It’s a blend of R-32 (68.9%) and R-1234yf (31.1%) that delivers cooling performance comparable to R-410A while dramatically lowering its climate impact (GWP ≈ 466 vs. ~2,088 for R-410A). With zero ozone depletion potential (ODP = 0) and strong energy efficiency, R-454B is quickly becoming the standard choice for residential and light-commercial HVAC, including split systems, rooftops, VRF, packaged units, heat pumps, and new low-GWP chillers.\u003c\/p\u003e\n\u003cp\u003eClassified by ASHRAE as A2L (low toxicity, mildly flammable), R-454B is engineered for safe use in properly designed equipment that meets today’s codes. OEMs pair it with modern safety features such as leak detection and rapid air-dilution designs, and it aligns with current U.S. regulations (EPA AIM Act) and global F-Gas rules that restrict high-GWP refrigerants. Note: R-454B is intended for \u003cem\u003enew\u003c\/em\u003e systems and is not a drop-in retrofit for R-410A equipment. When you want future-ready comfort with a smaller environmental footprint, R-454B is the smart, regulation-compliant upgrade path\u003c\/p\u003e","brand":"Wiesecs","offers":[{"title":"20.9lb","offer_id":58204058747267,"sku":null,"price":356.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1001\/1603\/8019\/files\/22LbR454BRefrigerant_2.jpg?v=1780930122","url":"https:\/\/wiesecs.com\/products\/limited-stock-100-new-factory-sealed-r454b-refrigerant-20-9lb","provider":"Wiesecs","version":"1.0","type":"link"}
