Find the leak first
Refrigerant charging in Al Wafa
In Al Wafa, east Jeddah, refrigerant charging serves residential flats, clinics and pharmacies in a densely built urban area. Alrabih's team detects leaks with specialist equipment, repairs pipes and joints, then vacuums and charges the circuit to the unit's 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
Al Wafa is a densely built urban area with residential flats, medical clinics and pharmacies along main roads, where AC units are separate or grouped split systems. High heat, dust and moderate humidity accelerate corrosion of copper joints, leaks are common due to intensive operation and environmental stress, and regular checks and correct charging are vital to keep AC running in these critical buildings.
Al Wafa is in east Jeddah, a densely built urban area of residential flats, clinics, pharmacies and shops.
Most units here are separate or grouped split systems per flat or clinic, with outdoor components on balconies or tight roofs.
The AC setup in Al Wafa
- 1
Independent split units per flat
Most flats have independent split units, and clinics and pharmacies also have separate units.
- 2
Grouped units in some buildings
Some multi-storey buildings have grouped outdoor units on a single roof or wall.
- 3
Units on tight balconies and roofs
Outdoor units are typically on tight balconies or limited roofs due to dense construction, which may increase stress on them.
Before the visit
Before our visit in Al Wafa
- 1
Locate the unit and confirm safe access
Tell us where the outdoor unit is (balcony or roof), and ensure our team can reach it safely without risk.
- 2
Prepare unit data and refrigerant type
Get a photo of the nameplate (refrigerant type, capacity, year made) and send it to us before the appointment.

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.
Do clinics and pharmacies need frequent refrigerant charging?
Yes, clinics and pharmacies run their units hard all day, and dust and humidity increase leaks. At least annual checks are essential.
Does dust and high humidity speed up leaks?
Yes, dust accumulates on the outdoor units and humidity speeds copper corrosion. Regular cleaning and checks help prevent leaks.
Are units on tight balconies safe or at risk?
Units on tight balconies face pressure and intense heat, so we inspect them carefully to ensure the joints and pipes are sound.
Does intensive operation pressure affect the circuit?
Intensive operation increases circuit pressure and may reveal early leaks hidden under light use. Regular checks help catch them early.
