Find the leak first
Refrigerant charging in Al Nuzha
In Al Nuzha, central Jeddah, mixed residential villas and apartment blocks with shops and light commercial activity use AC with long copper runs. Refrigerant leaks quickly affect performance, and Alrabih's team detects the leak, repairs it and charges with 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 Nuzha is a mixed central district of closely spaced residential villas and blocks with shops and commercial activity, situated between northern and central zones. Heat and relative humidity are moderate compared to coastal or very hot northern areas, but long pipe runs between outdoor and indoor units increase leak points. The moderate gaps between buildings make roof and outdoor-unit access relatively straightforward compared to old closely built areas.
Al Nuzha sits in central Jeddah, a mixed district of closely spaced residential villas and blocks with shops and light commercial activity.
Most villas and blocks here use split units with medium-to-long copper runs, and refrigerant leaks are the main issue after two years of use.
The AC setup in Al Nuzha
- 1
Medium to long pipes on exterior walls
Pipes from the roof outdoor unit to indoors run on exterior walls exposed to sun, rain and heat.
- 2
Outdoor units on block and villa roofs
Outdoor units are typically on safe block and villa roofs, making inspection and service straightforward.
- 3
Multiple copper joints needing maintenance
Older villas and blocks may have more copper joints, each a potential leak source needing monitoring.
Before the visit
Before our visit in Al Nuzha
- 1
Locate outdoor unit and confirm safe access
Tell us where the outdoor unit is on the roof and ensure the path to it is safe and hazard-free.
- 2
Provide details about pipes and their routes
Tell us if the pipes are insulated, and how they run from roof to indoors, so we can pinpoint likely leak sites.
- 3
Prepare safe equipment space near the unit
Inspection, vacuum and charging equipment will need a safe, level space close to the outdoor unit.

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 flat is on a high floor; is it hard to reach the outdoor unit?
Outdoor units on apartment blocks are typically on the roof or a safe roofline edge. We confirm safe access and equipment before the visit; safety is paramount.
The pipes run on exterior walls; do sun and rain cause leaks?
Yes, continuous sun, rain and heat exposure stress pipes and joints. Good insulation and annual inspection significantly reduce the problem.
The villa is somewhat old; can pipes shift if the foundation settles?
Foundation settlement can stress pipes and joints, causing leaks. Regular inspection detects any pipe movement early.
After repair and charging, how long can the unit run trouble-free?
A properly repaired circuit easily lasts a year or more without new leaks. Annual inspection helps detect new issues early.
