Find the leak first
Refrigerant charging in Al Mahamid
In Al Mahamid, east Jeddah, refrigerant charging requires careful leak detection before charging, because dense, tightly spaced buildings limit outdoor unit ventilation and dust accumulates fast. We find the leak first, clean the lines, then vacuum the circuit and charge it correctly.

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 Mahamid is a relatively dense eastern residential area with closely built blocks and compact flats; the tight spacing restricts outdoor unit ventilation and makes dust accumulation faster. This strains the compressor and accelerates any refrigerant leak, especially if the unit is in a tight corner or between buildings. Our service focuses on deep cleaning before precise leak detection, and coordinating access with building management to ensure safe unit reach.
Al Mahamid is in east Jeddah, a dense residential area of closely built blocks with compact flats.
Most outdoor units in Al Mahamid are mounted in tight spaces between buildings or on small balconies, where dust accumulates quickly.
The AC setup in Al Mahamid
- 1
Split per flat with unit in cramped space
Most Al Mahamid flats have an outdoor unit in a tight corner or small balcony, with limited ventilation and quick dust buildup.
- 2
Grouped units on roofs of larger blocks
Some larger Al Mahamid blocks group multiple outdoor units on the roof, easing access but limiting ventilation between units.
- 3
Older units in confined spaces
Some older Al Mahamid units are mounted in very confined corners, where corrosion and dust significantly increase leak risk.
Before the visit

Coordinate with building management for safe access
Before the visit, tell building management so they ensure safe access to the roof or balcony where the unit is.
- 2
Confirm roof or balcony access is clear
If the unit is on a small balcony or confined roof, ensure the path is clear of obstacles and safe before the visit.

Gather distilled water and find nearby power
Evacuation needs distilled water and power nearby, so ensure both are available even if space is tight.

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 outdoor unit is wedged in a tight corner between buildings; does poor ventilation cause leaks?
Poor ventilation does not cause leaks itself, but increases dust buildup and heat around the unit, which accelerates any existing leak, so we clean and test carefully.
Al Mahamid streets are narrow; can you reach outdoor units easily?
Yes, most units are on roofs or balconies reachable from inside the building, and we coordinate with building management beforehand.
Dust accumulates fast in the tight corner; does it mask leak detection?
Yes, heavy dust masks detection, so we thoroughly clean the lines and filters before using sensitive equipment.
Small balcony with many pipes in tight space; is leak testing difficult?
Yes, tight space requires caution, but sensitive equipment detects leaks even in difficult corners, and advance coordination ensures sufficient time.
