Why Are R404A Prices Rising in Australia?

✅ Why Are R404A Prices Rising in Australia?

Australia’s HFC phase-down under the Kigali Amendment is the main driver. R404A, with its high global warming potential (GWP ~3,922), is being phased out under strict refrigerant bans and regulations:

Planned milestones

  • July 2027: Service ban on virgin R404A.
  • July 2029: Service ban extended to recycled R404A.

These HFC quota reductions mean less supply and higher costs for businesses still using R404A.

🚨 Refrigerant Supply Shortage and Price Surge

  • Import quotas are shrinking year-on-year, creating a refrigerant supply shortage.
  • Distributors have announced price increases, with R404A among the hardest hit.
  • Industry experts predict further hikes as refrigerant price forecasts for Australia in 2026 show continued upward pressure.

🔍 Why R404A Is Still in Demand

Despite rising costs, many supermarkets, cold storage facilities, and transport refrigeration systems still rely on R404A.

Retrofitting or replacing these systems is expensive, and low-GWP refrigerants often require equipment modifications.

🌱 Best Alternatives to R404A for Australian Businesses

If you’re wondering how to replace R404A in refrigeration systems, here are some of the top options:

  • R448A vs R404A: Lower GWP (~1,300), suitable for retrofits – but real world feedback is that this refrigerant is not ideal for retrofit to low temperature systems without careful consideration, due to higher compressor discharge temperatures.
  • R452A vs R404A: Matches R404A in cooling capacity, discharge temp, and energy efficiency. Higher GWP than newer blends: Though lower than R404A.
  • CO₂ refrigeration systems (R744): Ideal for new installations, energy-efficient, and future-proof.
  • R290 (Propane): Natural refrigerant gaining traction in commercial refrigeration, works beautifully and super energy efficient – however charge quantity limits apply due to the perceived danger of flammability.

Choosing between R404A, R448A, R449A, R452A, or even natural refrigerants like CO₂ and R290 isn’t a simple decision. Each pathway has pros and cons depending on:

  • System age and design (retrofit vs new install)
  • Budget constraints (short-term vs long-term cost)
  • Regulatory compliance timelines (phase-down deadlines)
  • Energy efficiency goals
  • Service availability and technician expertise

For Example:

  • R452A is retrofit-friendly and reduces GWP by ~45% compared to R404A, but it’s still a mid-term solution with a relatively high GWP, subject to price rises and availability.
  • R448A/R449A offer lower GWP (~1,300) and good efficiency, but may require more system adjustments and application limitations.
  • CO₂ systems are future-proof and sustainable, but involve higher upfront costs and specialized installation.
