Find the leak first
Refrigerant charging in Al Marj
Refrigerant charging in Al Marj requires precise leak detection and repair before charging, since a healthy sealed circuit does not lose refrigerant. Charging without leak detection wastes both the refrigerant and money.

- Vacuum and test
- Accurate charge

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 Marj is a relatively modern neighbourhood in the north-east, dominated by mid-size residential blocks with moderate and sometimes tight outdoor space. Most systems here are dual or triple splits from one outdoor unit, with medium-length copper pipes. Coastal proximity and humidity increase corrosion risk at joints and pipes, especially for outdoor units mounted on narrow facades or small balconies.

Most units here are dual or triple splits sharing one outdoor unit, with medium copper runs through building walls or balconies.
The AC setup in Al Marj
- 1
Dual or triple splits from one outdoor unit
Most Al Marj blocks run two or three indoor units from a single outdoor unit via shared copper piping.
- 2
Copper piping through building walls
Pipes often run through building walls from the outdoor unit on the balcony to indoor units, or along external facades.
- 3
Outdoor units on limited balconies
Balconies in Al Marj are typically narrow, so the outdoor unit sits directly on it with refrigerant piping connected.
Before the visit
Before our visit in Al Marj
- 1
Tell us exactly where the outdoor unit sits
Specify if the unit is on a front or rear balcony or external wall, and whether access is safe and straightforward.
- 2
Provide the unit's nameplate information
Look for the data plate on the outdoor unit with model, refrigerant type and capacity, or send photos from all angles.
- 3
Ensure pipes are visible and accessible
Check that copper pipes from outdoor to indoor units are visible for inspection for rust or leaks, and alert us to any 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.
One of my indoor units is losing cooling, is there a leak in my piping?
It could be a leak in that unit's piping or at the main junction. We check all copper pipes and joints, repair the leak, then recharge the circuit with the correct refrigerant.
The outdoor unit is on a tight balcony, does that cause leaks?
Tight balconies limit airflow around the unit, raising heat and pressure, which speeds corrosion at joints. Regular pipe inspection is essential.
We are close to the sea, does the salt air affect the refrigerant or pipes?
Yes, salt accelerates copper and metal joint corrosion, potentially causing slow leaks. Wrapping pipes with insulation and rust-resistant sealant reduces risk.
After charging, how long does the refrigerant charge last?
If we repair the leak properly, the refrigerant lasts many years. A sealed circuit does not naturally consume refrigerant, so early recharging means a new leak.
