Why R410A Is Getting Harder to Source
The AIM Act Is Phasing Down R410A on a Fixed Schedule
The EPA’s AIM Act cut HFC production to 90% of the 2022 baseline back in 2022 and 2023, and we’re now in the steeper stretch: 2024 through 2028 caps production at 60% of that baseline, a 40% reduction that only gets tighter in 2029, 2034, and 2036. R410A is one of the refrigerants losing allowance every step of the way, so supply gets harder to find and prices trend upward regardless of who you buy from. Read the full breakdown in the EPA’s AIM Act phasedown schedule.
New Equipment Manufacturers Have Already Moved On
Most OEMs building new residential and light commercial AC systems have already switched their production lines to A2L refrigerants, and R454B is the one showing up most often. If you’re quoting new installs, the refrigerant question isn’t really about R410A anymore. It’s about having a supplier who already stocks what the new equipment actually needs, and can tell you honestly whether that’s still R410A or something newer.
What This Means When You're Bidding a Job
If you’re bidding new-construction or major replacement work, the refrigerant line item on your quote should already reflect where supply is headed, not just where it’s been. Locking in a supplier who stocks R454B alongside R410A means you’re not caught flat-footed mid-project if R410A pricing or availability shifts before the job wraps.
R454B: The New-Equipment Standard Replacing R410A
Built by Chemours as Opteon XL41
R454B is the HFO blend Chemours markets as Opteon XL41 (see Chemours’ official Opteon XL41 specifications), engineered specifically for new-generation AC systems rather than as a retrofit charge for older R410A units. It runs 78% lower GWP than R410A (467 vs. roughly 2,088), which is the main reason equipment manufacturers designed around it once the AIM Act made the phasedown schedule official.
What A2L Actually Means for Your Crew
A2L means lower toxicity and mildly flammable, a step up from the fully nonflammable A1 class R410A carries, but nowhere near the higher-flammability A3 blends some cheaper alternatives use. It burns slowly and only under specific conditions, so equipment built for it uses A2L-rated components and leak detection per UL 60335-2-40. That’s a real handling difference, not just a line on the SDS, and it’s worth knowing before your crew touches a cylinder for the first time.
Performance You Won't Have to Explain to a Customer
R454B delivers similar cooling capacity to R410A with better energy efficiency, and compressor discharge temperatures land close enough to R410A that most new equipment platforms don’t need a redesigned compressor to run it. That’s part of why the transition has been smoother for OEMs than earlier refrigerant swaps, and it’s one less thing you have to explain when a customer asks why their new system runs on a different refrigerant than the one they had before.
R454B Refrigerant Specifications
Global Warming Potential (GWP)
R454B carries a GWP of 467, compared to roughly 2,088 for R410A, about a 78% reduction. That’s the number driving the whole industry shift, since AIM Act allowances are allocated by GWP-weighted volume, not just pounds produced.
ASHRAE Safety Classification
R454B is classified A2L: Class A for lower toxicity, Class 2L for lower flammability. Every cylinder we ship reflects that classification accurately on its documentation, no shortcuts, and no relabeling to make paperwork easier down the line.
Cylinder Sizes We Stock
We keep R454B in stock from 20 lb cylinders up through 750 lb, so whether you need one cylinder for a single install or a pallet for a fleet of new-construction jobs, you’re not waiting on a special order. Local Bradenton and Sarasota County customers can typically pick up the same day, and national orders ship out through our regular delivery routes.
Where R454B Gets Used
New Residential and Light Commercial AC Systems
This is the primary use case: new-build and new-install AC systems designed from the factory to run R454B, not older R410A equipment being converted.
OEM Equipment Lines Already Shipping A2L-Ready
Most major HVAC manufacturers have already transitioned new equipment lines to A2L refrigerants, so contractors installing new systems are increasingly working with R454B by default, not by special request.
Contractors Standardizing New-Install Inventory
Contractors who install new systems regularly are consolidating around R454B now instead of stocking two refrigerants and guessing which job needs which one.
Not Just Split Systems, Heat Pumps and Chillers Too
R454B isn’t limited to standard split AC units. It’s approved for positive displacement and direct expansion systems, heat pumps, and chillers across residential, light commercial, and commercial equipment, so if you’re quoting anything beyond a basic split system, there’s a good chance R454B is already the spec.
R454B vs R410A: What's Actually Different
Here’s the side-by-side so you’re quoting the right refrigerant for the right job.
| Specification | R410A | R454B |
|---|---|---|
| GWP | ~2,088 | 467 |
| ASHRAE Safety Class | A1 (nonflammable) | A2L (mildly flammable) |
| AIM Act Phasedown Status | Allowance shrinking through 2028 and beyond | Not tied to the same declining allowance schedule |
| Typical Use | Existing/legacy AC systems | New equipment designed for A2L refrigerants |
| Equipment Requirements | Standard components | A2L-rated components and leak detection |
R454B isn’t a drop-in charge for an existing R410A system. It’s built for new equipment from day one, which is exactly why OEMs are shipping it that way, and why your quote for a new install should already default to R454B unless the customer has a specific reason to ask for something else.

Why We Don't Post R454B Pricing Online
Refrigerant pricing depends on volume, cylinder size, distance, and whether you’re a one-time buyer or a standing account, so a number on a webpage would either be wrong for your order or wrong for the next contractor who reads it. We’d rather quote your actual job than publish a figure that doesn’t apply to you. That’s the same reason we compete well against corporate procurement departments: they’re built for volume contracts, we’re built to pick up the phone and get you a real number the same day you ask. Call (941) 371-0300 or request a quote online, and you’ll talk to someone who actually handles refrigerant, not a call center reading from a script.
R454B Refrigerant FAQ
Is R454B the same as R32?
No. R454B is a blend of R-32 and R-1234yf (68.9% and 31.1% by weight), not pure R32. The blend is what gets the GWP down to 467 while keeping performance close to R410A.
Can I still buy R410A from American Refrigerants?
Yes, we stock R410A for existing systems and service work while supply allows. If you’re specifying new equipment, though, R454B is worth checking first since that’s what most new installs are already built for.
Does R454B require different tools or gauges?
Yes, technicians need A2L-rated manifold gauges, recovery equipment, and leak detectors since standard R410A tools aren’t rated for the classification. If your crew hasn’t made that switch yet, that’s worth budgeting for alongside your first R454B order.
What is R454B refrigerant used for?
R454B is used in new residential and light commercial AC systems built to run A2L refrigerants, replacing R410A as the standard charge for new equipment coming off the line today.
Is R454B a drop-in replacement for R410A?
No. R454B is designed for new equipment, not as a retrofit charge for an existing R410A system. The components and safety design aren’t interchangeable between the two.
What is the GWP of R454B refrigerant?
R454B carries a GWP of 467, compared to roughly 2,088 for R410A, a reduction of about 78%, confirmed by Chemours’ own published specifications for the refrigerant.
Is R454B refrigerant flammable?
R454B is ASHRAE-classified A2L, which means mildly flammable under specific conditions, not the higher-flammability A3 classification some other low-GWP blends carry.
What cylinder sizes does American Refrigerants stock for R454B?
We stock R454B from 20 lb cylinders up to 750 lb, covering everything from a single new install to a full pallet order.
Does American Refrigerants ship R454B nationwide?
Yes. We ship R454B nationwide in addition to serving our local Bradenton and Sarasota County customers directly.
