Short answer
New central AC systems are moving from R-410A to lower global-warming refrigerants such as R-454B and R-32 under federal rules. Existing R-410A systems can still be repaired, and R-410A remains available for service, but prices may rise over time. If your system is old and leaking, it may be worth comparing repair against replacement.
What is changing
Federal rules phase down high-impact refrigerants in new equipment, starting with systems made from 2025.
Your existing system
R-410A systems can be serviced. You do not need to replace a working system.
