Technician Guide to Lennox Low GWP Transition

You can count on Lennox to make decisions that are good for dealers, good for homeowners, and good for the environment. That’s why we’ve updated our entire product lineup to use 2025 Compliant Refrigerants R-454B for whole-home systems and R-32 for ductless mini-split systems. With substantially lower global warming potential (GWP) than previous refrigerants, these alternatives comply with updated EPA regulations and are formulated to provide excellent, reliable performance for years to come.

Lennox is here to provide support and resources to make these 2025-compliant systems easy to sell, install, and service.
