The refrigerant transition is no longer coming. It's here. As of January 1, 2026, manufacturers can no longer produce or import residential and light commercial HVAC equipment using R-410A. Every new system coming off the line now runs on R-454B, an A2L refrigerant with a Global Warming Potential 75% lower than what it replaces.
For contractors, this changes a few things worth understanding.
R-454B is classified as mildly flammable. That means new handling requirements, updated safety protocols, and in most cases new or updated recovery equipment. Contractors who haven't yet gone through A2L certification training need to get it done. This isn't optional — it's a liability issue.
On pricing, expect the conversation with customers to get harder before it gets easier. New R-454B systems are running 10 to 15% more than comparable R-410A units. The right framing is simple: this is a regulatory change, not a manufacturer cash grab. Communicate it that way and most customers will accept it.
The good news on existing systems: R-410A is still available for service and repair. Homeowners with systems already in the field aren't affected by the manufacturing deadline. You can still source reclaimed and recycled R-410A for servicing existing equipment, though supply is tightening and prices are rising. A recharge that ran $150 two years ago is approaching $400 in some markets. That math is pushing more repair calls toward replacement conversations, which is not necessarily a bad thing for contractors running tight margins on service work.
The bigger picture is that this transition is creating a natural upgrade cycle. Aging R-410A systems are becoming more expensive to maintain, and customers are starting to feel it. Contractors who know the new equipment well, can explain the refrigerant story clearly, and have A2L certification in hand are positioned to win that business.
