The A2L Refrigerant Transition: A Guide For HVAC Distributors

The HVAC industry is entering a transformative phase with the mandated transition from high-GWP refrigerants like R410A to low-GWP A2L refrigerants such as R454B. As a distributor, you’ll play a key role in ensuring this transition is seamless for contractors, customers and your own operations. Here’s what you need to know about this shift, its implications on your business and how GE Appliances Air & Water Solutions is here to support you.

Background on the Refrigerant Transition

The move to A2L refrigerants is driven by environmental goals to lower the HVAC industry’s carbon footprint. With up to 79% less Global Warming Potential (GWP) compared to R410A, A2Ls align with federal regulations like the American Innovation and Manufacturing Act.

For distributors, this transition means updating inventories and educating customers on new products and technologies. Staying informed on industry-wide changes and those specific to your manufacturer partners will ensure you can guide contractors effectively.

Key Considerations for Distributors

Your role as an intermediary between manufacturers and contractors introduces both challenges and opportunities. By understanding the key milestones, preparing your inventory and equipping your team with the right tools and training, you’ll be set for what’s to come.

Product Inventory Management

  • Phase-Out of R410A: Starting January 1, 2025, no new equipment utilizing R410A may be manufactured or shipped into the United States. Beginning January 1, 2026, R410A split systems can no longer be installed in new projects, with limited exceptions for repair scenarios. Packaged units can continue to be installed through the end of 2027.

  • Stocking A2L-Compatible Equipment: Over the course of this transition, you will likely need to carry a mix of R410A and A2L inventory to suit your customer’s needs. It is also important to let them know when products become available. Transition timelines for GE’s R454B products include availability starting late 2024 for ducted systems and early 2025 for ductless units.

Safety and Training

A2L refrigerants are mildly flammable, requiring enhanced safety measures. GE Appliances Air & Water Solution’s Learning Academy offers training tailored for handling A2Ls, focusing on leak detection, proper equipment use and compliance with evolving standards​.

Tools and Resources

Distributors will need to provide guidance on updated tools, such as A2L-approved recovery machines, leak detectors and refrigerant tanks. Many of these are already compatible with most equipment purchased in recent years​.

What Distributors Can Expect from GE Appliances

The A2L transition is a widespread change for the industry. GE Appliances is committed to making the process as smooth as possible for distributor customers by offering products designed for seamless integration and easy serviceability. Here’s what to look out for in the new GE systems:

GE Ducted Systems

  • Improved Efficiency: R454B models offer higher SEER2 ratings and increased cooling capacity. Enhanced features, like 45-degree service valves and braze-less tubing connections, make installation faster and more reliable. There is also a new polymer base and top for 20+ SEER2 inverter models.

  • Advanced Components: New air handlers and evaporator coils include factory-installed refrigerant detection sensors for added safety and compliance​.

  • Multi-Refrigerant Air Handlers and Evaporator Coils: These leave the factory R410A-ready but can be converted one-time in the field to be used with R454B using the required accessories, simplifying the transition between refrigerants.

  • Side-Discharge Connect Series:

  • ENERGY STAR® performance

  • Compatible with most 24V thermostats, no proprietary controls required

  • Small footprint, with the smallest model having a depth of only 17 1/8" and low clearances: 4" rear / 14" front

  • Mechanical or brazeless connections

  • Dual Fuel Rated

  • AHRI ratings and compatible with the GE family of indoor units (air handlers, furnaces, evaporator coils)

GE and Haier Ductless Systems

  • Versatile Compatibility: Mix-and-match compatibility with various indoor units ensures flexibility for contractors and end-users.

  • Higher Efficiency: More rebate-qualifying products across all series.

  • Enhanced Features: Built-in Wi-Fi compatibility across all models, ensuring SmartHQ™ Home and SmartHQ™ Service integration. A new communication wire allows for over-the-air (OTA) updates to the outdoor unit via the indoor unit from the SmartHQ Home App.

GE PTAC/VTAC

  • New Zoneline Units: PTACs and VTACs are now available with R454B refrigerant, so you can continue to offer best-in-class performance without a hitch.

  • Advanced Technology: Inverter technology and a variable-speed compressor give guests more comfort, more often with the new Zoneline Perfect Control PTAC units. The variable-speed compressor is one size fits all for models of 4,000 to 15,000 BTUs.

  • Wi-Fi Ready: Zoneline Perfect Control PTACs and Zoneline VTAC units offer built-in Wi-Fi and SmartHQ management capabilities.

Embrace the Change with Confidence
