Major HVAC Refrigerant Changes Are Coming – Are You Ready?
The HVAC industry is undergoing a major transition that could impact your property operations, equipment planning, and technician training. Starting in 2025, the EPA is requiring a phase-out of traditional HFC refrigerants like R-410A in favor of new, more environmentally friendly alternatives called A2L refrigerants.
What’s Changing and Why It Matters
The new A2L refrigerants (such as R-32 and R-454B) are classified as “slightly flammable” but have much lower Global Warming Potential (GWP), aligning with federal goals under the American Innovation and Manufacturing (AIM) Act.
This shift means:
- New HFC systems must be installed by December 31, 2025, if components were manufactured before January 1, 2025.
- A2L systems will be the new standard – and they require updated safety protocols, compatible tools, and trained technicians.
- Existing systems using R-410A can still be serviced, but retrofitting them with A2L refrigerants is not allowed.
Important Deadlines
- Jan 1, 2025: No installation of 410A components manufactured/imported after this date.
- Jan 1, 2026: All new systems must be A2L-compatible.
- July 1, 2026: Leak detection & repair rules kick in for systems using 15+ lbs of HFC refrigerant.
- Jan 1, 2028: No more sales of factory-completed HFC systems.
Action Items for Our Industry
✔️ Schedule technician training on A2L refrigerants
✔️ Ensure tools and leak detectors are A2L-compatible
✔️ Review HVAC equipment inventory and plan for phase-outs
✔️ Check storage ventilation and labeling for new safety standards
Why Training Matters Now
Technicians must understand how to safely store, handle, and install A2L refrigerants. EPA Section 608 certification updates and manufacturer-specific training are strongly recommended.
⚠️ Don't get caught off guard—2026 will be here before you know it!
