A2L

Refrigerant Change

Information and resources to help you prepare for the transition to A2L refrigerants.

Get to Know A2L

As you might already know, our industry will soon switch to new, lower Global Warming Potential (GWP) A2L refrigerants.
As your partner in HVAC, we want to make this change as easy as possible, so we’ve put together this guide for your convenience.

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.

Why

R-454B has the lowest EPA Significant New Alternatives Policy (SNAP) approved GWP for unitary applications of all ASHRAE classified A2L (low-toxicity, mild flammability) refrigerants in the HVAC industry today — much lower than the 700 GWP limits finalized by the EPA.

How

R-454B is a close match to R-410A (the industry-standard refrigerant choice since the early 2010s). This will help limit the level of system or component redesign required. So, while there will be some changes to our products, the look and feel of our R-454B systems will be similar to that of R-410A.

When

NGH has been in the process of redesigning our equipment since 2020 and we are on track to have all products complete and ready for purchase in advance of the 2025 transition date. NGH will be supplying transition details to our customers starting in 2024.

Where

Throughout 2024, you can expect to see a variety of educational opportunities, including new product literature, homeowner literature, webinars, live demos, training videos, in-person training where appropriate, FAQs and more.
