Major 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 coming in 2025. These new coolants are engineered to be better for the environment and comply with updated regulations about global warming. But what does that mean for your present HVAC system and any new services?
This shift will reduce the environmental impact of our air conditioning systems. Starting with 2025, new AC systems will employ an alternative class of refrigerants that are more compatible with climate goals. If you're thinking about getting an AC replacement soon, this is the perfect time to explore how these changes can impact your home's comfort.
Why Are They Phasing Out R-410a for New HVAC Refrigerant?
For a long time, R-410a was the go-to refrigerant for residential air conditioners because of its effectiveness. But research uncovered that R-410a still affects global warming. As a result, the Environmental Protection Agency (EPA) implemented a plan back in 2021. The industry will progressively phase out R-410a to introduce refrigerants that are more environmentally friendly.
The HVAC industry has made changes like this before. When the industry switched from using R-22 (commonly called Freon) to R-410a, residents like you had to adjust. And in the same way, this shift will affect how systems are constructed as well as the recommended procedures for HVAC maintenance. Both property owners and HVAC technicians should plan for these new refrigerants if they wish to continue enjoying the most secure, most energy-efficient cooling possible.
What Refrigerant Is Replacing R-410a?
The coming refrigerants fall under the new "A2L" classification and encompass the newest R-454B refrigerant and R-32 refrigerant coolants. They're engineered to offer the same efficient cooling while greatly lowering their global warming potential (GWP) compared to R-410a.
R-454B refrigerant is expected to be especially efficient due to its GWP being around 78% less 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. In addition, contemporary cooling systems using R-454B refrigerant are much more energy efficient, contributing to considerable savings on energy bills over time, especially if you stay on top of routine HVAC maintenance.
This switch isn't only about changing the refrigerant—it affects the whole HVAC system because the characteristics of R-454B refrigerant make it incompatible with older systems. Ultimately, every home and business using R-410a will be required to switch to one of the new systems.
R-410a Replacement: What Do I Need to Do to Change to New HVAC Refrigerants?
Changing to the new refrigerants won't be as simple as substituting 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 the new refrigerants in a system designed to use R-410a. But don't be concerned—you can continue to use your current R-410a system for now. Just know that as time passes, the price of repairs and tune-ups will rise as R-410a becomes less available.
Planning ahead is the most effective way to manage things. If your AC system is already nearing the end of its lifespan, this is the ideal time to think about investing in a newer model that uses the new R-454B refrigerant. Plus, the staff here at Select Comfort Systems can help you in switching with flexible options for HVAC replacement financing.
Which HVAC Refrigerant Is in My Air Conditioner?
Unsure which refrigerant your AC system utilizes? In general, you can easily learn this information by examining the label on your outdoor unit. This label indicates the type of refrigerant, the model number and various other specifications about your cooling system.
But if you have difficulty reading the label or can't find your user manual, don't stress! You can always connect with one of the expert technicians at Select Comfort Systems to assist you in identifying the refrigerant. Get all the info you need by reaching out at 801-305-4777.
