22LB R454B R-454B Refrigerant Gas
R-454B is a next-generation refrigerant designed to replace R-410A in new HVAC systems. Offering similar performance with significantly lower environmental impact, it is the preferred low-GWP solution for air conditioning and heat pump manufacturers worldwide. As global regulations tighten, R-454B provides a reliable and future-compliant alternative for high-efficiency systems.
Key Features and Benefits
✅ Ultra-Low GWP Solution
With a Global Warming Potential (GWP) of just 466, R-454B reduces climate impact by nearly 80% compared to R-410A (GWP ~2,088), helping meet international environmental standards.
✅ Excellent System Performance
Delivers comparable capacity and energy efficiency to R-410A while enabling reduced charge sizes and better environmental credentials.
✅ Mild Flammability (A2L)
Classified as A2L – non-toxic and mildly flammable – suitable for use in new system designs built to handle low-GWP refrigerants safely.
✅ HVAC Industry Ready
Widely adopted by major manufacturers for new air conditioning, rooftop units, VRF systems, and heat pumps. Not for retrofit use.

Frequently Asked Questions
-
No. You do not need to upload a certificate to place an order. However, by purchasing refrigerant from RefrigSupply.us, you are legally certifying that you are either EPA-certified OR that the product is being purchased for resale to a certified technician. We rely on our customers to follow all applicable federal and local regulations.
-
Absolutely. We only stock virgin, factory-sealed refrigerants that meet or exceed AHRI-700 purity standards. We do not sell reclaimed or mixed gases. Every cylinder is guaranteed to perform to manufacturer specifications, ensuring the safety and efficiency of your systems.
-
We offer nationwide shipping across the contiguous United States via Hazmat-approved carriers. Orders placed before 2:00 PM EST are typically processed and dispatched the same day. Because compressed gas is classified as Hazardous Material, we cannot ship via air; all orders move via expedited ground freight.
-
Yes. We are built to support contractors and supply houses. If you need to order in pallet quantities (40+ cylinders), please contact our wholesale team directly for tiered volume pricing and dedicated freight quotes.
