Find the leak first
Refrigerant charging in Al Marsa
In Al Marsa, south Jeddah, refrigerant charging requires careful leak detection before any top-up, because the salt-laden air near the sea accelerates joint corrosion. We find and fix the leak first, then vacuum the circuit and charge it correctly.

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 Marsa is a coastal area near the sea, with apartment blocks, hotels and shops exposed to humid, salt-laden air that speeds corrosion of joints and copper lines. This means a leak may not be obvious at first but develops quickly due to oxidation, so our detection focuses on catching pinhole leaks and slow escapes early before they damage the compressor further.
Al Marsa lies on the coast south of Jeddah, a seafront district of apartment blocks, hotels and commerce with high humidity and salt content.
Outdoor units in Al Marsa are directly exposed to salt air and humidity, and leak-related corrosion calls for specialist detection and prompt repair.
The AC setup in Al Marsa
- 1
Coastal split units exposed to salt
Outdoor units in Al Marsa face direct salt air exposure, and corrosion-related leaks require continuous monitoring and swift repair.
- 2
Central units in hotels and large blocks
Hotels and large blocks in Al Marsa run central systems with multiple compressors, and leaks can occur in any branch of the main system.
- 3
Long copper runs from roof to units
Most flats and hotel units here have long runs from the rooftop unit, so leak testing covers the entire length and all floor-level joints.
Before the visit
Before our visit in Al Marsa
- 1
Confirm safe access to roof and unit
Roofs near the sea can be slippery sometimes, so ensure the path is safe before the appointment and let us know of any obstacles.
- 2
Have distilled water and test equipment ready
Evacuation needs distilled water, and we may need safe electrical access near the outdoor unit.
- 3
Tell us if the unit is near salt sources or spray
If the unit is near direct salt spray or heavy sea salt, tell us beforehand so we can bring extra protective gear.

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 outdoor unit rusts quickly; does that cause refrigerant leaks?
Yes, corrosion and oxidation from salt air create pinhole leaks in pipes and joints, and our detection specifically targets these weak points before charging.
Can you easily reach outdoor units close to the seafront?
Yes, most units in Al Marsa are on roofs or seafront-facing facades, and our team is used to working in this salt environment.
Humidity and salt speed up leaks; how do you handle this?
We use highly sensitive detection equipment to catch slow leaks early, and repair corroded joints with rust-resistant materials before charging.
The copper line run from unit to flat is long; does this affect the charging?
The length itself does not affect charging, but any leak can be anywhere along the run, so we test the entire length before charging.
