R-444A and R-456A are emerging as practical options for direct replacement in mobile A/C systems, but achieving expected performance in retrofit applications requires more than a simple drop-in approach. This session will provide a field-focused perspective on what it takes to optimize system performance when retrofitting vehicles with next-generation refrigerants. The discussion will briefly revisit key system fundamentals—including fitting assemblies, service procedures, and equipment considerations—before shifting to real-world implementation. Drawing on recent laboratory and field testing, attendees will gain insight into the system-level adjustments, service practices, and performance considerations required to deliver consistent cooling across ICE, hybrid, and EV platforms. The session will also address common objections, control-related challenges, and misconceptions associated with “direct replacement” refrigerants, equipping shop owners and technicians with practical guidance as R-444A and R-456A become more widely available in the aftermarket.

8:30-9:00 a.m.
Speaker
Sherie Dooly-Jones
STEINBAUER Engineering
Sherie Dooly-Jones grew up in Central Victoria, Australia, before spending fifteen years living and working across Europe — an experience that shaped both her global outlook and her deep appreciation for the people who work the land and keep heavy equipment moving. In 2008, she opened the STEINBAUER North America office, spending the next fifteen years travelling between Europe and the US before making the permanent move in 2024.
In her role at STEINBAUER, Sherie travels to approximately twenty states each year, working directly with farmers, contractors, service shops, and independent mobile repair technicians who depend on heavy equipment — giving her a ground-level view of what data access restrictions mean in the real world, not just in policy documents. That same firsthand experience sparked her interest in Right to Repair in 2019, and she has followed the issue closely ever since, delivering talks and presentations on the subject across the industry.

Behind every truck that can’t be diagnosed is a fleet manager losing uptime. Behind every job turned away is a customer who bought a machine expecting to have options when it needs repair. The Right to Repair debate affects everyone in the chain — the operators and fleet owners who buy the equipment, the service providers who maintain it, and the trainers and businesses who support the industry around it.
This session takes a solution-based look at where diagnostic data access stands today — the legislation, the landmark John Deere FTC settlement, and the real cost of the current model across the service chain — and then shifts the conversation to where it needs to go: a middle ground that works for everyone.
If you’re a service provider, trainer, or executive trying to understand where this issue is headed and how your organization should be positioned, this session gives you the framework and opens the floor for input.
