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.

What the work covers
- Pressure check and leak location
- Leak repair before charging
- 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 Naeem is a relatively modern district mixing detached villas and residential towers with moderate spacing between homes and green areas providing shade, yet high heat and sometimes high humidity put persistent stress on cooling systems. The copper tubing in this residential mix suffers leaks from repeated thermal expansion and high circuit pressure. Careful inspection and repair of any leak before charging is essential protection against refrigerant waste and to maintain the required cooling capacity.
Al Naeem in north Jeddah is a modern district mixing villas and residential towers, exposed to variable heat and humidity.
The residential mix here includes separate split units in villas and central systems in some towers, all needing close leak inspection.
The AC setup in Al Naeem
- 1
Separate split units in villas
Villas in Al Naeem have separate split units with reasonable distances between indoor and outdoor sections.
- 2
Central systems in some towers
Some residential towers have central cooling with long runs, requiring careful inspection of every circuit section.
- 3
Outdoor units on roofs and balconies
Outdoor units are mounted on villa roofs or tower balconies, exposed to continuous heat and pressure.
Before the visit
Before our visit in Al Naeem
- 1
Confirm your system type
Tell us if you have a villa with separate split or a tower with central system so we bring the right equipment.
- 2
Provide the outdoor nameplate photo
A clear photo of the outdoor unit's nameplate tells us the refrigerant type and correct charge before we arrive.
- 3
Ensure access and measurement capability
Let us know if the outdoor unit is on a roof or balcony, and confirm the team can reach and measure safely.

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.
What is the difference in checking refrigerant in a villa versus an apartment tower?
Villas have separate split units, while towers may have central systems with longer runs. Both need careful inspection, but longer runs in central systems raise leak probability.
Does variable heat and humidity affect charge stability?
Yes, fluctuation between heat and humidity causes repeated metal and joint expansion and contraction, raising microscopic leak risk.
How often should I check the refrigerant in Al Naeem?
We recommend inspection every six to nine months due to variable heat and humidity, and any drop indicates a leak needing repair.
How do you ensure the charge is correct for the unit's specification?
We obtain the unit's nameplate with the refrigerant type and amount, use precise equipment to measure pressure and weight, then charge exactly to those specifications.
