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.

- 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
Prince Fawaz North is a medium-density residential area of modern villas and low to mid-rise apartment buildings, mostly with independent split units or shared refrigerant circuits among multiple heads. Seasonal heat and humidity subject the compressor to sustained high pressure, stressing connections and coils. Leaks here often develop gradually and show no obvious symptoms until weeks have passed.
Prince Fawaz North is in south Jeddah within a developed residential zone of villas and apartment blocks fitted with split-system air conditioning.
Most units here are split systems with relatively short copper runs, but continuous high pressure from the heat increases the risk of leakage at solder joints.
The AC setup in Prince Fawaz North
- 1
Independent split per villa and flat
Most villas and flats in Prince Fawaz North have separate outdoor units, simplifying each circuit but multiplying the number of independent systems.
- 2
Shared split feeding multiple indoor heads
Some modern apartment buildings in the area have one outdoor unit supplying refrigerant to multiple heads across different flats.
- 3
Older window units in some established villas
Some of the older villas in Prince Fawaz North have not yet switched from window units.
Before the visit

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.
My AC seems to work, but the refrigerant keeps dropping, is there definitely a leak?
Dropping refrigerant with normal operation is a clear sign of a leak, not normal consumption. We inspect the circuit with an electronic detector and pinpoint the leak.
The heat here is intense, does that speed up leaks?
Yes, the high pressure from intense heat accelerates refrigerant loss through existing leaks. That's why we check for leaks early before obvious performance drops.
Does fixing a leak mean complex repairs, can it be done quickly?
It depends on where the leak is. If it's at a simple solder joint, we might fix it in an hour. If it's in a coil or the outdoor unit, we may need to replace that part.
After the new charge, how soon can I tell the leak is really fixed?
We monitor the pressure for at least an hour after charging. If it stays stable, the repair is good. If pressure drops again, there's another leak we missed.
