ow that we’re all rested and looking forward to the 2025 AHR Expo (in Orlando, thank you, AHR), I’ll share some post-show ruminations. Watch for an extended review in our March issue. Our 12-person sales/editorial team from three magazines—CB, CONTRACTOR and HPAC Engineering—arrived in Chicago at various times on Sunday afternoon, and before long were making the rounds at a press tour and a half-dozen brand welcome events. The press tour was sponsored by Armstrong Fluid Technology. It was a tour of the $140 million renovation of landmark Cook County Hospital in Chicago’s West Loop. Steve Spaulding, editorin-chief of CONTRACTOR and Rob McManamy, editor-in-chief of HPAC Engineering, covered the tour. As evening fell, Copeland, Danfoss, JAGA North America, Heatcraft Refrigeration Products, Triangle Tube and US Boiler served to move our team in diverse directions. The Triangle Tube party was held at Siena Tavern in downtown Chicago, and included the broadcast of the NFL playoff game between the Lions and Bucaneers. JAGA North America Climate Systems welcomed 250 guests to the five-story Chicago Starbucks Roastery. The Roastery uses JAGA North America’s ‘Knockonwood Freestanding’ radiators to provide heat via low-H2O technology with super conductive, ultra-fast heat exchanger. US Boiler offered guests a fantastic view of the lights of Chicago from atop the top floor of the Wit Hotel. Hundreds of Danfoss guests rocked the night away at another packed Danfoss welcome event at the House of Blues, Danfoss’s favorite venue for its annual AHR bash. My first stop was Chicago’s Soldier Field, for two events, by Heatcraft Refrigeration Products and Copeland. The Heatcraft party was help in an upper level suite, and was just the right space for the approximate 100 guests on hand. The Chiefs. Bills playoff game provided background, as guests talked and gazed on the now silent playing field, now awaiting a great NFL draft. The Heatcraft team was very welcoming. Kevin Norris greeted arriving guests. while Michael Pennington, Andy Lin, David Bolanos and other HRP managers mingled with guests. A nice surprise for me was getting to see the team from REMCO, the Contracting Business

2012 Commercial Refrigeration Contractor of the Year. REMCO president Jai Hoover shared that the company has grown from 400 employees in 2012 to 800 today, all through organic growth, not acquisitions. The Copeland event was held on the lower level of Sodler Field, in the main indoor fan viewing area, with a huge TV screen and lots of good food. Many guests left at the end of the night with a gift from the annual Copeland raffle. Next, I attended the HVAC Tactical social media awards. Categories include podcasting, mentoring and amazing projects. One of our CB Influencers—Tersh Blissett—and his co-host Joshua Crouch took home the award for Podcasters of the Year. The HVAC Tactical mission is to support the HVAC techs at-large, through podcasts and video that cover projects and best practices to advance the trade. Monday began our three days of visiting a variety of brands, to view new and existing products. Watch for my full report in the March CB. Educational sessions are as important as visiting exhibits. Our reporter Kelly L. Falloon did an admirable job of covering a dozen sessions. Industry leaders discussed heat pumps, artificial intelligence (AI), refrigerants, and technician recruitment during a panel discussion Jan. 23 at the 2024 AHR Expo in Chicago: Ginger Scoggins, president of ASHRAE; Talbot Gee, CEO of HARDI; Steve Yurek, president of AHRI; Dominick Guarino, CEO, National Comfort Institute; Gregg Walker, CEO of ASHB; and moderator Bryan Orr, founder/ president of HVAC School and Kalos Services. The search for new HVACR talent was the topic of a panel discussion between Alison Neuman, North American workforce development program manager at Johnson Controls; Bryan Feilen, senior corporate account manager, Lincoln Tech; Scott Shaw, president and CEO of Lincoln Tech; Jose De La Portilla, senior manager of education and training, Rheem Mfg.; Byran Orr, founder/CEO of HVAC School and Kalos Services; and moderator Dominick Guarino, president and CEO of the National Comfort Institute. Find three of Kelly’s educational session reports on page 9 of this issue, and her other session reports at ContractingBusiness.com. And please seek out our show galleries. If you attended 2024 AHR EXPO, I hope you found what you wanted. Continued best wishes for a fantastice 2024!

penalty amounts based on cost-of-living adjustments for 2024. In 2015, Congress passed the Federal Civil Penalties Inflation Adjustment Act Improvements Act to advance the effectiveness of civil monetary penalties and to maintain their deterrent effect. Under the Act, agencies are required to publish “catch-up” rules that adjust the level of civil monetary penalties and make subsequent annual adjustments for inflation no later than January 15 of each year. This year, January 15 falls on a federal holiday. Therefore, new OSHA penalty amounts will become effective Jan. 16, 2024. OSHA’s maximum penalties for serious and other-than-serious violations will increase from $15,625 per violation to $16,131 per violation. The maximum penalty for willful or repeated violations will increase from $156,259 per violation to $161,323 per violation. Visit the OSHA Penalties page and read the final rule for more information.

plumbing and HVAC contractors in the United States and Canada. Pugh received the winning Scratch & Win Card after purchasing a Noritz NRCR Residential Condensing Tankless Water from wholesaler-distributor Hirsch Pipe & Supply at its branch operation in Santa Clarita, CA. Tyler Pugh owns All Coast Plumbing, a Southern California company that does residential and commercial work. Coming from a long line of plumbers, Tyler decided to obtain his license in 2017 before opening his company in the same year. His company principally serves the San Fernando Valley and its surrounding areas. Prior to becoming a licensed plumber, Tyler had over 20 years of experience working as a tankless water heating installer.

While he recommends many Noritz products to his clients, his favorite model is the NRCR111, which coincidentally was the winning product. “The NRCR is a favorite because of the size,” he explained. “I do a lot of remodeling and addition work. If I’m working on a project where the homeowner wants to add a bathroom, I know the Noritz models can handle the additional volume well,” Pugh said. The promotion, which began on June 1, 2023, included select models in the Noritz EZ and NRCR tankless series available at supply houses across the United States. Professional plumbing and HVAC contractors were rewarded with a free Scratch & Win Card and two opportunities to win prizes.

Guidance for Contractors at 2024 AHR EXPO Educational Sessions by Kelly L. Falloon

Contractors and AI at AHR EXPO Artificial intelligence (AI) has been in the news a lot in the past year, and some are wary of this technology. However, for home services contractors, AI can help with the office processes no one likes to do, such as answering after-hours calls, outbound dialing, and helping with overflow. “AI is not to replace staff but to enhance them,” said Joshua Crouch, co-host of Skilled Trade Syndicate’s Service Business Mastery podcast, told 2024 AHR Expo attendees Jan. 22 in Chicago. Crouch and his podcast co-host (and founder) Tersh Blissett have used many AI apps and software and believe AI can help contractors be more productive. Blissett—who owns two Georgiabased HVAC contracting businesses—noted that AI can produce robust reports on service call management, monitor equipment remotely, and analyze data. However, he added, to be aware of what information you are sharing in the AI space. Thoroughly review the vendor’s privacy policy, and examine your company’s cybersecurity systems to ensure you are protected. Blissett said to always review all AI-written content; this is especially true when having AI respond to negative reviews. Both stressed that contractors should start learning about AI and how it can be used in their businesses: it is not a fad and it is not going away. Joshua Crouch and Tersh Blissett were named the HVAC Tactical “Podcasters of the Year” at a special event.

Use IAQ to Lead in Your Market During the COVID-19 pandemic, people became more aware of internal air quality (IAQ) and how it can affect their health. Today, there is still a “heightened awareness” of IAQ’s importance in the health and safety of families and communities, noted Scott Tinder, training and instructional designer at Business Development Resources, before 2024 AHR Expo attendees. “People are actively asking for IAQ, especially post-COVID,” he said. “Today, wholesale distributors have about 100 SKUs of IAQ products.” To become an IAQ leader in your market, you need to be proactive: “In HVAC today, you have to be a pioneer.”

His presentation, “Three Ways You Can Use IAQ Products to Become the Leader in Your Market,” discussed: • Improve company profitability by offering IAQ on every sales and service call, with a goal of selling one IAQ product per day (to start). • Leverage your existing revenue producers (technicians) for these additional sales. • Enhance recruiting and retention by rewarding IAQ success. Tinder added that you must get buy-in from techs; and install IAQ products in their homes so they can see for themselves how the technology works. For consumers, ensure you have an easy process and financing options. “If you don’t, they’ll buy from Amazon, Home Depot, or Lowe’s,” he said.

The Role of Reputation in Home Service When looking at two similar HVAC companies, “the better reputation always wins,” explained Ryan Redding, CEO and founder of Levergy. He and Heather Ripley, CEO and founder of Ripley PR, discussed how contractors can build trust with their customers through reputation through public relations, speaking Jan. 22 to 2024 AHR Expo attendees. “Trust and credibility are not ego things,” Ripley said. “This especially comes into play during a crisis: Don’t ignore the media and tell the truth; otherwise, you’ll lose the trust and loyalty of your customers, negatively impacting your company.” She encourages contractors to have a crisis plan and media policy and make sure all employees are aware of them; media entities should refer to the company spokesperson for any comment. Redding noted about company reputation: • Do not use review gating, where only good reviews appear on review sites; people will be wary of companies with only good reviews. Plus, it’s just wrong. “Encourage customers to leave negative and positive reviews,” he said. • Don’t hire anyone to control your social media program— even if they’re young. Your social media team should be experienced in boosting company reputations. • Ensure your CSRs and techs “anchor” your reputation by constantly repeating your expert service mantra to customers from the first call to the finished service. Then, ask for the review.

Dr. Chuck’s Corner: Resolve to Take Steps for a Smooth Refrigerant Transition The industry rang in the new year by starting an additional 30% reduction in hydrofluorocarbon Dr. Charles (HFC) production “Chuck” Allgood and consumption is Refrigerants Technology Leader under the U.S. EPA’s for Chemours. American Innovation and Manufacturing (AIM) Act. HFC phasedowns have reached the point where members of the industry can no longer be “thinking about” how they will adapt. It’s important to engage in activities that can help ensure your business transitions smoothly—as well as optimizes opportunities from new-generation hydrofluoroolefins (HFOs) and emerging A2L refrigerants. Here are five steps contractors should start now and continue throughout the year. 1. Implement a refrigerant management plan. Production and consumption phasedowns mean less and less HFC supply will be available for servicing existing equipment. Consistently following a process of refrigerant recovery, recycling, and reclamation is extremely important for ensuring there is enough refrigerant to meet the needs of your customers and the industry. When servicing equipment or taking it out of use, recover every possible bit of refrigerant, then recycle it for reuse

or send it to a certified reclaimer to be reprocessed and reintroduced into the supply stream. 2. Learn about A2Ls. As the world confronts climate challenges more aggressively than ever, adoption of A2L refrigerants in North and South America is accelerating. Already widely available in Europe and Japan, A2Ls are expected to see broad adoption in the U.S. through 2024, as more states amend building codes and standards. Understanding the ins and outs of A2Ls—including their benefits over legacy refrigerants, differences in how they are used, safety considerations, and what OEMs are adopting them—allows you to properly guide your technicians and customers, while developing a business strategy to introduce A2Ls into your equipment and service offerings. 3. Engage trainers—for you and your technicians. Whether we’re talking about mildly flammable A2Ls or other HFOs or HFCs, staying current and keeping your technicians trained is highly important. Training is a top priority for ensuring safe handling, optimal equipment performance, and quality work that supports the integrity of our industry. In fact, there is the potential for authorities to make it mandatory. Regardless if training is voluntary or mandatory, contractors should call on companies such as Chemours that offer

programs that train “the trainer” and the technicians. 4. Stick with your trusted supplier. The more that HFCs are phased down, the greater the incentive will be for them to enter regions illegally. In addition to thwarting environmental goals, illegal refrigerants typically have poor quality that makes them unsafe and inefficient for use. The best way to protect your crew, customers, and business is to continue to use your trusted supplier and avoid being lured in by “too good to be true” prices. 5. Be prepared to communicate with your customers. When it comes time to have the “repair, retrofit, or replace” conversation with a customer, make sure you’re prepared to do it in a way that enables them to make an informed decision that is best for their home or business. Educate yourself on all the refrigerant options available today, so you can point out advantages of one over another. These should include energy savings, environmental benefits, and performance attributes, plus the cost of new equipment, retrofits, or continual repairs. The AIM Act phasedowns have been structured to support a workable, reasonable transition. Achieving that requires everyone in the industry to do their part. These five steps will support your business, customers, and the planet.

Fieldpiece Instruments has introduced three valve core removal tools (VCRTs) designed to improve system charging, recovery and evacuation tasks. VCRTs remove the valve core from service valves in air conditioning, heat pump, and refrigeration systems to replace defective cores and provide an unobstructed flow of refrigerant for faster servicing. The Fieldpiece VCRTs represent a significant leap forward in valve core removal technology, overcoming the limitations of existing tools. One of the game-changing features within the Fieldpiece VCRT lineup includes an integrated sight glass that allows technicians to verify at a glance that the valve core is captured prior to removing it and confirm when refrigerant is flowing. Fieldpiece eliminated the frustration that techs face when it takes multiple tries, and lost refrigerant, before the valve core is captured with current competitive products. The Fieldpiece VCRT capture tip also includes an interior gasket that the valve core pin presses into to secure it for removal. No more fishing around for lost valve cores—a solid grip guarantees that the job is done right the first time, every time. Another Fieldpiece exclusive feature is a comfort spinner, a free-spinning, rubberized cap that makes removing and inserting the valve core, while under pressure, easier and more comfortable. Like the sight glass, this comfort spinner is available on the VC1G and VC2G models. All three VCRT models, including the ultra-compact VC1, include a magnet in the cap to keep the removed valve core on hand during service. All VCRT models are equipped with a 1/4-in. service port fitting that can be swapped in the field with an optional 5/16” service port fitting for mini-split systems, conveniently reducing the number of tools to carry. Replacement capture rod assemblies also streamline the maintenance process. Techs can say goodbye to deep-buried O-rings, as these simple replacement kits reduce downtime and expedite the repair process. The premium VC2G tool features a dual ball valve design that protects attached vacuum gauges and pressure probes and adds versatility for connecting hose lines and isolating system service ports. “Our VCRTs offer benefits that current VCRTs on the market do not have,” notes Jeb Ball, vice president of sales and marketing at Fieldpiece Instruments. “We collaborate with techs to understand the pain points and develop solutions that enhance their jobs. The VCRT line expands our arsenal of tools built for efficiency, versatility and durability, and underscores our commitment to innovations that allow technicians to work faster with more reliable results.” The new line of A2L compatible VCRT’s is being showcased at AHR Expo, January 22-24, in Fieldpiece Booth #S9334. Wholesalers are purchasing inventory now and product will be available to techs in April.

Four HVAC OEMs Meet Heat Pump Challenge America—keeping families warm during the coldest months and saving them money.” Heating and cooling buildings, homes, offices, schools, hospitals, military bases, and other critical facilities contribute to more than 35% of all U.S. energy consumption, driving carbon emissions that fuel climate change, jeopardize public health, and pollute local ecosystems. Heat pumps efficiently provides comfortable temperatures for heating and cooling homes and businesses in all climates, especially when homes are well insulated, and can also provide more efficient water heating. Unlike heaters that run on natural gas or heating oil, heat pump technology uses only electricity to extract heat from the air to heat and cool buildings and, when compared to gas boilers, heat pumps reduce on-site greenhouse gas emissions by up to 50%. Bosch, Daikin, Midea, and Johnson Controls will join previously announced partners Lennox International, Carrier, Trane Technologies and Rheem in the next phase of the Challenge, which is expected to involve the installation and monitoring of more than 23 prototypes in various cold-climate locations throughout the U.S. and Canada over the next year. With eight manufacturing partners successfully passing the laboratory testing stage in the Challenge, DOE is now turning to the nearly 30 state, utility, and other partners that were part of the original Challenge commitments to encourage the adoption of CCHPs. DOE will continue to work with partners to develop programs, incentives, education and outreach campaigns that help consumers better understand the benefits of these new designs. bit.ly/3SgQauX

WASHINGTON, D.C. Jan. 12, 2024—The U.S. Department of Energy (DOE) today announced that four additional heat pump manufacturers successfully produced heat pump prototypes as part of the Residential Cold Climate Heat Pump Technology Challenge, a DOE initiative to accelerate the deployment of heat pump technologies by supporting innovation and manufacturing. Launched in 2021, this initiative brings together public and private sector stakeholders to address technical challenges and market barriers to adopting next-generation cold-climate heat pumps—a key clean energy technology that can potentially save households $500 a year or more on their utility bills while also slashing harmful carbon emissions. The Challenge specifies that prototypes deliver 100% heating capacity without the use of auxiliary heat and with significantly higher efficiencies at 5 degrees Fahrenheit. Through the Challenge, DOE is working together with industry to accelerate widespread commercialization of efficient cold-climate electric heat pumps, which can provide clean heating and cooling for millions of American families and help meet President Biden’s goal of 100% carbon pollution-free electricity by 2035 and a net-zero carbon economy by 2050. “Deploying next-generation technologies like heat pumps is critical to the Biden-Harris Administration’s efforts to ensure that Americans have access to more affordable clean heating and cooling options—no matter where they live,” said U.S. Secretary of Energy Jennifer M. Granholm. “By supporting industry advancements, DOE’s Cold-Climate Heat Pump Challenge is helping get cost-effective clean energy technology into homes across

Report: HVAC & Water Heater Manufacturing Generated $211 billion, 704,000 Jobs in 2021 Arlington, Va. Jan. 2, 2024—The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) released the results of a 2021 economic analysis conducted on its behalf by the research firm Inforum. Using detailed census data, researchers concluded that HVACR and water heater manufacturers made significant contributions to the nationwide economy, directly and indirectly supporting 704,400 U.S. jobs, with a total economic output of $211.3 billion. These figures demonstrate that, despite the economic challenges of the Covid-19 pandemic, the industry maintained its status as a strong job creator. Direct employment increased by more than 10,000 jobs between 2017 and 2021, growing from 125,900 to 137,300, reversing a trend that began during the Great Recession of 2008-2009. This number excludes jobs created by other segments of the supply chain such as materials, energy, or shipping. The report found that manufacturers are, “especially important to states where activity is concentrated.” Texas accounted for the most direct and total output, generating $6.2 billion and $17.8 billion respectively. Other states with sizable output included Missouri, Georgia, and Ohio. California mainly benefited from total output, with the industry generating $8.3 billion in the state through manufacturing jobs, supplier jobs, and spending from industry wages. This report presents an economic analysis of the domestic heating, ventilation, air-conditioning, commercial refrigeration (HVACR) equipment and water heater manufacturing industry. The study provides information on recent trends within the industry, along with its contributions to the U.S. economy in 2021. The scope was defined using relevant shares of economic data to analyze manufacturing activity of: • Fans and Air Purification Equipment • Heating Equipment • AC and Refrigeration Equipment • Water Heaters.

This report measures three types of economic activity associated with HVACR equipment and water heater manufacturers: 1. Direct Impacts—Activity generated within the focus industry. In this case, the manufacturing of HVACR equipment and water heaters serves as the direct impact. 2. Indirect Impacts—Activity generated in other industries due to purchases (materials, energy, and services) by the focus industry through their supply chains. An Economic Analysis of the U.S. HVACR Equipment and Water Heater Manufacturing Industry 3. Induced Impacts—Activity generated by spending linked to income earned from direct and indirect production. When indirect and induced impacts are included, the industry supported 456.6 thousand jobs and generated $144.4 billion in economic output in 2021.

Pre- and Post-Pandemic

Employment

The report authors describe how sales of HVACR equipment and water heaters grew moderately in 2018 and 2019. A mild contraction in 2020 highlighted the resilience of the industry during a period of pandemic-related turmoil and uncertainty. Sales rebounded in 2021 as normal conditions resumed. As defined in this study, sales grew by an average annual rate of 3.4% between 2017 and 2021. Following an extended period of job reductions, the industry began adding jobs following the Great Recession of 2008-2009. This trend continued in recent years, with employment increasing by more than ten thousand between 2017 and 2021; total jobs in the industry increased from 125.9 thousand to 137.3 thousand over this span.

According to current estimates, total jobs increased by more than ten thousand between 2017 and 2021, increasing from 125.9 thousand to 137.3 thousand. Recent growth reflects a continuation of trends dating back to 2010 when the industry was still recovering from the Great Recession. Total employment growth accelerated for three consecutive years, including 3.7% growth in 2020, before moderating in 2021. While each industry segment recorded gains between 2017 and 2021, the bulk of the growth (+9.1 thousand jobs) was observed in the ‘AC and Refrigeration Equipment’ category. Additionally, this component recorded the quickest average growth over the period (+2.5%)

Industry sales

Improving the HVAC Service Experience ‘Everything we do, and every problem we approach is with the contractor and their customers in mind.’ — Guillaume Payen

Multiple aspects of a home’s HVAC system can be viewed by the home office professional. Images courtesy of HomeX

I

n parts 1 and 2 of this series, we shared news about the origins and expansion of HomeX—a remote diagnostics company that’s been making noise in the HVAC and plumbing service world—and the corresponding HomeX mission to acquire HVAC service businesses. This month we’re speaking with Guillaume Payen, president of the HomeX technology business, to learn some of the specifics on how the HomeX technology serves customers and service teams. Success in business is all about answers. Customers want answers to service issues and business owners want answers to questions surrounding efficient customer service, reduced callbacks and reduction in unnecessary truck rolls. The HomeX team is providing answers as each day it evaluates “the way we’ve always done it.”

As an engineer with a Master’s degree in aerospace engineering, Payen worked in the aviation industry for 12 years in roles spanning from engineering, customer support and sales for Bombardier, based initially in Montreal and then in Paris. He returned to his native Canada in July of 2019 to join HomeX, where he initially applied his engineering and sales skills as the Head of Business Development focused on the growth of Schedule Engine, which HomeX later sold to ServiceTitan. Since that time, Payen has been concentrating his efforts and expertise on HomeX’s remote diagnostic solutions, to create diagnostic solutions which benefit both service companies and customers in the home.

“My time at HomeX has allowed me to gain an understanding of how difficult and competitive the home services industry really is, but also how amazing and selfless the people in the trades truly are, I consider them real superheroes. I feel very grateful to be able to speak to contractors on a daily basis and have the opportunity to understand their pain points and what they go through day after day,” Payen said. “It has reinforced the fact that, as a technology company that is building solutions for the trades, we really must provide them with software tools that can make their lives easier, but also help them grow their businesses and be more efficient along the way.” Payen’s strengths are in leadership, fostering a positive and collaborative company culture, and always assessing problems and solutions from the customer’s perspective. He applies these principles daily to create an environment where his team thrives and the HomeX technology business grows. The HomeX visual assistance software is the heartbeat of the HomeX remote diagnostic solutions. It’s not an IoT product or sensor-dependent hardware. It is a software solution purpose-built for use in home services. It allows for a person on-site, whether it is a resident or a technician, to get quickly and easily connected to someone in the office at the contractor over web-based two-way video, meaning there is no need to download another app on your phone. By using the Home visual assistance software, contractors can deliver an improved customer experience, enhance operational efficiency and make better use of resources. “That means everything we do, and every problem we approach is with the contractor and their customers in mind. We’re building the experience, the features, the capabilities to address key pain points that contractors face on a daily basis as they try to grow their top and bottom lines, and give customers the experience they expect.” The team also knows how helpful this streamlined approach can be to attracting and retaining the best technicians in today’s labor-constrained environment.

Telemedicine for HVAC Payen likened the remote diagnostic method to telemedicine. “Teledoc took off and became a commodity.

We enable the same sort of experience but for home maintenance. The HomeX solution allows for a very efficient collaboration between someone on site—a resident or a technician, and someone in the office, such as a customer service representative, service manager, dispatcher, sales consultant or senior technician,” Payen said. “That allows the person in the office to guide the person on site using different tools such as a laser pointer, to capture relevant screenshots of the equipment, mark-up those screenshots, and capture accurate and relevant equipment information using our proprietary label understanding technology to better diagnose the issue upfront, to make sure the contractor can make a more educated decision on the best path to resolution. “If you’re able to remotely have eyes on the equipment, the environment and the symptoms being experienced, there is a high probability that you can immediately understand the potential root cause of an issue, which will help determine which parts to order, which tools to bring and which technician to dispatch, ensuring the right calls are being made proactively and allowing issues to be solved in one visit a lot more often,” Payen explained.

or equipment info. This solution will help contractors make better decisions on the most appropriate next steps to resolve the issue even before engaging in a potential video session. This solution is already integrated with ServiceTitan and will be launching for general availability by the end of this quarter. “The idea is to deliver the benefits of a Gen AI type experience but tailored for home services contractors so that residents can engage in a natural and conversational chat experience that would ask them the right questions about their problem. The questions would be tailored based on the equipment and the symptoms they’re experiencing. At the end of that Check-In session, a summary of the information is created and shared with both the resident and the contractor.”

ServiceTitan Option HomeX remote diagnostics software is fully integrated with ServiceTitan, which allows for video sessions to be launched directly from a job in ServiceTitan, and once the video call has ended, for all the information captured during the interaction to be automatically synced into the notes section of the applicable job in ServiceTitan. It’s easy and seamless for those ServiceTitan users to use the HomeX software as they basically never have to leave ServiceTitan to do so. However, a contractor does not need to have ServiceTitan to use the HomeX software and can benefit from the tool on a standalone basis. Payen said that when residents quickly engage with a contractor remotely over video, they immediately have the sense that they’re being heard, and the service is immediate. “They feel like somebody’s actually listening to their problem, and it’s very likely going to stop their search for another contractor because they have the confidence that you are on top of their issue and will be able to get it resolved efficiently,” he continued. The contractor on the other end of the HomeX video session can immediately start their diagnosis and go as deep as they would like to. It can stop at the simple gathering of relevant information by a CSR, to involving a service manager to go more in depth in the diagnosis, or even include a sales consultant should there be an opportunity to sell a new unit to the customer. Additional benefits that come to mind include a reduced need for a second opinion, and the ability to establish instant trust and credibility with a new customer. The next new exciting development Payen shared is the upcoming launch of a new product called “Check In”. It is an AI-powered chatbot experience, which leverages Generative AI, computer vision and HomeX’s proprietary knowledge graph to allow residents to provide more information about their issue in a natural and conversational way. Check-in knows when to ask for text, images

The HomeX discussion between the contractor’s office and technician or customer includes helpful photo enhancements drawn by the office assistant.

Another exciting HomeX product already released in Beta is called “Copilot,” an AI-powered tool focused on enabling contractor personnel such as CSRs, service managers and dispatchers to have access to accurate, trustworthy and reliable equipment information at their fingertips. “The information could be used by somebody in the office, or by a field technician, and based on the model number of a piece of equipment, Copilot will provide relevant information such as user manuals, warranty information, parts information and more. In addition, the user is able to enter a query which Copilot will understand and answer in the context of the equipment providing a trustworthy answer.” Payen said that answers to queries also include links to applicable pages in the manual along with any potential warnings in order to provide the highest level of transparency and trust with the answers being generated. “We want to be certain that whatever information is provided to the user is accurate because there’s no room for error in home services. As such, you get a direct answer to your query, plus access to the applicable supporting documentation. It’s another tool we offer to contractors to help them be more efficient as they try to diagnose and/or troubleshoot an issue with a customer,” Payen said. FEBRUARY 2024 | CONTRACTING BUSINESS | 21

WHAT’S NEW, WHAT’S NEXT? | BY MATTHEW TAYLOR, FUJITSU GENERAL AMERICA

Opportunity exists when moving beyond industry standard conventions and to unconventional, interoperable BMS technologies.

F

ounder of Nexus Labs, James Dice, PE, CEM, CMVP, recently penned a white paper titled “The Untapped 87%: Simplifying Controls Technology for Small Buildings.” In it, the author explains that a 20,500 square-foot building was retrofitted with a BMS (building management system) by the United States Department of Energy’s Pacific Northwest Laboratory in 2010. Within the first two years, this led to a 22 percent energy savings, and a “dramatic decline” in occupant comfort complaints. In addition to energy savings and improved occupant experience, a BMS can also significantly lower overall building operational and maintenance costs. In the case of HVAC equipment, most buildings are operated in a highly inefficient run-to-failure mode whereby support personnel are only made aware of equipment problems via complaints from occupants. This results in the need for a 24/7 rapid response capability and typically requires multiple site visits to determine the cause of the complaints and then to fix the underlying problem. A remotely monitored building with a BMS changes this dynamic. Through automation and notification, smaller facility management teams are enabled to more efficiently manage large portfolios of buildings. Mr. Dice’s paper goes on to explain that buildings smaller than 50,000 square feet represent 94 percent of commercial buildings in the US, 44 percent of electricity use, and 44 percent of total energy use. However, only 13 percent of commercial buildings under 50,000 square feet are equipped with a BMS.

Why? Economics prevents broad deployment. Building management systems are too complex and too costly for the average building owner, often to the tune of $5 or even $10 per square foot. Moreover, most BMSs require expensive annual service plans. As a result, there’s great opportunity to reduce energy consumption, increase indoor comfort, improve air quality, and lower building maintenance costs by moving beyond industry standard conventions and to unconventional, interoperable BMS technologies. In addition to developing new heat pumps to replace R-410A product offerings, Fujitsu General America has recently been busy creating one such alternative to the conventional BMS: AIRSTAGE Cloud, which provides BMS as a Service (SaaS). The highly versatile AIRSTAGE Cloud platform provides effective and efficient monitoring, management, and maintenance of Fujitsu VRF and Mini Split systems along with the ability to control and monitor any thermostatically controlled HVAC system, regardless of the manufacturer. By deploying highly automated SaaS based software services on a modern cloudedge computing architecture based on Amazon Web Services (AWS), AIRSTAGE Cloud provides the power of a traditional BMS without the prohibitive cost. The new plug-and-play platform automatically communicates with most deployed equipment. This solution makes it economically possible for all buildings to decrease energy consumption, increase health and comfort while decreasing building operational expenses. It automates all the costly installation, configuration, and operational building management functions. Fujitsu is not trying to make every device needed in the market. Instead, we’re focusing on enabling a world where the enduser can pick and choose the best equipment for their needs and have that equipment automatically recognized, commissioned and put into operation. Beyond that, the platform automatically coordinates the behavior of the equipment. The introduction of AIRSTAGE Cloud is a strong, deliberate movement away from the traditional, siloed behavior of BMS controls manufacturers. Take indoor air quality as just one example. Fujitsu does not manufacture any IAQ-specific components, aside from fresh air collars as an accessory to indoor units. With that said, AIRSTAGE Cloud offers nearly endless opportunities to seamlessly integrate and control IAQ components within a building. The Schneider 8650 room controller was the first IAQ solution to operate on AIRSTAGE Cloud. With an 8650 installed at a site, AIRSTAGE Cloud can monitor IAQ and IAC parameters via wireless battery-operated sensors. This provides monitoring and response to IAQ issues via alerting operators and even automatically coordinating equipment behavior to deal with problems. Again, it provides monitoring and control of any thermostatically controlled device. This includes more than 60 percent of all heating/air conditioning systems, including Carrier, Rheem, and York equipment, among many others. Essentially, all unitary equipment found throughout North America can now be controlled through one platform without the need for a conventional BMS. AIRSTAGE Cloud now includes two new apps, Site Manager and Refrigerant Cycle Monitor (RCM). Site Manager allows users of

an account to monitor and control a complete portfolio of sites, from one site to thousands. Account access can be assigned to any number of users. For example, the property owner and business staff can be added as administrative users, facilities support personnel and HVAC professionals can be added as technician users, and tenants can be added as occupant users. In addition, a user’s access can be further customized by a sophisticated permissioning system. RCM is a specialized diagnostic tool used to monitor and diagnose issues with AIRSTAGE VRF systems. It is predominantly used during installation and commissioning of VRF systems. It greatly reduces service times, labor, and repeat visits, saving all stakeholders time and money. By decreasing the cost of BMS equipment, installation, and operation to a fraction of traditional systems, Fujitsu is essentially bringing all the benefits of BMS to the masses. HVAC contractors, building operators and facility managers can finally deploy a cost effective BMS for any size project. The 87 percent of commercial space under 50,000 square feet in the United States finally has a BMS solution. Matt Taylor’s 35-year engineering career has been primarily focused on the design of high-speed data communication equipment and software systems, spanning from the early days of Ethernet on through to today’s modern internet.

DECARBONIZATION | BY TOM CASEY

1st Rule of Decarbonization is, Don’t Speak About Decarbonization Do no harm and always act in the best interests of the customer, which starts with NOT confusing them.

M

ore than ever, homeowners are tuned into station W.I.F.M., as in, “What’s in it for me?” Therefore, avoid using any confusing jargon or introducing any potential political land mines as you meet them. When it comes to “green” the client’s favorite flavor is almost overwhelmingly money, namely theirs. “Electrification” is really what we’re talking about when it comes to residential homeowners. Don’t say that word either! HVAC (another word no homeowner has a clue about what it means) is really all about comfort. If they wanted to cut utility bills to $0 they could just turn it “off”. Why don’t they do it and save all that moola? One word: C.O.M.F.O.R.T. Buying comfort systems is already a grudge purchase. Nobody really “wants” to buy one. We’re in the business, and I’ll bet either we and/or our staff don’t all own the latest, greatest systems available. Government mandates can possibly make it more “grudgey” because nobody likes to be told what to do. Electrification for HVAC all boils down to installing heat pumps someway, somehow. For any markets that are not already HPs, that makes a complex sale more complex. A confused mind always says “No”,

so we can run the risk of more objections than usual. Homeowners may need to think about it more, do more research and get more opinions. It’s also a basic pocketbook issue because whether heat pumps or hybrid or dual-fuel systems, they’ll likely cost more upfront, are more complex to maintain, and don’t last as long because they run year-round instead of seasonally. Yeah, yeah, “tax credits”, but that’s just more complexity for the average homeowner. Decarbonization isn’t really new, it’s just the latest shiny object in a new wrapper. The whole home approach has been around for decades, focusing on “Reduce Before You Produce” by optimizing all the sub-systems that make up the total home comfort system. Even the best, most efficient system, fossil fuel or electrified, is only as good as the installation itself. Bottom line – do no harm and always act in the best interests of the customer, which starts with NOT confusing them. Tom Casey is Chief Quality Officer at Griffin Service, Ponte Vedra, Fla. He was inducted into the Contracting Business Hall of Fame in 2022.

CELEBRATING 80 YEARS | BY TERRY MCIVER

Boomers Booming, Industry Growing

T

he war years were well behind us, and by 1950, heating, air conditioning and commercial refrigeration had become established as important cogs in the wheel of commerce. And that included some of what at the time were out-of-the-ordinary applications. In these early years of the post-war “baby boom”, American life prospered, in ways reflected by expanding industries and communities. On the cover of the July 1950 issue are a group of bowlers who were participating in the 1950 American Bowling Congress tournament, held in Columbus, Ohio. Indoor temperatures were making it dif-

ficult for the kegelers to kegel, so Frigidaire brought in 14 five-ton packaged air conditioners. Each unit was installed in a 18-in. pit behind the bowlers, and all electrical and plumbing connections were grouped at the base of each unit. Temporary rubber drain pipes were used to connect the units to the water main and drain pipes. Strike!

Early “Mission Critical” The “automatic electronic computer”—also known as a mechanical brain — was developed at UCLA, where 35 tons of packaged air conditioning was installed to keep the first generation of computers cool and operating without fail. Other equipment at the Institute of Numerical Analysis

included more than a dozen electrical computing and card punching machines. Cooling for all of this was provided by seven five-hp GE air conditioning units. The photo below shows one of the units used to cool the “brain machine” lab. Many brands today incorrectly think it doesn’t pay to advertise, but that wasn’t the case in the 1950s and for 50 years forward. Honeywell was among the leading advertisers, with monthly ads for the fantastic and functional Honeywell thermostats taking lots of space. Notice the familiar keywords: “sell” “install” and “reduce call backs.” Products change over the decades, but key principles remain. Larkin is now part of Heatcraft Refrigeration Products. In its early years it promoted a comprehensive line of air conditioning units, heat exchangers, coils for residential air conditioning, water-saving cooling towers and more. BOHN promoted its dedication to engineering quality into each of its PTAC units.”Versatility and compactness in a slim 81/2” width are featured in all BOHN-AIRE Models.” With a new name, Commercial Refrigeration and Air Conditioning Magazine was dedicated to helping contractor-dealers grow their air conditioning businesses. In 1950, the staff ran a threepart “Sales Symposium for Cooling Contractors.” An article by publisher Irving B. Hexter focused on positive actions. Here’s an excerpt: Give Your Salesmen Something to Sell: “If a manufacturer has a weak line, throw it out and replace it by another line. It isn’t always true that the line with the longest discount is the best line, because sometimes the lines with shorter discounts will sell more readily.

“When your salesman goes into a hotel, there are 13 things he can sell a hotel in the refrigeration line. But does he know it? Have you trained him to find out for himself what he can sell a hotel? “Supposing he’s called into an ice cream plant. There are 11 things he can sell in an ice cream plant. Let him find out what they are, and then let him keep suggesting this to his prospect, because somewhere along this line he might find a soft spot.” Moving forward to 1961, our Service Clinics got their start in these early years. And the technology is so much like today, only with a different look. An article on the volt-amp-ohm tester, “your serviceman’s best friend”, displayed four different ways to use it. Before the advent of the AHR Trend Report, association executives shared predictions for the year to come. To accompany the “Review and Forecast” survey shown earlier, five association leaders shared their views on the coming 1962 business year. These should sound familiar. Nice to see their comments are free of any mention of environmental panic and government interference. Walter McCarty, president, Refrigeration and Air Conditioning Contractors Association: “Qualified refrigeration and airconditioning

contractors would continue taking a larger share of the available business away from other contractors not primarily in this business. This trend started on the west coast and is not taking hold in the Midwest. Two reasons: some of these other contractors have not found our business profitable and many customers are returning to the qualified refrigeration and air conditioning contractor because By the 1960s, the magazine’s name was again changed, to The Refrigeration & Airconditioning Business, to reflect the expansion of residential and commercial air conditioning in the USA.

of dissatisfaction with the type of jobs they got from contractors not principally in this field.” Ray K. Serfass, president, Air-Conditioning and Refrigeration Institute (ARI): “Housing starts will be up modestly from about 1,300,000 to 1,375,000. Commercial construction is rising even now, and will continue to do so. Industrial construction is rising. All manufacture of durable goods is expected to rise.” E. Peter Sorensen, president, Air-Conditioning and Refrigeration Wholesalers. “Most wholesalers experienced a business slump in the first six months of 1961 due primarily to inclement weather and the general slowdown in the national economy. Last August our association started a monthly study of sales trends for our members. These reports have indicated a general rise in sale over the same period of 1960. With an improved economy and better weather conditions, sales should continue to grow next year.” Donald D. Denny, president, National Commercial Refrigeration Sales Association: “Business looks good and dollar profit also should be good although profit percentage may be down. Today’s picture is more volume and smaller margins. Competition is keen. Our business will be up because more and more of the smaller food market chains and voluntary groups are realizing that they can buy from a good distributor at less than they can buy direct.” Charles W. Lockhart, president, Air Moving and Conditioning Association: “Most of the manufacturers comprising our membership anticipate an increase in business for 1962. Profit increases are difficult to predict, but generally should be higher.” Next: “the modern supermarket” brings increased products and opportunities for installing and servicing contractors, and HVAC continues to grow.

PRODUCTS, TRENDS, AND SERVICE AND BUSINESS MANAGEMENT INFORMATION

Let the Refrigerant Phase-in Begin! Evaluating next-generation refrigerant alternatives in established and emerging applications By Jeff Lichty, Copeland

D

espite years of speculation and uncertainty, the phasedown of hydrofluorocarbon (HFC) refrigerants has officially arrived in the United States. For food retailers, it’s no longer a question of “if” it will happen, but rather when they will need to act. It also means they will soon be deciding which alternative refrigerants will become the foundations of their future refrigeration strategies. Unlike the previous generation of commercial refrigeration equipment, there is no one-size-fits-all approach that will solve most retailers’ requirements. Proven eco-friendly refrigerants CO2 (or R-744) and R-290 (aka propane)—as well as emerging A2L options—are among the most likely successors capable of meeting needed global warming potential (GWP) reductions. Although the entire industry is going through this refrigerant transition together, each retailer will experience their own unique journey. Equipment and architecture decisions should not be taken lightly, as they can impact your operations for the next 10–20 years. It is critically important to align refrigerant choices with your company’s long-term operational and sustainability goals.

Regulatory and sustainability drivers Retailers in California were among the first to make the transition in the U.S., largely in response to HFC phasedown mandates set forth by the California Air Resources Board (CARB). The passing of the American Innovation and Manufacturing (AIM) Act in 2020 laid the groundwork for an HFC phasedown on the federal level, following the guidance of the Kigali Amendment to the Montreal Protocol—an international treaty ratified by more than 150 member countries. Under the authorization of the AIM Act, the Environmental Protection Agency (EPA) has proposed the next phase of HFCreduction rulemaking, which sets the stage for the emergence of lower-flammability A2L refrigerants and increased charges of R-290 (subject to use conditions). Finalized in 2023, the EPA’s Technology Transition Rule established sector-based GWP limits and HFC refrigerant restrictions that will drive the use of lowerGWP alternatives, such as A2Ls.

This rule follows the guidance of the Underwriters Laboratories (UL) 60335-2-89, 2nd edition product safety and ASHRAE 15 equipment design standards, which include provisions for the safe use of A2L refrigerants in self-contained, factory-charged units and remote, field-charged refrigeration equipment. UL 60335-2-89, 2nd edition also includes guidance for increased charge limits of R-290 in self-contained refrigeration units and commercial ice machines. The EPA recently introduced new listings and use conditions for lower-flammability A2L refrigerants in commercial refrigeration under its proposed Significant New Alternatives Policy (SNAP) Rule 26. Combined, the EPA’s Technology Transitions Rule and SNAP Rule 26 proposal are key efforts in establishing a new era of lower-GWP refrigerant technologies. At the same time, environmental, social and governance (ESG) initiatives are prompting many companies to pledge operational sustainability targets over the coming years and decades. Because refrigerants are a potentially significant contributor to greenhouse gas (GHG) emissions—both directly from leaks into the atmosphere and indirectly from their impact on energy-efficient performance—selecting a next-generation alternative is among the most important sustainability decisions a company can make.

CO2 growth in North America CO2 refrigeration technologies have been adopted successfully throughout the world for nearly two decades. With a GWP of 1 and zero ozone depletion potential (ODP), CO2 is a sustainable alternative that is poised to play a key role in the U.S. refrigerant transition. Copeland has been developing CO2 system technologies for more than a decade, including compression, controls and components integrated to deliver seamless performance and help simplify CO2 refrigeration applications. CO2 systems and components are designed to manage its inherent high pressures, while R-744’s unique thermophysical characteristics present new opportunities to leverage reclaimed heat for hot water, indoor heating and other repurposing strategies.

Large, centralized CO2 systems For large retail outlets, CO2 transcritical booster (TCB) systems provide a centralized, all-CO2 strategy for both medium- (MT) and low-temperature (LT) loads. Although early CO2 TCB systems proved to perform well in cooler climates, modern CO2 TCB systems utilize new design approaches to optimize system performance in warm weather conditions as well. When considering a new CO2 TCB installation, food retailers should factor in utility costs—including electricity and water—and select a design optimization strategy that delivers the lowest total cost of ownership (TCO) in their region. Considering that monthly electricity rates are often driven by peak consumption periods, retailers with installations in high-cost kW/hr regions should do everything possible to minimize high peak usage scenarios.

The expanding potential of R-290 Over the past decade, the natural refrigerant R-290 has emerged as a viable low-GWP (GWP = 3) alternative, especially in smaller, selfcontained refrigeration units that don’t require large refrigeration loads. Today, most retailers are familiar with R-290’s widespread use in spot merchandising applications, such as reach-in display cases, beverage coolers, ice machines and ice cream freezers— which don’t require large refrigeration loads. Although R-290 offers proven sustainability and performance benefits, its A3 “higher flammability” classification must be taken into consideration. To mitigate R-290 safety risks and address safety concerns, the governing bodies that regulate the safe use of refrigerants in the U.S. have long established a 150 grams (5.3 ounces or 0.33 pound) maximum charge limit. The revised UL 60335-2-89, 2nd edition standard approved higher charge limits that potentially could expand the size of R-290 cases, raising the charge limits on commercial self-contained, plug-in displays based on whether they have an open or closed design: • 500 grams for open appliances (without doors) • 300 grams for appliances with doors or drawers. It’s important to note that currently in-progress SNAP 26 proposals—as well as model and building code updates—must first be approved before the industry can implement these higher R-290 charges. For now, retailers should be aware that the potential for larger-capacity, self-contained, R-290 units is on the horizon. Copeland is qualifying its R-290 compression lines to enable these larger charges and help OEMs to initiate their new equipment design cycles. Our variable speed Copeland™ scroll compressors deliver twice the capacity and higher speeds, enabling up to 7 HP systems with the anticipated charge limit increases.

Preparing for the emergence of A2Ls A2L refrigerants have long been recognized as potentially viable alternatives to high-GWP HFCs. A2Ls are composed of multiple chemical components—including those with high hydrofluoroolefin (HFO) content—resulting in a wide range of GWP ratings, including those below 300 and 150 GWP regulatory thresholds. Achieving these low-GWP levels results in a degree of flammability, warranting the A2L “lower flammability” classification, which will require the use of proper safety management and risk mitigation strategies. Leak detection sensors, proper ventilation

and safety shut-off valves may be required in some remote systems with larger A2L refrigerant charges. Not only is Copeland qualifying our compression lines for use with A2Ls with high HFO content, but we are also developing advanced leak detection sensors and controls technologies to help retailers ensure A2L safety, preserve their refrigerant investments, and maximize system performance. Select A2L-qualified compressor models are available for sale today, while samples of all compressors within the A2L qualification process (and their performance data) are available on request. Our new Copeland variable frequency drives, EVM and EVH series, have also been qualified for use in systems with flammable A2L and A3 refrigerants, per relevant component safety standards for commercial refrigeration. A2L refrigerants fill a much-needed niche within the refrigerant landscape. With charge limits exceeding those proposed for R-290, A2Ls also deliver approximately 20 percent more compressor capacity than R-290. Thus, A2Ls offer a potentially higher-capacity alternative in self-contained applications and a lower-GWP solution for higher-charge distributed and/or remote system applications, such as outdoor condensing units (OCUs) or mini-racks used in smaller-format outlets. These unique characteristics could also provide lower applied costs than CO2 in comparable applications. A2L adoption in U.S. commercial refrigeration is still in its early stages, as regulatory approvals and safety standards and building codes are currently being finalized and/or adopted. Regardless of which A2L applications may become more commonplace, A2Ls will give retailers another high-performance, low-GWP option for their next-generation refrigeration portfolios.

Make the most informed refrigerant decisions As retailers plan their refrigerant transitions, many are looking for guidance on how to phase out their high-GWP HFC infrastructures while phasing in lower-GWP, more sustainable replacement refrigerant strategies. Copeland has the application expertise, product portfolios and value-added services to help retailers make successful and cost-effective refrigerant transitions. We recently completed two extensive research projects designed to help retailers evaluate which refrigerants and infrastructures align closest with their operational and sustainability goals. Our Total Cost of Ownership (TCO) study can help you to compare various low-GWP refrigerant architectures to determine which strategies deliver the most optimal short- and long-term cost savings and GWP reductions for your operation. For those retailers exploring CO2 TCB systems for new store installations, our “CO2 Climate Study” can provide guidance on selecting a design optimization strategy that can help you to maximize energy efficiencies and deliver the lowest TCO per your unique climate zone and utility considerations. Regardless of where your company is on its refrigerant transition, Copeland is ready to help you evaluate emerging refrigerant solutions and take the next steps on your journey. To learn more about Copeland’s low-GWP, alternative refrigerant-based solutions and application expertise, please visit the emerging refrigerants section of our website.

hen you make reservations at the upscale restaurant, you order the ideal food with the perfect flavors, and everything is topnotch. But, if a tiny detail was left off, the experience is no longer excellent but just mediocre. This is the life of a brand. Whether you sell vacation homes, shoes, new training software, or a home service, branding is felt in all aspects of the experience with your company. We must focus on our customer experience to enhance our brand image. Branding is traditionally thought of as an icon or a logo, and while this is true, it’s only a piece of the experience, not the entire experience. We must see the bigger picture of our brand’s customer experience to see an authentic winning culture. The first interaction with your company matters when homeowners look to decide on their contractors. We must consider how a client might contact you and how that happens with all the available technology. Is your website friendly and easy to navigate, or is it too busy and clunky with chat options, “book now” options, get financing now options, etc? Or, is it nice, clean, and easy to contact you how the client wishes to reach out? Are your social media channels filled out with your contact information so you are easily reachable? If they love your contact, is there a link in your captions to allow them to schedule quickly? Does your customer service team answer the phone with confidence and empathy?

We want to WIN the ring! Like a spider web, we have them in our “web” of greatness once they call us. All these things are a potential customer’s first impression of your company. They are the brand. This leads down a rabbit hole because, technically, their first impression of your brand was through advertising. If your billboard looks old, faded, and tattered, your company must be withered and worn in the eyes of potential clients. If you have a boring radio ad or generic truck wrap, you aren’t memorable, nor will their experience with your brand. We must strive to be different, but with “different” comes investment. It’s hard to dare to be different when you can barely make payroll. You must invest in your brand and your company’s future. Whether we like it or not, our community has already decided what type of company we are before they do business with us. Their interaction with your company at community events, doing charitable work, and your visible presence already invokes emotions. This is how mascots help win the relationship game with potential new customers; it’s a differentiator and memorable for your community. You need to make yourself unforgettable and relatable. That’s the secret sauce on any plate of advertising. Eat it up, guys. It’s the recipe for brand success and brand longevity. Get brave, get risky, and GROW your business.

n the rapidly evolving realm of marketing in the trades, the strategic integration of Artificial Intelligence (AI) emerges as the basis that sets innovative businesses apart from the rest. Harnessing AI in marketing not only supercharges automation but also significantly enhances operational efficiency. Marketing is equal to operations; the whole ship has to sail together. We are always in a landscape where adaptability is key, and marketing departments that hesitate to embrace AI are at risk of being unable to match the agility and effectiveness of their AI-empowered counterparts.

Streamlining Operations with AIDriven Automation The transformative impact of AI begins with the seamless automation of routine operations. All

tasks take time and time is money that can hit the bottom line, ask yourself what are the repetitive tasks that can be automated. What are the tasks that we are currently doing where we can leverage AI? Marketing teams are often inundated with repetitive tasks, from data analysis to campaign optimization, creation, and lead management. AI steps in as the silent orchestrator, automating these tasks with precision and speed. This not only eliminates the drudgery associated with manual work but also empowers marketing professionals to redirect their focus towards more strategic initiatives and work towards the goals of the business to always become more automated and efficient at scale. Remember, AI will build the outline for you, the human element is still needed to edit, validate, and craft the output.

Precision in Targeting Through AI-Enhanced Personalization

Leveraging AI for Dynamic Content Creation Across the Customer Journey

AI is a game-changer when it comes to crafting highly personalized marketing campaigns tailored to the unique preferences of your audience. By leveraging vast amounts of data and behavioral insights, AI algorithms can discern patterns and predict individual preferences. This allows for the creation of targeted messaging that resonates with the audience, leading to increased engagement and higher conversion rates.

Integrating AI into content creation transforms the customer journey into a dynamic and responsive experience. From personalizing content to addressing objections and predicting engagement, AI becomes a strategic partner in nurturing the “yes” of conversion and adeptly rehashing objections, propelling businesses towards sustained growth.

Agile Decision-Making with Real-Time AI Insights

As AI continues to evolve, its integration becomes synonymous with future-proofing marketing strategies. The adaptability and scalability inherent in AI-driven solutions position businesses for sustained success in the ever-changing landscape of marketing and advertising. Marketing departments slow to adopt AI may find themselves struggling to keep pace, potentially compromising their competitive standing in the long run. AI in marketing for the trades is not just a tactical choice but a strategic imperative. Businesses that harness the power of AI position themselves for increased automation, operational efficiency, and adaptability. The future belongs to those who seamlessly integrate AI into their operations and reach new heights.

In the dynamic and ever-shifting macroeconomic environment, timely, data-driven decision-making is not just an advantage; it’s a necessity. AI facilitates real-time data analysis, providing marketing teams with actionable insights for agile decisionmaking. Businesses incorporating AI can adapt swiftly to market trends, shifts in consumer behavior, and emerging opportunities. This agility positions them to seize opportunities and navigate challenges, gaining a competitive edge over competitors still reliant on slower, manual processes.

THE LAST WORD BY DOMINICK GUARINO

A New Era of Collaboration

R ‘We must learn to work together towards our shared goals.’

ecently I reflected on my nearly 40 years in this industry and the changes and cycles we’ve undergone. Interestingly, while technology advances and becomes more sophisticated, we continue to go through repeating cycles. Take heat pumps for example. They were all the rage in the 1970s and 80s, not just in southern climates but in the north as well. We soon discovered many customers weren’t happy with heat pump systems blowing colder air and wanted their gas-fired furnaces back. Today, 50 years later, there is a resurgence of interest in heat pumps, primarily due to the decarbonization and electrification movement. The equipment itself is significantly better, more efficient, and can provide warmer comfort, even at low outdoor temperatures. These newer heat pumps, however, present us with new challenges, particularly in existing homes where many don’t play well with old air distribution systems—especially those designed for gas furnaces. These issues, coupled with contractor and consumer fear about grid reliability, means we must be able to offer more climate resilient solutions to gain consumer trust. Other technological challenges ahead include adoption and service of the new A2L refrigerants, the new M1 equipment standards, inverter technologies, compatibility with smart home technologies, and so much more.

Back to Working Together In the late 1980s and early 1990s I recall a much stronger environment of collaboration within our industry—particularly among contractors. Organizations like ACCA were helping to build this with more experienced contractors sharing knowledge with less seasoned ones just starting out in business. Doc Rusk, for example, was among the emerging industry leaders who shared everything about his company with anyone who would listen. We had many great thought leaders like Wallace Lee, Tom Mutz, Ron Smith, Tom McCart, Jackie Rainwater, and Buck St. Cyr—just to name a few, freely sharing their wisdom. I encourage you to go into the Contracting Business magazine archives and read their articles—I think you’ll find them still very relevant today. While there are some great up-and-comers impacting our industry today, it feels like until recently we’ve had a drought of sincere and open sharing. Organizations like ACCA are working on rebuilding more sharing and collaboration—especially at the local level, but we still have much work to do.

A New Movement With the advent of social media channels and HVAC professionals starting podcasts and streaming on Facebook, YouTube, and even Instagram and TikTok, we are seeing a resurgence of collaboration that is helping the HVAC community to get stronger both globally and locally. These may be the very channels we need to bring back the spirit of collaboration and sharing our industry urgently needs to face the challenges ahead. At NCI’s High-Performance HVAC™ Summit last year we talked about a new era of collaboration emerging among contractors, HVAC equipment and test instrument manufacturers, software companies, educational organizations, and other professionals—all interested in a common goal: To raise the bar for our industry and provide consumers with better performing indoor comfort systems. This excitement and new energy were palpable last April, and have continued to build. We felt it again at AHR this January with many products on the show floor aimed at improving performance. We felt it in many of the educational seminars. NCI presented five sessions related to this movement, and we also participated in two panel discussions. We will provide links to the slide decks as well as video of the two panels—look for these soon at NationalComfortInstitute.com. We also held our first High-Performance HVAC Hangout reception at AHR with more than 120 industry professionals. We plan to grow this event significantly at AHR 2025. Stay tuned! The HVACR Symposium hosted by HVACR School. took place in early February, but recordings will be available online at HVACRSchool.com. Of course, we hope to see you at NCI’s High-Performance HVAC™ Summit (GoToSummit.com), this September in Asheville, NC. You will get a chance to be part of the same movement Summit has been fostering for the past 20+ years! To get this industry ready for the challenges and opportunities ahead we must learn to work together towards our shared goals. To quote a common cliché, a rising tide does indeed raise all boats!
