Significant changes are on the way for the heating and cooling business! Cooling systems transitioning from R-410a to newer refrigerants like R-454B refrigerant and R-32 refrigerant will be implemented in 2025. These new coolants are engineered to be better for the environment and meet new regulations about global warming. But what does that mean for your current HVAC system and future services?
This transition will reduce the environmental footprint of our air conditioning systems. Beginning in 2025, new AC systems will use a a different class of refrigerants that better align with climate goals. If you're considering getting an AC replacement soon, this is the ideal time to investigate how these updates can affect your home's comfort.
Why Is R-410a Refrigerant Being Phased Out by New Regulations?
For years, R-410a was the standard refrigerant for residential air conditioners because it worked so well. But research revealed that R-410a still contributes to global warming. In response, the Environmental Protection Agency (EPA) implemented a strategy back in 2021. The industry will progressively phase out R-410a to make room for refrigerants that are more eco-friendly.
The HVAC industry has undergone transitions like this before. When the industry moved away from using R-22 (commonly called Freon) to R-410a, residents like you had to adjust. And in the same way, this change will impact how systems are constructed as well as the recommended procedures for HVAC maintenance. Both property owners and HVAC technicians need to plan for these new refrigerants if they wish to continue enjoying the most reliable, most energy-efficient cooling possible.
Which New Refrigerant Is Replacing R-410a?
The new batch of refrigerants are categorized under the new "A2L" classification and encompass the newest R-454B refrigerant and R-32 refrigerant coolants. They're engineered to provide the same powerful cooling while significantly reducing their global warming potential (GWP) compared to R-410a.
R-454B refrigerant is anticipated to be especially useful due to its GWP being around 78% lower than R-410a. While R-454B refrigerant is technically more flammable than R-410a, updates to system configurations and maintenance practices will ensure servicing is just as safe to perform. Additionally, contemporary cooling systems using R-454B refrigerant are considerably more energy efficient, contributing to substantial savings on energy bills over time, especially if you keep up with routine HVAC maintenance.
This change isn't just about substituting the refrigerant—it impacts the whole HVAC system because the characteristics of R-454B refrigerant make it incompatible with older systems. Ultimately, every residence and business using R-410a will have to upgrade to one of the new systems.
R-410a Replacement: How Can I Prepare to Make the Shift to New HVAC Refrigerants?
Switching to the new refrigerants will not be as straightforward as replacing what's used in your home's HVAC system. That's because the distinct properties of R-454B refrigerant and R-32 refrigerant mean you can't use them in a system that uses R-410a. But rest assured—you can continue to use your current R-410a system for now. Just keep in mind that as time goes on, the price of repairs and tune-ups will go up as R-410a becomes less available.
Anticipating the changes is the optimal way to stay on top of things. If your AC system is already getting old, this is the perfect time to consider upgrading to a newer model that uses the new R-454B refrigerant. Plus, the HVAC specialists here at Kirkfield Heating & Air Conditioning can support you with switching with flexible options for HVAC replacement financing.
Which Refrigerant Is in My AC System?
Unsure which refrigerant your AC system employs? In general, you can easily locate this information by inspecting the label on your outdoor unit. This label shows the type of refrigerant, the model number and many other particulars about your cooling system.
But if you have difficulty reading the label or can't find your user manual, don't worry! You can always call one of the expert technicians at Kirkfield Heating & Air Conditioning to assist you in determining this information. Get all the info you need by reaching out at 204-272-8128.
