AIM Act Compliance Guide
Understanding EPA refrigerant regulations for commercial HVAC installations
What is the AIM Act?
The American Innovation and Manufacturing (AIM) Act of 2020 directs the EPA to phase down the production and consumption of hydrofluorocarbons (HFCs) by 85% over the next 15 years. This directly impacts commercial HVAC refrigerants.
For commercial HVAC contractors, this means new installations should use low-GWP (Global Warming Potential) refrigerants like R32 and R454B instead of legacy R410A.
R32
Low-GWP refrigerant. AIM Act compliant. GWP of 675 — 68% lower than R410A. Used in Daikin, Goodman and ACiQ packaged units.
R454B
Low-GWP blend refrigerant. AIM Act compliant. GWP of 466 — 78% lower than R410A. Used in Trane and Carrier packaged units.
R410A
High-GWP refrigerant being phased down. GWP of 2,088. Still legal for existing systems but new installations should transition to R32/R454B.
