Ducted and central recharge
AC refrigerant charging in Abhur Al Janoubiyah
In Abhur Al Janoubiyah, north Jeddah, villas and apartment blocks often complain of uneven cooling across zones, though the cause may not be refrigerant loss. Alrabih's team reads the pressure and temperature first, identifies any leak, then vacuums and charges the unit to the refrigerant type listed on its nameplate.

When your system needs a refrigerant charge
- 1
Uneven cooling across zones
One office or floor feels hot while the rest of the building is cool. Before adding any refrigerant, the technician reads pressures and temperatures at several points to confirm that a low charge is actually the cause.
- 2
After a repair or component swap
Replacing a compressor, a valve or any part that opens the circuit means the old charge escapes. It must be recovered with a dedicated machine, then the line is vacuumed and recharged after the repair is done.
- 3
A system restarted after long shutdown
A central or rooftop unit shut down for a full season in Jeddah's salty coastal air may have lost part of its charge. We verify with pressure readings before adding anything, and look for a leak if the readings point to one.
Who it's for
Your villa's ducted system has lost its cooling
We read system pressures and line temperatures, find any leak in the long pipe runs, then vacuum and charge to the refrigerant type on the unit nameplate.
Ask on WhatsAppYour building's rooftop unit cools unevenly across floors
We inspect the system and its drawings, measure pressures and temperatures at multiple points to find the cause, then recover the old charge if a repair is needed and recharge to the nameplate type only.

- Old refrigerant charge recovery
- Line vacuum before recharging
- Charge to nameplate refrigerant type
How we work
How we work
- 1
System check and readings
The technician checks the unit nameplate and system drawings, then reads suction and discharge pressures and line temperatures to judge the actual charge condition.
- 2
Find and fix the leak
If readings show a low charge, the technician finds the leak in the long line set, joints or components, and repairs it before any refrigerant is added.
- 3
Recovery and vacuum
The remaining old charge is recovered with a dedicated recovery machine, then a vacuum pump removes all air and moisture from the line before the new charge goes in.
- 4
Charge and verify
The system is charged with the refrigerant type on the nameplate only, never mixed with another type, then pressures are read again and cooling is checked across all zones.
Careful charge or a random top-up?
| Alrabih | The usual way | |
|---|---|---|
| Diagnosing the cause | Pressures and temperatures first | Add refrigerant straight away |
| The leak | Found and fixed before charging | Left to repeat the problem |
| Old charge | Recovered by machine | Vented to atmosphere |
| Refrigerant type | Nameplate type, no mixing | Whatever is to hand |
| Long line sets | Joints checked along the full run | Checked at the unit only |

What sets this district apart
Abhur Al Janoubiyah is home to relatively modern villas and apartment blocks with central AC systems distributed across several rooms and suites, and in the hot, humid summer, cooling gaps between rooms often appear. This may signal a slow refrigerant leak or pressure and balance faults, but random charging can damage the system instead of fixing it. Precise pressure and temperature readings before any charge are essential to diagnose the real problem and confirm the refrigerant matches the unit's original specification.
Abhur Al Janoubiyah lies in north Jeddah, a modern residential area with spacious villas and multi-storey apartment blocks.
Most units here are central AC systems distributed across multiple zones, each requiring separate pressure and temperature readings to pinpoint any leak.
The AC setup in Abhur Al Janoubiyah
- 1
Multi-zone central AC system
Central units in villas and blocks here distribute air across multiple rooms and wings, and each zone may need separate pressure and temperature readings.
- 2
High-load outdoor units in summer
Summer humidity and high heat raise the outdoor unit's load, raising pressure and reducing charge efficiency if it is not correctly set.
- 3
Long distribution pipes through the villa
Long pipes running through villa rooms and wings may develop slow leaks due to high pressure and heat.

Tell us which zones cool and which do not
Before we visit, identify which rooms or wings cool well and which are warm or cool poorly.
- 2
Ensure the outdoor unit is accessible
The outdoor unit may sit on the roof or in the villa garden, so ensure the team can reach it safely and easily.
- 3
Have the unit's original nameplate ready
The unit's nameplate shows the original refrigerant type and specs, letting us charge correctly without error.

FAQ
Questions about AC refrigerant charging
Why can't a second refrigerant type be mixed into a ducted system?
Every refrigerant type is matched to a specific compressor, lubricating oil and operating pressures. Mixing two types shifts the pressures and contaminates the oil, straining the compressor and ruining cooling performance. We read the nameplate type and use only that.
Can a rooftop unit be recharged without shutting the whole building down?
In most cases one rooftop unit can be worked on while the others keep running, but this depends on how the system is designed and how many units it has. The technician reviews the system drawings at the survey and decides the approach that causes least disruption.
What do pressure and temperature readings tell you about a central AC system?
Suction pressure and gas line temperature show how well the evaporator coil is absorbing heat, while discharge pressure and liquid line temperature reveal condenser performance. Comparing both sets against the manufacturer's values shows whether the charge is low, high or whether another component is the real problem.
Why is the old charge recovered rather than just released?
Releasing refrigerant to the air damages the ozone layer and is prohibited. Recovery keeps the gas for proper recycling or disposal. In large systems the charge is substantial, so recovery both protects the environment and avoids losing a costly material before the repair is complete.
How does charging a ducted system differ from charging a standard split unit?
A ducted system has much longer refrigerant line sets and a larger charge, so a shortage takes longer to appear and leak-finding covers a much greater length of pipe and joints. Pressure readings must also be compared against the manufacturer's values for the whole system, not just a single indoor unit.
One room cools and another stays warm, is the refrigerant low?
It may not be low refrigerant; it could be a slow leak or a pressure balance fault between zones. We measure pressure and temperature in each zone first before any charge.
Does high summer humidity affect the refrigerant?
Humidity does not affect the refrigerant itself, but it increases system load and can make cooling gaps more apparent. Careful diagnosis determines whether there is a leak or a pressure problem.
My villa is large with AC across several wings, how do you locate the leak?
We read pressure and temperature separately in each wing, identify which loses pressure faster, then trace the leak point with specialist detection equipment.
Does my old refrigerant type differ from modern types?
Yes, refrigerant types have changed over the years for environmental reasons, so we read the unit's nameplate and charge with the same type listed, never a different modern one.
