Quotes from the episode: "It's a solution to a problem people don't even know they have."   "Compliance is no longer just paperwork. It's becoming part of how smart contractors protect margin and keep access to refrigerant."   "What GPS did for traffic, shared HVAC documentation could do for equipment history, refrigerant tracking, and accountability."   In this episode of the Building HVAC Science podcast, Bill Spohn talks with Adam Dykstra of FM Hero about a part of the HVAC industry that often gets overlooked until it becomes a serious problem: refrigerant compliance, documentation, and tracking. Adam explains how FM Hero was built to help technicians, contractors, equipment owners, manufacturers, and eventually wholesalers manage the growing web of regulations tied to refrigerants, including Section 608, the AIM Act, and a patchwork of state-level rules. What sounds at first like a compliance tool turns out to be something bigger: a shared documentation platform that follows equipment, cylinders, and service history across the whole ecosystem.   Adam introduces the idea of the "Heroverse," a connected data environment where technicians can scan a unit nameplate, log service actions, track refrigerant movement, and build a portable service history over the course of their careers. Contractors gain visibility into field activity, equipment owners gain documentation they may now be legally required to have, and even manufacturers can see anonymized service history on their equipment in the field. The system is designed to fit real technician workflow rather than add paperwork, and the technician version is free to use.   The big takeaway is that refrigerant tracking is no longer just a back-office nuisance or an abstract EPA concern. With lower charge thresholds, more aggressive state rules, and likely future refrigerant supply constraints, documentation and recovery practices are becoming both a compliance issue and a business opportunity. Adam makes the case that contractors who get ahead of this can protect customers, strengthen retention, and even create a new profit center, all while helping reduce waste and preserve refrigerant supply for the future.   Adam's LinkedIn:https://www.linkedin.com/in/adam-dykstra/ FM Hero website: https://www.fmhero.com/FM Hero resource CenterL https://www.fmhero.com/resource-center/ Android app:https://play.google.com/store/apps/details?id=com.fmhero.mobile&hl=en iOS app: https://apps.apple.com/us/app/fmhero/id1570918942 This episode was recorded in March 2026.

In this episode of the HVAC School Podcast, host Bryan sits down with Jeff Staub, Director of OEM Sales for Danfoss North America, to explore one of the most rapidly evolving frontiers in the HVAC and refrigeration world: thermal management for AI data centers. With nearly 30 years of industry experience spanning technical support, application engineering, and product development, Jeff brings deep expertise on how the explosive growth of AI chip technology is reshaping data center cooling architecture — and creating major new opportunities for HVAC professionals, contractors, and facility managers alike. A central theme of the conversation is heat recovery — specifically, how the enormous amounts of heat generated by high-density GPU chips in modern data centers can be captured and repurposed rather than simply rejected into the atmosphere. Jeff explains that while heat recovery itself is not a new concept (supermarkets have used reheat coils and heat reclaim for decades), its application in AI data centers presents fresh challenges and possibilities. The heat coming off liquid-cooled server chips typically runs around 90 to 100 degrees Fahrenheit — useful, but not immediately at the temperature needed for most end applications like domestic hot water or space heating. Boosting that heat using heat pumps or feeding it into district energy systems, boiler pre-heat loops, vertical farms, or multifamily housing developments are among the most promising strategies being explored around the world. Jeff highlights a significant contrast between Europe and the United States in how heat recovery is being adopted. In Europe, where district energy networks are widespread, data centers can plug directly into community heating infrastructure — and projections suggest that 80% of European data centers will incorporate heat recovery in the near future. In the US, the picture is more fragmented: while opportunities exist at universities, hospitals, urban mixed-use developments, and facilities co-located with nuclear power plants, the economics are trickier. Key sticking points include who owns the capital expenditure for heat recovery modules and heat pumps, and who ultimately benefits from the recovered heat. Bryan and Jeff discuss how innovative ownership models — with landlords, municipalities, or co-tenants sharing infrastructure — are beginning to unlock these opportunities, and how co-generation arrangements with power stations present exciting long-term potential. The episode wraps up with highly practical guidance for HVAC contractors and facility managers looking to break into the data center space. Jeff encourages technicians not to be intimidated: the fundamentals of vapor compression, chiller systems, and fluid flow that HVAC professionals already know transfer directly to data center work. The key additions are familiarity with large centrifugal and screw compressors, variable frequency drives on pumps, glycol loop management, and central distribution unit (CDU) architectures. Bryan emphasizes that the boundary between HVAC and plumbing will continue to blur as secondary fluid pumping becomes more prevalent — and that staying curious and investing in ongoing training (through manufacturer programs like Danfoss Learning, Carrier University, and others) is the best way to ride this wave rather than get left behind. Both hosts agree: AI data centers are not going away, and the technicians who keep them cool will be indispensable. Topics Covered The evolution of data center cooling — from direct vapor compression on chips, to air-conditioned server rooms (CRAC units), to today's liquid cooling and chiller-loop architectures Why AI GPU chips generate unprecedented heat densities, with individual server racks approaching 250 kW to 1 MW of heat output What heat recovery means in the data center context: capturing hot water (90–100°F) off chip cooling loops instead of rejecting it to outdoor air The concept of 'heat quality' — why low-temperature waste heat is abundant but difficult to use directly, and how heat pumps solve the temperature-lift challenge Real-world heat recovery applications: district energy systems, boiler pre-heat, vertical farms, multifamily housing, hospitals, and universities Europe vs. the US: why district energy adoption makes heat recovery far more common in European data centers, and what the US can learn Business model challenges: who pays for heat recovery infrastructure, and how co-location, municipal incentives, and landlord ownership models can unlock value Co-generation opportunities: feeding recovered heat back into steam turbines at co-located nuclear or power plants How heat recovery makes heat pump technology more viable by raising the source temperature and reducing compression ratio Danfoss's role in data center thermal management — from compressors and drives to plate heat exchangers, CDU flow control, and prepackaged heat recovery modules Refrigerant transitions and what they mean for data center cooling (R-410A to R-454B, CO2 transcritical systems, potential two-phase refrigerant direct-to-chip cooling) The convergence of HVAC and plumbing trades in a world of secondary fluid pumping and isolated refrigerant charges Absorption chiller technology as a potential future use case for low-grade waste heat Advice for contractors: how existing chiller and refrigeration skills translate to data center work, and what new competencies to build Career and training resources: Danfoss Learning, manufacturer universities (Carrier, Trane, McQuay), and leveraging AI tools for self-education The importance of redundancy and uptime in mission-critical data center environments — and what that means for service response expectations   Learn more about Danfoss at danfoss.com/learning Have a question that you want us to answer on the podcast?

Recorded live on the third day of the AHR Expo 2026 in Las Vegas, Nevada, this episode of HVAC School brings together host Bryan and longtime friend of the show Tony Gonzalez, Director of Training at Fieldpiece Instruments. The conversation kicks off with some light-hearted banter about trade show survival tips — including the classic trick of hanging around near closing time to score free gear from exhibitors who don't want to ship anything home. Tony, who spent much of the show working the Fieldpiece booth, shares what it's like to be on that side of the expo floor, while Bryan admits he stopped by the booth but somehow managed to avoid saying hello. One of the highlights of the episode is a hands-on look at Fieldpiece's brand new analog manifold gauge set — a surprise addition to their lineup. Bryan gives his first impressions live on the mic, noting the heavy-duty build quality, four-port design, dual-scale display for popular refrigerants including R-22, R-32, R-454B, and R-410A, and high-pressure ratings. The standout feature that catches Bryan off-guard is a built-in pressure marker ring — what Tony jokingly calls a "fidget spinner" — that allows techs to mark a pressure point on the gauge dial during standing pressure tests, replacing the old wax pen or Sharpie workaround. Bryan makes a compelling case for why every truck should carry a set of analog gauges as a reliable backup, especially for dirty systems, long-term standing pressure tests, or situations where digital probes or batteries fail. Tony shifts the conversation to something he's deeply passionate about: Fieldpiece's commitment to tackling two of the biggest challenges facing the HVAC industry today — low-quality workmanship in the field and the growing skills gap as experienced technicians retire. Fieldpiece has launched a formal School Partnership Program, developed after extensive conversations with trade school directors and union leaders to understand their real needs. The program offers in-person support, supplemental training materials focused on best practices, prizes for top graduates, tools for labs and classrooms, and student discounts. Tony also unveils Fieldpiece's mobile training trailer — a fully-equipped 35-foot rig with live HVAC equipment, including a variable-speed heat pump and furnace — designed to bring hands-on training directly to contractors, distributors, and schools. Bryan passionately echoes the importance of repetitive, hands-on practice, arguing that reading books or watching videos will never replace actually pulling vacuums and executing best practices over and over again. The episode wraps up with Tony sharing details about Fieldpiece's revamped rewards program, where technicians and contractors can earn points by registering products, attending events, and completing free courses on Fieldpiece University — Fieldpiece's online learning platform offering continuing education credits. Bryan encourages small contractors to leverage Fieldpiece University as the backbone of an in-house apprenticeship program without needing a big budget. Tony also teases some exciting future developments, including a new office and learning facility under construction in Heber, Utah, near Park City, a larger state-of-the-art training facility coming to Tustin, California, and a fully redesigned website expected to launch within the next couple of months. Topics Covered Trade show tips: how to score free gear at the end of the last day Tony Gonzalez's personal life update First look at Fieldpiece's new analog manifold gauge set Refrigerant compatibility: R-22, R-32, R-454B, R-410A display on the new gauges The built-in pressure marker ring — a clever replacement for the wax pen trick Why every HVAC truck should have a set of analog gauges as a backup Use cases for analog gauges: dirty systems, long-term standing pressure tests, dead batteries Fieldpiece's two-pronged approach to the HVAC industry: reducing low-quality work and closing the skills gap The Fieldpiece School Partnership Program — resources, in-person support, student prizes, and lab tools Fieldpiece's 35-foot mobile training trailer: bringing live equipment to schools, contractors, and distributors The importance of hands-on, repetitive practice for trade skills — not just classroom learning Fieldpiece's new and expanded training facilities in Tustin, CA, and Heber, UT The revamped Fieldpiece Rewards Program — earning points for swag through product registration, events, and courses Fieldpiece University: free online courses with continuing education credit How small contractors can use Fieldpiece University to build internal apprenticeship programs A shoutout to the GRIT Foundation and their shared mission in workforce development Upcoming redesigned fieldpiece.com website Tony's trailer driving lessons — and a certain "learning opportunity" involving a sharp turn   Learn more about Fieldpiece's School Partnership Program at https://www.fieldpiece.com/schools/, Fieldpiece University at https://www.fieldpiece.com/fieldpiece-university/, and Fieldpiece's products at https://www.fieldpiece.com/  Have a question that you want us to answer on the podcast?

The residential HVAC industry is currently undergoing a federally mandated transition from R410A to more environmentally friendly A2L refrigerants. This shift is driving up equipment costs due to necessary hardware redesigns, factory retooling, and supply chain pressures. While homeowners can still service existing units, older systems nearing the end of their lifespan face higher risks of obsolescence and expensive repairs. Experts suggest that consumers should plan replacements proactively rather than waiting for a mid-summer system failure, which often leads to rushed, emotional, and overpriced purchasing decisions. By understanding these regulatory changes now, homeowners can avoid the inflated pricing and limited availability typically associated with emergency installations during peak seasons.This is a DEEP DIVE of Derek Cole's post on Refrigerant Changes: https://youtu.be/ir3psXFYnEI?si=m8BkGXCPXZQrCklg

The air conditioning and refrigeration industries are asking Congress to chill an EPA initiative started under the Biden administration to change refrigerants used in AC units. The EPA move seeks to respond to climate change by changing to refrigerants such as propane, which is highly flammable. To further complicate matters, there's a phase-in period with transitional coolants. We speak with Bob Cochell, owner of Gulf Coast Air Systems, former president of the Florida Refrigeration and Air Conditioning Contractors Association, and longtime advocate for the HVAC industry. 

In this insightful episode of the HVAC School podcast, host Bryan sits down with Jennifer Butsch, Director of Regulatory Affairs at Copeland, to discuss the rapidly evolving regulatory environment affecting the HVAC industry. With eight years of experience at Copeland and a background spanning codes, standards, and regulatory affairs, Jennifer provides a unique perspective on the challenges and opportunities facing contractors, technicians, and manufacturers in today's market. The conversation begins with an in-depth look at the EPA's Technology Transition Rule and the recent shift from R-410A to mildly flammable refrigerants like R-454B and R-32 as of January 1, 2025. Unlike previous refrigerant transitions that allowed for years of overlap, this transition was compressed into a much shorter timeframe due to building code requirements for the new mildly flammable refrigerants. While equipment delivery has gone relatively smoothly, the industry has faced significant challenges with refrigerant availability, particularly R-454B service gas. Jennifer discusses how OEMs have responded creatively, including pre-charging units with additional refrigerant and providing recovery cylinders as short-term solutions. The discussion also covers the ongoing debate about potentially returning to R-410A, which Jennifer argues wouldn't solve the current cost and availability challenges. She emphasizes that manufacturers have already invested heavily in transitioning their production lines and that rolling back would actually increase costs and timeline complications while moving in the wrong direction environmentally. The conversation touches on energy efficiency standards and the limitations of what can be changed under current legislation, noting that rolling back to pre-2023 efficiency levels would require Congressional action to revise the Energy Policy and Conservation Act. Jennifer and Bryan explore the complex world of tariffs and their impact on pricing stability, the potential defunding of Energy Star and what privatization might mean for the industry, and the challenges of regulatory fragmentation when federal oversight decreases and individual states create their own rules. The episode concludes with Jennifer's perspective on Copeland's philosophy of industry stewardship and practical advice for contractors on how to make their voices heard through trade associations and direct communication with legislators. Topics Covered: Technology Transition Rule - EPA refrigerant phase-down from R-410A to 454B and R-32 Refrigerant Availability Challenges - Current shortages in 454B service gas and industry solutions Mildly Flammable Refrigerants - Building code requirements and safety considerations R-410A Rollback Discussion - Why returning to previous refrigerants isn't a viable solution Energy Efficiency Standards - Legal limitations on rolling back efficiency requirements Tariff Impact - Effects on pricing stability and manufacturing decisions Energy Star Program - Potential defunding and privatization concerns Regulatory Fragmentation - Challenges when states create individual rules vs. federal standards Industry Stewardship - Copeland's approach to leadership and collaboration Contractor Advocacy - How to effectively engage with trade associations and legislators Manufacturing Investment Challenges - Impact of policy uncertainty on long-term planning Transition Timeline Management - Lessons learned and recommendations for future regulatory changes   Have a question that you want us to answer on the podcast?

In this short episode, Bryan clears up the confusion behind pumping vs. compression. Pumping is usually associated with liquid. Liquid, like vapor, is a fluid, but it's a lot denser and is essentially incompressible because the molecules are close together. Liquid volume varies based on temperature and density, but we can't squish the molecules together. That's why compressors with very little axial and radial compliance fail when flooded; they can't compress the liquid. A circulator pump in a hydronic system is an example of a pump that pushes liquid along, but the pressure difference across the pump is minimal compared to that of a compressor; the same is true of liquid vs. vapor CO2.  However, vapor molecules are far apart and can be squished together to take up a smaller volume. That's why vapor can go through compressors, which take a fluid of one volume and apply pressure to shrink it to a smaller volume, raising the temperature in the process. Pneumatics, as opposed to hydraulics, utilize compression to move vapor around in a circuit. Recovery machines need to be able to compress vapor refrigerant and pump liquid into the recovery tank. Compressors and pumps can either be positive displacement or non-positive displacement systems. A positive displacement system creates a trap and forces a fixed amount of fluid through a system, like a scroll compressor or a circulator pump. Refrigerant volumes may vary because vapor density varies with temperature and pressure (the volume flow is the same, but the mass flow varies). A condensing fan motor, on the other hand, is dynamic and varies the volume of air it moves in response to pressure, as the mechanism relies on velocity and kinetic energy to move air.   Have a question that you want us to answer on the podcast?

In this short podcast episode, Bryan talks about the CPS Molecular Transformator and what it does. The Molecular Transformator is a version of a tube-in-shell heat exchanger, which is a method of exchanging heat from one fluid medium to another fluid medium. Tubes containing a fluid pass through a shell containing water or glycol, and there is a heat exchange between that secondary fluid and the fluid being circulated in the tubes. In a Molecular Transformator, the fluid being circulated is recovered refrigerant, and the secondary fluid is water (in a bucket), which absorbs heat from the refrigerant and cools it down to make sure that the refrigerant enters the recovery tank as a liquid. Refrigerant recovery machines have condensers inside of them, but they are quite small and don't hold a lot of refrigerant by design; many recovery machines use microchannel coils. A lot of the time, the refrigerant leaving a recovery machine is a liquid-vapor mix and too high-temperature; a lot of people run a hose over the tank or put it in a bucket of ice. The "Molecular Transformator" tries to settle the vapor molecules down into a liquid; it transforms the vapor molecules using the same mechanism of a shell-in-tube heat exchanger. The main issue is that there will be leftover refrigerant in the Molecular Transformator after recovery. However, you can mitigate this problem with ball valves and proper purging. Do so responsibly to avoid venting refrigerant.   Have a question that you want us to answer on the podcast?
