Find the leak first
Refrigerant charging in Al Tilal
In Al Tilal, east Jeddah, refrigerant charging requires genuine leak detection before charging, because eastern dust and sand clog pipes and accelerate escape. We find the leak first, clean the lines, then vacuum the circuit and charge it correctly.

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 Tilal is a relatively modern residential area in the east with villas set back in gardens and spread-out blocks, but constant exposure to easterly winds and dust means air filters and copper lines clog quickly. This strains the compressor and makes any existing leak develop faster, so our testing includes cleaning lines before detecting fine leaks.
Al Tilal is in east Jeddah, a modern residential area of villas and spaced buildings constantly exposed to easterly dust and wind.
Eastern dust clogs outdoor filters quickly, and copper lines can clog from inside if not cleaned regularly before charging.
The AC setup in Al Tilal
- 1
Split per villa with long run
Most Al Tilal villas have outdoor units set away from the main building, and the long run needs comprehensive leak testing along its entire length.
- 2
Split units for flats with grouped outdoor units
Modern Al Tilal blocks sometimes group outdoor units in one roof or side area, making collective access easier for testing.
- 3
Units on open roofs exposed to dust
Open roofs in Al Tilal face direct eastern wind and dust, so regular filter and line cleaning is essential before any charging.
Before the visit
Before our visit in Al Tilal
- 1
Tell us the side gate and entry location
If the villa has a side gate or alternate access to the outdoor unit, let us know beforehand so we can anticipate the easiest route.
- 2
Check that outdoor filter is relatively clean
Before the visit, clean or check the outdoor filter, because heavy dust can mask fine leak detection.
- 3
Have distilled water and safe working space
Evacuation and charging need distilled water and power, so confirm both are available near 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.
Eastern dust gets into the unit; does that cause refrigerant leaks?
Dust itself does not cause leaks, but the extra strain from blockages accelerates any existing leak, so we clean the lines before testing.
Outdoor units are set back on villas; is access difficult?
Yes, most Al Tilal villas have gardens and space, and we can reach outdoor units easily via side gates.
Easterly winds are strong and carry dust; does this affect charging?
Wind itself does not affect the charging process, but dust may enter during service, so we clean the lines thoroughly beforehand.
Villa copper runs are long; are there weak leak points?
Longer runs mean more joints, and each is a potential leak point, so we test them all before charging.
