R32 is now the standard refrigerant across most Aussie HVAC-R installs — but its A2L classification means your vacuum pump needs to be spark-free, not just capable. This guide covers why standard brush-motor pumps are a safety risk on R32 systems, how spark-free brushless DC technology works, and what's actually different about evacuating an R32 system versus R22

R32 vs R410A is one of the biggest refrigerant comparisons for modern air conditioning, especially as more systems shift toward lower-GWP options. This guide explains the key differences in efficiency, environmental impact, safety, and servicing, while helping readers understand why R32 is becoming the preferred choice for many newer air conditioners.
