Following First Minister John Swinney’s recent comments in The Scotsman describing hydrogen for heating as a “new prospect” and a “really exciting opportunity,” the Plumbing and Heating Federation cautions that hydrogen is “neither cost-effective nor efficient” for domestic heating. Instead, the Federation calls on policymakers to fast-track proven low-carbon options such as heat pumps, heat networks and comprehensive building upgrades. Efficient for domestic heating Scott Sanford, Technical and Skills Manager at the Federation said: “Extensive evidence shows that hydrogen is neither cost-effective nor efficient for domestic heating, and it remains largely untested in that context." "Even the Climate Change Committee suggests hydrogen’s role is primarily in industries where there are few or no alternatives, such as chemicals, cement and certain power-generation segments that rely on Carbon Capture and Storage." Speculative hydrogen heating schemes Sanford added: “That leaves little room for its use in heating our homes, especially given that producing green hydrogen typically requires more renewable energy than heat pumps. Instead of diverting resources into speculative hydrogen heating schemes, we should focus on proven, readily deployable options like heat pumps, heat networks, and building upgrades." “Homeowners, landlords and businesses need clarity and confidence about which technologies are truly safe, affordable, and effective as we transition to low-carbon heating.”

“If you don’t like the weather in New England, just wait a few minutes.” To this day, Mark Twain’s quote is used to describe quickly changing weather conditions in regions throughout the United States, United Kingdom, and elsewhere. However, in contrast to the weather, the climate change being experienced globally is creating nontraditional conditions that are much more permanent. Consequently, HVACR systems are being subjected to a new set of conditions that, if not addressed properly, may significantly impact performance, efficiency, and lifespan.  Report from Climate Central 75% of the Earth’s land has become permanently drier over the last three decades Consider a few examples. According to a recent report from Climate Central, as a result of climate change, Michigan has nine fewer subfreezing days in winter. The European Union’s Copernicus Climate Change Service reported that the average temperature in the summer of 2024 in Europe was 1.54 C above the average between 1991 and 2020.  According to the United Nations Convention to Combat Desertification, 75% of the Earth’s land has become permanently drier over the last three decades, caused in part by declining humidity in some regions. Climate change impacts such as these have made it increasingly important for HVACR contractors to understand the ways new weather-related factors can challenge equipment performance and durability—and to help customers optimize the resiliency of their systems. Three main challenges To follow are insights and tips that can help contractors successfully “weather” three main challenges driven by climate change: extreme heat, high or low humidity, and extreme weather events.  As this information demonstrates, no matter how hot, dry, wet, or stormy your region has become, being proactive in system checks and maintenance can help customers’ systems run effectively, minimize repair costs, and ensure equipment operates through its expected lifecycle.  Climate-change impact one: extreme heat In extreme heat, parts such as compressors and condensers undergo more than the standard wear From potential leaks to higher energy bills, the need for air conditioners to run longer and harder to achieve desired cooling temperatures as temperatures rise can be literally and figuratively costly to your customer, a building’s occupants, and the environment. In extreme heat, components such as compressors and condensers undergo more than the standard wear and tear. If not properly maintained to meet rigorous demands, equipment may not be able to cool a space adequately. This means it will potentially consume more energy and increase energy bills. Equipment could also overheat, break down, require costly repairs, and reach end of life more quickly. In addition, higher temperatures, longer run times, and increased condensing pressure may lead to more leaks. Take these steps to help HVACR system owners overcome the challenges of extreme heat: Check air filters frequently and replace them as needed. Dust and debris can accumulate quickly in hot, dry weather. Perform comprehensive regular maintenance. This should include cleaning condenser coils and maintaining proper refrigerant levels. Optimize settings. Raising the thermostat slightly when daily temperatures peak can help reduce energy consumption and wear and tear on components. Work with facility managers to ensure proper building insulation. This can reduce heat gain and lessen the burden on air conditioning systems. Create shade for outdoor units and keep them clear of debris. Protection from direct sunlight can help maintain cooler operating temperatures. Climate-change impact two: humidity Indoor comfort and HVACR system performance depend on keeping the right humidity balance Indoor comfort and HVACR system performance depend on maintaining the right humidity balance. When humidity is too low, air is dry and static, leading to discomfort for occupants and potential issues with air quality and system operation. However, if humidity is too high, systems will have to work harder to remove moisture from the air while simultaneously providing the desired level of cooling. Take these steps in high-humidity situations: Keep tabs on moisture buildup and perform regular cleaning of components such as ducts, filters, and evaporator coils. Identifying and removing moisture accumulation can prevent damage from mold or corrosion. Ensure proper insulation of ductwork to help mitigate moisture buildup. Enhance dehumidification systems and make sure they are properly sized to handle specific humidity levels. Check air filters, blowers, condensate drains, and ductwork to ensure proper airflow. In low-humidity situations: Install humidifiers. Consider humidifiers that can be integrated with the heating/cooling system to achieve a consistent level of approximately 30% to 50% relative humidity. Perform regular humidifier maintenance, including cleaning and replacing filters, checking for mineral deposits, and ensuring all lines are clear. Ensure proper insulation of ductwork and seal any leaks. Perform regular maintenance checks of HVACR systems as noted above Climate-change impact three: extreme weather events It’s not unusual for extreme weather events—including intense thunderstorms, snowstorms, and windstorms—to cause power outages and surges, flooding, or high winds, all of which can physically damage HVACR equipment. To avoid system problems or, possibly, total system failure it’s important to assess damage as quickly and thoroughly as possible then implement the necessary repairs or replacements. Be sure in these situations to always prioritize technician safety and, where applicable, to obtain clearance from emergency responders.  Take these steps to support system resilience during extreme weather events: Conduct routine maintenance as noted in factors one and two above. Work with facility managers to ensure buildings have proper insulation and weatherproofing. Have emergency backup power sources in place. Ensuring continual operation during power outages is especially important for mission-critical systems. Best practices for routine equipment checkups One final point to consider on this topic is that employing the practices above can help reduce further contributions to the global warming that drives climate change. One example is taking steps to prevent refrigerant leaks. Another is energy conservation that can be achieved by systems that run at optimized efficiency. Even efforts to prolong the lifespan of systems can help decrease the waste of resources and other materials.  While “waiting a few minutes” may prevent someone from unnecessarily canceling a ballgame or picnic on account of rain, the HVACR industry needs to address the challenges of climate change “without delay” and for the foreseeable future. Continuing best practices for routine equipment checkups and maintenance, increasing system checks in climates that have become hotter, drier, wetter, or stormier than usual; and employing some new techniques can all work together to ensure resilient systems, satisfied customers, and a healthier planet.

It’s often said the only constant in life is change. In the HVACR industry, that phrase has been especially true. We saw another year of transitions in 2024 that included evolving efficiency and refrigerant regulations, changing corporate net zero targets, the continued emergence of advanced heat pumps, and the impact of artificial intelligence (AI) in building management.  Smart and sustainable Throughout these transformations, the industry continues to overcome challenges and innovate as we transform the places where people live, work, and play into smarter, healthier, and more sustainable spaces.    As we look toward 2025, we can expect to see a continued, industrywide focus on decarbonization, heat pump development, A2L refrigerants, and AI as regulations expand and new technologies emerge.    Decarbonization  Decarbonization continues to be a very high priority for both the residential and commercial sectors Decarbonization continues to be a very high priority for both the residential and commercial sectors. This focus has transformed the way we design and install HVAC equipment and has created tremendous opportunities for those who invest in educating themselves on the evolving technologies, regulations, and incentives. Today’s building professionals and homeowners have an unprecedented number of incentives available at the federal, state, and utility levels encouraging decarbonization transitions.  Digital and net zero services For example, tax credits such as 25C for consumers and 179D for commercial building owners were expanded under the Inflation Reduction Act (IRA) and can significantly reduce the upfront costs of high-efficiency equipment, creating a compelling offer to replace less efficient systems. In commercial buildings, combining high-efficiency HVAC equipment like electric heat pumps with digital technologies and net zero services can help empower organizations to optimize their buildings and subsystems for both the short- and long-term. Heat pumps  Heat pump technology has advanced significantly in recent years, providing an electrified, high-efficiency HVAC option for nearly all applications – even those operating within colder climates. The Department of Energy’s (DOE) Residential Cold Climate Heat Pump (CCHP) Technology Challenge has propelled the successful introduction of heat pump prototypes that can withstand subfreezing weather. Similarly, the DOE’s Commercial Building Rooftop Heat Pump Accelerator program has helped drive packaged heat pump performance toward greater efficiency for commercial and light commercial buildings located in colder climate zones.  Water-to-water heat pumps Water-to-water heat pumps can replace legacy chiller and boiler combinations without the need for major changes Innovations in commercial water-to-water compound centrifugal heat pumps are also accelerating decarbonization within building retrofits. For facilities that require simultaneous heating and cooling, such as hospitals and universities, water-to-water heat pumps can replace legacy chiller and boiler combinations without the need for major changes to the existing HVAC infrastructure. This partial decarbonization approach can help building operators achieve their decarbonization goals while also lowering operational expenses (OpEx). In many instances, this reduction in OpEx also provides a path to funding additional decarbonization strategies.      A2L refrigerants   The EPA continues to make strides in reducing the consumption and production of hydrofluorocarbons (HFCs) under the American Innovation and Manufacturing (AIM) Act. As part of the AIM Act, the Technology Transitions Program will usher in sector-based regulations beginning January 1, 2025, prohibiting the manufacturing of equipment using refrigerants with a GWP higher than 700.  New protocols As a result, new equipment will continue to hit the market throughout 2025. In tandem, many contractors and technicians will begin working with A2L refrigerants for the first time. Because these refrigerants are classified by ASHRAE as mildly flammable, new protocols for safe refrigerant servicing, storage, and transportation, and refrigerant leak detection (RDS) requirements will be necessary for some applications.   ACCA A2L refrigerant training Contractors should complete ACCA A2L refrigerant training and EPA section 608 certification With these changes, it is important to become familiar with updated codes, including UL 60335-2-40, 3rd and 4th editions, ASHRAE 15 and 15.,2, and the AHRI Safe Refrigerant Transition Task Force (SRTTF), as well as local and state regulations. Contractors should also complete ACCA A2L refrigerant training and EPA section 608 certification. Additionally, new digital tools such as RDS calculators can help contractors navigate A2L leak detection requirements and mitigation strategies while in the field.    AI and controls   AI is positioned to continue to make a huge impact in HVAC. We’re seeing more service techs using generative AI and co-pilots for troubleshooting rather than paging through manuals. At the same time, AI technology can predict if connected HVAC units may have issues, making it possible for service techs to address potential issues in their earliest stages or prevent them from happening altogether. Both of these use cases can help technicians service equipment more quickly, efficiently, and accurately, which can increase equipment longevity and reliability while reducing downtime and total cost of ownership.   Building performance AI-powered building controls can provide a holistic view into contextualized, full-building performance More HVAC systems are being equipped with AI-enhanced controls and reporting. The capabilities these tools provide can give building owners greater opportunities to optimize building performance, improve occupant comfort and well-being, and more easily reach sustainability targets. From a building management perspective, AI-powered building controls can provide a holistic view into contextualized, full-building performance, occupant experience, and sustainability. Openness and flexibility As AI becomes more commonplace, AI-centric building standards, such as ASHRAE Guideline 36, will also continue to emerge that balance sustainability with occupant comfort, health, and safety.    As we move into 2025, we can expect to see another year of equipment innovations, technology advancements, and evolving regulations. As an industry, we continue to face change with openness and flexibility. And it’s this mindset that empowers us to meet, and exceed, expectations – now and in the year to come.

As environmental regulations become increasingly stringent, the HVAC/R industry is turning to sustainable refrigerants to minimize environmental impact. A3 refrigerants—flammable gases with low global warming potential (GWP)—are emerging as a preferred choice. However, their adoption introduces additional regulatory requirements. EPA regulations To address these challenges, the industry is leveraging innovative solutions like enhanced small-diameter copper tubes, which enable compliance with EPA guidelines while maintaining performance and safety standards. In this article, we’ll explore key EPA regulations for A3 refrigerants and how small-diameter copper tubes play a vital role in optimizing system performance, ensuring safety, and achieving regulatory compliance.  Understanding A3 Refrigerants A3 refrigerants help HVAC/R systems align with current and upcoming environmental regulations A3 refrigerants are characterized by their low GWP and flammability, making them a sustainable alternative to traditional high-GWP refrigerants. Common examples include propane (R-290) and isobutane (R-600a). By reducing greenhouse gas emissions, A3 refrigerants help HVAC/R systems align with current and upcoming environmental regulations. Their benefits go beyond regulatory compliance. energy efficiency A3 refrigerants improve energy efficiency, enabling systems to operate more effectively while consuming less energy. This dual advantage of sustainability and operational efficiency reduces both carbon footprints and operating costs. As global regulations continue to phase out high-GWP refrigerants, A3 options stand out as a viable solution that balances environmental responsibility with system performance. Their efficiency and compliance capabilities position A3 refrigerants as a key player in the future of HVAC/R system design.  Advantages of Small-Diameter Copper Tubes 1. Meeting EPA Charge Limits  Small-diameter copper tubes offer a significant advantage in adhering to EPA refrigerant charge limits. With their reduced internal volume, these tubes require less refrigerant to maintain optimal performance. This feature is particularly beneficial when working with A3 refrigerants, as the EPA enforces strict charge limits to mitigate flammability risks while upholding efficiency.  2. Boosting System Efficiency with Enhanced Heat Transfer  When enhanced with internal grooves, small-diameter copper tubes maximize surface area contact with refrigerants Copper’s exceptional thermal conductivity, even with smaller tube diameters, ensures effective heat transfer. When enhanced with internal grooves, small-diameter copper tubes maximize surface area contact with refrigerants, further increasing heat transfer efficiency. This improvement translates to lower energy consumption and reduced operating costs, all while delivering reliable cooling performance.  3. Durability, Safety, and Ease of Installation  Using small-diameter copper tubes reduces the refrigerant charge required within a system, enhancing safety. Copper’s lightweight and flexible properties, especially when annealed, simplify installation, particularly in compact systems with complex configurations. Its natural corrosion resistance also ensures durability and long-term reliability, minimizing maintenance needs over the equipment’s lifespan.  Innovating for a Sustainable Future  As the HVAC/R industry transitions to A3 refrigerants, adapting to stricter EPA regulations requires innovative system designs that address safety, efficiency, and performance challenges. Small-diameter copper tubes provide a practical solution by reducing refrigerant charges, enhancing heat transfer, and delivering reliable, durable performance.  reducing environmental impact These copper innovations are especially valuable for compact, high-performance systems that demand precision and compliance with environmental standards. By embracing these advancements, the HVAC/R industry can ensure systems are future-ready, capable of meeting evolving regulations while maintaining efficiency and safety. Small-diameter copper tubes are paving the way for a more sustainable HVAC/R landscape, helping businesses succeed in reducing their environmental impact while achieving regulatory compliance.

Hydronics systems rely on water, steam, or water solutions to distribute heating and cooling throughout a building. They are inherently more eco-friendly than conventional alternatives. First and foremost, using water as a temperature regulation method is a natural choice. There is no carbon footprint involved in its creation, and there is no inherent danger in exposure to water in the event of a system failure. Water is more efficient at carrying heating and cooling loads than other technologies. Other benefits include a wider range of maintenance flexibility and longer system life expectancy. overall efficiency of hydronics  “A misconception about hydronics is that it's more expensive compared to other HVAC systems,” says Jim Nolan, market development manager, Xylem. “While hydronic systems may require a larger upfront investment, lifecycle costs are significantly lower due to the overall efficiency of hydronics.” Flexibility in Cold and Warm Climates Hydronics offers a wider range of flexibility for components, operation, and maintenance Compared to other systems, hydronics offers a wider range of flexibility for components, operation, and maintenance. That flexibility also extends to extreme climate conditions, says Nolan. Hydronics perform reliably at very cold and very warm temperatures for improved occupant comfort and reduced energy costs. Additionally, hydronic systems draw on water’s natural thermal storage capabilities, which can substantially offset operating costs during peak demand periods. For over 100 years, Xylem’s Bell & Gossett has been at the forefront of hydronic systems as a manufacturer of pumps, valves, heat exchangers, and accessories — including steam and heat transfer — for plumbing and wastewater applications. Since 1916, the company has made a name for itself through products, industry-pioneering training at the Little Red Schoolhouse, comprehensive solutions, and application expertise, says Nolan. Products and sustainability efforts “Xylem is continuously innovating to advance and embed sustainability holistically into our solutions – from the materials we source, to making them more compact and cutting emissions, to high-efficiency motors,” adds Nolan. Advancing the efficacy and efficiency of their foundational products is what Bell & Gossett is known for, and more broadly, what Xylem is doing to embed “high impact” into all its products and sustainability efforts, says the company. Quantifiable Effect on Decarbonization Smart pump solutions like Xylem’s Hydrovar® X Smart Motor tout ultra-premium efficiency As the built environment increasingly weighs the effects of climate change and decarbonization, products must keep pace to demonstrate quantifiable impact on addressing these challenges. Smart pump solutions like Xylem’s Hydrovar® X Smart Motor tout ultra-premium efficiency, sustainably sourced materials, and compact design, delivering high impact in terms of intelligence and productivity. Built-in condition monitoring empowers customers to leverage data for additional pump protection and optimized performance. Equally essential is continued education and collaboration with industry partners to help commercial building owners navigate the challenges of achieving decarbonization and net-zero goals, says Nolan. That includes training opportunities at Bell & Gossett’s Little Red Schoolhouse to teach industry professionals about sustainable solutions, he adds. Ideal distribution system “Water is considered technology agnostic – no matter what type of technology exists today or in the future, modern hydronic systems can easily adapt to a variety of energy sources,” says Nolan. “As solar and geothermal grow, building owners and designers are recognizing that hydronics provide an ideal distribution system for these alternative technologies to perform.” Hydronic system efficiency is already well-documented in thousands of real-world applications, says Nolan. Hydronics reduces operating costs by using water as a heat transfer medium, which is more effective than air. Efficiency and cost savings are maximized when these systems are powered by renewable energy sources. Overcoming Obstacles to Equipment Reuse In some cases, though, existing HVAC equipment may be too outdated for reuse In some cases, existing HVAC equipment can be reused to achieve sustainable, carbon-neutral systems, says Nolan. Adaptive reuse projects involve repurposing an existing building for new use and reusing as much existing equipment as possible to save costs, conserve resources, and minimize construction-related disruptions. Upgrading existing hydronic systems with smart technology like advanced controls and smart motors can improve performance and efficiency, says Nolan. Another option is to incorporate high-efficiency components like heat pumps. In some cases, though, existing HVAC equipment may be too outdated for reuse. In others, existing building footprints may limit design options. To overcome this, a thorough assessment of current building conditions and performance can provide a better understanding of the original system design. Identify ways to reduce energy consumption Energy audits, building performance evaluations and environmental impact assessments provide valuable insights into an existing building’s energy consumption, resource usage and environmental footprint. The purpose of these tools is to identify ways to reduce energy consumption or operating costs by upgrading to more energy-efficient equipment or by building a better system. “There’s a whole industry built around energy audits—they’re typically conducted by industry professionals who have qualifications or certifications to ensure they have the knowledge and skills to perform thorough and accurate assessments,” says Nolan. Challenges to Deregulation and Achieving Net Zero Deregulation or the elimination of natural gas in existing buildings presents challenges. While hydronic equipment is essentially decarbonized because it runs on electricity, many utilities still rely on fossil fuels. Only when those providers switch to renewable energy and the grid infrastructure is expanded to deliver enough electricity will environmental impact be realized.  Although many areas are moving toward decarbonization and achieving net-zero energy, in regions where energy is cheap, there are few incentives to embrace renewable energy and building electrification. As HVAC equipment becomes more efficient and uses less energy, communities will realize the cost savings and gravitate toward better technology.

SNAP Rule 26 marks an important milestone in the transition from commercial refrigeration to new refrigerants. The rule lists refrigerant substitutes that provide a spectrum of technological solutions to meet required performance, global warming potential (GWP), safety, and environmental standards.  SNAP stands for Significant New Alternatives Policy, a program by the U.S. EPA (Environmental Protection Agency) under the Clean Air Act. In general, the program aims to evaluate and regulate substitutes for ozone-depleting substances, considering their overall risks to both human health and the environment. Impact of SNAP Rule 26 Final SNAP Rule 26, Protection of Stratospheric Ozone, lists acceptable substitutes in commercial and industrial refrigeration. SNAP Rule 26 will be effective July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register as of July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register “To date, the SNAP program has provided a very effective framework for evaluation and approval in support of innovation and the transition to new technology,” says Andrew Pansulla, Technical Service Engineer, The Chemours Company, a global chemistry company that provides a range of refrigerant products. We asked Pansulla to elaborate further on the impact of SNAP Rule 26 and what lies ahead. Q: How will the Rule’s finalization impact various commercial refrigeration sectors? Pansulla: The rule’s finalization will impact commercial refrigeration in several ways. Areas, where impact will likely be seen, include providing more acceptable refrigerant options, adherence to updated standards, new equipment design standards, and the exemption of propane from the venting prohibition for refrigerated food processing and dispensing equipment. These impacts could trigger changes in operational, manufacturing, and environmental compliance strategies in the commercial refrigeration sectors. SNAP Rule 26 will enable the adoption of the listed substitutes, including Chemours Opteon™ refrigerants, with global warming potential (GWP) lower than existing refrigerants. This rule does not require any changes to existing equipment and will impact only new equipment that uses the specific substances referenced in the SNAP rule. Q: What is the outlook for additional requirements for safe handling and use of alternative refrigerants? What specific safety standards are expected or appropriate? Pansulla: As part of the comparative risk framework used by the EPA to assess new alternatives, the EPA considers and implements use conditions that will ensure the safe use of products. These use conditions rely upon existing safety standards (e.g., UL and ASHRAE) which are available at the time the rule is finalized. In the case of SNAP Rule 26, many of the use conditions require adherence to UL 60335-2-89 and ASHRAE-15-2022. These standards are reviewed and updated periodically to maintain relevance with the products subject to the standards. Q: What are any limitations of the use of A2L refrigerants under SNAP Rule 26? Pansulla: There are two main categories of limitations under SNAP Rule 26. The first, as mentioned above, is the adherence to specific safety standards that apply to refrigerants that are designated as mildly flammable (A2L). The second is based on the GWP of the refrigerant. In the case of the A2L refrigerants subject to SNAP Rule 26, the EPA imposed conditions on the type of equipment and specific circumstances in which the substitute may be used. For example, the EPA is permitting the use of R-454A in supermarket systems, but only on the high side of a cascade system, or when the refrigerant charge capacity is less than 200 pounds. Q: Which new-generation A2L refrigerants are fit for which commercial refrigeration applications? Pansulla: Under SNAP Rule 26, the EPA deems R-1234yf, R-1234ze(E), R-454C, R-455A, R-457A, and R-516A as acceptable subject-to-use conditions for various commercial refrigeration applications. This selection is primarily driven by these refrigerants having GWPs under 150. However, certain applications necessitate refrigerants with higher GWPs due to unique performance characteristics. For example, R-454B and R-32 were listed for industrial process refrigeration with exiting fluid temperatures below minus 30 degree Celsius because these two specific refrigerants have lower boiling points than the other six less-than-150-GWP alternatives. However, it is critically important to consider the additional use conditions when designing equipment with refrigerants that have a GWP greater than 150. Q: So various equipment needs different refrigerants? Pansulla: The EPA purposefully lists several different refrigerants in each application to allow for equipment manufacturers to consider a variety of different factors that go into refrigerant selection, such as energy efficiency, capacity, normal boiling point, temperature glide, cost, safety, and use conditions. There is no one-size-fits-all solution for the entire commercial refrigeration industry. Q: How can commercial refrigeration businesses achieve a smooth transition to A2Ls? Pansulla: Keys to a smooth transition to A2Ls include understanding what refrigerants the EPA has approved as acceptable substitutes under the SNAP program, the sector-based GWP limits imposed by the Technology Transitions Program under the American Innovation and Manufacturing (AIM) Act, and which refrigerants provide the best combination of technical performance and environmental characteristics. Many resources are available to navigate the regulatory landscape and select the best low-GWP refrigerants to meet the needs of this industry. Working with companies like Chemours, who has nearly a century of refrigerant innovation and experience, is a great first step in the transition process. Q: What is the “staying power” of A2Ls — based on their chemistry, sustainability, and other attributes, combined with regulations such as SNAP Rule 26? Pansulla: The identification, selection, and development of new refrigerants that deliver required performance while meeting increasingly stringent environmental standards is a challenging process. With the identification of certain hydrofluoroolefin-based (HFO) refrigerants as an alternative to meet these criteria came a new safety classification. These HFO-based refrigerants are classified as A2Ls. While slightly more flammable than existing hydrofluorocarbon-base (HFC) refrigerants, HFOs are much less flammable than hydrocarbons, which are classified as A3 (two categories higher on the ASHRAE flammability spectrum). Moreover, such refrigerants offer an excellent alternative to substances with higher toxicity, such as R-717. The listing of A2L refrigerants in SNAP Rule 26 clearly indicates that such refrigerants can be used safely in commercial refrigeration as well as many other applications, which are subject to the SNAP Program, when adhering to the applicable safety standards.

Wren emphasizes transparency by providing regular updates on the impact of contributions, including data, photos, and stories. The platform aims to make climate action simple and effective, ensuring that every dollar contributes to meaningful environmental change.  About A-Gas  A‑Gas is a world pioneer in the supply and lifecycle management of refrigerants and associated products and services. Through the first-class recovery, reclamation, and repurposing processes, we capture refrigerants and fire protection gases for future re-use or safe destruction, preventing harmful release into the atmosphere. For over 30 years, A-Gas has supported clients and partners on their environmental journey by supplying lower global warming gases and actively increasing the circularity of the industries we serve, building a sustainable future.   Challenge  HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 The widespread use of refrigerants like HCFC-22 (R22) presents a significant environmental challenge. HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 (one molecule of R22 has a global warming impact 1,810 times that of one molecule of CO2). If not properly managed, its release would have a negative impact on the atmosphere. As these refrigerants reach the end of their lifecycle, there is an urgent need for effective solutions to prevent their emissions and minimize their environmental impact.   Solution  To address this challenge, A-Gas recovers refrigerants for reclamation or destruction at A-Gas facilities across the country. By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry through its on-site refrigerant recovery service (Rapid Recovery®), refrigerant buyback programs, and wholesale supplier reclaim program (Refri-Claim™). HCFC-22 destruction project The ACR methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017 Wren and A-Gas formed a partnership to provide Wren subscribers with the opportunity to fund an HCFC-22 destruction project through the generation of A-Gas carbon credits to ensure the gas does not escape into the atmosphere. While the ACR (formerly American Carbon Registry) methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017, few have completed such projects because the price of HCFC-22 is so high; it is more profitable for organizations to reclaim this product.  ACR’s methodology As such, this is one of the first HCFC-22 destruction projects utilizing ACR’s methodology. Approved by the International Civil Aviation Organization (ICAO) to provide carbon credits in its Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), ACR is highly regarded across the world.  Results  The partnership yielded multiple environmental benefits:   Emissions Avoided: The initiative successfully avoided the release of 16,000 tons of CO2-equivalent emissions by destroying HCFC-22. This substantial elimination of greenhouse gas emissions demonstrates the effectiveness of the program.   Subscriber Engagement: Wren provided its subscribers with detailed updates on the impact of their contributions. These updates included data on the quantities of HCFC-22 destroyed and the corresponding emissions reductions. This transparency helped build trust and encouraged ongoing participation in climate action.   Educational Impact: The collaboration raised awareness about the importance of proper lifecycle refrigerant management. Wren and A-Gas educated the public on lesser-known aspects of climate change mitigation by highlighting the environmental benefits of destroying high-GWP substances.   Conclusion  This partnership enabled an environmentally conscious solution for the used refrigerant By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry.  refrigerant destruction protocols and technology "We are excited to work with A-Gas to push forward the standard of refrigerant destruction protocols and technology," said Landon Brand, CEO, of Wren.

Shadow Industrial, the UK’s pioneering shortwave infrared heating specialist, recently helped St. Helen’s Chapel, in Colchester, Essex, specify and install a low-carbon heating system, keeping the congregation warm and costs down. Installing 14 of its powerful ceiling-hung and wall-mounted heaters and 16 controllers from scratch, the new system has given visitors a warm, comfortable and sustainable place to worship, whatever the weather. Futureproofing sensitively Reducing energy consumption and increasing its efficiency is a goal that touches on every part of UK business and industry, especially against the backdrop of the drive towards Net Zero 2050. It’s especially important for the UK’s Eastern Orthodox Church, which has over 250 properties nationwide. With strict and ambitious ESG commitments, futureproofing these assets in the face of tighter climate change regulation, whilst delivering their core function is a real challenge. It’s especially important for the UK’s Eastern Orthodox Church, which has over 250 properties nationwide Some of its sites are centuries old, and it can be difficult to upgrade facilities here. One particular area of concern is how to heat these large, high-ceilinged, and poorly insulated structures. Crucially, visitors need to be comfortable, but simultaneously ensure utility bills and waste are kept to a bare minimum. Warming-up the congregation It was an issue at the forefront of the church’s mind when they took over the lease of St Helen’s Chapel, Colchester, Essex in September 2020; especially as the 16th Century, Grade-II building had no existing HVAC system. The congregation bore the brunt of this unfortunate situation over three consecutive winters, where temperatures would sometimes plummet down to 1°C. It made the church a particularly uncomfortable place to worship.  Grade-II building had no existing HVAC system Initial use of oil-fired heaters proved futile, failing to provide the necessary levels of warmth and releasing a large amount of CO2. Next, industrial fan heaters were introduced, to little effect; noisy, they also proved a significant disruption to services. Following further research, they decided to trial shortwave infrared heating, approaching Shadow Industrial on the recommendation of their electrician, who had installed its solutions on previous projects. A heating revelation Shortwave infrared heating is one of the fastest-growing and most disruptive categories of heating Shortwave infrared heating is one of the fastest-growing and disruptive categories in the heating and ventilation sector. Simply, the technology works by emitting focused radiant heat through a precision-engineered smooth parabola reflector; it heats the person, not the air around them. Wall-mounted and directed downward at individuals, the energy creates a comfortable and instant warmth, mimicking the gentle heat of the sun. It’s fast becoming popular in historic ecclesiastical buildings as it’s easy to install, with limited impact on the structural fabric, in addition to its effective heating function and low energy consumption. It is also unaffected by changes in air movement, making it particularly efficacious in drafty settings such as those found in heritage sites, like St. Helen’s Chapel.  Unrivalled performance, at a reasonable price Installed in 2023, Shadow Industrial’s systems have significantly improved the comfort of congregants, allowing them to remove coats during services. The impact was particularly felt among older people and children, for whom extreme cold can have an adverse impact on health during extended services. The client was worried their tight budget would not be enough to fully equip the church’s interiors Initially, the client was worried their tight budget would not be enough to fully equip the church’s interiors with heaters. However, it proved far cheaper than traditional electric or gas central heating. The entire system and installation totaled £20,000. Putting this in context, they were initially quoted £100,000 for underfloor heating; this represents a massive 80% upfront saving, with greater performance–a no-brainer decision. The entire system and installation totaled £20,000. Shadow Industrial and its team Commenting on the project, Shadow Industrial’s founder, Steve Levy, says, “We are deeply committed to the preservation and longevity of heritage buildings. With a focus on comfort, we have successfully executed numerous heating projects with this in mind, of which St. Helen’s Chapel is the latest. It’s such an important local landmark and it was great to be able to provide a solution that benefits all those who work, volunteer, and pray here.” Father Mark Shillaker added, “Shadow Industrial’s infrared heating systems have had a transformative effect. Now visitors can worship in maximum comfort even on the chilliest winter mornings. In fact, since we’ve installed these heaters we’ve actually seen an uptick in service attendance. Many thanks to Shadow Industrial and its team for their expertise and ongoing support.” Church of England's Heat Decarbonization Plan Shadow Industrial’s electric heating systems, present a low-carbon, net-zero alternative ideal for heritage structures, churches, and culturally significant buildings. They even align with The Church of England's Heat Decarbonization Plan, offering compliance and sustainability in a non-intrusive way.

When a company is one of the largest beverage distributors in the U.S., it’s crucial to stay ahead of the curve on everything that drives customer satisfaction, corporate responsibility, and a strong bottom line. Hensley Beverage Company did exactly that when it collaborated with Chemours and American Refrigeration Supplies, Inc. (ARS) to implement a system utilizing a new-generation A2L refrigerant, Chemours Opteon™ XL20 (R-454C).  Completed in 2023, the installation paves the way for companies throughout the commercial refrigeration industry to embrace refrigerant technologies that are both cost-effective and environmentally sustainable. Situation  Hensley Beverage, a Phoenix-based beverage wholesaler, supports a customer base of more than 9,000 accounts and more than 2,500 individual products, operating out of six locations across Arizona, USA. Hensley remains committed to maintaining exceptional product integrity, upholding its business legacy The company recently completed an acquisition that expanded its distribution footprint into New Mexico, making it one of the nation's largest family-owned and operated beverage distributors. As it grows, Hensley remains committed to maintaining exceptional product integrity, upholding its multi-generational family business legacy, and supporting various environmental objectives.  Upgrading refrigeration systems These factors, coupled with the current regulatory landscape (notably, the phasedown of legacy hydrofluorocarbon (HFC) refrigerants), have put Hensley’s focus on ways to upgrade its refrigeration systems. For the past several years, Chemours, ARS, and Hensley have worked together to retrofit the distributor’s existing R-22 and R-404A systems to Opteon™ XP40 (R-449A), a hydrofluoroolefin (HFO) blend offering zero ozone depletion potential (ODP) and a significantly lower global warming potential (GWP) than legacy products. Phasedown of HFC refrigerants Hensley Beverage is proud to partner with Chemours, TBSI, and ARS to help develop innovative solutions" However, with the ongoing phasedown of HFC refrigerants under the U.S. EPA’s American Innovation and Manufacturing Act (AIM), the teams began weighing the benefits of an even bolder upgrade.  “Hensley Beverage is proud to partner with Chemours, TBSI, and ARS to help develop innovative solutions and responsible business practices that drive sustainability in our community," said Alex Dunn, SVP of Operations, Hensley Beverage. Partnership and collaboration Alex Dunn adds, "These groundbreaking results are a culmination of partnership and collaboration. It is refreshing to work with three organizations that are this passionate about developing pioneering products that will help shape a better future for the communities we serve.” Solution  A mildly flammable refrigerant with an ASHRAE A2L safety classification, Opteon™ XL20 is designed for use in new equipment Even as Chemours, ARS, and Hensley continued to employ retrofit solutions in some areas strategically, they explored options that would put the company in a stronger position for the long term. Chemours recommended bringing Opteon™ XL20 (R-454C) into Hensley’s refrigeration plan. A mildly flammable refrigerant with an ASHRAE A2L safety classification, Opteon™ XL20 is designed for use in new equipment, so Hensley identified an old R-22 system near the end of its life that was ideal for replacement by a new system using Opteon™.  Opteon™ XL20 Opteon™ XL20 has been used for several years in Europe and is expected to become the new norm in the U.S. by 2026, based on the current direction provided by the EPA. Leveraging its experience in Europe, the Chemours team of technical service and business development resources is prepared to support end users as they consider trial installations using A2L refrigerants.  Opteon™ XL20 - The future of sustainable low- and medium-temperature refrigeration: GWP of 148 (a 96% reduction versus R-404A).

(TBSI), the local HVAC service provider. As global HVACR technology pioneers helping customers achieve their sustainability, decarbonization, and regulatory compliance goals, Heatcraft and Copeland had the knowledge and experience of emerging A2L requirements and the capabilities to support the project. TBSI was selected as the contractor for installation and servicing. Time- and cost-efficient With the team assembled, Chemours took the head on the project, ensuring that the contractor, Hensley’s service personnel, and others involved were certified through the ESCO Institute’s A2L refrigerant training program, and answering any questions from the local authorities.  After safely recovering the R-22 for use in other Hensley systems, the team from TBSI started removing the existing Keg 6 equipment, hanging new evaporator coils, and running new refrigerant lines. Installation, evacuation, and charging procedures were very similar to the current refrigerants in use by industry, making for a time- and cost-efficient process. Climate technology Copeland has always been focused on not just setting the standard in climate solutions" “Copeland has always been focused on not just setting the standard in climate solutions with pioneering brands in compression, controls, software, and monitoring, but pioneering the evolution in this space. Our role in the system design and installation for Hensley was right in our wheelhouse," said Brian Schroeder, Engineering Manager, Refrigerants, Copeland. Brian Schroeder adds, "What we accomplished together demonstrates that by bringing together energy-efficient products,regulation-ready solutions, and expertise, we can revolutionize the next generation of climate technology for the better.” R-454C refrigerant “Our tools and gauges were already enabled for the R-454C refrigerant. The startup and charging of both systems went pretty smoothly," said Sergio Pelayo, Vice President of TBSI. Sergio Pelayo adds, "TBSI is proud to have participated in the project at Hensley and, by doing so, added to the variety of equipment we’ve worked on since founding our business in 1990. This was a great opportunity to grow our experience with A2Ls.” Copeland monitoring data  Copeland applied monitoring units to the systems that capture nearly two dozen data points every second To make sure the system performed as expected, Copeland applied monitoring units to the systems that capture nearly two dozen data points every second. The data has shown that the systems are running as designed. “We are thrilled with the results of the R-454C project with Hensley Beverage," said Bob Landi, Vice President and General Manager of Heatcraft Refrigeration Products. Bob Landi adds, "As we continue our journey toward new regulation compliance, this successful collaboration has been instrumental in leveraging Heatcraft’s new product design efforts, with A2L refrigerants being an important part of the mix. We are poised to head the industry and provide more customers like Hensley with cutting-edge solutions that drive their success.” Summary Influenced by upcoming regulatory changes and stronger organizational ESG commitments, the commercial refrigeration industry’s transition to lower GWP refrigerants is inevitable. Opteon™ refrigerants provide organizations with lower GWP options that can help extend the useful life of their systems, as well as new equipment options that enable decades of reliable operation. Moreover, these systems answer the consumer preference for businesses that utilize responsibly manufactured products and support a greener environment.  Hensley’s approach Hensley’s approach demonstrates an ideal way for companies to meet the needs of refrigerating their products while following the guidelines of the HFC phasedown. It’s important to assess where equipment is in its lifecycle and determine if it makes the most sense in terms of budget, performance needs, and corporate vision to 1) retrofit existing equipment for more efficient and sustainable operation or 2) replace it with A2L refrigerant technologies and products. 

When they are one of the largest beverage distributors in the U.S., it’s crucial to stay ahead of the curve on everything that drives customer satisfaction, corporate responsibility, and a strong bottom line. Hensley Beverage Company did exactly that when it collaborated with Chemours and American Refrigeration Supplies, Inc. (ARS) to implement a system utilizing a new-generation A2L refrigerant, Chemours Opteon™ XL20 (R-454C). Completed in 2023, the installation paves the way for companies throughout the commercial refrigeration industry to embrace refrigerant technologies that are both cost-effective and environmentally sustainable. Situation The company recently ended an acquisition that grew its distribution footprint into New Mexico Hensley Beverage, a Phoenix-based beverage wholesaler, supports a customer base of more than 9,000 accounts and more than 2,500 individual products, operating out of six locations across Arizona.  The company recently completed an acquisition that expanded its distribution footprint into New Mexico, making it one of the largest family-owned and operated beverage distributors in the nation. As it grows, Hensley remains committed to maintaining exceptional product integrity, upholding its multi-generational family business legacy, and supporting a variety of environmental objectives. These factors, coupled with the current regulatory landscape (notably, the phasedown of legacy hydrofluorocarbon (HFC) refrigerants), have put Hensley’s focus on ways to upgrade its refrigeration systems. Phasedown of HFC refrigerants For the past several years, Chemours, ARS, and Hensley have worked together to retrofit the distributor’s existing R-22 and R-404A systems to Opteon™ XP40 (R-449A), a hydrofluoroolefin (HFO) blend offering zero ozone depletion potential (ODP) and a significantly lower global warming potential (GWP) than legacy products. However, with the ongoing phasedown of HFC refrigerants under the U.S. EPA’s American Innovation and Manufacturing Act (AIM), the teams began weighing the benefits of an even bolder upgrade. “Hensley Beverage is proud to partner with Chemours, TBSI, and ARS to help develop innovative solutions and responsible business practices that drive sustainability in our community. These groundbreaking results are a culmination of partnership and collaboration. It is refreshing to work with three organizations that are this passionate about developing pioneering products that will help shape a better future for the communities we serve,” Alex Dunn SVP of Operations, Hensley Beverage.  Solution Chemours recommended bringing Opteon™ XL20 (R-454C) into Hensley’s refrigeration plan Even as Chemours, ARS, and Hensley continued to strategically employ retrofit solutions in some areas, they explored options that would put the company in a stronger position for the long term. Chemours recommended bringing Opteon™ XL20 (R-454C) into Hensley’s refrigeration plan. A mildly flammable refrigerant with an ASHRAE A2L safety classification, Opteon™ XL20 is designed for use in new equipment, so Hensley identified an old R-22 system near the end of its life that was ideal for replacement by a new system using Opteon™.  Opteon™ XL20 has been used for several years in Europe and is expected to become the new norm in the U.S. by 2026, based on the current direction provided by the EPA. Leveraging its experience in Europe, the Chemours team of technical service and business development resources is prepared to support end users as they consider trial installations using A2L refrigerants.
