The AHR Expo 2025, held in Orlando, was more than an industry gathering. With over 50,000 professionals in attendance, it reflected the direction the HVACR sector is headed: toward low-carbon systems, smarter connectivity, and more serious integration between hardware and control logic.
For companies operating in the hydronic space, especially those tuned into heat pumps, this year’s event validated strategic direction. For Polar Air, the event confirmed that our core direction, hydronic systems built for heat pump efficiency and system flexibility, is exactly what the market demands.
Major trends & insights from AHR 2025 in North America
01 Decarbonization without compromise
Decarbonization was no longer a side note. it was the baseline. Throughout the expo, seminars and product platforms alike focused on lowering emissions through system electrification and tighter integration between equipment and building performance targets.
The shift to all-electric building systems is driving a new standard in HVAC design. Hydronic solutions are gaining renewed attention for their flexibility in decarbonizing infrastructure, especially when paired with heat pumps or solar thermal collectors.
Regulatory conversations, including the transition from refrigerants such as R-22 to R-32 and R-454B, which are emerging as primary replacements, as well as incentives from the IRA, featured prominently in panels and sessions.
02 Heat pumps & eco-friendly water heating
Heat pumps took center stage and for good reason. The industry’s shift toward electrification and low-carbon systems isn’t just talk anymore. It’s happening fast, and hydronic solutions are right in the middle of it.
Energy efficiency continues to lead specification decisions, but there’s a new layer: delivering that efficiency through water-based distribution that supports decarbonized generation methods.
The expo showed growing momentum around air-to-water heat pumps, particularly in residential and commercial applications. This trend aligns strongly with the capabilities of modern fan coil systems, which are designed to operate at lower water temperatures without compromising occupant comfort.
As more systems are engineered around water at 35–45°C rather than the old 60–70°C baseline, fan coils must be optimized for performance within those constraints. Something that’s becoming a design requirement rather than a feature.
This trend reinforces the importance of hydronic systems that can perform at low lift conditions, with modulating fans, tight temperature control, and stable output across a wide delta-T. As heat pump infrastructure becomes more common, these characteristics will move from “nice to have” to essential.
03 Smart and connected technology
Connected controls and system-level data were everywhere. Installers, engineers, and facility operators are looking for equipment that’s transparent, easy to commission, and compatible with broader building automation strategies.
The focus is shifting from simply being “smart” to being interoperable — open protocols, accessible diagnostics, and native compatibility with BACnet, Modbus, and cloud gateways. This isn’t about flashy dashboards anymore. It’s about making HVAC hardware accountable, measurable, and adaptive to real conditions.
04 Industry collaboration and workforce development
The labor shortage in the HVAC industry was one of the most pressing and recurring themes at AHR 2025. Across panels, technical talks, and informal conversations, the message was the same: there simply aren’t enough qualified professionals to meet the growing demands of modern HVAC systems.
With aging technicians retiring and too few entering the trades, the industry is facing a gap not just in numbers, but in technical readiness. Today’s systems are more complex, more connected, and more tightly regulated. But most installers and techs are still navigating a backlog of training, certification requirements, and increasingly tight timelines.
This is forcing a rethink across the value chain. Manufacturers, engineers, and contractors are looking for products that reduce install time, minimize on-site configuration, and offer clear, accessible diagnostics. If a system can’t be commissioned quickly by a mid-level tech, it’s going to be a bottleneck.
This is exactly why plug-and-play logic, factory preconfiguration, and intuitive controls cannot be classed as premium features. They must be standard. Systems need to work out of the box, adapt to imperfect field conditions, and be serviceable by technicians who may not be specialists in every part of the system.
The industry is also leaning harder into collaborative training: co-branded education programs, remote learning platforms, and on-demand technical support. Not just to fill the gap, but to futureproof against a wave of electrification and control integration that will only increase the complexity of mechanical systems.
At AHR, there was strong consensus: HVAC products must be designed for the workforce we have today, not the one we wish we had. That means fewer tools, faster setup, clearer interfaces, and smarter fault handling. It also means cross-industry alignment to make sure installers, specifiers, and manufacturers are speaking the same technical language from project start to closeout.
Conclusion: HVAC is moving fast
AHR Expo 2025 made one thing clear: the HVAC industry isn’t inching forward, it’s moving fast. Decarbonization targets are real. Low-temperature system design is now expected, not optional. And connected, easy-to-service equipment is the new standard.
For those of us in the hydronic space, that’s not a disruption. It’s validation. Polar Air has been building low-temperature-ready fan coil systems with smart control compatibility and installer-first design for years. The conversations in Orlando reinforced what we’ve known all along: flexible, efficient, and future-focused hydronic systems are central to where HVAC is going next.
We’re already looking ahead to AHR 2026 in Las Vegas (February 2–4). If you’re planning to be there and want to talk about how we can help futureproof your hydronic HVAC strategy, contact us and let’s make it happen. Whether you’re designing around heat pumps, looking to simplify field commissioning, or just need a partner who understands where the market is heading, we’re ready.
