Find the leak first
Refrigerant charging in Al Ajawid
In Al Ajawid, south Jeddah, dense residential blocks and housing complexes rely on multiple AC units where leaks may go unnoticed until cooling drops. Alrabih's team uses advanced leak detectors to find even the tiniest escape, fixes it fast, then charges precisely to spec.

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.

What the work covers
- Pressure check and leak location
- Leak repair before charging
- 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 Ajawid is a dense residential zone with high-rise apartment blocks and unified housing complexes, most with separate split units per flat or a shared central AC serving multiple units. The south location means strong heat and relative dryness, and rapid dust buildup on outdoor units increases system pressure. Leaks may start small and go unnoticed for weeks, but in hot, dry conditions they develop fast and visibly cut performance, making regular servicing essential to avoid major repair bills.
Al Ajawid sits in south Jeddah, a dense residential zone with high-rise apartment blocks and organised housing complexes.
Most Al Ajawid flats have separate or shared-system split units, with outdoor units mounted on side walls or modest-sized balconies.
The AC setup in Al Ajawid
- 1
Shared central system with multiple branches to flats
Many blocks have one system serving three to six flats via separate branches, and charging demands complete knowledge of each run and its correct pressure.
- 2
Separate split per flat, sometimes shared outdoor unit
Some flats have separate indoor heads but share one outdoor unit, increasing leak risk in shared connections.
- 3
Outdoor units on tight walls or modest balconies
Outdoor units are mounted on narrow walls or modest balconies due to high population density, demanding efficient technical work.
Before the visit
Before our visit in Al Ajawid
- 1
Coordinate with building management about the visit
Alert building management in advance about the visit time and expected duration, especially if servicing will interrupt service to multiple flats.
- 2
Locate the outdoor unit and main circuit breaker
Tell us exactly which wall or balcony holds the outdoor unit, and locate the main circuit breaker for the central system.
- 3
Ensure safe access and minimal obstruction
Check the balcony or wall is free of obstacles blocking access, and alert us to any safety barriers or restrictions.

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.
A residential block with shared central AC, how do you check for leaks in a complex system?
We check each branch of the main run with an electronic detector, isolating each unit separately if needed to pinpoint the leak precisely.
Multiple flats share one system, how do you charge without disrupting the others?
We plan the visit with building management in advance, and carry out charging swiftly and accurately to minimise service disruption.
Do dust and heat in Al Ajawid speed up leaks?
Yes, strongly. Dust accumulates fast on the condenser and raises pressure, and sustained heat speeds copper joint corrosion. Six-monthly checks beat annual ones here.
Al Ajawid's balconies and walls are tight, can you safely work on outdoor units?
Yes, our team is used to tight spaces. We work carefully and coordinate with neighbouring flat occupants if we need extra room.
