What is R32 refrigerant?

R32 is a hydrofluorocarbon (HFC) refrigerant that has become the default choice in modern split air conditioning systems across Perth and Australia. It replaced the older R410A refrigerant in most new equipment from major manufacturers over the past five years.

The key difference between R32 and R410A is global warming potential (GWP). R32 has a GWP of 675 compared to R410A's GWP of 2088, meaning it contributes roughly one-third as much to atmospheric warming if released. This lower environmental impact drove the shift as Australian refrigerant regulations tightened.

Technicians working with R32 systems in Perth will notice faster heat transfer and better cooling efficiency compared to older refrigerants. The lower charge volume required in R32 systems (typically 30% less refrigerant by weight) also reduces leak risks and makes servicing more cost-effective. Most air conditioning contractors now stock R32 as standard and have certification to handle it.

R32 does have one drawback: it is mildly flammable, which means installation and servicing require strict safety protocols. Licensed technicians follow specific procedures to prevent leaks and ensure safe handling. If you are installing or upgrading a split system in Perth, most new units will use R32, making it the practical standard for energy-efficient air conditioning today.
