| 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.
Is a compressor replacement guaranteed?
Yes. Replacements are done with a system flush and new drier, and both part and workmanship are warranted, provided the original cause of failure is corrected.
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.
