This rule primarily targets refrigerants with a high global warming potential, and it's stirring up a mix of emotions for both HVAC professionals and homeowners.
Owner of The Original Kingwood Air Conditioning and Heating Stephanie Marquard explained that the EPA's goal of this rule is to protect the environment and public health by phasing out refrigerants that contribute to climate change.
Switch to new refrigerants
One of the most widely used refrigerants in homes is R-410A. Due to its high GWP, it is now being phased out.
Instead, manufacturers will transition to using refrigerants in the A2L classification, specifically R-32 and R-454B, which have a lower GWP, making them a more environmentally friendly choice.
“R-32 is a pure refrigerant, meaning it’s a single-component substance, while R-454B is a blend that includes R-32 as one of its components," Marquard said. "Both refrigerants are more environmentally friendly than R-410A due to their significantly lower GWP, but they also come with their own set of challenges.”
Cons of the new refrigerants
As the HVAC industry transitions to new refrigerants like R-32 and R-454B, there are clear advantages, but also a few challenges for homeowners to consider.
One of the biggest concerns for homeowners is the increased cost associated with the new refrigerants. Systems that use R-32 and R-454B typically cost between 20% to 30% more than traditional systems using R-410A.
“R-32 and R-454B are also mildly flammable, which means they require additional safety measures, such as sensors to detect leaks. These precautions add another layer of complexity and cost to the installation process,” Marquard said. “Homeowners should be prepared for a larger upfront investment, but it's important to keep in mind that R-32 and R-454B are more efficient, which can lower electrical costs.”
Pros of the new refrigerants
One benefit of R-32 and R-454B refrigerants is that they are more energy efficient than R-410A.
R-32 requires 20% less refrigerant to achieve the same cooling performance because it is more efficient at transferring heat, allowing for the same cooling output with less refrigerant.
R-454B also offers energy savings, providing about 5% better efficiency compared to R-410A. Its composition allows it to operate more efficiently, meaning it can absorb and release heat more effectively, using less energy to achieve the same cooling performance.
What this means for homeowners
For homeowners, the immediate concern is cost and the need for equipment upgrades. The new refrigerants come with higher production costs, which will be passed on to the consumer.
Despite these added expenses, Marquard stressed that homeowners don't need to rush into switching their equipment if their current system is functioning well.
"You can still purchase R-410A systems until 2026, and existing units will continue to be serviced for many years," Marquard said. "Though manufacturers will stop producing new R-410A systems, homeowners with existing units will still have access to replacement parts and refrigerant for maintenance. So, while the industry shifts to newer refrigerants, there’s no need to worry about your current system—it will be supported for years to come."
However, homeowners who are concerned about the future scarcity and cost of R-410A equipment may want to start considering a switch sooner rather than later. The phase out of R-410A will also lead to an increase in prices as manufacturers reduce production to comply with the new regulations.
