Find the leak first
Refrigerant charging in Al Wisami
In Al Wisami, north-east Jeddah, both central and split AC units need periodic refrigerant checks because any leak cuts performance fast in the hot climate. Alrabih's team locates the leak with specialist tools, repairs it, then evacuates and charges the circuit with the correct type and amount.

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 Wisami is a relatively modern neighbourhood dominated by villas and new flats with wider outdoor space than older areas, and many buildings have central or multi-head split units. Given the high heat and dryness of the north-east sector and the long operating hours, even small leaks in the copper runs or joints develop quickly, and low charge strains the compressor and visibly cuts cooling efficiency.
Al Wisami lies in north-east Jeddah, a modern residential zone of villas and apartment blocks with spacious outdoor areas.
Most villas and flats in Al Wisami have central or multi-head split units, and outdoor units are typically placed on spacious roofs or safe side areas.
The AC setup in Al Wisami
- 1
Central AC systems for three to five rooms
Modern villas in Al Wisami often have one central system serving multiple wings, and full charging requires precise knowledge of the pipe run length and required pressure.
- 2
Multi-head split units in residential flats
New flats often have a split serving two or three rooms, and each indoor head needs separate leak checking during charging.
- 3
Outdoor units on spacious, accessible roofs
Most outdoor units here sit on level roofs away from walkways, allowing safe working and access at any time.
Before the visit
Before our visit in Al Wisami
- 1
Tell us exactly where the outdoor unit is
Be clear about the outdoor unit's location, whether on the roof, side or yard, and ensure the team can reach it safely with measurement and charging equipment.
- 2
Prepare a safe working area on the roof
Ensure railings or safe fixing around the outdoor unit, and let us know if the roof will be wet or slippery on the visit day.
- 3
Switch off power before the visit or alert the team
Either switch the unit off before the team arrives, or brief them immediately on the main circuit breaker's location.

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 I know if my unit's refrigerant is low?
The indoor coil freezes over, or the outlet air is noticeably warmer than usual, and you hear an odd hissing from the compressor. These are leak signs, and the unit needs our team straight away to locate it.
Can you just top up the refrigerant without fixing the leak?
No, because the leak will waste the new refrigerant within days and overstrain the compressor. We must find and fix the leak first, then the charge stays.
Al Wisami gets very hot, does that speed up refrigerant leaks?
Yes, the high heat and dryness of the north-east sector increases circuit pressure, so even a tiny crack in the piping or joints develops a leak faster than in coastal areas.
Are Al Wisami villa roofs safe for installation and servicing?
Most villas here have spacious, safe roofs, but we need to confirm railings or secure fixing before the visit, especially when charging outdoor units.
