The Changing Landscape of Refrigerants: What Homeowners Need to Know

If you own an HVAC system, you've probably heard about refrigerants—the substances that help cool your home. But what you may not know is that major changes are happening in the HVAC industry regarding which refrigerants can be used. These changes are driven by environmental concerns and government regulations, and they could impact your home's cooling system. Here’s what you need to know.

Why Are Refrigerants Changing?

For decades, refrigerants have played a crucial role in air conditioning and refrigeration, but some of the older ones have been found to contribute to ozone depletion and global warming. In response, governments worldwide have introduced regulations to phase out harmful refrigerants and replace them with more environmentally friendly alternatives.

What’s Being Phased Out?

• R-22 (Freon): This refrigerant was widely used in HVAC systems for many years but was officially phased out in the U.S. as of January 1, 2020. If your system still uses R-22, refilling it has become expensive since production has stopped, and only reclaimed or recycled R-22 is available.

• R-410A (Puron): While R-410A was introduced as a more environmentally friendly alternative to R-22, it still has a high global warming potential (GWP). As a result, it is also being phased down, with restrictions starting in 2025.

What’s Replacing Them?

The HVAC industry is transitioning to new refrigerants with lower environmental impact, including:

• R-32: Already used in some residential systems, R-32 has a significantly lower GWP than R-410A and is more energy efficient.

• R-454B (Puron Advance): This is another emerging replacement for R-410A, offering similar performance with a much lower environmental footprint.

What Does This Mean for Homeowners?

1. If You Have an Older System Using R-22

   • Repairs requiring refrigerant refills will become increasingly costly.

   • It may be more cost-effective to replace your system rather than continue maintaining it.

2. If Your System Uses R-410A

   • Your system is still supported, but the industry is moving toward newer refrigerants.

   • Future replacement systems will likely use R-32 or R-454B.

   • If you're planning to upgrade your HVAC system in the next few years, ask your contractor about the refrigerants available.

3. New Systems Will Be More Efficient

   • The next generation of refrigerants is designed to be more environmentally friendly and energy-efficient.

   • Investing in a new system could lower energy bills and reduce your carbon footprint.

Final Thoughts

The transition to new refrigerants is a necessary step for environmental sustainability. While these changes may seem overwhelming, they present an opportunity to upgrade to more efficient systems that will save money in the long run.
