Starting in 2025, Canada and the US will change regulations regarding the types of refrigerants allowed to be used for cooling systems. This will affect both Air Conditioning and some Heat Pump systems. Refrigerant is the fluid that runs through your HVAC system to cool warm air. The refrigerant changes from liquid to gas during this process. The refrigerant gas is then condensed to a liquid to start the cycle again.
What are the Changes to the Refrigerant Regulations?
The goal of the new regulations is to phase out the use of refrigerants containing hydrofluorocarbons (HFCs), commonly used in older cooling systems. By lowering the global warming potential (GWP) of refrigerants used in these systems in Canada, we can help to reduce the associated impacts on climate change from unavoidable equipment leaks.
Older HVAC systems commonly use R-410A refrigerant, which, while effective in cooling, has a high GWP. Beginning in January 2025, the new refrigerant regulations will require the use of newer refrigerants, such as R-32 and R-454B.
Do I need to replace my current system?
If you have an HVAC system that currently uses one of the refrigerants being phased out, the current regulations do not require you to replace it. Manufacturers will continue to support older systems with parts, and the refrigerants will still be available. There will likely be little impact on costs initially, but as newer products are implemented, an increase in costs for older refrigerants is likely.
It’s important to keep your cooling system well-maintained. However, when it comes time to replace your current system or if you are looking for a more climate-friendly one, the good news is that there are several benefits to the new types of refrigeration. These new systems are more energy efficient, reducing greenhouse gas (GHG) emissions from electricity use, and the refrigerant has lower GWP. For example, R-454B has no ozone depletion potential (ODP) and low toxicity.
Lancaster’s Commitment to Our Customers
The low GWP alternatives the industry is shifting toward are classified as mildly flammable compared to traditional HFCs. All Lancaster HVAC technicians have undertaken specialized training to handle these new refrigerants safely. Our sales team can also guide you through the newest options available for your next AC or Heat Pump unit, ensuring your new equipment will comply with the new and any expected changes to regulations.
