Don’t worry; Air Docs Heating & Cooling has a complete guide to AC replacement to help users find out all about the steps users need to take next.  The step to replace the air conditioning system shouldn’t be taken lightly. several factors to consider Modern air conditioners boast larger sizes and quieter operations compared to their predecessors It’s a significant decision that hinges on several factors – the age of the equipment, the frequency and cost of repairs, the energy bills, and issues related to operational efficiency, noise levels, temperature inconsistency, and indoor air quality.  As modern air conditioners boast larger sizes and quieter operations compared to their predecessors, they often necessitate adjustments to their installation spots. This article will help users make informed decisions about replacing the air conditioning unit. Recognizing the Right Time for AC Replacement Recognizing the right time to replace the air conditioning system is essential for keeping the home comfortable and energy-efficient. Let’s go over some of the key signs that indicate it might be time to consider changing the air conditioner: Age and Malfunction of the AC If the air conditioning system is over 15 years old, its operational lifespan is likely coming to an end. Decreased performance, such as not cooling effectively or cooling unevenly, can indicate it’s time for a replacement.  If the air conditioner doesn’t respond well to the thermostat or if certain areas in the home are cooler than others, it might be a sign of issues with the thermostat or ductwork. Frequent Repairs and Rising Costs When deciding between repair and replacement, consider the long-term sustainability and costs Frequent repairs, unusual sounds, moisture around the unit, and rising energy bills are signs of potential problems with the air conditioning system.  When deciding between repair and replacement, consider the long-term sustainability and costs. When the cost of repairing and operating an old AC unit is greater than the cost of installing and operating a new AC over a multi-year period, it’s time to replace the old AC. Refrigerant Type  Post-2010, new equipment cannot be manufactured with R-22 refrigerant (Freon). R-410A (Puron) is the standard now. If the AC requires R-22 refrigerant, consider replacing it, as R-22 is being phased out and can be expensive to replace due to decreased production. Thanks to the above-listed factors, users can make an informed decision about when to replace the air conditioning unit, ensuring that the home remains comfortable and the energy bills stay manageable.  The Importance of Professional Installation Embarking on an air conditioner replacement journey can be a complex process, but having a professional team for the AC installation on the side is a cornerstone for ensuring the efficiency, safety, and longevity of the new system.  Here’s why opting for professional installation within the AC replacement is crucial: Expert Installation and System Calibration The installation process includes securely attaching ductwork to the air handler, brazing refrigerant lines Before the actual installation, certified technicians meticulously assess and modify essential components such as low and high-voltage wiring, refrigerant piping, electrical breakers, ductwork, and the condenser pad. The installation process includes securely attaching ductwork to the air handler, brazing refrigerant lines, reconnecting electricity, and ensuring the drain system is properly reattached. These steps demand a high level of precision only professional technicians can provide. A comprehensive startup assessment follows the installation. Technicians check refrigerant levels, airflow, supply air temperature, and drain function to guarantee the air conditioning system operates at peak efficiency from day one. Safety, Warranty, and Efficiency Professional installers are well-versed in local safety codes and regulations, significantly reducing the risk of electrical fires or other hazards. Their expertise ensures the AC installation adheres to all safety standards. Plenty of manufacturers prerequisite professional installation as a condition of the warranty they give users. This stipulation underscores the importance of having the AC unit installed by certified technicians to maintain its warranty. Proper installation also prevents air quality issues by ensuring ductwork is leak-free, keeping pollutants and allergens out of the living space. Long-term Benefits and Professional Accountability Correct installation techniques extend the system’s lifespan and prevent costly future repairs. This includes using the right mounting hardware and ensuring all electrical connections are secure. Hiring a professional team not only protects against installation errors but also ensures a faster installation process.  Incorporating professional AC installation into the air conditioning replacement project is a necessity for ensuring the new system functions efficiently, safely, and effectively for years to come.  Maintenance Tips for the New AC Maintaining the new air conditioning system is paramount to ensuring its efficiency and longevity Maintaining the new air conditioning system is paramount to ensuring its efficiency and longevity and keeping the home comfortable throughout the warmer months. A well-maintained AC unit also means fewer calls for AC repair. Regular Inspection and Cleaning Users should clean the AC filter every month. A clean filter improves air quality and enhances the efficiency of the air conditioning system, preventing it from working harder than necessary. Inspect and clean the evaporator and condenser coils at least once a year to maintain thermal efficiency. Dirt and debris can insulate coils, reducing their ability to absorb heat. Ensure the condensate drain is clear of blockages. A clogged drain can cause water leakage, affecting the system’s efficiency and potentially causing water damage. Preventative Measures For central AC systems, maintain a 24-inch clear space around the air compressor and condenser units. This ensures proper airflow and system performance.  Schedule a yearly cleaning and inspection with a licensed HVAC contractor before the cooling season starts. This service should include cleaning coils, adjusting and replacing fan belts, lubricating motors and bearings, and checking refrigerant levels and pressures. System Optimization Incorrect refrigerant levels can reduce the efficiency of the AC unit, increasing energy costs Ensure the outdoor condenser unit is level. An unlevel condenser can cause premature wear and reduce the efficiency of the air conditioning system. Have a professional check for proper refrigerant levels and leaks. Incorrect refrigerant levels can reduce the efficiency of the AC unit, increasing energy costs and the need for AC repair. Regularly vacuum and wipe down vent covers to remove dust and obstructions, ensuring proper airflow.  The Replacement Process Consulting with local HVAC technicians is the first crucial step when replacing the air conditioning unit. These professionals will help users weigh the pros and cons of repairing versus replacing the HVAC system. Here’s how the replacement process goes: Technicians will ensure all power sources to the old system are safely disconnected. Parts, such as the air handler, condenser, and any associated ductwork, are carefully removed. Old parts are disposed of responsibly, with recyclable materials being separated. The area is inspected for any issues affecting the new installation, such as space constraints or the need for ductwork modifications. The site is thoroughly cleaned to ensure a clean environment for the new system. The new air handler and condenser are placed in their respective locations, ensuring they’re level and secure. Electrical and refrigerant lines are connected, following strict safety and efficiency guidelines. Once installed, the system is tested for functionality, including airflow and refrigerant levels. Throughout this procedure, it’s essential to remember that choosing the right professionals for the AC installation is vital. Certified technicians not only ensure a seamless installation process but also uphold the warranty of the new air conditioning system.  Wrapping Up: AC Replacement Guide Through this detailed exploration of AC replacement, we’ve traversed the critical paths from recognizing the need for a new air conditioner to emphasizing the irreplaceable value of professional installation and concluding with essential maintenance strategies.  These integrated steps collectively form a blueprint for ensuring comfort and efficiency in the living spaces while addressing energy concerns and operational costs.

Each day we’re reading headlines about decarbonization ambitions for buildings while challenged with supporting day-to-day operational needs. Yet, we’re still tasked with delivering energy and cost reductions. Given the magnitude of energy consumption and the importance to occupant/tenant comfort, HVAC systems warrant significant attention. There are a lot of options with new equipment and controls to drive energy use down and enhance overall comfort that are very impactful, when budgets allow. However, there are budget friendly options that should be considered now. There are aftermarket products that restore lost performance efficiency, reduce loads on equipment and extend equipment life.  A challenge is knowing which products really work and what can be trusted. Refrigerant additives have been around for decades, solving several issues including improved thermal heat transfer, reduced frictional forces through enhanced lubrication, acid scavengers, water displacement, stop leaks, and the list goes on. Over forty years ago, some of the first refrigerant treatments were formulated, with varied results. The principal objective was twofold: enhance the heat transfer from the refrigerant to the heat exchanger coils and reduce friction on the compressor moving parts.  How to reduce compressor friction and keep it low Industry offered improvements to refrigerant oils, building on synthetic oil development HVAC systems include oil to lubricate the compressor mechanical moving parts with mineral oil being the old standard, used for decades. Older systems with R-22 refrigerant, as well as other types, use mineral oil.  This oil, made from naturally occurring crude petroleum oil, is prone to breakdown over time from wear and elevated temperatures. This means hermetically sealed compressors operating with the same oil as when originally built are running with greatly diminished friction protection. Friction protection longevity was greatly improved with the advent of synthetic oils, but even these oils can see diminished protection from wear and elevated temperatures. Industry offered improvements to refrigerant oils, building on synthetic oil development. Two additives commonly found in gear oils include active sulfur with phosphorus, noted as Extreme Pressure (EP) gear oils. This same approach found its way to HVAC systems, adding materials that offered greatly improved friction reduction. Some mistakes were made, such as using polytetrafluoroethylene (PTFE), best known as Teflon. Although PTFE has phenomenal lubricating properties, it is too large of a minimum particle size, creating havoc within expansion valves. Teflon also received scrutiny by researchers identifying adverse health effects. Today, there are several technologies promoting improved refrigerant lubricants, either as a direct replacement or as an additive to existing oils. How to restore lost HVAC performance efficiency The refrigerant oils that keep compressor moving parts running serves a second important role: acting as a seal to keep compressed refrigerant from escaping from the compressor and ending up in the oil sump. HVAC engineers allow and design for some oil to migrate through the refrigerant loop, the condenser and evaporator coils. More sophisticated equipment, such as chillers, have features to collect and return most of this oil. Simpler systems rely on the high velocity of the refrigerant to pull the oil through the coils and return it to the compressor. Inevitably, some oil remains as a film on the heat exchanger coils and slowly builds through the operational life of the equipment. The oil buildup continues to reduce the heat transfer efficiency between the refrigerant and the coil walls. There have been numerous formulations brought to the market with few detailed accounts of chemistry specifics An opportunity was born for creative individuals to invent formulations that would remove this efficiency robbing oil layer. Early design attempts sometimes led to more problems than the efficiency improvements were worth. Some chemistry mistakes included using solvents or other cleaning agents to aid in removing oil from heat exchanger tubing. This diminished the effectiveness of the refrigerant oil and led to shortened equipment lives. There have been numerous formulations brought to the market over the past four decades with few detailed accounts of chemistry specifics. There are few patents in addition to product website information that offer limited details in the public domain, making it hard to trust the suppliers. Today’s formulations offer greater opportunity for realized performance gains, especially given advances in material science. Nanomaterials have enabled several newer solutions to be developed. One such product employs graphene, which is known for its fantastic heat transfer and lubricating properties. Nanomaterials offer properties to enhance heat transfer, improve lubrication while negating concerns about excessive buildup within expansion valves. For example, graphene exists as a one atom thick nanomaterial. Perhaps the biggest challenge to the use of nanomaterials was how to keep the particles in suspension over the life of equipment, something that most specialty chemical houses hold as trade secrets.  Some products offered today boost refrigerant performance, stating altered boiling points. The performance is achieved by adding particulate that acts as nucleating sites. As material science continues to advance, we’ll see more products enter the market that also address changes in the choice of refrigerants and refrigerant oils. How to select the best additive for your needs Make sure the formulation is compatible with your specific equipment, refrigerant and refrigerant oil When considering additives to reduce energy consumption for your HVAC refrigerant systems, your contribution to decarbonization, do your own due diligence and require validated performance efficiency improvements.  Make sure the formulation is compatible with your specific equipment, refrigerant and refrigerant oil. Given that many sales agents won’t divulge their respective chemistry (or don’t know it) and most individuals responsible for HVAC equipment aren’t chemists, look for credentialed validations and testing. Ensure the products have been evaluated against ANSI standard compatibility tests and performance validated to ASHRAE or other accepted industry standards.  What the market thinks of refrigerant additives Over the first few decades since the creation of efficiency improving formulations for refrigerants and refrigerant oils, there has been mixed market adoption. The early days of failed attempts with oil degrading use of solvents or the use of expansion valve clogging solids, left a lingering perception of “snake oil”. Only those businesses that took the time to sort through the offerings to find the truly validated products found success in reducing their HVAC energy use and an added benefit of extending the life of their equipment. Today the market is better accepting of newer technologies, gaining distance to the old wild west days of unproven formulations.  Trust is being earned for those businesses that offer professionally validated products that stand behind them with warranties.

The American Innovation and Manufacturing (AIM) Act is among the environmental initiatives and regulations driving the phasedown in the use of hydrofluorocarbon (HFC) refrigerants in the HVAC industry. The AIM Act’s schedule seeks to phase down HFCs by 85% by 2036. The first significant reduction in consumption and production under the AIM Act began on Jan. 1, 2022, representing a 10% reduction from a baseline value. The next major step begins Jan. 1, 2024, with an additional 30% reduction, followed by another 30% reduction starting Jan. 1, 2029. adoption of retrofit or new systems This phasedown, rather than phaseout, approach should prevent any debilitating disruption to the industry; however, the adoption of retrofit or new systems sooner rather than later is key to a smooth transition. “We have a unique opportunity to impact worldwide change, one business, one community at a time by supporting our customers through the phasedown of HFCs,” says Brandon Marshall, Americas Marketing Manager, Stationary and Specialty Applications, The Chemours Company. next-generation products Chemours seeks to help the industry navigate the complex technology and regulatory landscape As the inventor of Freon and Opteon refrigerants, Chemours has been driving evolution in the HVACR industry for nearly a century, innovating next-generation products for diverse needs and applications.

Chemours’ Opteon portfolio helps customers define and implement the right solution through the phasedown. Many systems are still operating with R-22, although the supply is now limited to the reclaimed refrigerant. Due to dwindling supply, these users urgently need to retrofit their systems. The next phasedown under the AIM Act is coming quickly on Jan. 1, 2024.  Market price availability and impact For several years, Chemours has seen commitments from major OEMs to produce equipment operating with HFOs. Marshall says that continued HFC phasedowns, OEM adoption, and increased manufacturing of HFO refrigerants by companies like Chemours will impact market pricing and availability for HFOs and HFCs.  The industry can expect an exponential increase in retrofits and new installations of HFO-charged equipment. R-454B Chemours Opteon XL41 was the “big product” the company emphasized at the AHR Expo in February. The R-454B refrigerant is the new-generation solution paving the way for what lies ahead in the short- and long-term regulatory landscape. It is the lowest-GWP replacement for R-410A on the market offering a 78% reduction in GWP while providing value and peace of mind as the industry transitions away from HFCs, says Chemours. Opteon XL41 The more people we can introduce to Opteon XL41 and the stronger our collaborations, the greater the impact" Opteon XL41 has been selected by leading global OEMs, including Carrier, Johnson Controls, and Rheem, which have announced alignment with Chemours for the utilization of this product. “All of us realize that the more people we can introduce to Opteon XL41 and the stronger our collaborations, the greater the impact we can have in meeting environmental objectives,” says Marshall. commercial refrigeration sector The commercial refrigeration sector is quickly following air conditioning by embracing next-generation products such as Opteon XL10 (R-1234yf/ AR4 GWP 4), Opteon XL20 (R-454C/ AR4 GWP 148), and Opteon XL40 (R-454A/ AR4 GWP 239). “However, many businesses operating refrigeration systems need to walk before they run,” says Marshall. “Not everyone can immediately invest the money and/or time for new installations.” OEMs OEMs are supporting the transition by ensuring a healthy supply of retrofit equipment is available while keeping close tabs on the demand for new equipment charged with next-generation products. Several high-performance, efficient, and environmentally sound retrofit solutions exist utilizing HFO refrigerants such as Opteon XP10 (R-513A/ AR4 GWP 631) and XP40 (R-449A/ AR4 GWP 1397).  Leveraging resources  Ultimately, everyone must appreciate the value of A2Ls and be comfortable using them “By remaining data-driven, suppliers in the industry will be ready to meet changing demands and support the health of businesses and the planet,” says Marshall. Ultimately, everyone must appreciate the value of A2Ls and be comfortable using them. This requires ongoing education and training. There are many opportunities for this already out there, so technicians and the industry need to start or continue to leverage these resources, says Marshall.  webinars Chemours offers a variety of training to ensure the safe use of A2Ls and encourage adoption as soon as it is practical. This includes webinars with several industry partners and leaders, on-site training, online training brochures, videos, and customer support to ensure everyone is prepared for the transition. best practices Fortunately, the use of A2Ls does not amount to a situation of “back to square one” that requires technicians and installers to relearn everything while maintaining current skills to continue to service older systems. In reality, A2Ls such as Opteon XL41 (R-454B) feel very similar to working with R-410A. For R-454B systems, the installation and service procedures are similar to those of R-410A.  Moreover, the best practices that technicians have used for years remain applicable with A2Ls. These refrigerants are safe when handled properly, offer lower toxicity, and have been used effectively around the world to increase efficiency and reduce emissions, says Marshall. Environmentally responsible operations Environmentally responsible operations are a reality that will continue and escalate" “The world is locked into driving towards a more sustainable planet,” says Marshall. “Environmentally responsible operations are a reality that will continue and escalate." "This is driven not only by the regulatory landscape but also by corporate responsibility missions. The businesses that thrive will support these missions at every level of their operations.” sustainability  As the phasedown continues and receives more attention, consumers will join the conversation, driving everyone from contractors to facility managers to show support for environmental sustainability. Marshall says the installers and technicians need to be prepared to service these HFO-driven systems otherwise, that business will “walk out your door.” Regulatory compliance “Regulatory compliance may be the strongest motivator for change currently, but in our industry, every player must work to reduce the overall consumption of higher-GWP products,” says Marshall. “It is our responsibility to the communities we serve.” Chemours is a global chemistry company with leading positions in titanium technologies, thermal and specialized solutions, advanced performance materials, and chemical solutions, all working to create a better world through the power of our chemistry, according to the company.

Gradient seeks to bring the benefits of mini-split systems - variable speed drive, efficient operation, heat pump heating - to a wider audience, by simplifying the installation process. Gradient offers a design that is installed in a window, but it has more similarities to mini-split systems than to a window air conditioner. simple installation The system is designed for simple installation by a layman – it generally takes about 15 minutes. Using heat pump technology, Gradient has the efficiency and power of professionally installed products, with similar features, at a lower price point. Our product is installed through a window, but still allows users to open and close the window" “Historically, a mini-split has not been feasible for every situation,” said Vince Romanin, the Chief Executive Officer (CEO) of Gradient (formerly Treau), adding “They need to be professionally installed, which can be expensive.” He further stated, “They also are not an option for renters or buildings that are not retrofitted. Our product is installed through a window, but still allows users to open and close the window and get natural light.” Gradient unit featuring modular design The Gradient unit resembles a bench with two thick supports that hang over a windowsill. The modular design places the power and noise outside the window. It may look like an ultra-modern window unit, but it provides more than cooling. The system’s heat pump can be used all year round, as a heating system for homes in moderate climates (where the temperature is usually 46°F or higher), and to supplement a main heat source in colder climates. Focus on full building electrification Vince Romanin adds, “Our focus is on full building electrification. This product is an important stepping stone toward our long-term roadmap of cold climate heat pumps that enable the removal of fossil fuels in heating buildings.” Gradient seeks to address the environmental impact of current HVAC systems. Forty-eight percent of all energy consumption in American homes is a result of cooling and heating. HVAC is a major contributor to climate change, due to the refrigerants they use and their use of fossil fuels. As the climate changes, the need for heating and cooling systems increases, thereby creating a vicious cycle. Advanced heat pump technology Gradient breaks the cycle with products that allow you to be cool and comfortable without heating the planet" “Gradient breaks the cycle with products that allow you to be cool and comfortable without heating the planet, using heat pump technology and a climate-friendly refrigerant,” said Vince Romanin, adding “It is engineered to be easy-to-install and easy-to-use from anywhere, thanks to a mobile app.” “HVAC installers currently require extra time and equipment to install traditional mini-splits. The Gradient system is faster and cheaper because it is self-installed,” explains Vince Romanin, adding “The long-term impact of this additional option for consumers can help installers serve more customers in less time and at lower costs.” Heat pump/air conditioner using climate-friendly refrigerants HVAC, in general, is a major contributor to climate change, due to the refrigerants that they use and also contributed to their use of fossil fuels. Current heating and cooling systems release about 9 Gigatons tons of carbon dioxide equivalents each year, which is around 20% of all emissions and more than the entire transportation sector. Gradient offers a heat pump/air conditioner that uses climate-friendly refrigerants, thus reducing heating and cooling emissions by up to 75% today, and by 99% in the next few years. The system is also attractive and easy to use. Gradient expects the system to emit 75% less direct and indirect carbon emissions than today’s systems. This is based on using more environmentally friendly refrigerants, being more efficient, and displacing fossil fuel heating with electric heat pump heating. Fully decarbonized heating and cooling system Vince Romanin said, “Our end goal is a fully decarbonized heating and cooling system, which we expect to get to, by continuing to push for more environmentally friendly refrigerants, pushing our heating capability into colder climates, and building demand response into our system, so that it can work better with grid renewables.” High interest in the new product is testament to the power of sustainability as a marketing feature" “High interest in the new product is testament to the power of sustainability as a marketing feature,” comments Vince Romanin, adding “We believe that good business and carbon reduction are not mutually exclusive. In the long term, creating a better environment in which to live is the best way to create the best environment for doing business.” There are also uses in commercial and multi-unit housing applications. The company is already in conversation with several commercial customers, ranging from multi-unit housing, hotels, and schools among others. Large commercial buildings in New York City will be required to meet new energy efficiency and greenhouse gas emissions limits by 2024. Solution to mitigate Costs of changing building infrastructure Gradient offers a solution to mitigate the costs of changing major building infrastructure, to in order accommodate new HVAC systems. The system does not require an electrical upgrade or new ductwork, and installation does not damage the exterior of the building. Currently, Gradient is available for pre-order across the United States of America (USA), with deliveries beginning from July 1, 2022. The company envisions expanding to additional markets in the future.

The story of Bluon is the tale of how a chemical company blended a new refrigerant, and then later evolved into a large, brand-agnostic online community that helps technicians do their job. Currently, Bluon is on the verge of monetizing its platform, linking e-commerce into its vast wellspring of technical information to guide HVAC installers.  Tdx 20 refrigerant blend Bluon created and received EPA approval for its Tdx 20 refrigerant blend (R-458A) to replace R-22 and provide 20% greater efficiency. The new blend was well accepted in the market, but technicians were a roadblock, faced with a need to retrofit the new formulation into hundreds of thousands of units in the field. To address the problem, Bluon created a smartphone app providing retrofit instructions for each unit on how to make the transition. Adding features to the app XREF allows the identification of appropriate replacement parts that are compatible with a certain HVAC unit As more technicians started using the app, it took on a life of its own. In response, Bluon added new features and functionality to help technicians every day. Then Bluon acquired the XREF Publishing Company and incorporated the company’s replacement and cross-referenced part information into the platform. XREF allows the identification of appropriate replacement parts that are compatible with a certain HVAC unit. After the acquisition, Bluon incorporated XREF’s massive database of HVAC 300,000 Models including original parts lists directly into the hands of technicians on its installer app. Additionally, Bluon included the cross reference capability into its overall platform to benefit local distributors who will soon be able to use the valuable data when answering order requests coming into Bluon Member technicians on the installer app. BluonLive Recently, Bluon completed its Series B with $37 million in financing, which is enabling them to develop an e-commerce platform (BluonLive), the final link that makes the app even more valuable to HVAC installers. (The refrigerant business still provides $12-15 million in annual revenue.) “We are the only global platform that has gotten self-adopted at scale by technicians,” says Bluon CEO Peter Capuciati. The app currently has 104,000 members, roughly 30% of the 320,000 technicians in the United States, who had previously tended not to use mobile apps. Capuciati says Bluon built the app in a user-friendly, “likable” way, which explains the large audience of “sticky” users. It also provides a high level of technical support for the industry. Launch of the app The app will transform how technicians buy parts and equipment for a job site “We woke up one day and had this large community of HVAC technicians,” adds Capuciati. “So how do you monetize it without adding costs for the technician?” When the e-commerce platform launches in May or June 2022, the app will transform how technicians buy parts and equipment for a job site. Historically, technicians often didn’t know what they needed to buy until they visited a local distributor, which had the required information about which replacement parts are suitable, cross-reference by part number with the various alternatives. Now that information is part of the Bluon platform to benefit the HVAC technician in the field. Distributors Working on the app Distributors who join the Bluon Network get access to what Bluon is calling BluonLive – a portal allowing them receive order requests generated from technicians in the field using the Bluon app. BluonLive covers both “direct replacement” parts, typically the same part but white-labeled by another company; and “substantial replacements,” which may need a different wiring harness, be positioned differently, etc. Notes about how substantial replacements can be made compatible are included for the distributor to see. “We help the industry across the board,” says Capuciati. “The techs on our platform get more work done; they are more productive.” More efficient technicians can help offset the shortage of technicians in the U.S. market. Less training required Distributors with BluonLive will inform the technicians exactly what part he or she needs at what cost Each year, an estimated two technicians retire from the workforce for every recruit to the industry.  The app can also provide information to help guide less experienced technicians and lessen the need for training.  Now the process of choosing the right part can be a true e-commerce experience. Distributors with BluonLive will inform the technicians with the Bluon mobile app exactly what part he or she needs at what cost. They can buy the part on the app directly from their local distributor. Convenience The local distributor still gets the business, and the technician gets the added convenience. The app can also help wholesalers, who have a shortage of counter staff and face the imminent retirement of many employees who have the most instinct and product knowledge. The expression is that “behind every great tech is great counter staffs.” Bluon effectively scales this expression and allows the required institutional knowledge to flow to any technician’s fingertips. Brick-and-mortar distribution Bluon expects to launch their e-commerce platform this June,  with up to 2,000 stores of the roughly 6,000 brick-and-mortar distribution facilities in the United States initially signed up. In this way, they will enable and enhance the supply chain at the local level, connect techs to local distributors, and keep the local wholesaler central to the HVAC industry. And to monetize the app, Bluon will collect a small fee from the distributor for each transaction that happens between the local technician using the app and the local distributor.

Wren is a climate subscription service that helps individuals offset their carbon footprint through monthly contributions. Users can calculate their carbon emissions using Wren’s intuitive calculator and fund various climate projects, including refrigerant destruction. 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. Landon Brand adds, "This is one of the most reliable and impactful project types we have found in our years of funding climate solutions, and we hope our community can keep blazing a trail to eliminate these dangerous refrigerants."

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). Zero ODP. Enables much higher charge sizes than highly flammable A3 refrigerants. Is a close performance match to R-22 and R-404A. Offers the optimum balance of performance and environmental sustainability. Provides an easy, cost-effective alternative to legacy refrigerants and new equipment applications. Utilizes well-known technology for ease of service and maintenance. performance, efficiency, and sustainability “Hensley was an early adopter of Opteon™ XP40, retrofitting equipment to experience better environmental outcomes, as well as high performance in low- and medium-temperature applications. Experiencing these benefits of HFOs whet their appetite to ask, ‘What next?’," said Joe Martinko, President of Thermal and Specialized Solutions, Chemours. Joe Martinko adds, "With a strong dedication to supporting their communities and the environment, while operating an efficient and thriving business, Hensley is a company that pushes the envelope. Chemours was ready with our next-generationOpteon™ XL20, which will ensure they achieve maximum performance, operating efficiency, and sustainability." servicing and Installation Heatcraft and Copeland had the knowledge and experience of emerging A2L requirements The installation brought together additional resources from the HVACR industry, including Copeland and Heatcraft Refrigeration Products, two ARS manufacturing partners as well as Technical Building Services, Inc. (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.
