Find the leak first
Refrigerant charging in Al Ajwad
In Al Ajwad, east Jeddah, with its dense residential blocks, commercial shops and small factories, refrigerant loss from leaks needs professional diagnosis because piping may run through varying environments from cool to hot. Alrabih's team finds the leak precisely, repairs it, evacuates the system, and charges to the correct refrigerant type.

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 Ajwad is a mixed residential and commercial area with multi-storey blocks, ground-floor shops and small factories, where copper piping may pass through areas of rapidly changing heat and humidity, exposing it to varying stress. This environmental variety increases leak risk, especially during seasonal transitions, and inspection and repair may take longer as the team traces piping through complex spaces.
Al Ajwad is a mixed-use district east of Jeddah, combining residential blocks, commercial shops and small manufacturing.
Most units here are splits in flats and shops, with piping extending through external spaces or tight passages between closely built blocks.
The AC setup in Al Ajwad
- 1
Split units in flats and above shops
Mixed-use blocks here have residential flats above ground-floor shops, each with separate split units.
- 2
Piping through tight external passages
Piping often runs through tight external gaps between closely built blocks or across shared roofs.
- 3
Cooling units in shops and small factories
Some shops and small factories have higher-capacity units or multi-unit systems to cool larger areas.

Tell us about nearby heat and vibration sources
Let us know if there are factories or strong heat sources near your pipes, so we can plan inspection and determine the best repair solution.
- 2
Map the piping route and obstacles
If piping runs through tight gaps or shared roofs, describe the route and any obstacles that might block safe access.
- 3
Coordinate with residents or neighbouring shop owners
If piping crosses a shared roof or passes a neighbouring shop, we may need neighbouring residents' or shop owners' approval to access it.

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.
Our shop is next to a factory, does this affect refrigerant leaks?
Heat and vibrations from adjoining factories can stress your copper piping and increase leak risk, especially if pipes run near shared walls.
Our pipes run very close to a strong heat source, is that dangerous?
Yes, direct heat can weaken pipes over time and accelerate leaks, and we may need to add extra insulation or reroute pipes away from the heat source.
Our flat is in an older building with visibly cracked pipes, is that why it is leaking?
Cracked pipes may be from age or stress, and we use a gas detector to pinpoint leaks precisely, possibly needing to replace part of the piping or the entire run depending on condition.
After repair and charging, how long will the refrigerant stay in the system?
If the leak is properly repaired and all joints are sealed, the refrigerant stays in the closed circuit for a very long time with no loss, and any later drop signals a new leak.
