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 Thaghr is a coastal area close to the sea, home to modern villas, apartment blocks and tourist facilities. High salinity and intense humidity accelerate corrosion of copper and steel in AC pipes and outdoor units. Systems here run year-round under severe pressure from heat and high humidity, raising leak risk. Before any charging, the system must be leak-free, or the refrigerant will escape again quickly.
Al Thaghr sits in south Jeddah near the coast, a seaside district of villas, apartment blocks and tourist facilities exposed to salt and humidity.
Most tourist facilities and villas use multi-unit splits or central systems, and outdoor units here corrode rapidly from the effects of moist coastal air.
The AC setup in Al Thaghr
- 1
Multi-unit splits in villas and facilities
Villas and tourist facilities in Al Thaghr use multi-splits, with outdoor units directly exposed to humidity and salt.
- 2
Central system in large hotels
Large hotels and resorts use complex central systems, with exposed pipes rapidly corroded by the coastal environment.
- 3
Outdoor units exposed to salt and humidity
Outdoor units here need regular checks and may require protective coating or replacement of corroded parts due to rapid deterioration.
Before the visit
Before our visit in Al Thaghr
- 1
Ensure safe access to the outdoor unit
Units on balconies or roofs may be in risky spots, ensure the team can access them safely without slipping or falling.
- 2
Have salt spray or equivalent available for inspection
We may need to carefully inspect the area around the outdoor unit to check for hidden corrosion or leaks, and clean water helps with cleaning.

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.
Does coastal humidity speed up corrosion of copper pipes?
Yes, the salt and high humidity in Al Thaghr greatly speed up corrosion. We inspect pipes regularly and may recommend protective coating or replacing heavily damaged sections.
My outdoor unit is on a balcony facing the sea, does that increase leaks?
Yes, direct exposure to salty humid air speeds up rust in pipes and connections. We recommend checks at least every three months.
The outdoor unit is leaking refrigerant, how do you repair it in a coastal area?
We locate the leak precisely, clean salt and moisture from the area, repair it, vacuum thoroughly, and charge the system. We may recommend protective coating after repair.
My unit loses refrigerant quickly, is it because of the coastal climate?
The leak may be due to humidity and salt, but could also be from old corrosion in the pipes. We need precise electronic detection to locate it exactly.
