Low-GWP Refrigerants: What Contractors Should Know

Are you ready for the refrigerant revolution? With increasing environmental concerns and stringent regulations, the HVAC industry is shifting towards low-GWP (Global Warming Potential) refrigerants. As a contractor, staying informed about these changes is crucial. In this post, we’ll explore the landscape of low-GWP refrigerants, highlighting key trends, benefits, and what you need to know to stay ahead.

Understanding the Market and Regulations

The market for low-GWP refrigerants is booming. By 2025, it is expected to reach 204.71 kilotons, growing at a 7.85% CAGR to hit 298.70 kilotons by 2030. This growth is fueled by regulatory changes and the demand for eco-friendly HVAC refrigerants. The EPA now mandates refrigerants with a GWP of 700 or less for new equipment, with a ban on R-410A systems starting January 1, 2026. Are you prepared for these changes?

Key Players and Refrigerant Options

In June 2025, R-32 and R-454B dominated the market, accounting for 76% of ducted unitary equipment sales. These A2L refrigerants are favored for their lower GWP and energy efficiency. Fluorocarbons and HFOs also hold a significant share due to their compatibility and OEM endorsements. Meanwhile, hydrocarbons, ammonia, and CO₂ are gaining traction in specific sectors like food and beverage, making up 37% of the market share.

R32 and R454B: The Future of HVAC

Daikin’s R-32 systems, available through Mar-Hy Distributors, are increasingly popular for their compliance with EPA rules and energy efficiency. Contractors appreciate the training provided for safe handling of these mildly flammable A2L refrigerants. As a contractor, understanding the benefits and safety protocols of R32 and R454B refrigerants will give you a competitive edge.

Preparing for the Transition

  • Ensure all new installations comply with GWP limits before January 2026.
  • Invest in A2L-compatible tools and PPE certified for R-32 and R-454B refrigerants.
  • Stay updated with manufacturer training sessions for safe refrigerant handling.

Conclusion

The transition to low-GWP refrigerants is not just a trend—it’s the future of HVAC. By understanding the market dynamics and preparing for regulatory changes, you can position yourself as a leader in sustainable refrigerant solutions. Start by exploring the benefits of R32 and R454B refrigerants and ensure your team is trained and equipped for the future.
