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.

- 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 Bashaer is a relatively modern residential district with multi-storey apartment blocks and some villas, featuring contemporary architecture and modern designs. Most buildings have up-to-date central or split systems, with copper runs often installed inside walls or protective ducts, though leaks can occur at joints or penetration points. When refrigerant charge drops, every joint and connection must be checked before recharging, otherwise topping up alone wastes both refrigerant and energy.
Al Bashaer sits in the east, a relatively modern residential district with tall apartment blocks and contemporary architectural designs.
Most units here are central systems with smart controls, and copper runs are placed in protective ducts within or alongside walls.
The AC setup in Al Bashaer
- 1
Central system with hidden air ducts
Modern blocks here have central systems with air ducts hidden in walls and ceilings, distributing refrigerant through a single circuit.
- 2
Split units in villas with protected runs
Villas in Al Bashaer have split units with copper runs in external or internal protective ducts.
- 3
Outdoor units on roofs and rear walls
Outdoor units are mounted on secure roofs or rear walls sheltered from direct weather exposure.
Before the visit
Before our visit in Al Bashaer
- 1
Bring the original nameplate details
Finding the unit's original nameplate is essential because the new charge must match the factory-specified type and amount exactly.
- 2
Confirm outdoor unit access
Check that the outdoor unit on the roof or rear wall can be safely accessed before the visit.
- 3
Tell us if you have noticed recent cooling loss
If you have noticed weak or uneven cooling in parts of your flat or villa, tell us the location, as it may point to where the leak is.

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 building is new with central AC, are leaks rare in modern systems?
No, even modern systems can leak at joints and welds. We inspect them with precision electronic detectors before any new charge.
The copper runs are hidden in the walls, how do you detect leaks?
We use highly sensitive electronic detectors, and sometimes add a tracer dye before charging to pinpoint the leak location precisely.
Summer temperatures in Al Bashaer are high, do they affect the refrigerant circuit?
Yes, intense heat raises pressure in the circuit, potentially causing faster leaks at any weak joints.
Central AC systems are complex, is correct charging straightforward?
Correct charging relies on knowing the exact type and amount in the unit's original specifications, which is why we need the original nameplate or manual.
