Find the leak first
Refrigerant charging in Al Hindawiyah
In Al Hindawiyah, old downtown Jeddah, shops and flats in closely built blocks need periodic refrigerant checks because leaks may be slow and unnoticed for weeks. Alrabih's team detects even tiny leaks with specialist tools, repairs them, then charges the circuit with the correct refrigerant.

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 Hindawiyah's buildings are older, mixing ground-floor shops with residential flats, and most units are older splits mounted on narrow facades or tiny balconies. High coastal humidity, continuous heat and the tight building pack mean constant pressure on copper lines and joints, and leaks here may show as quiet performance drop rather than loud hissing. Regular checks and swift repair are essential to avoid costly compressor fixes later.
Al Hindawiyah sits in historic downtown Jeddah, an older closely built district around the popular markets.
Most AC units here are relatively older splits per shop or flat, with outdoor units mounted on narrow facades due to lack of spacious outdoor areas.
The AC setup in Al Hindawiyah
- 1
Older split per shop and flat
Most shops and flats in Al Hindawiyah have one relatively older split, with the outdoor unit on a narrow facade or small balcony.
- 2
Window units in some very old units
A few very old flats still use window units, which need extra care when checking for leaks due to their easily damaged seals.
- 3
Outdoor units on narrow facades or tiny balconies
All outdoor units here are mounted in very tight spaces due to architectural constraints, requiring skill and experience working in tight areas.
Before the visit
Before our visit in Al Hindawiyah
- 1
Tell us the outdoor unit location and the facade
Be clear about which facade and floor the outdoor unit is on, and ensure safe access from the street or balcony is possible.
- 2
Coordinate with the shop or flat owner in advance
Tell the shop owner or flat owner about the visit time and expected duration, especially if the shop is open during business hours.
- 3
Confirm the facade and fixings are safe
Check the outdoor unit is safely fixed and the brackets are sound, and tell us if you see serious rust marks or cracks.

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.
An old shop with an older split unit, how do you check for leaks?
We use a very sensitive electronic leak detector to check every joint and pipe, especially older ones weakened by rust and corrosion.
Streets are narrow and facades close together, can you safely work on outdoor units?
Yes, our team is used to working in tight spaces and sensitive facades. We coordinate with the shop or flat owner to find the safest time and method.
Do sea humidity and strong heat in Al Hindawiyah speed up leaks in older joints?
Yes, strongly. Coastal humidity and sustained heat speed up copper joint corrosion, especially in older units. Six-monthly checks beat annual ones in these cases.
Old building wiring is weak, does that strain the compressor after charging?
Weak wiring can strain the compressor over time. We check connection quality before charging and advise you to have an electrician inspect the wiring if we spot issues.
