Significant changes are on the horizon 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 designed to be better for the environment and satisfy updated regulations about global warming. But what does that mean for your present HVAC system and any new services?
This transition will decrease the environmental effect of our air conditioning systems. Beginning in 2025, new AC systems will use a a different 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 new refrigerants can impact your home's comfort.
Why Exactly Is R-410a Being Phased Out?
For a long time, R-410a was the preferred refrigerant for residential air conditioners because of its effectiveness. But studies showed that R-410a still negatively impacts global warming. In response, the Environmental Protection Agency (EPA) enacted a strategy back in 2021. The industry will progressively phase out R-410a to introduce refrigerants that are better for the environment.
The HVAC industry has implemented changes like this before. When the industry phased out R-22 (commonly called Freon) to R-410a, property owners like you had to adapt. And similarly, this transition will impact how systems are designed as well as the recommended procedures for HVAC maintenance. Both property owners and HVAC technicians need to plan for these new refrigerants if they want to continue enjoying the most reliable, most economical cooling possible.
New HVAC Refrigerants Replacing R-410a?
The coming refrigerants belong to the new "A2L" classification and include the newest R-454B refrigerant and R-32 refrigerant coolants. They're engineered to provide the same effective cooling while substantially decreasing 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% less than R-410a. Although R-454B refrigerant is actually more flammable than R-410a, updates to system configurations and maintenance practices will ensure servicing is just as safe to perform. In addition, today's cooling systems using R-454B refrigerant are much more energy efficient, contributing to substantial savings on energy bills over time, especially if you stay on top of routine HVAC maintenance.
This switch isn't simply about replacing the refrigerant—it impacts the whole HVAC system because the characteristics of R-454B refrigerant make it not suitable for use in older systems. Ultimately, every household 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 Make the Shift to New HVAC Refrigerants?
Transitioning to the new refrigerants isn't as straightforward as replacing what's used in your home's HVAC system. That's because the unique 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 worry—you can still use your current R-410a system for now. Just remember that as time progresses, the price of repairs and tune-ups will go up as R-410a becomes harder to find.
Anticipating the changes is the most effective way to stay on top of things. If your AC system is already getting old, this is the best time to consider switching to a newer model that uses the new R-454B refrigerant. Plus, the HVAC specialists here at Dearing's Service & Solutions can support you with making the transition with flexible options for HVAC replacement financing.
Which Refrigerant Is in My AC System?
Uncertain which refrigerant your AC system employs? In general, you can easily find this information by checking the label on your outdoor unit. This label indicates the type of refrigerant, the model number and many 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 professional technicians at Dearing's Service & Solutions to assist you in determining this information. Get all the details you need by reaching out at 812-200-5844.
