Find the leak first
Refrigerant charging in Al Nada
In Al Nada, east Jeddah, leak detection comes before refrigerant charging. A sealed circuit does not consume refrigerant, so any drop in charge indicates a leak that must be repaired before refilling.

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.

- 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 Nada is a growing residential district with diverse villas, modern apartment blocks and some commercial facilities. The coastal location, intense summer heat and high humidity create constant stress on copper pipes and soldered joints, causing gradual hairline cracks and slow leaks. Our team uses highly sensitive electronic detection to find the leak, repairs damaged pipes and joints, then recharges the exact refrigerant type and amount for the unit.
Al Nada sits in east Jeddah, a growing residential district with a mix of villas, blocks and open spaces.
Refrigerant leaks in Al Nada are usually slow and gradual at joints and valves, not in the pipes themselves.

Before the visit
Before our visit in Al Nada
- 1
Describe the unit locations clearly
Tell us where the indoor unit is (which room, which wall) and where the outdoor one is (roof, balcony, exterior wall) so we can assess pipe length and potential leak points.
- 2
Identify the electrical breaker location
Testing and repair require shutting off power. Know in advance where your unit's breaker is or tell us its location.
- 3
Prepare safe and easy access
If the unit is on a roof or high spot, ensure a safe ladder is available. If it is in a shop, coordinate the visit time with the owner.

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.
My unit is getting older, is it normal to lose refrigerant every year or two?
No, even older units have sealed circuits that do not consume refrigerant. Yearly loss means a persistent leak, possibly in an aging joint or faulty valve. We detect it with sensitive equipment and fix it permanently.
Al Nada is close to the sea, does the moisture speed up leaks?
Yes, coastal moisture causes joints and valve metals to corrode faster. At least an annual system check before summer catches slow leaks early.
Do exposed refrigerant pipes need extra protection from the sun?
Exposed pipes expand quickly under direct heat, stressing the joints. You can add simple foam insulation to the pipes, but annual inspection is more important to catch leaks early.
How do I know exactly when I need a refrigerant top-up?
Signs of low refrigerant include weak cooling, frost forming on the indoor unit, or strange compressor noise. Do not wait, call us right away. We inspect the system and find the leak before any new charge.
