Find the leak first
Refrigerant charging in Abhur Al Shamaliyah
In Abhur Al Shamaliyah, north Jeddah, modern villas and homes rely on central AC with a sealed refrigerant circuit. When performance drops, there may be a leak, and charging without fixing the leak first wastes refrigerant and strains the compressor.

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
Abhur Al Shamaliyah is a modern residential area of spacious villas and houses on large plots, served by central AC distributing air through hidden ducts in ceilings and walls. The copper pipes of the sealed circuit are usually buried underground or inside walls, and a slow leak may not show until weeks of declining performance. Our team finds the leak with an electronic detector and pressure-tests the circuit before final charging.
Abhur Al Shamaliyah is in north Jeddah's residential sector, a modern area of large villas and open green spaces.
Most homes here have central AC with one outdoor compressor serving multiple zones, and the copper lines are fully concealed.
The AC setup in Abhur Al Shamaliyah
- 1
One central compressor serving multiple zones
Most modern villas here have a single outdoor compressor connected by copper lines to multiple indoor units throughout the home.
- 2
Copper lines buried beneath the foundation
Lines are usually hidden underground during construction, making any leak hard to detect without a specialised electronic tool.
- 3
Multiple wall-mounted indoor units
Villas typically have multiple wall units across different rooms, all connected to the same sealed circuit.
Before the visit
Before our visit in Abhur Al Shamaliyah
- 1
Locate the outdoor unit clearly
Tell us exactly where the outdoor unit sits in the garden and whether there are fences or barriers around it.
- 2
Provide a photo or drawing of the pipe routes if available
If you have the building plan or a photo of the pipe routes before they were buried, this saves time in locating the leak.
- 3
Ensure the team can access the outdoor area
Check that the team can reach the outdoor unit and the surrounding area with their tools without obstruction.

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.
How do you confirm a leak before charging refrigerant?
We use a sensitive electronic detector to find any small leak in the pipes and connections. After sealing the leak, we vacuum the circuit fully and then charge it to the type and amount on the nameplate.
The copper lines are buried underground, how do you access them?
We usually trace the pipes from the outdoor unit and locate visible connection points. If the lines are fully buried, we ask for the building plan or architectural drawing to map the route before the visit.
The area gets very hot in summer, does this increase leak risk?
Yes, intense heat and repeated expansion and contraction put stress on the pipes and joints, especially buried lines. This is why we recommend an annual circuit check before the summer season.
After charging, how long does the refrigerant stay in the circuit?
In a properly sealed circuit, refrigerant remains indefinitely. If there is even a slow leak, the charge will diminish gradually and performance will decline again.
