TLDR

• ASHRAE and UNEP renewed their partnership with a two-year plan to guide safer, low-global warming refrigerants and improve HVAC system rules worldwide.
• The plan focuses on managing refrigerants throughout their lifecycle, including production, use, leak prevention, and disposal, with new safety training and AI tools for technicians.
• Contractors, property managers, and homeowners will need to adapt to new refrigerants like mildly flammable A2L types, updated service procedures, and compliance requirements.

On September 10, 2026, ASHRAE and the United Nations Environment Programme renewed their global partnership to guide the future of refrigerants and HVAC systems. This two-year plan focuses on managing refrigerants throughout their entire lifecycle — from production and import to service and safe disposal. The update affects contractors, property managers, and homeowners alike, as it sets new expectations for handling low-global warming potential (low-GWP) refrigerants, including mildly flammable types. Safety, training, and compliance will all play a bigger role in how HVAC equipment is specified, installed, and maintained moving forward.

Policy signals: handling, training, and disposal

The renewed ASHRAE and UNEP partnership offers guidance—not new laws—but this advice shapes codes and National Ozone Units worldwide. The focus is on low-GWP refrigerants, which have a lower global warming potential. This means we will see more use of A2L refrigerants, like R-32 and R-454B. A2L refrigerants are mildly flammable, so handling them safely is key. Expect tighter rules on keeping leak logs, using certified recovery equipment, and documenting proper disposal at the end of a system’s life. These steps help prevent leaks and protect the environment while ensuring compliance with evolving standards.

Bids, budgets, and replacement planning

Contractors should factor in extra time for A2L safety training and include tools rated for A2L refrigerants in their quotes. This means using detectors and recovery gear designed for mildly flammable refrigerants like R-32 and R-454B. Property managers need to update capital plans to cover possible ventilation improvements and new standard operating procedures for servicing these systems. Some buildings may require adjustments to meet safety codes. Homeowners should know that newer HVAC systems often use R-32 or R-454B refrigerants to comply with future regulations and improve efficiency. Planning replacements with sizing tools and checking local rebates can help make these upgrades smoother and more affordable. This approach ensures everyone stays compliant and ready for the changing refrigerant landscape.

AI field tools and A2L‑ready gear

AI-enabled checklists help technicians follow exact steps when charging refrigerants, testing for leaks, and recovering gases. This reduces mistakes and improves safety on the job. Because low-GWP refrigerants like A2L types are mildly flammable, technicians need tools designed for safety. Use A2L-compatible gauges, recovery machines, and leak detectors. Spark-free tools are preferred in areas where flammable refrigerants are present to prevent ignition. To support safe handling, new fact sheets explain best practices for working with these flammable refrigerants. These materials also connect ASHRAE chapters directly with National Ozone Units, helping ensure consistent training and compliance worldwide. Together, these AI tools, safety gear, and updated resources make handling next-generation refrigerants safer and easier for contractors, property managers, and homeowners alike.

Action plan for each segment

Contractors should enroll their teams in A2L safety training to handle mildly flammable refrigerants properly. They need to audit their tools and vans to ensure all equipment is A2L-compatible. Locking standard operating procedures for leak logs and refrigerant recovery helps maintain compliance and safety. Property managers should map refrigerants used at each site to keep track of compliance and risks. Adding leak monitoring and end-of-life refrigerant recovery to service contracts will improve lifecycle management and reduce environmental impact. Homeowners should use sizing tools to find the right system for their home. They should ask which refrigerant is used in their quotes to understand future compliance and safety. Planning installation windows carefully ensures safe handling of new refrigerants. Each group has clear steps to prepare for the low-GWP refrigerant transition and stay ahead of evolving HVAC rules and best practices.

Key Takeaways

• ASHRAE and UNEP renewed their partnership for 2026–2027 to guide safer, low-GWP refrigerant use across the HVAC industry, focusing on managing refrigerants throughout their full lifecycle from production to disposal.
• The renewed pact addresses the growing use of mildly flammable A2L refrigerants like R-32 and R-454B, emphasizing new safety training, certified recovery, and stricter leak monitoring requirements for contractors and technicians.
• Property managers must update service plans to include refrigerant leak monitoring and end-of-life recovery procedures to ensure compliance with evolving guidelines and maintain building safety.
• AI-powered technician tools and updated safety fact sheets will help standardize HVAC service steps, reduce errors, and support the transition to low-GWP refrigerants with proper handling and equipment.

Frequently Asked Questions

What is the ASHRAE and UNEP partnership renewal about?

ASHRAE and UNEP renewed their partnership with a new two-year work plan for 2026–2027. The agreement focuses on managing refrigerants throughout their lifecycle, from production to disposal, and promotes safer, more environmentally friendly HVAC practices.

How will this partnership affect contractors and their work?

Contractors will need to update their training to handle new low-GWP refrigerants, especially mildly flammable A2L types. They’ll also use specialized tools and follow stricter safety and leak management procedures to meet evolving guidelines.

What should property managers know about these changes?

Property managers should plan for compliance by mapping refrigerant types at their sites, updating service contracts to include leak monitoring, and preparing for possible ventilation or equipment upgrades. This helps avoid costly surprises and ensures safer, greener buildings.

Why are low-GWP refrigerants important for homeowners?

Low-GWP refrigerants have a lower global warming impact, making new HVAC systems more eco-friendly. Homeowners should expect future replacements to use these refrigerants, which may require different equipment and safety considerations.
