EPA Technology Transition Rule: Final Ruling Overview

The EPA Transition Rule plays a crucial role in phasing down hydrofluorocarbons (HFC) in products like HVAC systems. Enacted through the AIM Act (American Innovation and Manufacturing) and signed by the EPA, this regulation sets the stage for a significant shift in reducing HFC usage. 

The EPA Technology Transition Rule addresses environmental concerns associated with refrigeration and cooling systems. Key provisions include distinguishing between "products" and "systems," specifying components covered by the rule, and deadlines for compliance. 

Who Is Affected? 
Anyone involved in assembling, contracting, owning, or operating a system is subject to the rule. For split systems, compliance responsibility lies with the entity in the field, not the manufacturer. 

Important Deadlines 

  • 1/1/2025: Residential and commercial air conditioners and heat pumps must have a GWP less than 700.
  • 1/1/2026: Split system air conditioners and heat pumps must be field charged by this date. 
  • 1/1/2027: Data Centers must adhere to a GWP less than 700

Canadian Impact 
Canadian HVAC professionals face unique challenges, including the potential allowance of commercial A2L products and updates to building codes. Staying engaged with local code officials is essential for effectively managing these changes. 

Urgent Alignment and Key Takeaways 
As we navigate this refrigeration transition, aligning products with designated GWP limits within specified timeframes is crucial. Ensuring compliance with the EPA's regulations is not just a box to tick; it's the key to maintaining smooth business operations in this industry.
