This next-generation refrigerant is the industry’s solution for lowering Global Warming Potential (GWP) as the HVAC sector transitions away from R-410A. It is classified as an A2L "mildly flammable" refrigerant, which requires specific safety sensors and handling procedures during installation. At South Mini Splits, we are leading the charge by offering a dedicated category for R454B products to ensure our customers are future-proofed. Most of these new systems are compatible with high-efficiency wall mount units that utilize the latest inverter technology. Choosing a system with this refrigerant ensures your home meets the newest environmental regulations while maintaining peak cooling performance.
