Find the leak first
Refrigerant charging in Al Zumurrud
In Al Zumurrud, north Jeddah, most modern villas need refrigerant charging when cooling drops or a slow leak develops. Alrabih's team locates the leak with a sensitive detector, repairs it, then vacuums and charges the unit to its nameplate 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 Zumurrud is a relatively new residential district of villas with central or multi-split cooling systems, and the long copper runs in concrete foundations make units prone to slow leaks over time. Many owners don't understand the difference between topping up and fixing a leak, so we explain the steps before any work starts.
Al Zumurrud lies in north Jeddah, a modern villa district with wide outdoor spaces and long copper runs between indoor and outdoor units.
Most leaks in Al Zumurrud villas occur at valves or copper joints in the foundation due to minor soil settlement and seasonal vibration.
The AC setup in Al Zumurrud
- 1
Multi-split systems in single villas
Most modern villas have one or two outdoor units serving several indoor zones, so a leak may affect one or more zones depending on where it occurs.
- 2
Long copper runs buried in the foundation
The copper runs between outdoor and indoor units often pass under ground or through the concrete foundation, so leak detection needs a sensitive instrument.
- 3
Central AC systems in larger villas
Larger villas may use a central system distributed to rooms via ducts, and leaks here are harder to pinpoint because of the many connections.
Before the visit
Before our visit in Al Zumurrud
- 1
Ensure the outdoor unit is accessible
The outdoor unit is usually in the yard or on a partial roof, so confirm the access path is clear and safe before the visit.
- 2
Locate any visible copper runs
If any copper runs are visible on walls or in the yard, point them out to the team before inspection to speed up leak detection.
- 3
Clear space around the outdoor unit
The team needs free movement around the outdoor unit to connect detection and charging equipment, so clear away nearby objects and plants.

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 unit cools but weakly, is the refrigerant always low?
Usually yes, but the cause is often a slow leak you cannot feel. We detect the leak first with a sensor, then repair it before adding fresh refrigerant.
These villas have long copper runs, do they leak more?
Yes, longer runs and multiple joints are more prone to leaks because of vibration and seasonal shifts in newly built homes.
Jeddah's coastal humidity is high, does it affect the refrigerant's performance?
High humidity and coastal heat raise the working pressure on the unit, so charging to the exact nameplate amount keeps performance and efficiency stable.
After we repair the leak and charge, how long should the refrigerant level stay stable?
A properly sealed circuit loses no refrigerant. If cooling drops again in a few weeks, the leak was not fully repaired, which means a second visit to investigate.
