“R-454B: What It Is and Why Cool Air M.D. Is Ahead of the Game”

What Is R-454B and Why Does It Matter to You?

Starting in 2025, new HVAC systems will use R-454B, a low-GWP A2L refrigerant designed to reduce environmental impact and meet EPA guidelines. While this change is great for the environment, it also requires new tools, new training, and strict safety codes.

The problem?Many companies aren’t ready — and some won’t be for months.

At CoolAir M.D., we’ve already stepped up.We’ve trained our team, updated our procedures, and we’re already installing and servicing R-454B systems safely, efficiently, and up to code.
