For a long time, R-22 was the primary refrigerant used in air conditioning or heat pump technology. In fact, the name “Freon” was so widely used that it was almost universally known more than the technical name, R-22. But eventually, due to scientific studies that measured its global warming potential, it was phased out with R-410A.
Now, we’re seeing that even R-410A has serious global warming potential when compared to some newer, more efficient refrigerants that are being developed today. If you’re the owner of an air conditioning system, or you’ll be purchasing an heat pump installation in Vero Beach, then you’ll want to know exactly what kinds of refrigerants are phasing out and which ones are all the rage. That’s what we’ll discuss with you today.

Phasing Out Means New Products Are Coming In
The phase-out of R-410A and R-22 marks a significant shift in the HVAC industry as it aligns with global efforts to reduce greenhouse gas emissions and mitigate climate change. Both R-410A and R-22 have been widely used in residential and commercial HVAC systems, but their high Global Warming Potential (GWP) and environmental impact have led to their planned replacement by newer, more sustainable refrigerants.
Phase-Out of R-22
R-22, commonly known as Freon, was widely used in air conditioning and refrigeration systems for decades. However, it is an ozone-depleting substance with a high GWP, making it a target for phase-out under the Montreal Protocol. Production and import of R-22 have been banned in many countries since 2020, leaving recycled and reclaimed supplies as the only options for servicing existing systems. This has driven up costs and encouraged property owners to replace aging systems with those using environmentally friendly refrigerants.
Phase-Out of R-410A
R-410A, introduced as a replacement for R-22, gained popularity due to its non-ozone-depleting properties and higher energy efficiency. However, with a GWP of 2,088, R-410A contributes significantly to global warming. Under the Kigali Amendment to the Montreal Protocol and various regional regulations, the production and use of high-GWP refrigerants like R-410A are being reduced, with complete phase-outs expected in the coming years. Manufacturers are now transitioning to low-GWP alternatives, including A2L refrigerants.
Rise of A2L Refrigerants
A2L refrigerants, characterized by low flammability and lower GWP, are emerging as the primary replacements for R-22 and R-410A. Examples include R-32, R-454B, and R-1234yf. These refrigerants offer significant environmental benefits, with GWPs reduced by up to 80% compared to R-410A. Additionally, their thermodynamic properties allow for improved system efficiency, resulting in lower energy consumption and operating costs.
The adoption of A2L refrigerants requires updates to safety standards and installation practices due to their mild flammability. Technicians must be trained to handle these refrigerants safely, and system designs must incorporate features like leak detection and ventilation. Despite these challenges, the benefits of A2L refrigerants, including their reduced environmental impact and alignment with global sustainability goals, make them the logical next step for the HVAC industry.
The shift from R-22 and R-410A to A2L refrigerants reflects the industry’s commitment to environmental responsibility, ensuring compliance with international regulations while delivering safe and efficient cooling solutions.
