HVAC Refrigerants We Stock

Our HVAC refrigerant inventory covers every system type and application, including residential split systems, commercial rooftop units, mini-splits, heat pumps, cold storage, and industrial refrigeration. Below is a full breakdown of every refrigerant we carry.

R-410A Refrigerant — The Standard for Residential HVAC

R-410A remains the most widely used refrigerant in U.S. residential and light commercial HVAC systems installed between 2010 and 2025. It is a hydrofluorocarbon (HFC) blend of difluoromethane (R-32) and pentafluoroethane (R-125), operating at higher pressures than its predecessor R-22 and delivering superior cooling efficiency in modern air handler and heat pump configurations.

Due to the EPA AIM Act phase-down, R-410A production and import quotas are being reduced starting in 2025. This means prices are rising and supply will tighten each year. HVAC contractors and distributors who stock up now will be protected against future shortages. We offer R-410A in 25 lb virgin-sealed cylinders from both Honeywell and other EPA-approved manufacturers.

• GWP: 2,088 | ODP: 0 | ASHRAE Safety Classification: A1
• Best for: Residential central AC, heat pumps, light commercial systems built after 2010
• Available sizes: 25 lb cylinders, pallet quantities, bulk freight orders

R-454B Refrigerant (Opteon XL41) — The Future-Ready R-410A Replacement

R-454B, sold commercially under the Honeywell brand name Opteon XL41, is the EPA-designated primary replacement for R-410A in new residential HVAC equipment manufactured after January 1, 2025. It is a hydrofluoroolefin (HFO)-HFC blend with a Global Warming Potential of just 466 — nearly 78% lower than R-410A — making it fully compliant with the AIM Act phase-down requirements.

If you service or distribute equipment built after 2025, R-454B is now essential inventory. Its thermodynamic properties allow near-drop-in performance in systems designed for it, with improved energy efficiency ratings. Distributors who stock R-454B now will be ahead of demand as the installed base of R-454B systems grows rapidly in 2025 and beyond.

• GWP: 466 | ODP: 0 | ASHRAE Safety Classification: A2L (mildly flammable)
• Best for: New residential HVAC systems manufactured 2025 onward
• Complies with: EPA AIM Act, HFC phasedown regulations

R-32 Refrigerant — High-Efficiency, Lower-GWP Option

R-32 (difluoromethane) is a single-component HFC refrigerant with a GWP of 675 — significantly lower than R-410A. It is the dominant refrigerant in modern mini-split and multi-split systems manufactured by Daikin, Mitsubishi, and other leading OEMs. R-32 offers up to 12% greater energy efficiency than comparable R-410A systems and is increasingly specified in new commercial installations.

• GWP: 675 | ODP: 0 | ASHRAE Safety Classification: A2L
• Best for: Mini-splits, multi-zone systems, commercial VRF systems

R-22 Refrigerant (Reclaimed) — Support for Legacy Systems

R-22, once the industry standard for residential air conditioning, is no longer manufactured or imported in the United States under the Montreal Protocol phase-out. However, millions of HVAC units installed before 2010 still operate on R-22 and require it for servicing and recharging. We supply EPA-compliant reclaimed and recovered R-22 that meets AHRI 700 purity standards, allowing contractors to continue servicing older equipment legally and reliably.

• Note: R-22 is only available in reclaimed form. Virgin R-22 production is banned in the USA.
• EPA 608 certification is required to purchase R-22.

R-404A — Commercial Refrigeration & Low-Temperature Applications

R-404A is a ternary HFC blend (R-125/R-143a/R-134a) widely used in medium- and low-temperature commercial refrigeration, including supermarket display cases, walk-in coolers, ice machines, and food storage facilities. While R-404A is being phased down under the AIM Act due to its high GWP, it remains essential for servicing the large installed base of existing commercial refrigeration equipment across the United States.

• GWP: 3,922 | ODP: 0 | ASHRAE Safety Classification: A1
• Best for: Commercial refrigeration, cold storage, supermarket systems

R-407C — R-22 Retrofit in Commercial Systems

R-407C is an HFC blend formulated as a near-drop-in retrofit replacement for R-22 in commercial air conditioning systems. Unlike R-410A, R-407C operates at similar pressures to R-22, making it a cost-effective retrofit option for commercial buildings looking to extend the life of existing equipment without full system replacement.

• GWP: 1,774 | ASHRAE Safety Classification: A1

R-448A & R-438A — High-Performance R-22 and R-404A Alternatives

R-448A (sold as Solstice N40) is a non-flammable HFO/HFC blend designed as a lower-GWP replacement for R-404A and R-22 in commercial refrigeration. R-438A (MO99) is another widely used R-22 alternative compatible with most existing R-22 system components. Both are available from Smart Refrigerants for contractors managing large commercial retrofit projects.

Frequently Asked Questions — HVAC Refrigerants

Do I need EPA 608 certification to buy HVAC refrigerants?

Yes. Under EPA Section 608 regulations, any technician who purchases refrigerants in containers larger than 2 lbs must hold a valid EPA Section 608 certification. This applies to all HFCs including R-410A, R-454B, R-32, and R-404A. Wholesale distributors who resell to certified technicians must also maintain applicable reseller compliance records.

Can I still buy R-410A refrigerant in 2025?

Yes, R-410A is still legal to purchase for use in servicing existing equipment. The EPA AIM Act phase-down restricts the production and import of R-410A beginning in 2025, but existing systems can still be recharged and serviced with R-410A indefinitely. However, availability is decreasing and prices are rising. We strongly recommend stocking up now while supply remains strong.

What is replacing R-410A in new HVAC equipment?

R-454B (Opteon XL41) is the primary replacement designated for new residential HVAC systems in the United States under the EPA AIM Act. Systems manufactured after January 1, 2025 are required to use lower-GWP refrigerants. R-32 is also increasingly used in mini-split systems and commercial applications due to its lower GWP and superior efficiency.

Is R-22 still available?

R-22 is no longer manufactured or imported in the United States. However, reclaimed and recovered R-22 that meets EPA purity standards remains available and legal for use in servicing existing equipment. We supply certified reclaimed R-22 for contractors maintaining legacy systems. EPA 608 Section A (or Universal) certification is required.

What is the shelf life of refrigerant cylinders?

Refrigerant cylinders have no formal expiration date when stored properly in a cool, dry environment away from direct sunlight and extreme temperatures. Virgin factory-sealed cylinders can be stored for many years without degradation. Always inspect valve seals and cylinder integrity before use.

Do you ship refrigerants to all 50 states?

Yes, we ship to all 50 states via ground and freight carriers. All shipments comply with DOT HAZMAT regulations for compressed gas cylinders. Note that certain refrigerants including R-422B, R-507, and some blends face state-level restrictions in California and New York — please review your specific state’s regulations before ordering.
