An Overview of A2L Changes
What
With the passing of the 2020 American Innovation and Manufacturing (AIM) Act, the Environmental Protection Agency (EPA) has finalized regulations that limit the Global Warming Potential (GWP) of air-conditioning refrigerants to a maximum of 700 starting in 2025. In compliance with this change, NGH has selected R-454B as our refrigerant in all new residential and manufactured housing products.
