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
Is an LG linear compressor worth repairing in Dainfern?
On refrigerators still within their ten-year sealed system warranty, yes. Outside it, we quote the compressor and drier replacement against the value of the unit so you can decide on the numbers rather than a guess.
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.
