For over 20 years, R410A has been the standard refrigerant in residential HVAC systems across Canada. It replaced R22 (also known as Freon) due to R22’s ozone-depleting effects.
Since January 1st, 2025, the HVAC industry has been in a new direction. Now, new air conditioners and heat pumps imported into Canada will use low-impact refrigerants like R32 or R-454B instead of R410A. This transition supports a global effort to reduce hydrofluorocarbon (HFC) emissions by 85 percent by the year 2036.
Why This Change Is Happening
Although R410A does not damage the ozone layer, it has a high Global Warming Potential (GWP) of 2,088. GWP is a measure of how much heat a greenhouse gas traps in the atmosphere. In comparison, newer refrigerants like R32 (GWP of 675) and R-454B (GWP of 466) have significantly lower GWPs and are considered more environmentally responsible.
Since most HVAC systems sold in Canada are manufactured elsewhere, these global changes will also be seen in Canada.
What Homeowners Should Expect
No Immediate Replacement Needed
If your current HVAC system uses R410A and is working properly, there is no need to replace it. These changes only apply to the production of new systems, not existing ones.
R410A Will Still Be Available
Even though new systems will no longer be built with R410A, the refrigerant itself will remain available for servicing and repairs well into the future.
New Units Will Use Different Refrigerants
When the time comes to replace your system, expect your new air conditioner or heat pump to run on R32 or R-454B. These refrigerants are being widely adopted across North America because of their performance and environmental advantages.
Start Planning if Your System Is Aging
If your HVAC unit is over 15 years old, now is a good time to start planning for a replacement. Newer systems are more efficient, use environmentally responsible refrigerants, and can help you avoid unexpected breakdowns or emergency costs.
Benefits of Upgrading to R32 or R-454B
When it’s time to replace your HVAC system, upgrading to a model that uses R32 or R-454B can offer several long-term benefits:
- Reduced environmental impact
- Improved energy efficiency and performance
- Lower energy bills and maintenance costs
- Easier access to refrigerants and replacement parts
- Eligibility for potential government rebates and energy-saving incentives
Final Thoughts
This refrigerant transition is part of a larger push toward environmental responsibility in the HVAC industry. It is not a ban on R410A, and it does not mean your current system is outdated or in need of immediate replacement. R410A will remain available for service for many years to come.
For homeowners, the most important thing is to stay informed. When you eventually replace your air conditioner or heat pump, your new system will likely use R32 or R-454B. These next-generation refrigerants are designed to meet today’s efficiency standards while reducing environmental impact.
