Significant changes are on the horizon for the heating and cooling industry! Cooling systems moving 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 friendlier to the environment and satisfy revised regulations about global warming. But what does that mean for your existing HVAC system and future services?
This change will decrease the environmental effect of our air conditioning systems. Starting with 2025, new AC systems will use new class of refrigerants that more closely match with climate goals. If you're contemplating getting an AC replacement soon, this is the opportune time to explore how these new refrigerants can affect your home's comfort.
Why Exactly Is R-410a Being Phased Out?
For years, R-410a was the go-to refrigerant for residential air conditioners because of its efficiency. But analysis revealed that R-410a still contributes to global warming. In response, the Environmental Protection Agency (EPA) established a strategy back in 2021. The industry will gradually eliminate R-410a to make room for refrigerants that are more eco-friendly.
The HVAC industry has implemented shifts like this before. When the industry switched from using R-22 (commonly called Freon) to R-410a, homeowners like you had to adapt. And in the same way, this change will influence how systems are designed as well as the optimal methods for HVAC maintenance. Both residents and HVAC technicians should get ready for these new refrigerants if they wish to keep experiencing the most reliable, most cost-effective cooling possible.
What Refrigerant Is Replacing R-410a?
The coming refrigerants belong to the new "A2L" classification and contain the newest R-454B refrigerant and R-32 refrigerant coolants. They're designed to provide the same efficient cooling while substantially decreasing their global warming potential (GWP) compared to R-410a.
R-454B refrigerant is anticipated to be particularly effective due to its GWP being around 78% less than R-410a. While R-454B refrigerant is actually more flammable than R-410a, enhancements to system designs and maintenance practices will ensure servicing is just as safe to perform. In addition, modern cooling systems using R-454B refrigerant are much more energy efficient, leading to substantial savings on energy bills over time, especially if you stay on top of routine HVAC maintenance.
This change isn't just about substituting the refrigerant—it impacts the whole HVAC system because the components of R-454B refrigerant make it not suitable for use in older systems. In time, every household and business using R-410a will need to upgrade to one of the new systems.
R-410a Replacement: What Should I Consider in Order to Transition to New HVAC Refrigerants?
Changing to the new refrigerants isn't as easy as substituting what's used in your current HVAC system. That's because the different properties of R-454B refrigerant and R-32 refrigerant make existing R-410a systems incompatible. But rest assured—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 increase as R-410a becomes harder to find.
Preparing in advance is the optimal way to stay on top of things. If your AC system is currently nearing the end of its lifespan, this is the perfect time to consider switching to a newer model that uses the new R-454B refrigerant. Plus, the staff here at Olde Towne Heating & Air can support you with upgrading with flexible options for HVAC replacement financing.
What HVAC Refrigerant Does My Air Conditioner Use?
Not sure which refrigerant your AC system uses? In general, you can easily find this information by checking the label on your outdoor unit. This label shows the type of refrigerant, the model number and various other details about your cooling system.
But if you are unable to decipher the label or are missing your user manual, remain calm! You can always connect with one of the skilled technicians at Olde Towne Heating & Air to help you in determining this information. Get all the information you need by giving us a call at 843-485-0967.
