Rockwall Low-GWP A2L Refrigerant Transition & 2026 HVAC Compliance
Under the EPA's AIM Act regulations, the HVAC industry is transitioning from R-410A to next-generation mildly flammable (A2L) low-global-warming-potential (GWP) refrigerants, primarily R-454B and R-32. Our technicians are factory-trained in A2L handling, safety leak detection sensors, and spark-proof evacuation equipment, ensuring Rockwall homeowners receive compliant, future-proof installations.
What the EPA Low-GWP Transition Means for Rockwall Homeowners
Existing R-410A systems remain completely legal to operate and service, and replacement parts will continue to be manufactured for years. However, new systems installed starting in 2025 and 2026 feature next-generation refrigerants paired with factory integrated refrigerant leak detection sensors.
