A2L Ready

Prepare for the A2L Refrigerant Transition with our HVAC Dealer & Contractor Resource

As the HVAC industry moves towards more environmentally friendly solutions, the upcoming A2L refrigerant transition mandated by the AIM Act represents a significant shift. A2L refrigerants, with their lower global warming potential, are part of the effort to reduce greenhouse gas emissions. This transition will impact how HVAC systems are installed, maintained, and serviced.

What Does the A2L Transition Mean for You?

Starting in 2025, the EPA’s AIM Act requires the phase-down of high-GWP refrigerants like R-410A and the introduction of mildly flammable, low-GWP A2L refrigerants. For HVAC dealers and contractors, this change will affect:

  • Product Selection: New systems will be designed for A2L refrigerants, requiring updates to product inventories.
  • Safety Standards: A2L refrigerants are classified as mildly flammable, meaning new safety protocols and certifications are necessary for proper handling and installation.
  • Tools and Supplies: Contractors will need specific tools and equipment designed to safely work with A2L systems.
  • Customer Education: You’ll need to educate your customers about these changes, including the environmental benefits and how this transition impacts system costs and maintenance.
