Find the leak first
Refrigerant charging in Al Hazza'iyah
In Al Hazza'iyah, north-east Jeddah, refrigerant charging requires precise diagnosis before topping up. Alrabih's team locates the leak first, repairs it, vacuums the system and charges it to the nameplate 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.

- 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 Hazza'iyah is a developed residential area with modern villas and apartment blocks, many fitted with central or multi-unit split systems operating under higher pressure to cool large spaces. The extreme heat and long runs between outdoor and indoor units in these villas raise the risk of leaks in the copper lines stretched across roofs and walls. Before any charging, the system must be leak-free, or else topping up wastes the refrigerant and energy.
Al Hazza'iyah sits in north-east Jeddah, a district of modern villas and apartment blocks with open spacing between buildings.
Most systems here are central or multi-unit splits, and the long copper runs are the most leak-prone points.
The AC setup in Al Hazza'iyah
- 1
Central system with long copper runs
Modern villas here typically have central AC, and the lines stretched across roofs need regular leak checks, especially in summer.
- 2
Multi-unit splits across floors
Some apartment buildings here use separate splits per flat, and each may need independent refrigerant charging.
- 3
High-pressure units for large spaces
Large villa spaces require higher pressure, increasing the risk of leaks at weak points in the system.
Before the visit
Before our visit in Al Hazza'iyah
- 1
Ensure the team can reach the outdoor unit
Make sure the outdoor unit is in a safe, accessible spot, and let us know if it is far from the entrance or on unsafe ground.
- 2
Arrange building access
Coordinating access with the villa or building guard beforehand speeds up the inspection and charging.
- 3
Tell us about any unusual unit symptoms
If you have noticed weak cooling or unusual noises, let us know before the visit to help us diagnose the leak faster.

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 villas here sit far from the road, how do you bring the vacuum and charging equipment in?
Our team carries portable diagnostic and charging kits and accesses the outdoor unit directly, coordinating the arrival time with the villa owner in advance.
My central unit system needs checking and charging, how long does a visit take?
Leak detection, repair and charging depends on the system size and leak location, so a precise time estimate needs an on-site inspection.
Do copper lines stretched across roofs leak faster due to the extreme heat here?
Yes, the intense heat in Al Hazza'iyah speeds up expansion and contraction in copper, leading to leaks at joints and connections over time.
Do you detect leaks from outside or do you need to open the unit?
We use an electronic leak detector first, and if needed we carefully open the outdoor unit to confirm the exact point, then repair it before vacuum and charging.
