A shortage of R-454B refrigerant is currently impacting the HVAC industry due to increased demand and supply chain issues. This shortage is primarily caused by the EPA's mandated phase-out of R-410A, leading to a surge in demand for R-454B, which is being adopted as a replacement. Production and distribution challenges, along with supply chain disruptions, have further exacerbated the situation.
