Honeywell Solstice® R-454B Refrigerant is a lower-GWP HVAC refrigerant designed for new air-conditioning and heat-pump equipment specifically engineered and approved for R-454B.

Supplied in a 20 lb cylinder, Honeywell Solstice R-454B is well suited for HVAC contractors, technicians, mechanical contractors, facility teams, and commercial buyers working with newer residential and light-commercial cooling and heating systems.

R-454B was developed as a lower-GWP alternative to R-410A for next-generation HVAC equipment. It offers operating characteristics that allow equipment manufacturers to design systems with capacity and performance characteristics similar to R-410A while substantially reducing refrigerant global warming potential.

R-454B is not a universal or drop-in replacement for R-410A. Always confirm the refrigerant listed on the equipment nameplate and follow the equipment manufacturer's installation and service procedures.

R-454B Refrigerant for New HVAC Systems

R-454B is increasingly used in newer residential and light-commercial air-conditioning and heat-pump systems as the HVAC industry transitions away from higher-GWP refrigerants such as R-410A.

Honeywell designed Solstice 454B for comfort cooling and reversible heating applications, including equipment such as residential air conditioners, heat pumps, commercial packaged systems, and certain compatible chillers.

R-454B falls below the 700 GWP threshold established for many categories of new residential and light-commercial air-conditioning and heat-pump equipment.

For HVAC contractors installing or servicing equipment designed for R-454B, keeping the correct refrigerant available is increasingly important as more R-454B systems enter the installed equipment base.

What Is Honeywell Solstice R-454B?

Solstice® 454B is Honeywell's branded R-454B refrigerant.

R-454B is a zeotropic blend consisting of R-32 and R-1234yf. The combination provides substantially lower global warming potential than R-410A while maintaining operating characteristics suitable for modern comfort-cooling and heat-pump equipment engineered around R-454B.

R-454B contains approximately:

68.9% R-32 and 31.1% R-1234yf.

The refrigerant has zero ozone depletion potential and is classified as A2L under ASHRAE Standard 34.

Because it is a refrigerant blend, technicians should use current R-454B pressure-temperature data and follow manufacturer procedures when charging and servicing equipment.

R-454B vs. R-410A

R-454B is commonly described as a next-generation alternative to R-410A for new HVAC equipment, but the two refrigerants are not interchangeable.

R-410A has an EPA GWP reference value of 2,088, while R-454B has a value of 465. This gives R-454B substantially lower refrigerant-related global warming potential.

The safety classifications also differ.

R-410A is classified as A1, while R-454B is classified as A2L, meaning R-454B is mildly flammable and requires equipment, installation practices, service tools, and safety procedures designed around A2L refrigerants.

Technicians should never select refrigerant based only on pressure similarity or cooling application.

Always use the refrigerant specified by the equipment manufacturer.

Can R-454B Be Used in an Existing R-410A System?

R-454B should not be used as a drop-in replacement or field retrofit refrigerant for an existing R-410A system unless the equipment manufacturer specifically provides an approved procedure for that equipment.

R-454B systems incorporate design and safety considerations associated with A2L refrigerants. These can include refrigerant-charge limitations, electrical requirements, leak-mitigation provisions, installation standards, service procedures, and component specifications.

An existing R-410A system was not necessarily designed to meet those R-454B requirements.

If an equipment nameplate specifies R-410A, continue to follow the manufacturer's instructions for that system rather than replacing the refrigerant with R-454B.

Why R-454B Is Used in New HVAC Equipment

R-454B has become an important refrigerant for new HVAC equipment because it combines a significantly lower GWP with performance characteristics suited to modern air-conditioning and heat-pump designs.

Honeywell developed Solstice 454B to provide characteristics close to R-410A while allowing manufacturers to move below current GWP limits for many new comfort-cooling applications.

Its primary advantages for properly designed equipment include substantially lower GWP than R-410A, zero ozone depletion potential, compatibility with common POE lubricants, and operating characteristics suitable for residential and light-commercial HVAC equipment.

Actual system capacity, efficiency, energy consumption, and performance depend on the specific equipment design and operating conditions.

R-454B Is an A2L Refrigerant

R-454B carries an A2L safety classification, which means it is classified as lower toxicity with mild flammability.

This distinction is especially important for technicians who have historically worked primarily with A1 refrigerants such as R-410A.

R-454B equipment must be installed and serviced according to applicable codes, standards, manufacturer instructions, and A2L-specific requirements.

Technicians working with R-454B should use tools and service equipment appropriate for A2L refrigerants and follow requirements concerning ventilation, ignition-source control, leak detection, refrigerant recovery, cylinder handling, and personal protective equipment.

Always review the Honeywell Safety Data Sheet before handling Solstice R-454B.

20 lb Honeywell Solstice R-454B Cylinder

The 20 lb Honeywell Solstice R-454B cylinder provides a practical refrigerant quantity for professional HVAC contractors and service companies working with approved R-454B equipment.

Before using the refrigerant, verify the equipment nameplate, Honeywell product label, cylinder condition, Safety Data Sheet, service connection, required refrigerant charge, and manufacturer service instructions.

Never assume that tools, hoses, recovery equipment, or charging procedures used with an A1 refrigerant are automatically appropriate for an A2L refrigerant.

Who Can Purchase R-454B Refrigerant?

Federal refrigerant sales restrictions apply to R-454B sold for stationary air-conditioning and heat-pump equipment.

For stationary HVAC applications, purchasers generally must be EPA Section 608 certified technicians, qualifying employers or authorized representatives of certified technicians, qualifying refrigerant resellers, or other purchasers permitted under applicable EPA requirements.

Section 609 certification applies to motor-vehicle air-conditioning applications and does not by itself authorize the purchase of refrigerant intended for stationary HVAC equipment.

Buyers should verify all applicable federal, state, local, and destination requirements before ordering.
