R32 Compatibility Guide: What You Need to Know Before Buying Tools

If you're working in the HVAC field in Australia—whether as a licensed tradie, facility manager, or hands-on DIYer—there's one refrigerant you're seeing more and more of: R32. And that’s no coincidence.

R32 is the new standard in many split systems due to its lower environmental impact, better efficiency, and growing government mandates. But here’s the catch: not every HVAC tool is safe or suitable for R32.

This guide walks you through what R32 refrigerant is, why compatibility matters, and which R32 HVAC tools in Australia you can trust.

What Is R32 Refrigerant and Why It Matters

R32 (difluoromethane) is a low-GWP (global warming potential) refrigerant that’s become the go-to gas for many residential and commercial air conditioning systems in Australia.

Key R32 Features:

• GWP of 675 (compared to 2088 for R410A)
  
  
• Higher efficiency = lower power bills
  
  
• Mildly flammable (classified A2L)

Because it’s a flammable refrigerant, using R32 requires care—not just in how you handle it, but also in the tools you use.

Which Tools MUST Be R32-Compatible?

There’s no getting around it. Certain HVAC tools must be R32-compatible for safety and compliance. Here’s the must-have gear you should double-check:

✅ Manifold Gauge Sets

If you're charging or recovering R32 systems, your manifold must be pressure-rated and leak-resistant. Many older gauge sets aren’t certified for A2L refrigerants.

✅ Recovery Machines

This is critical. Non-R32-rated recovery units can spark, overheat, or fail entirely when used with flammable refrigerants.

✅ Hoses

Vacuum and charging hoses need R32-rated seals and pressure ratings. Using generic hoses may result in small leaks—especially under pressure.

✅ Vacuum Pumps

While many standard vacuum pumps can evacuate R32 systems, the oil used must be fresh and clean—and the pump should ideally be spark-proof.

✅ Leak Detectors

Your detector must specifically include A2L refrigerants like R32. Not all universal models do.
