Refrigerant charging in Al Riyadh

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.

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.

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.

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.

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.

There is a slow leak in the sealed circuit. The unit may seem to work at first, but the ongoing leak will gradually weaken it and raise your electricity bill. We locate and fix the leak before adding new refrigerant.

Spacing in Al Riyadh is more generous than some neighbourhoods, but some villas have long pipe runs between units. We assess the site on arrival and plan the repair based on access ease.

Yes, the harsh summer heat and direct sun exposure increase pressure on the pipes and joints. An annual system inspection helps catch leaks early and avoids total refrigerant loss at peak summer.

The refrigerant type and amount are printed on the outdoor unit's nameplate. We read it on arrival and charge to the manufacturer's specification exactly. If the label is lost, we check the model number and cross-reference the records.
