thuwal
In Thuwal, north of Jeddah, refrigerant charging in modern villas and apartment blocks spread along the coast requires careful assessment of salt and sea humidity damage. Alrabih's team detects leaks with advanced equipment and repairs the lines before charging to the unit's original 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.

- 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
Thuwal is a relatively modern coastal district with detached villas and high-rise apartments overlooking or near the sea, where copper lines face the harshest corrosion from very high salt and sea humidity. Salt air penetrates the copper protective layers faster than inland areas, causing pinhole breaches and very slow leaks hard to spot by eye. Charging without sealing the leak leads to rapid gas loss and compressor strain, so advanced diagnosis and immediate repair are essential.
Thuwal sits on the coast north of Jeddah, a modern residential district of villas and high-rises directly overlooking or very near the sea.
Coastal villas and apartment blocks here have split units with long copper runs, and sea salt causes rapid corrosion leading to frequent slow leaks.
The AC setup in Thuwal
- 1
Split units with salt and humidity exposure
Copper lines in Thuwal are constantly exposed to sea salt and high humidity, making them far more susceptible to corrosion and leaks.
- 2
Outdoor units on exposed coastal roofs
Outdoor units on exposed roofs face salt and humidity directly, rapidly degrading the pipes and joints.
- 3
Temporary protection wrapping for pipes
Some villas wrap their pipes in insulating materials for temporary salt protection, but this protection deteriorates fast and needs regular replacement.
Before the visit
Before our visit in Thuwal
- 1
Identify pipes exposed to salt and humidity
Tell us which pipes run on open roofs or near the sea directly so we give them special attention in the inspection.
- 2
Switch off power before inspection
Turn off power before the team arrives, since leak detection requires the compressor to be completely stopped.
- 3
Provide safe access to roof pipes
Make sure the roof is safe and the team can reach all pipes easily without hazards, and tell us about any barriers or obstacles.

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.
Does sea salt damage the copper AC pipes?
Yes, sea salt corrodes copper very fast, creating tiny pinhole breaches. We use advanced detectors to find these leaks and repair them before charging.
My AC pipes run over the open roof facing the sea directly, is this risky?
Yes, direct exposure to salt and sea humidity speeds corrosion significantly. We inspect regularly and repair any weakness immediately to prevent leaks.
Does the high coastal humidity affect the refrigerant charge?
High humidity does not directly affect the refrigerant, but it speeds up copper corrosion, increasing leak rate if present.
After you fix the leak and charge, how long am I protected from new leaks?
If we seal the leak properly and charge correctly, the sealed circuit does not consume refrigerant. But sea salt may cause new corrosion later, so we recommend regular inspections.
