As the HVAC industry continues phasing out high-global warming potential (GWP) refrigerants like R-410A, the adoption of low-GWP alternatives such as R-32 and R-454B is gaining momentum. These newer refrigerants offer more than just regulatory compliance,they contribute to significant environmental benefits and support global climate change mitigation strategies.
1. Dramatically Lower GWP = Reduced Climate Impact
One of the primary advantages of low-GWP refrigerants is their drastically reduced contribution to global warming.
- R-454B has a GWP of approximately 467, which is nearly 78% lower than R-410A’s GWP of 2,088.
- R-32, with a GWP of around 675, also offers a substantial reduction.
This shift translates into significantly lower greenhouse gas emissions per unit of refrigerant, making a measurable difference in the fight against climate change.
2. Higher System Efficiency = Long-Term Emissions Savings
Beyond their low GWP, both R-32 and R-454B are used in more energy-efficient HVAC systems:
- R-454B systems deliver 2–3% higher efficiency than comparable R-410A systems.
- R-32 systems can offer up to 12% energy savings over their predecessors.
Improved efficiency means less electricity is needed to cool or heat your home,reducing emissions from power generation and lowering energy bills.
3. Supports Global and National Climate Goals
Regulatory efforts such as the Kigali Amendment and the U.S. AIM Act aim to phase down the use of high-GWP refrigerants over the next 15 years. Canada’s alignment with these efforts makes switching to R-32 or R-454B not just an environmental win, but also a proactive move to comply with future refrigerant restrictions.
Making the switch now helps homeowners stay ahead of changing policies while contributing to emissions reductions on a broader scale.
4. Safety and A2L Refrigerant Training
Both R-32 and R-454B are categorized as A2L refrigerants,meaning they are mildly flammable and require proper handling and updated technician training.
To ensure safety and proper system function, it’s important that technicians are trained to work with these next-generation refrigerants.

5. A Smart Long-Term Investment
Though new systems using R-32 or R-454B may come with a slightly higher upfront cost, they offer:
- Long-term energy savings
- Lower service and replacement costs in the future
- Enhanced sustainability for your home
- Compliance with upcoming refrigerant regulations
These benefits not only lower your carbon footprint,they help protect your investment and increase your home’s environmental value.
