Refrigerant 454B and the Future of HVAC Refrigerants

Refrigerants are a critical component of modern HVAC systems, enabling the heat transfer process that allows commercial and industrial facilities to maintain comfortable, controlled environments. As environmental regulations continue to evolve, refrigerants are changing to meet updated efficiency and compliance standards. One of the newer refrigerants entering the market is Refrigerant 454B.

For Michigan businesses, understanding refrigerant options and how they impact HVAC systems is essential for long-term planning, regulatory compliance, and operational reliability.


Refrigerant 454B is a lower global warming potential (GWP) refrigerant developed as an alternative to older, higher-GWP refrigerants historically used in HVAC systems. It is being introduced in newer equipment designs as the industry transitions toward refrigerants with reduced environmental impact.

As part of this transition, 454B is expected to play an increasing role in future commercial HVAC applications, particularly in new installations and equipment replacements designed to meet updated regulatory requirements.


Refrigerants serve as the working fluid within HVAC systems, allowing heat to be absorbed, transferred, and released through a continuous cycle of compression and expansion. This process enables both cooling and heating functions in a wide range of commercial HVAC equipment.

Common HVAC applications that rely on refrigerants include:

  • Commercial air conditioning systems
  • Rooftop units and split systems
  • Chillers and cooling equipment
  • Heat pump systems

Each HVAC system is engineered for a specific refrigerant type, making proper handling, storage, and servicing essential for performance and safety.


Over the years, refrigerants have evolved to address environmental concerns and regulatory changes. Many legacy refrigerants are now regulated or being phased down, creating new challenges for facilities operating older HVAC equipment.

Michigan businesses may face:

  • Limited availability of older refrigerants
  • Increased costs for regulated refrigerants
  • Compliance and documentation requirements
  • Planning considerations for system upgrades

Understanding these changes allows businesses to take a proactive approach to refrigerant management rather than reacting to shortages or regulatory deadlines.


Refrigerant Services supports commercial and industrial customers across Michigan by providing responsible refrigerant handling solutions that align with current regulations. Our services are designed to help businesses manage refrigerants safely and efficiently throughout system maintenance, upgrades, and decommissioning.

Our refrigerant services include:

  • Refrigerant recovery and removal
  • Recycling services
  • Refrigerant exchange and buyback programs
  • Safe handling and transport
  • Support for transitioning to compliant refrigerants

These services help reduce environmental impact while supporting operational continuity.


Facilities operating older HVAC systems often need to remove outdated or surplus refrigerants during equipment upgrades, retrofits, or demolition projects. Proper recovery and recycling are critical to preventing improper disposal and ensuring regulatory compliance.

Refrigerant Services helps Michigan businesses:

  • Safely remove old or excess refrigerants
  • Prepare systems for new equipment or refrigerant changes
  • Maintain compliance with environmental standards
  • Reduce waste and improve sustainability efforts

Recycling refrigerants helps extend their usable life while reducing the need for new production.


As newer refrigerants such as Refrigerant 454B become more widely adopted, businesses may need support transitioning from older refrigerants. This process typically involves recovering existing refrigerants and coordinating with HVAC service providers to ensure compatibility with new equipment.

Refrigerant Services works with HVAC contractors and facility teams to support smooth refrigerant transitions while maintaining safety and compliance.


Refrigerant Services is committed to helping Michigan businesses navigate refrigerant changes with confidence. From recovery and recycling to exchange and compliant refrigerant solutions, our team provides reliable support for HVAC systems of all sizes.
