When was your air conditioner installed?
This seemingly simple question could significantly impact your future AC repair bills—and potentially the fate of your entire cooling system. If the answer is “before 2010,” you’re very likely using a refrigerant that’s being phased out of the market: R-22, commonly known as “Freon.”
As a professional HVAC team with years of experience serving the Melbourne area, Aircool HVAC has been receiving increasing inquiries from homeowners with older properties: “Why are my AC repair costs getting so expensive?” “I heard Freon is being banned—can I still use my air conditioner?”
Today, we’ll thoroughly explain everything about the R-22 phase-out to help you make the smartest decision.
What is R-22? Why is the World Phasing It Out?
R-22, chemically known as chlorodifluoromethane, was once a widely used refrigerant. Since the 1950s, R-22 has been the “standard” for air conditioning and refrigeration equipment because of its excellent cooling performance, chemical stability, and low cost. For a considerable period, virtually all residential air conditioners, commercial HVAC systems, and cold storage facilities used this refrigerant.
However, scientists discovered a serious problem in the 1980s: R-22 belongs to the hydrochlorofluorocarbon (HCFC) family of substances, and when released into the atmosphere, it damages the ozone layer. The ozone layer is Earth’s “sunscreen,” filtering out most harmful ultraviolet radiation from the sun. Damage to the ozone layer means more UV rays reaching the ground, leading to increased skin cancer rates, reduced crop yields, and damage to marine ecosystems.
In 1987, the United Nations adopted the Montreal Protocol, one of the most successful international environmental agreements in human history. This protocol requires countries to gradually phase out ozone-depleting substances, and R-22 is on that list.
Australia’s Phase-Out Timeline:
Australia has been gradually reducing HCFC imports since 1996. From 2016, HCFC imports have been significantly restricted (limited to approximately 45 tonnes of R-22 annually). From 2020, R-22 can only be used for servicing existing equipment manufactured before 2020. From 2030, R-22 imports will be completely banned.
This means R-22 currently available in the market comes primarily from recycling and limited imports. As supply continues to decrease, prices naturally rise.
How to Determine if Your AC Uses R-22
Before deciding on your next steps, you first need to confirm what type of refrigerant your air conditioning system uses. Here are several simple methods:
Method 1: Check the Installation Year
The simplest criterion is the installation date. If your air conditioning system was installed before 2010, there’s a very high probability it uses R-22. After 2010, new air conditioning equipment sold in the Australian market had largely transitioned to eco-friendly refrigerants.
Method 2: Check the Equipment Nameplate
Every outdoor AC unit has a nameplate (usually on the side of the unit) that lists the equipment’s technical specifications, including refrigerant type. Look for the word “Refrigerant”—the code following it is the refrigerant model:
- R-22 / HCFC-22: This is the Freon being phased out
- R-410A: Currently the most commonly used eco-friendly refrigerant
- R-32: Next-generation low-carbon eco-friendly refrigerant
- R-407C: Another eco-friendly alternative
Method 3: Contact a Professional Technician
If the nameplate is unclear or you’re unsure how to determine the refrigerant type, the safest approach is to contact a professional HVAC technician for an on-site inspection. At Aircool HVAC, we offer free system inspections that can accurately identify your system’s refrigerant type and overall health status.
What the R-22 Phase-Out Means for You
If your air conditioner does use R-22, you must face several practical issues:
- Dramatically Rising Repair Costs
Since R-22 production and import have been heavily restricted, market inventory is decreasing. According to industry data, R-22 prices have increased significantly over the past several years. This means every repair requiring refrigerant top-up will cost considerably more than before.
- Reduced Parts and Technical Support
As R-22 systems gradually exit the market, manufacturers are reducing production of related parts. More and more older systems face the awkward situation of “having money but no parts to buy.” Additionally, younger generation HVAC technicians are primarily trained on new refrigerant systems and have relatively less experience with R-22 system repairs.
- Increasingly Prominent Efficiency Issues
Systems using R-22 typically have over 10 years of service. Even without obvious faults, their efficiency has significantly decreased. According to the Australian Energy Regulator, an air conditioner over 15 years old may consume 1.5 to 2 times the energy of a new AC with equivalent cooling capacity. In other words, a significant portion of your annual electricity bill might be “paying for” an inefficient old unit.
- Environmental Responsibility
As responsible homeowners, we should also consider environmental factors. Continuing to use R-22 systems means that with every repair and refrigerant top-up, a certain percentage will leak into the atmosphere, continuously damaging the ozone layer. Choosing to upgrade to an eco-friendly system isn’t just an economic consideration—it’s also about protecting the Earth’s environment for future generations.
Repair or Replace? A Professional Decision Guide
Facing this situation, many homeowners struggle with the question: should they continue repairing the old system or simply get a new one?
There’s no standard answer to this question—it needs to be analyzed based on your specific circumstances. Here are several key factors we recommend considering:
Factor 1: System Age
Air conditioning systems have a designed lifespan of typically 15-20 years. If your system is over 15 years old, even if it’s currently running normally, various components are approaching the end of their lifespan and could fail at any time. In this case, rather than continuously investing in repair costs, it’s better to replace the system all at once.
Factor 2: Repair Frequency and Cumulative Costs
Review your repair records from the past few years. If the system frequently has problems and cumulative repair costs are already considerable, continuing repairs makes poor economic sense. We have a simple reference standard: if a single repair cost exceeds 30% of a new system’s price, or annual repair costs exceed 15% of a new system’s price, you should seriously consider replacement.
Factor 3: Efficiency Comparison
Check your existing system’s efficiency rating and compare it to new systems on the market. New inverter split systems typically have an Energy Efficiency Ratio (EER) of 3.5 or higher, while older systems might only achieve 2.5 or lower. This means a new system producing the same cooling might only use 70% of the electricity. Based on Melbourne electricity prices, a family’s summer AC electricity cost difference could be significant annually.
Factor 4: Government Incentive Programs
The Victorian Government offers various incentives to encourage residents to use energy-efficient equipment. For example, the Victorian Energy Upgrades (VEU) program can provide substantial discounts for qualifying high-efficiency air conditioner installations. When making your decision, don’t forget to factor in these benefits—they could significantly reduce the actual cost of a new system.
Looking at the long term, replacing with a new system often has lower total costs, while providing better cooling performance and lower carbon emissions.
If You Choose to Replace, How to Select a New System?
Once you decide to replace, choosing the right new system becomes crucial. Here are some professional recommendations:
- Refrigerant Type
The mainstream eco-friendly refrigerants currently on the market are R-410A and R-32. R-32 is the newer generation refrigerant with a Global Warming Potential (GWP) only one-third that of R-410A, making it the more environmentally friendly choice. An increasing number of major brands like Daikin, Mitsubishi Electric, and Fujitsu have launched R-32 systems.
- System Type Selection
Based on your home’s structure and needs, you can choose:
- Split System: Suitable for single rooms or open-plan living areas, simple installation, lower cost
- Multi-split: One outdoor unit connected to multiple indoor units, suitable for multi-room needs
- Ducted: Delivers air through ductwork for whole-home cooling/heating, suitable for larger homes
- Energy Efficiency Rating
Australia uses a star rating label system for air conditioner efficiency. Higher stars mean better efficiency. We recommend choosing products with at least 3.5-star cooling efficiency and 4-star heating efficiency. Although higher-efficiency products cost more upfront, long-term electricity savings will make up the difference.
- Choose the Right Installation Timing
The HVAC industry has distinct peak and off-peak seasons. March-May and September-November are typically off-peak installation periods, when many companies offer discounts. If your system can last a bit longer, waiting until the off-season to replace could save you money.
- The Importance of Professional Installation
An air conditioner’s performance depends not only on the equipment itself but also largely on installation quality. Details like pipe length, number of bends, outdoor unit placement, and vacuum time all affect system efficiency and lifespan. Always choose a qualified, experienced professional team for installation.
