As of January 2026, the industry has fully transitioned to low-GWP refrigerants like R-454B and R-32. While new systems using these refrigerants cost 10–15% more than older R-410A models, many Miami contractors are offering clearance discounts of 20–30% on remaining R-410A stock, which remains legal to service for its 15+ year lifespan.
