The R-454B shortage is creating real challenges for contractors—and ACCA is here to support you. We’ve launched the R-454B Shortage Resource Center to give you quick access to trusted information, A2L safety training, FAQs, and a place to ask your most pressing questions.
We’re working with manufacturers and regulators to get answers and push for greater transparency. This hub will be updated regularly to reflect the latest insights and resources.
Thank you for your continued professionalism. ACCA is committed to helping you navigate this challenge safely and effectively.
Sincerely,
Eddie McFarlane
ACCA Chair
