R454B consists of 68.9% R32 and 31.1% R1234yf. Its A2L classification means lower toxicity with mild flammability, so equipment design and service procedures must account for A2L requirements.
R454B Refrigerant Applications
HVAC professionals use R454B in compatible equipment specifically designed, listed, or manufacturer-approved for this refrigerant.
Typical applications may include:
- Residential air-conditioning systems designed for R454B
- Light-commercial air-conditioning systems
- Heat-pump systems
- Unitary HVAC systems
- Split-system air conditioners
- Certain compatible chillers
- Certain industrial process air-conditioning applications
- Other equipment specifically designed and approved for R454B
Before selecting or charging R454B, always verify the equipment manufacturer’s refrigerant specification, charge requirements, A2L safety requirements, and applicable regulations.

R454B for Air Conditioning and Heat Pumps
For example, HVAC professionals use R454B in new residential and light-commercial air-conditioning and heat-pump equipment engineered for this refrigerant.
R454B provides a substantially lower GWP than R410A while offering operating characteristics suitable for modern HVAC equipment specifically designed around R454B.
In addition, its GWP of 465 is below the current U.S. 700-GWP threshold that applies to many residential and light-commercial air-conditioning and heat-pump systems.
However, technicians should always follow the equipment manufacturer’s installation, refrigerant charge, leak-detection, ventilation, and service requirements.
R454B Is an A2L Refrigerant
R454B carries an A2L safety classification, meaning it has lower toxicity but is mildly flammable.
Therefore, technicians should use appropriate A2L-compatible tools, equipment, and service procedures.
Important considerations may include:
- A2L-compatible service tools
- Proper ventilation
- Refrigerant leak detection where required
- Control of ignition sources
- Manufacturer-specified charge limits
- Approved recovery equipment
- Proper storage and transportation procedures
- Applicable building and mechanical codes
- Equipment-specific installation instructions
Do not handle R454B exactly the same way as an A1 refrigerant such as R410A.
EPA’s SNAP approval for R454B includes specific use conditions associated with its A2L characteristics.
R454B and R410A Systems
R454B is widely used as a lower-GWP alternative to R410A in new equipment designs. However:
R454B is not a universal direct drop-in replacement for R410A.
Do not remove R410A from an existing system and simply charge it with R454B unless the equipment manufacturer specifically approves that conversion.
Important differences may involve:
- A2L flammability classification
- Refrigerant charge quantity
- System controls
- Leak-detection requirements
- Compressor design
- Expansion devices
- Electrical components
- Ventilation and mitigation requirements
- Equipment certification and labeling
Therefore, technicians should use R454B only in equipment specifically designed, listed, or manufacturer-approved for this refrigerant.
Chemours specifically positions R454B as an R410A alternative for new equipment designs, rather than as a universal drop-in retrofit refrigerant.
R454B Charging and Service Considerations
Because R454B is a refrigerant blend, technicians should follow equipment manufacturer instructions when charging a compatible system.
For applicable equipment, technicians generally charge R454B in the liquid phase to help maintain the intended blend composition.
Always follow the equipment manufacturer’s specified charge quantity, commissioning procedures, cylinder instructions, and A2L safety requirements.
OEM R454B service guidance specifies liquid-phase charging for compatible systems.

U.S. Refrigerant Purchase Requirements
R454B sold in cylinders for stationary air-conditioning and refrigeration use is subject to EPA refrigerant sales restrictions.
For stationary systems, EPA generally limits refrigerant purchases to appropriately Section 608-certified technicians or qualifying employers/authorized representatives that employ certified technicians. Refrigerant sellers also have purchaser-verification and recordkeeping responsibilities.
Important Use Information
Qualified HVAC professionals should handle, store, recover, charge, and use R454B in accordance with applicable regulations, equipment manufacturer requirements, A2L safety procedures, and established service practices.
Always confirm that the equipment is specifically designed or approved for R454B before use.
For current information about approved R454B applications and use conditions, refer to the U.S. EPA SNAP refrigerant guidance.
