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
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.
Can you work after trading hours?
Yes. Retail, restaurant and office work is routinely scheduled at night or early morning under a permit-to-work so trading is not interrupted.
How fast can you get to me?
Emergency callouts are dispatched to the next available technician, with the arrival window confirmed by SMS when the vehicle leaves.
Do you top up gas without finding the leak?
No. A weighed charge into a leaking system is money out the window, so the leak is found and repaired first, then the system is evacuated and charged to the plated weight.
