Pressure testing, leak detection, vacuum and accurate weighed re-gas of R410a, R32 and legacy R22 systems. In River Club this is sandton prime work on all split types systems, attended within about 50 minutes of dispatch.On Daikin equipment specifically — inverter splits, vrv multi-storey systems and ducted plant — the faults we see most in River Club are refrigerant loss at flare joints and outdoor pcb failure after surge events.Every visit starts with a full diagnostic and a written quote before any part is fitted.Golf-course adjacent; some properties have restricted rear access. Aircon Repairs & Servicing bookings in River Club are logged against Block 6 so we can allow for power availability on site.

Refrigerant data
| Gas | Classification | Suction pressure | Discharge pressure | Typical use |
|---|---|---|---|---|
| R410a | HFC blend (A1) | 280-320 kPa at 7 degrees C evaporating | 2 600-3 000 kPa at 45 degrees C ambient | Most inverter splits, ducted systems, VRV/VRF and heat pumps installed since 2005. |
| R32 | HFC (A2L, mildly flammable) | 300-340 kPa at 7 degrees C evaporating | 2 700-3 100 kPa at 45 degrees C ambient | Current-generation inverter splits and heat pumps. |
| R22 | HCFC (phased out) | 480-520 kPa at 7 degrees C evaporating | 1 700-2 000 kPa at 45 degrees C ambient | Legacy splits and ducted plant installed before the phase-out. |
Common questions
Why is my Daikin unit flashing its indicator light in River Club?
A flashing operation lamp means the board has logged a fault code. Pressing the cancel button on the remote and holding it cycles the code out; U0 points to a low charge, U4 to a communication fault between indoor and outdoor units, and A5 to a freeze or high pressure trip.
How often should an aircon need re-gassing?
A correctly installed system should never need gas. If it does, there is a leak, so we pressure test and repair the leak before charging rather than topping up annually.
Do you charge a callout fee?
A standard callout and diagnostic fee applies and is quoted upfront. It is credited against the repair when you accept the quote.
