Training has always been important in the heating sector, not least of all because of the dangers associated with working with gas, the traditionally dominant heating fuel in the UK. With the changes that are occurring across the heating industry, primarily the move towards decarbonization, manifesting in a transition to heat pumps, training is more important than ever. Principles of heat pump technology Training could take the form of a CPD on understanding the guides of heat pump technology That training could take the form of a CPD on understanding the principles of heat pump technology through to specific product training addressing installation, commissioning, and maintenance. Commercial heating training courses are abundant. Unless there is a specific manufacturer’s product you want to train on, how do you choose a training course and provider that is right for you? Here, we look at the key aspects to consider when selecting a training course and training provider. Expertise & knowledge By far the most important aspect of any training is the level of expertise and knowledge of the training providers. The training course needs to be both written and delivered by people who have direct experience in the heating industry. Knowledge or qualifications in training techniques and knowledge transfer are equally important. For contractor-based training, ideally, the trainers will have a background in heating engineering. This enables them to not only cover the core content of a training course but also address how it applies in real working-life situations. Knowledge or qualifications in training techniques and knowledge transfer are equally important. For specifiers looking to expand their knowledge through CPD courses, it’s helpful if these are presented by experienced Specification Managers who understand the needs of a specifier and have extensive knowledge of heating systems. On-site facilities The environment itself plays an important role in the success of the training The environment in which you learn plays an important role in the success (or otherwise) of the training itself, which is often overlooked. Being in a comfortable environment free from distractions will support you to better focus on your learning. Is the training held in a dedicated training center or a makeshift back office room? Is it a comfortable environment in terms of seating, desks, heating/air conditioning? Is the presentation equipment up to scratch? But most important of all, is the heating equipment you are learning about present, and is it functional? Training and Technology Centers  At our Training and Technology Centers, we provide learners with on-site access to a range of commercial heating equipment, including a unique thermodynamic heat pump simulator where they can view the change of state of refrigerant when in operation. Hands-on training for contractors is vital as it enables more learning by doing and problem solving, and therefore, greater depths of understanding can be gained. In our feedback survey, this comes up as one of the most important and popular aspects. It’s one thing to have something presented to you, but to be able to work through scenarios with expert support is quite another. Hands-on training for contractors is vital as it enables more learning by doing and problem-solving. Location A CIBSE-approved CPD, for example, doesn’t require hands-on training We’ve looked at the importance of how a training course is delivered, but where it is delivered also has a role to play. Does the training provider have training facilities nationwide, or in just one location? The latter could make for long travel times and even an overnight stay. Ideal Expert Academies are located around the UK at Hull, Leeds, Dalgety Bay, and Luton. Lastly, not all training needs to be done in person. A CIBSE-approved CPD, for example, doesn’t require hands-on training. In these instances, online training is a good, convenient option. Will the training provider be able to deliver this and how? Is it just a PowerPoint presentation, or are other elements included, such as video, attendee tasks, etc? Range of courses and delivery Having a range of courses is obviously important in that it provides you with choice and allows you to fill in the gaps of your knowledge, as well as learning about emerging technologies and best practices. A good training provider will also provide a flexible delivery model to meet individual learner needs and have the knowledge and expertise to support those with learning difficulties. Good training provider also provides a flexible delivery model to meet individual learner needs. Endorsement Ideal Heating’s adult learning provision was assessed by Ofsted, and they received an excellent report Whilst it’s important to do your own ‘homework’ on training providers, third-party endorsements are very useful. These come in different forms, from customer feedback (there are plenty of forums that provide you with the opportunity to ask for feedback), through to recognized industry awards, and independent assessment. Last year, Ideal Heating’s adult learning provision was assessed by Ofsted, and we received an excellent report, plus our Expert Academy team was recognized as Training Partner of 2024 by Hull City Council for delivering Skills Bootcamp programs for hundreds of learners in the area. We were also delighted to receive the inaugural BESA award for Training Provider of the Year 2024. Cost The last aspect I want to touch on when it comes to training is cost. How much should you pay for training? You should really consider the value you believe will be returned from the program and the provider you choose.  If you are going to benefit from state-of-the-art facilities, you may probably expect that experience may cost more than somewhere very simple and basic. Training providers are businesses, and the good ones do invest heavily in facilities and staff development. The good ones do invest heavily in facilities and staff development. Ideal Heating as a manufacturer strongly believe that our training services are part of what we deliver in our product sales. For this reason, we provide many of our training programs for free or at very low cost, despite the significant investment into our resources. Working alongside our specifiers and installers to meet their training needs builds for a strong relationship and successful projects. Choose wisely Taking time out from your busy schedule to dedicate to training is an investment, financially in some cases, so selecting your training course wisely to maximize that investment is sensible.

The HVAC/R industry is in the process of a major shift as A2L refrigerants become the standard in residential and commercial system HVAC. This change is being propelled by stricter environmental policy and advancements in refrigeration technology. However, the transition is not without its hurdles, posing new considerations for system owners, technicians, and equipment manufacturers. Favor of GWP alternatives The Environmental Protection Agency (EPA) has established clear guidelines to phase out hydrofluorocarbons (HFCs) in favor of lower global warming potential (GWP) alternatives.  The 700 GWP limit imposed by the EPA, forced manufacturers away from non-flammable A1 to mildly flammable A2L refrigerants for comfort cooling chillers and air-to-air unitary equipment. R-410A split systems  Under current regulations, R-410A split systems can still be installed until January 1, 2026 Under current regulations, R-410A split systems can still be installed until January 1, 2026, but manufacturers had to halt production of R-410A-based equipment by January 1, 2025.  As for packaged systems, which are fully assembled and sealed at the factory, sales will remain permitted until January 1, 2028, but only for equipment manufactured before 2025. Adaptation of A2L refrigerants These regulatory milestones mark a significant step toward a new era in HVAC/R technology, emphasizing sustainability and compliance with modern environmental standards. While the transition is underway in our market as we speak, there are some key factors that play into the adaptation of A2L refrigerants. How we implement, gain familiarity, and roll out these systems provides challenges.  System Design Modifications ASHRAE Standard 15 first added these requirements in its published version of 2019 ANSI/ASHRAE Standard 15 is widely recognized as the preeminent guide for the safe use of refrigeration equipment, as evidenced by its inclusion in building codes at the state and local level. ASHRAE Standard 15 first added these requirements in its published version of 2019. For high-probability systems, in which the basic design or the location of components is such that a leakage of refrigerant from a failed connection, seal, or component could enter the occupied space, these requirements underwent major revisions for the 2022 version, with intent to better harmonize with the requirements in UL 60335-2-40. Modifications in HVAC system design The transition to A2L refrigerants necessitates modifications in HVAC system design to ensure compatibility and safety. One significant consideration is component compatibility; all system components, including compressors, heat exchangers, and expansion devices, must be rated for A2L refrigerants to ensure optimal performance and safety.  Failure to use appropriate components could lead to operational inefficiencies or increased safety risks. Component Testing/Approval Requirements UL 60335-2-34 is a safety standard that applies to motor-compressors used in refrigeration systems UL 60335-2-34 is a safety standard that applies to motor-compressors used in refrigeration and air-conditioning systems. The UL 60335-2-34 6th edition was established in 2017 as the safety standard for compressors, introducing several key updates. One major change is the requirement for a new Maximum Rated Current marking, ensuring clear identification of electrical ratings. Additionally, the standard introduces various new testing methods for motors and their protective mechanisms to enhance safety and reliability.  Testing methods outlined in UL 207 UL207 covers “Refrigerant-Containing Components and Accessories, Nonelectrical” which are components Danfoss refers to as “line components”, such as filter driers, expansion valves and pressure regulating valves.  The testing methods outlined in UL 207 include burst pressure tests, fatigue tests, and hydrostatic tests to verify nonelectrical refrigerant-containing components and accessories. UL 207, which remains a referenced standard under UL 60335-2-40, has been reapproved for use with R-454B. Dealing with A2L refrigerants Compliance can be achieved through burst testing at five times the maximum pressure rating Unlike A1 refrigerants, where leaks at gaskets or mechanical seals were not a concern at twice the maximum pressure, such leaks now pose a significant issue when dealing with A2L refrigerants.  Compliance can be achieved through burst testing at five times the maximum pressure rating or by conducting a fatigue test at three times the maximum pressure rating without the product bursting or leaking from any mechanical connection. Implementation: Choosing a Solution Understanding what makes sense for your sector of the market for this transition is paramount in how OEMs will implement (and many already have) A2Ls into the next generation of equipment. Let’s zoom in and look at the HVAC segment related to commercial A/C units. The two main A2L refrigerants that were approved via SNAP rule 26, being used to replace R-410A in the 2025 transition requirement, are R-32 and R-454B. These two offer different approaches to the design requirements needed to be implemented. R-454B Danfoss has a selection tool called Cool Selector® 2 that is free to download online While no refrigerant is a direct replacement for R-410A, R-454B which has a GWP of 466, is considered a relatively close “drop in” solution. As such, most major components of the system, such as compressors and heat exchangers, can usually stay the same size. This is the lowest GWP solution available in the “high-pressure” range. With that being said, R-454B operates at lower pressures than R-410A, it also operates at lower mass flows than R-410A. This can leave your current liquid line, liquid line solenoid, expansion device slightly oversized. It is considered good practice to verify the sizing of these existing components when introducing R454B. Danfoss has a selection tool called Cool Selector® 2 that is free to download online. This can help you in verifying Danfoss components.  R-32 If the transition to A2L refrigerants is going to coincide with a major redesign of that unit, then R-32 (GWP 677) may be an option for your transition. R-32 will work at overall higher operating pressures and provide a significant increase in capacity vs R-410A. But with this comes the reality that most components in the system, possibly including piping sizes, will need to be changed to better suit the use of R32. R32 as a refrigerant, will also generate higher discharge temperatures than systems running with R-410A, creating a problem that manufacturers will need to account for in low ambient heat pumps and high condensing temperature environments. Leak Detection and Mitigation Refrigerant leak detectors must be installed in every unit with individual circuits charged with 4lbs As A2Ls pose a higher flammability risk, effective leak detection and mitigation strategies are essential for maintaining safety in environments where A2L refrigerants are used. Refrigerant leak detectors must be installed in every unit with individual circuits charged with 4lbs of A2L refrigerant or more.  More details on charge limits for systems and what mitigations requirements are needed can be found in UL60335-2-40 Annex GG. These detection systems enable quick identification and response to refrigerant leaks, reducing the potential for accidents or equipment damage. Danfoss leak detectors use thermal conductivity technology, were among the first to be UL-approved a year ago and come in a variety of configurations for HVAC/R equipment manufacturers. Proper mitigation strategies Proper mitigation strategies are crucial for preventing refrigerant accumulation in case of leaks. They must be tied into the unit control scheme. Disengaging any heating elements eliminates the possibility of ignition sources. Engaging evaporator fans increases circulation, ensuring that any leaked refrigerant is quickly dispersed, minimizing the likelihood of hazardous concentrations forming. In addition, per UL60335-2-40, service and maintenance procedures must incorporate regular leak inspections as a standard practice. Refer to ASHRAE 15 or UL60335-2-40 for further readings and requirements. Service and Familiarity Technicians must gain a version of the parts of A2L refrigerants and are required to pass an A2L test While manufacturers focus on design changes to accommodate the A2L transition, industry members who will install and service units also must adjust to the changing landscape of refrigerant. Technicians must gain an understanding of the characteristics of A2L refrigerants and are required to pass an A2L certification test under EPA Section 608.  Looking Forward This phase of transition is better conceptualized as a mid-term solution. The American Innovation and Manufacturing (AIM) Act was passed in 2020. This directed the EPA to address hydrofluorocarbons (HFCs) and phase down production and consumption of HFCs by 85% by 2036. It is likely in the future, we will see another step in transitions to ultra-low GWP Refrigerants such as R-290 (A3 class), R-1234ze, or R-515B. Before the AIM Act, individual states like California were looking to regulate their own refrigerant marketplaces. As adoption of new EPA regulations might be slowed under the current U.S. administration, it is uncertain if any future deregulation by the federal government could lead to some states restarting their own regulation programs. But as we stand now, lower GWP A2L refrigerants still continue to grow in the marketplace.

“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.

Certified technicians are less likely to make a mistake. Customers can have greater confidence in an installation's quality and reliability. Certification programs in the HVAC market Let’s take a look at several of the certification programs in the HVAC market. EPA 608 Certification is required by law for technicians to ensure the safe handling of refrigerants. Technicians are required to pass an EPA-approved test to earn Section 608 Technician Certification. Tests must be administered by an EPA-approved certifying organization. The U.S. Environmental Protection Agency (EPA) has a list of approved organizations on its website. Certification levels are Type I (small appliances), Type II (high-pressure appliances), Type III (low-pressure appliances), and universal (all levels) NATE Certification (North American Technician Excellence) ensures expertise in specific areas of HVACR systems, such as air conditioning, heat pumps, gas furnaces, etc. NATE is the largest non-profit certification organization for HVACR technicians in the United States and is considered the industry's gold standard. NATE certification proves that a technician has the knowledge and skills to properly install, maintain, and service HVACR systems. Technicians must pass a series of challenging exams, covering a range of topics, to become NATE-certified.

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."

The Olsen Group, based in Boca Raton, Florida, is a national pioneer in HVAC energy optimization. Donald Olsen and his seasoned team of HVAC control specialists have been in business for two decades, integrating energy-saving solutions into over a thousand commercial and large-scale residential projects. In the process, the Olsen Group has become one of North America’s top suppliers of Verdant thermostats. Verdant devices leverage intelligent occupancy sensors and proprietary software to reduce HVAC runtimes by 45 percent on average. HVAC control integration Verdant’s effectiveness, reliability, and broad compatibility have made Verdant the energy management solution of choice for thousands of hotels and MDUs, including multifamily buildings, senior living, and student housing.  The Olsen Group has forged a productive two-way partnership with Verdant. Donald Olsen and his team have made it a priority to share data, customer feedback, and requirements with Verdant – and Verdant, in turn, has come to rely on Olsen when they need to field test a new solution. In May of 2024, Verdant reached out to Olsen for help with a new pilot program aiming to facilitate more effective HVAC control integration, easier service, and deep energy savings for MDU projects around the globe. The Challenge Commercial VRF systems have an extremely attractive set of upsides for hotel operators Inverter (VRF) system design is becoming increasingly common in hospitality settings. Commercial VRF systems have an extremely attractive set of upsides for hotel operators. They are significantly more energy efficient and quieter than traditional VTACs or PTACs; they can provide simultaneous heating and cooling to different zones for optimal guest comfort; and they allow both individual room-level setpoint control and building-level centralized management. However, the majority of VRF units cannot connect directly to a third-party smart thermostat. Because they rely on proprietary manufacturer protocols for variable speed commands and internal diagnostics, VRF units require an external control solution to facilitate bidirectional communication with Verdant thermostats. Installation and commissioning process Every additional component in a system adds complexity and opportunity for human error. In hotels, that complexity is multiplied across hundreds of rooms. “HVAC systems are installed dark for new builds, with no power running to the site,” says Donald Olsen, President and Owner of the Olsen Group. “There’s no way to test as we go. If there are any mistakes during installation, we find out about it when the lights go on after project completion.” And mistakes are nearly inevitable. Some third-party controllers have prominent dipswitches that can be easily snagged or tripped during transportation or installation, altering their configuration and causing them to fail once the system is powered. These switches are often accidentally tripped multiple times throughout the installation and commissioning process, pioneering to a never-ending cycle of errors and service calls. VRF control solutions  Adding to the issue, not all third-party control keys have the ability to retrieve and solve system error codes “Once properly configured and installed, VRF control solutions tend to be incredibly reliable,” says Olsen. “Getting them there is a real challenge, however. Accidents, human error, and repeated recalibrations can drive serious project overruns and client dissatisfaction.” Adding to the problem, not all third-party control solutions have the capability to retrieve and translate system error codes. “If the central management system isn’t getting certified manufacturer control signals from the control device, it may no longer recognize the thermostat. The system will continue to function, but it will always show up in the central manager with an error message,” warns Olsen. Airzone Aidoo Pro control solution These false error reports degrade the overall utility of the central management system, robbing operators of the ability to detect and mitigate problems proactively and requiring onsite testing to diagnose any issues. As VRF systems become the norm for hospitality projects, Verdant needed a solution to reduce the possibility of accidental misconfiguration and improve visibility into system functionality. They called on Olsen to conduct a pilot program, retrofitting sixteen VRF units in the Jacksonville Beach, FL Springhill Suites with the Airzone Aidoo Pro control solution. The Solution For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller The Jacksonville Beach Springhill Suites is a 156-room hotel with a state-of-the-art Daikin VRV rooftop chiller system. The Airzone Aidoo Pro ships preconfigured for the specific HVAC unit model, reducing the possibility for errors during initial installation. For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller. This 1:1 system design simplifies operations and troubleshooting: Any issue can be immediately traced back to a single unit, minimizing the scope and duration or repair downtime. “The Airzone Aidoo Pro offered two key upgrades as a VRV control solution,” says Olsen. “First, the dipswitches are recessed, making them much harder to trip accidentally. Second, Aidoo makes the system much easier to service. We can read error codes, run tests, and diagnose issues remotely, without ever needing to disrupt a guest’s stay.” Airzone’s expansive library This advanced remote management is enabled by Airzone’s expansive library of manufacturer protocols. “Because of our close relationship with HVAC manufacturers, Aidoo Pro can provide the proprietary control signals the central management system is expecting to see,” says Borja Fernandez, Director of OEM Solutions, Airzone. “That preserves all the features of the HVAC unit and thermostat, while also eliminating persistent false error codes. With Aidoo Pro, the central management system can function as a single-pane-of-glass HVAC monitoring and control solution for the building, as intended.” Results and Next Steps The pilot program is expanding to new builds around the globe, including projects in the UK Olsen reports that Springhill Suites is happy with their upgraded VRV system. “They have more visibility into the system and fewer services calls,” says Olsen. “When there is an issue, we can diagnose it remotely for faster resolution and less guest room downtime. It’s a much better customer experience overall.” Verdant is encouraged as well. This pilot program is expanding to several new builds around the globe, including projects in Central America, the Caribbean, the UK, and the EU. HVAC energy savings “There is a massive untapped market for energy-efficient HVAC upgrades in the Caribbean region,” says Olsen. “Energy costs there can exceed a dollar per kilowatt hour. Cost-effective devices like Verdant thermostats and the Airzone Aidoo Pro pay for themselves very easily in that scenario.” Verdant and the Olsen Group have built global brands by helping commercial properties realize significant HVAC energy savings. Through the Airzone Aidoo Pro pilot program, they are continuing to innovate, enabling reliable integration and enterprise-grade control on highly efficient VRF units. “The demand for commercial VRF control is definitely there,” says Olsen. “With Verdant and Airzone, we can deliver it with ease.”
