Major 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 designed to be friendlier to the environment and meet updated regulations about global warming. But what does that mean for your current HVAC system and upcoming services?

This transition will minimize the environmental impact of our air conditioning systems. In 2025, new AC systems will utilize new class of refrigerants that better align with climate goals. If you're thinking about getting an AC replacement soon, this is the perfect time to explore how these updates can affect 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 efficiency. But studies revealed that R-410a still negatively impacts global warming. Because of this, the Environmental Protection Agency (EPA) established a plan back in 2021. The industry will steadily discontinue R-410a to replace it with refrigerants that are more eco-friendly.

The HVAC industry has made shifts like this before. When the industry switched from using R-22 (commonly called Freon) to R-410a, property owners like you had to follow suit. And just like then, this change will affect how systems are constructed as well as the best practices for HVAC maintenance. Both property owners and HVAC technicians must get ready for these new refrigerants if they wish to continue enjoying the most reliable, most energy-efficient cooling possible.

New HVAC Refrigerants 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 created to provide the same efficient cooling while greatly lowering their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is expected to be particularly effective due to its GWP being about 78% less than R-410a. While R-454B refrigerant is actually more flammable than R-410a, improvements to system designs and maintenance practices will ensure servicing is just as safe to perform. In addition, today's cooling systems using R-454B refrigerant are significantly more energy efficient, resulting in big 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 incompatible with older systems. Ultimately, every residence and business using R-410a will need to upgrade to one of the new systems.

R-410a Replacement: How Can I Prepare to Change to New HVAC Refrigerants?

Switching to the new refrigerants will not be as simple as swapping out the new coolants with 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 don't be concerned—you can continue to use your current R-410a system for now. Just be aware that as time progresses, the cost of repairs and tune-ups will go up as R-410a becomes scarcer.

Planning ahead is the most effective way to manage things. If your AC system is currently getting old, this is the best time to consider investing in a newer model that uses the new R-454B refrigerant. Plus, the staff here at McFadden Heating & Cooling can support you with making the transition with flexible options for HVAC replacement financing.

Which HVAC Refrigerant Is in My Air Conditioner?

Uncertain which refrigerant your AC system uses? In general, you can easily learn this information by checking the label on your outdoor unit. This label displays the type of refrigerant, the model number and numerous other particulars about your cooling system.

But if you have difficulty reading the label or are missing your user manual, don't stress! You can always call one of the skilled technicians at McFadden Heating & Cooling to help you in figuring it out. Get all the info you need by contacting us at 519-683-2339.
