Navigating the HVACR Transition: Adapting to A2L Refrigerants in 2025 with First Co

This webinar, presented by ATS SpecTool and First Co, explores the transition to A2L refrigerants within the HVACR industry. It highlights critical changes, opportunities, and adaptations for First Co products.
Key Discussion Points
A2L Refrigerant Transition
The presentation explains the ongoing shift from R-410A to A2L refrigerants-primarily R-454B and R-32. While both are lower-GWP alternatives, their differences and system impacts are discussed in detail. This shift aligns with US Department of Energy initiatives to reduce environmental impact.
First Co Product Adaptations
First Co has redesigned its product lineup-including PTAC units, air handlers, and fan coils-to support the new refrigerants. Updated models are compatible with R-454B, R-32, and legacy R-410A systems (for servicing and replacements). Additionally, a new model numbering system has been introduced for greater clarity in specifications.
ATS Spec Tool Integration
The session showcases how First Co's updated product offerings are seamlessly integrated into the ATS Spec Tool. This tool streamlines the configuration process, offering features like detailed equipment specifications, Revit files, and associated technical documentation.
