Australia’s refrigeration and air conditioning industry is undergoing one of its most significant transitions in decades. The HFC phase-down program in Australia is progressively reducing the supply of high Global Warming Potential (GWP) refrigerants, directly impacting building owners, facilities managers, strata managers and asset managers responsible for HVAC infrastructure.
If your building relies on systems using R410A, R404A, R407C or other high-GWP gases, you are already feeling the effects — rising refrigerant costs, supply constraints, and increased pressure to modernise ageing equipment.
In this guide, we explain:
What the HFC phase-down means for commercial properties
Which refrigerants are affected
What will replace HFC refrigerants
How this impacts commercial AC maintenance and servicing
Why forward planning protects your operating budget
Whether you oversee a single commercial building or a multi-site portfolio, understanding this transition is critical for long-term cost control and compliance.

1. What Is the HFC Phase-Down in Australia?
The Australian Government is progressively reducing the import quota of Hydrofluorocarbon (HFC) refrigerants under its commitment to reduce greenhouse gas emissions.
From 1 January 2026, the national HFC import quota has been reduced by a further 19%, bringing total allowable imports to 4.25 million tonnes CO₂-equivalent — nearly 50% below the original baseline. The program will continue to step down until an 85% reduction is achieved by 2036.
This staged reduction means:
Less high-GWP refrigerant is available in the market
Increased pricing pressure
Greater demand for alternative solutions
Accelerated transition to lower-GWP technologies
For businesses relying on commercial air conditioning installation and servicing, this is not a future issue — it is happening now.

2. Why Are HFC Refrigerants Being Phased Out?
HFC refrigerants were originally introduced to replace ozone-depleting substances. However, while they do not damage the ozone layer, many HFCs have extremely high global warming potential.
For example:
R404A: GWP ~3,922
R410A: GWP ~2,088
R407C: GWP ~1,774
These values mean that if released into the atmosphere, these gases trap thousands of times more heat than carbon dioxide.
The HFC refrigerant being phased out is part of Australia’s commitment to international climate agreements. The goal is to reduce environmental impact while encouraging adoption of safer, more sustainable alternatives.
3. Which Refrigerants Are Affected?
Many common commercial systems currently use refrigerants that are facing supply pressure or phase-out:
Phased Out or Near End-of-Life:
R507
R407F
R438A
R422D
Constrained Supply / Price Volatility:
R404A
R410A
R407C
For facilities managers responsible for budgeting commercial AC service contracts, these supply constraints directly influence repair costs and long-term asset strategy.
4. How the Phase-Down Impacts Commercial AC Maintenance
The HFC phase-down Australia program affects daily operations more than many realise.
1. Increased Commercial AC Maintenance Costs
When the refrigerant supply tightens:
Leak repairs become more expensive
Recharge costs increase
Stock availability delays repairs
Routine commercial AC maintenance now requires closer monitoring of refrigerant charge levels to minimise losses.
2. Greater Emphasis on Preventative Maintenance
A proactive commercial HVAC maintenance service becomes essential. Leak detection, pressure checks and performance testing help prevent costly refrigerant losses.
3. Risk to Ageing Equipment
Systems over 10–15 years old are particularly vulnerable. If a major leak occurs in an older system using high-GWP refrigerant, repair may no longer be economically viable.
This is why HVAC repair and maintenance service strategies must now include refrigerant risk assessment.
5. Rising Costs & Supply Volatility Explained
Reduced national import quotas create a classic supply-demand imbalance.
As high-GWP refrigerants become scarcer:
Wholesale pricing fluctuates
Quotation validity periods shorten
Emergency repair costs rise
Budget forecasting becomes more complex
Facilities managers relying solely on reactive HVAC system service and maintenance are likely to face unpredictable financial exposure.
The solution? Strategic planning rather than emergency response.
6. What Will Replace HFC Refrigerants?
One of the most common questions we receive is: what will replace HFC refrigerants?
The answer depends on system type and application.
Many new-generation refrigerants offer significantly lower GWP while maintaining performance efficiency. Examples include R32 and newer blended alternatives.
Benefits:
Lower environmental impact
Improved energy efficiency in many applications
Compliance with future regulations
Natural refrigerants are increasingly popular in commercial applications.
These include:
CO₂ (R744)
Ammonia (R717)
Hydrocarbons (R290, R600a)
CO₂ systems in particular are gaining traction in commercial refrigeration and some HVAC applications due to ultra-low GWP (GWP of 1).
When evaluating commercial air conditioning installation and servicing options, selecting the lowest practical GWP refrigerant is now a key design consideration.

7. Retrofit vs Replacement: What Are Your Options?
When facing refrigerant constraints, property owners generally have two pathways:
Option 1: Retrofit
A retrofit modifies an existing system to operate with a lower-GWP refrigerant.
Advantages:
Lower capital cost than full replacement
Reduced downtime
Extends useful life of equipment
Limitations:
Not always technically viable
May involve performance trade-offs
Retrofits can be an effective cost-control strategy within a structured commercial HVAC maintenance service program.
Option 2: Full Replacement
Replacing ageing systems with new equipment designed for low-GWP refrigerants offers:
Higher energy efficiency (improved COP)
Lower lifecycle cost
Long-term refrigerant security
Improved reliability
For systems already approaching end-of-life, proactive replacement avoids reactive emergency capital expenditure.
8. The Role of Commercial HVAC Maintenance Service in Asset Protection
In a phase-down environment, preventative maintenance becomes even more critical.
A comprehensive commercial HVAC maintenance service should include:
Refrigerant leak inspections
Performance benchmarking
Coil cleaning and airflow optimisation
Compressor condition monitoring
Asset lifecycle tracking
Professional commercial AC service ensures systems operate efficiently, reducing energy consumption and limiting refrigerant loss.
The most cost-effective strategy is combining HVAC repair and maintenance service with long-term capital planning.
9. Planning Commercial Air Conditioning Installation and Servicing in 2026 and Beyond
Forward-thinking building owners are now integrating refrigerant risk into capital works planning.
Key considerations include:
1. Asset Age Review
Identify systems over 10–15 years old.
2. Refrigerant Type Audit
Document which refrigerants are currently in use across your portfolio.
3. Energy Efficiency Assessment
New systems using lower-GWP refrigerants often deliver improved performance and lower power consumption.
4. Staged Upgrade Planning
Avoid replacing multiple systems simultaneously under emergency conditions.
Strategic commercial air conditioning installation and servicing ensures smoother budgeting and improved asset resilience.
10. Practical Steps for Facilities & Building Managers
To manage the HFC phase-down Australia transition effectively:
Conduct a refrigerant audit across all assets.
Review your commercial AC maintenance contract to ensure leak detection is prioritised.
Plan retrofit feasibility assessments.
Allocate future CAPEX for low-GWP upgrades.
Engage a trusted provider for ongoing HVAC system service and maintenance.
Buildings that act early will experience fewer financial shocks than those forced into reactive upgrades.
Proactive commercial AC maintenance combined with staged replacement planning:
Reduces long-term operating costs
Improves energy efficiency
Protects asset value
Enhances sustainability credentials
The transition away from high-GWP refrigerants is inevitable. The only variable is whether you manage it strategically or reactively.
Plan Early, Protect Your Budget
The HFC refrigerant being phased out is not just an environmental policy — it is a direct operational and financial consideration for every commercial building owner in Australia.
The HFC phase-down Australia program will continue tightening supply through to 2036. High-GWP refrigerants will become more expensive and less accessible. Ageing systems relying on these gases will carry increasing financial risk.
The good news? There are clear pathways forward.
Through structured commercial HVAC maintenance service programs, retrofit assessments, and planned commercial air conditioning installation and servicing upgrades, you can:
Maintain operational continuity
Reduce environmental impact
Improve energy efficiency
Stabilise long-term costs
