his is my final column as editor-in-chief and director of Internet content for Contracting Business. I will work on the January 2025 issue, and will then be moving on. I started here in April of 2005. I will say one more “thank you” to Mike Weil for hiring me, which enabled our family to move back to the Cleveland area, where my wife and I were born and raised, and where I previously worked in publishing for 10 years. From that first interview at a Donato’s Pizza in Parma, Ohio, we fast forward to this moment. Mike Weil, Kate Kelly and Pete Grasso remain involved in the HVACR industry. Mike and Kate are with National Comfort Institute, and Pete Grasso is with Heatcraft Refrigeration Products. Ron Rajecki is a Cleveland-based freelance writer. Once I started here, I was soon speaking with and meeting many of the “greats” of HVACR, either by phone, during contractor visits, and during national events, including our Comfortech Show, which Dominick Guarino, Jeff Forker started in 1996, with the help of Mike Weil and an event team, and which ran for 19 years. Who to thank? I have a long memory, and until the Lord takes it away, I will never forget them for their help, friendship and contributions: Mike Weil, Ron Rajecki, Kate Kelly, Pete Grasso, Valerie Stakes, Steve Palmison, Connie Conklin, Andrea Begany-Garsed, Marge Dietrich, Mike Eby, Steve Spaulding, Rob McManamy, Scott Arnold, Beverly Beckert, Charlie Greer, Dominick Guarino, Charlie Greer, Tom Casey, Jr., Drew Cameron, Steve Miles, Chris Peel, Randy Roberts John Schwartz, Mark Klein, John and Dan Vastyan, Wesley Schmidt, Holt, David Richardson, Don Gillis, Vince and Laura DiFilippo, Drew Barbosa, Louis Hobaica, Matt Michel, Chris Peel, Mike Smith, Lori Quillen-Bell, Eddie McFarlane, the teams at ACCA, Service Nation, EGIA and WHVACR, all three of which produce excellent events; Bill Almquist, Larry Taylor, Steve Saunders, Dewey Jenkins, Martin Hoover, Stan Johnson, Steve Howard, Brian Stack, Gary Upton, Mitch Cropp, Lee, Betsy and Michael Rosenberg, Josh Kahn, Ken Goodrich, Dick Starr, Vicki and John LaPlant, John Owens, and those I knew who have passed away: Bob Mader, Rob “Doc” Falke, Ron Smith, Pat Rucker, Joe Fristik,
and Steve Wright. Much thanks, and good luck to our current sales team: Randy Jeter, Bill Boyadjis, Brian Sack, Ellyn Fishman, Jay Thompson, Steve Suarez and David Sevin. Connie Conklin, Susan Lakin and Julie Whitty provided graphic design support at various times during my 20 years, Julie most recently, with some pinch-hitting by Meg Fuschetti.
I called some people. One was Bill Almquist, past owner and president of Almcoe Refrigeration in Dallas, which is now owned by Smart Care. Bill is among my favorite industry people. He was one of the contractors we brought together for our series of Refrigeration Roundtable summits in the mid- to late-2000s. Not to be self-serving, but Bill said, “You’re living the dream, in large measure due to the kindness you showed to us and to everybody you came in contact with. That is more valuable than any fortune.” That meant a lot to me.
During my 20 years here, I never spoke with anyone who wasn’t anything but welcoming and helpful. You who remain should take that as a compliment and testament to your own value systems.
I especially want to thank my wife, Terrie, for her love and support all the way through.
Additional changes for 2025: Our 2025 class of contractor “Influencers” will be Michael Rosenberg, Tucker Yarbrough, Andy Hobaica and Vince DiFilippo.
Alyssa Rogers, Vice President of Rogers Heating & Cooling, Boston, Mass., will now appear every other month in the space previously occupied so well for 30 years by Dominick Guarino, CEO of National Comfort Institute. This change was made to provide more regular commentary from an additional HVAC contractor.
I won’t miss planes and airports, but I will miss the shows, and you, the people of HVACR. Contractors, please support the new editor with emails, observations from the field and perhaps you can write some business management and project articles and participate in contractor podcasts.
I realize everyone is busy, but please try to help in any way you can.
Wishing you all continued success.

Cold climate heat pumps (CCHPs) developed as part of the challenge will enter commercial production as soon as this fall, manufacturers say. Building upon the success of the residential challenge, DOE is now working with nine heat pump manufacturers to advance rooftop units (RTUs) for commercial buildings through a new technology challenge. This initiative is part of the Commercial Building Heat Pump Accelerator, in which DOE is working across the supply chain for commercial heating, ventilation, and air conditioning systems to advance the adoption of heat pump RTUs.
Heating and cooling buildings account for 40 percent of U.S. greenhouse gas emissions. Next-generation CCHPs can potentially reduce household utility bills while also slashing harmful carbon emissions. For commercial buildings, heat pump RTUs are estimated to reduce greenhouse emissions and energy costs by up to 50 percent compared with conventional RTUs fueled by natural gas. But while overall demand is growing, adoption has lagged in cooler climates because of reduced performance in cold weather. The technology advancements fostered by the Residential CCHP Challenge and Commercial Building Heat Pump Accelerator are intended to help the United States meet the Biden Administration’s goal of 100 percent carbon-pollution free electricity by 2035 and a net-zero carbon economy by 2050. It is too early to say if that goal will change under President Trump. Visit contractingbusiness.com/55237544 for more information.
The U.S Department of Energy (DOE) announced on October 23 that all eight manufacturers in the Residential Cold Climate Heat Pump Challenge completed rigorous product field testing to demonstrate energy efficiency and improved performance in cold weather. Those manufacturers are: Bosch, Carrier, Daikin, Johnson Controls, Lennox, Midea, Rheem, and Trane Technologies.
You’ve had successes and possibly some missteps in 2024. But take heart in knowing you can review and improve for 2025.
ow do you evaluate the experiences from the past year and turn them into actionable strategies for future success? Here is a methodical approach to evaluating performance, learning from failures, and making necessary changes to thrive in the coming year.
The first step in using past experiences is to take a hard look at what worked and what didn’t. For most contractors, this can be a daunting task because it involves acknowledging failures, such as a product, service, or new processes that flopped. Maybe you launched a new dispatching system, experimented with an innovative customer outreach program, or introduced a new sales tool that didn’t pan out.
More often than not, failure in any new initiative is tied to execution, timing, or support systems that weren’t aligned for success. Read on to see how to analyze these missteps and turn them into valuable learning experiences.
When a project flops, consider the many valuable lessons learned through the failure. You invested good time and money on the idea, so don’t throw it away. Ask the following questions:
Was it a market fit issue? Did the new service actually address a customer need, or was it something you “thought” would work based on personal assumptions? Sometimes, a great idea is ahead of its time, or it targets a market segment that’s too small to make it viable. Look through the eyes of the potential customer to see if your idea has real merit. If the idea doesn’t resonate with your intended audience, it was dead before it even got started.
If you launched an advanced air filtration system but didn’t see the interest you expected, it could be that homeowners weren’t educated on the benefits, or they didn’t perceive IAQ as a priority.
Did internal systems support the change? Well-defined systems minimize chaos. If your internal processes aren’t ready to support the new service, it’s sure to fail. For example, if you invested in a new sales proposal presentation system expecting to reduce stress, increase average sales price, improve closing rates, and sell more jobs, but you experienced poor results, it might not be the system that failed, but rather your team’s attitude, preparedness or the lack of thorough training.
Was the new service adequately marketed? If no one knows about your new service, it’s destined to fail. If you rolled out a new maintenance program but didn’t see the uptake, it’s worth
reviewing whether your customer outreach efforts were adequate. Did you educate your homeowners about the benefits? Is there understandable information on your website or brochures? Were your techs trained to talk about it during repair calls and was a follow-up process in place?
Was there customer buy-in? Customers are unlikely to invest in solutions for problems they don’t perceive as affecting them. For example, you might have launched a premium maintenance plan with all the bells and whistles, but customers weren’t interested because they didn’t see the value compared to your basic “fix it when it breaks” services. In this case, the issue isn’t the service itself but perhaps the way it was presented.
Once you’ve identified the cause of the failed endeavor, gather and analyze relevant metrics. As my friends at NCI say, “if you don’t measure, you’re just guessing!”
Questions to consider:
• What percentage of customers signed up for it?
• Were there common characteristics among refusals?
• Did the service drive repeat business, higher margins, or improved customer satisfaction?
• Did internal processes (sales scripts, dispatching, training, etc.) align with the service’s goals?
If your sales team didn’t effectively promote the service, talk to them. Did they feel they had the right tools or incentives to push it? Did they receive any feedback from customers that could explain the low interest? The answers lie in the data.
Once you’ve identified the root causes, it’s time to adjust. The key here is to understand that corrective action doesn’t always mean abandoning the service or initiative altogether. Often, small tweaks can make a big difference.
If a service didn’t resonate with your target audience because of how it was marketed, consider repositioning it. For example, if your air filtration service didn’t gain traction, you could reframe it as part of an overall health and wellness offering, emphasizing benefits like allergy relief, reduced illness, and better IAQ.
Sometimes the service itself is sound, but your team wasn’t
equipped to execute it properly. Offering more training for your team can make all the difference. Consider running role-play scenarios to simulate customer objections and team response.
If price was a barrier to entry, consider adjusting your pricing strategy. You could offer a basic version of the service at a lower price point or create bundled packages that combine popular services with the under-performing ones to increase perceived value.
If the failure was a result of poor visibility, invest in stronger marketing efforts. Use email campaigns, social media, and in-person discussions during service calls to ensure that customers understand the value of the service.
As you plan for the upcoming year, set realistic, measurable goals based on the lessons you’ve learned. These goals should be SMART (Specific, Measurable, Achievable, Relevant, Time-bound).
If your goal is to grow a maintenance program that struggled in the previous year, your target could be: “Increase maintenance plan sign-ups by 25 percent within the first quarter by implementing a new marketing strategy and offering additional training to all technicians.”
Learning from the past year doesn’t end when the new year begins. Contractors need to continuously evaluate the effectiveness of their services, marketing efforts, and internal processes throughout the year. This means creating a feedback loop where you regularly check in on performance metrics, listen to team and customer feedback, and make data-driven adjustments on an ongoing basis.
Every failure is an opportunity to gain experience, and as an HVAC contractor, you have the advantage of a cyclical business where each year brings new challenges and opportunities. The key is to remain flexible, data-driven, and open to change, ensuring that every setback becomes a stepping stone toward long-term success.

Eliminate all guesswork when reviewing past performance. Metrics provide solid evidence you can use for the new year.
Was 2024 a good year for your business? The answer lies in the data. Metrics revealing patterns in customer acquisition costs, call response time, net profit, etc., allow HVAC contractors to evaluate their business’s performance honestly. Without a thorough analysis of this data, owners are left guessing and will likely miss opportunities to reduce costs, streamline processes, and maximize profit.
Whether your business thrived or faced challenges in 2024, analyzing your data can empower you to make 2025 your most successful year yet. Let’s explore how.
First, you must understand your company’s stage of development, as each phase presents unique challenges and opportunities. Newer companies may focus on building a client base, while mature businesses should concentrate on scaling operations and retaining customers.
Key performance indicators (KPIs), such as revenue per employee, gross profit margins, and cash flow, may help determine your company’s growth stage and readiness for expansion. Operational metrics, like revenue and gross profit per man-day,
can expose inefficiencies, enabling companies to pinpoint areas for improvement.
Once improvements are identified, set clear objectives, assign responsibilities, and establish a timeline for implementation, including deploying training or investing in better equipment. Understanding retention rates and job costing can also refine customer strategies, guiding businesses on potential service enhancements or pricing model adjustments.
Shifts in consumer expectations can inspire new business ideas. For example, if your customer base sought more energy-efficient, eco-friendly solutions in 2024, consider expanding your renewable energy portfolio to accommodate such requests in 2025.
Mature businesses might explore adding complementary services, such as plumbing or electrical work. This diversification of services strengthens customer loyalty and expands revenue opportunities.
Awareness of evolving financial incentives—rebates, tax incentives, and government programs—positions companies as trusted advisors and allows them to help customers save money.
Blind adherence to past strategies can stifle growth. Companies must be ready to pivot in response to competitors introducing
innovative technologies or adjusting prices. The most resilient companies tend to streamline operations and reduce overhead by embracing new technologies, such as automated scheduling and customer communications.
Successful business planning relies on analyzing past wins and failures. A post-mortem analysis can yield valuable insights by revealing specific areas for improvement. For example, reviewing financials might show that the project met its gross profit goals but fell short of net profit due to unaccounted expenses. This analysis enables leaders to set more precise financial guidelines for future projects.
Failures are just as instructive as successes. Examining missteps can lead to refined processes and updated training. Quick, transparent replies to customer feedback can foster trust and loyalty.
While historical metrics are useful, relying solely on them can stifle growth. Focusing on past KPIs can lead to complacency and missed revenue opportunities. For instance, if a service truck generated $20,000 in revenue, perhaps it could have yielded $30,000 with optimized routing.
Create a detailed action plan outlining innovative solutions and set ambitious, achievable goals for 2025. Consistently reevaluate performance and encourage creative problem-solving.
Using past metrics to forecast future activity is like mapping a journey: It provides a foundation with room for rerouting. By combining insights from past performance with a forward-looking approach, companies can build a flexible, data-informed strategy that adapts to change. The best path forward respects the lessons of 2024 while embracing the potential for innovation in 2025. This balanced approach positions companies to survive the future and thrive in it. The facts are in the figures—making the necessary adjustments is up to you.

Ken Goodrich began “The First Step” wellness initiative to support contractors across the USA.
K“We’re creating an online community that recognizes our distinct health challenges within our industry and helping one another navigate through them.”
— Ken Goodrich
en Goodrich is a well-known figure in the home services industry, recognized for his leadership roles at top brands like Goettl Air Conditioning & Plumbing, YES! Air Conditioning & Plumbing, and American Residential Services (ARS). With a career dedicated to running, acquiring, and enhancing home services businesses, this member of the Contracting Business HVAC Hall of Fame has driven hundreds of millions in annual sales for each company he oversees. His strategic prowess has brought numerous accolades, including spots on the Inc. 500 list. At age 10 he would hold a flashlight while his father repaired air conditioning units. Today, he’s a model for aspiring business leaders shaping their own strategies. Goodrich is passionate about nurturing the next generation of skilled professionals. He founded the J. Duncan Goodrich Air Conditioning Technology Institute and supports home services industry students through an endowed program at the College of Southern Nevada, as well as being active in industry associations such as the Southern Nevada Air Conditioning Refrigeration Service Contractors Association (SNARSCA). In 2023, Goodrich was appointed to the Nevada Workforce Development Board by Governor Joe Lombardo. “Supporting education and training for our future technicians is crucial,” Goodrich said. “We need a skilled workforce that is prepared for the changing landscape of this industry.”
The challenges of running a business can take a toll on health, particularly for leaders who often prioritize their companies’ profits and operations over their own well-being. This reality hit home for Goodrich after a personal health scare
that prompted him to reevaluate his priorities and advocate for wellness in the home services sector.
One evening while relaxing at home, Goodrich faced a severe health scare: his heart raced, his skin became clammy, and he struggled to breathe, making him fear for his life. Fortunately, Goodrich recovered quickly, but the incident was a wake-up call, revealing that despite his business successes and community contributions, he had neglected his own health.
With a determined focus on getting into better shape, Goodrich enacted a daily walking regimen, ultimately shedding over 100 pounds. This transformation not only revitalized his health but also inspired him to help others in the home services industry. Acknowledging the long hours and unhealthy habits many business owners and employees endure, he launched a wellness initiative called The First Step with Ken Goodrich, a Facebook group designed to support the well-being of home service professionals across the country.
With over 1,500 members, The First Step has evolved into a vibrant community where home services business owners and employees share their health journeys, uplift one another, and celebrate achievements. “This group goes beyond a wellness program; it has created a movement,” Goodrich explains. “We’re creating an online community that recognizes our distinct health challenges within our industry and helping one another navigate through them.”
The impact of The First Step has been significant. Members frequently share inspiring success stories, many attributing their motivation to Goodrich’s example. Jason Amato president, Pathway Partners Group noted, “I’ve maintained a 40-to-50-pound weight loss since October 2020. The inspiration from this group has significantly increased my walking miles.” He added, “Connecting with others facing
similar challenges has been a huge source of motivation, and I’m grateful for Ken’s leadership.”
Bill Cavanaugh owner and CEO of Cavanagh Electric remarked, “Ken Goodrich is an inspiring leader who balances a busy life with mentoring others in business and healthy living. His tough love approach, paired with genuine support, has transformed my health and my approach to business.” Similarly, Ryan Ruff general manager of Kliemann Brothers Heating, AC and Electrical expressed, “The First Step group has been amazing. Ken has been a fantastic motivator, always encouraging us even with his busy schedule.”
Goodrich’s initiative comes at a crucial time for the home services industry, which faces health risks due to its physically demanding nature. Industry data reveals over 37,000 injury and illness claims are filed each year. Many home services business owners are entrepreneurs and are experiencing tremendous revenue growth, causing many to focus on the wealth of their business, while perhaps neglecting the health of their employees. By promoting health and wellness, Goodrich aims to reduce these incidents and improve the overall quality of life. “Employees in good health tend to be more productive, and ultimately safer,” Goodrich states, emphasizing his belief that wellness should be a fundamental aspect of the home services sector.
Beyond personal wellness, Goodrich is cultivating a culture of care within the industry. His health journey underscores the importance of prioritizing well-being not only as an individual responsibility but also as a professional imperative. By encouraging others to take “the first step” toward better health, he advocates for a paradigm shift in how the industry supports its workforce.

As the HVAC industry makes progress with many changes that have taken place in 2024 and that are expected to continue through 2025, we offer another in our “What’s New? What’s Next?” series on HVAC manufacturer viewpoints. This month, we offer this commentary by Jason LeRoy, Director of Advanced Technology for Trane residential HVAC products, who describes the many advantages homeowners and HVAC contractors will find in today’s newest heat pump products. –ed.
Contracting Business: Jason, thank you for your time. With homeowners so accustomed to yearround comfort, how are today’s heat pumps meeting that need, now and in the coming years?
Jason LeRoy: With the accelerated manufacturing of cold climate heat pumps, heat pump technology can work efficiently all year round, even in severely cold weather. In many installations, an air conditioner and furnace can be replaced by a single heat pump.
CB: An added benefit is that today’s heat pumps can be easily integrated into a home control system.
JL: Yes, smart home technology allows for technicians and homeowners to easily control and monitor a system from anywhere, optimizing comfort settings and energy use. Trane’s control product, Trane Link, seamlessly connects to an HVAC system, making installation straightforward for technicians and sparing dealers from extensive retrofit concerns. Heat pumps are built for versatility, and integrate smoothly with smart home technology, giving users ultimate control and monitoring capabilities—this is especially important for areas with high or low humidity levels.
CB: Today’s heat pumps are also cost efficient for dealers and techs alike, correct?
JL: That’s right. Heat pumps operate at a price point that’s similar to conventional heating and cooling options. Heat pumps offer a cost-effective alternative that helps with dealer margins without sacrificing quality or functionality. Their high efficiency means potentially fewer maintenance calls and helps with increased customer satisfaction.
CB: As someone who’s been immersed in heat pump product development, are there multiple heat pump models to choose from now offered by Trane?
JL: Trane heat pumps are currently available in three tiers, as a result of the new naming and tiering system that we rolled out earlier this year, so consumers could better understand Trane’s
new models. There’s a basic, single-stage heat pump which in 2025 will incorporate a more sustainable, environmentally friendly low GWP refrigerant R454B This is an excellent choice for an energyefficient home. It is an all-electric cooling and heating solution, but it does allow the homeowner to pair the heat pump with a gas furnace, which we would call a dual fuel system. In that case, the heat pump is the primary heat source for the home, and then the furnace will kick in when the outdoor temperatures get very low, when outdoor temperature plummets, for example. But with this type of system, you can get heating and cooling efficiency that can help save money today compared to what they have.
If you bump up to the next tier, Trane offers a two-stage heat pump, which uses a two-speed compressor and a variable speed indoor blower to keep the home comfortable all year long. The two-speed unit provides a really good mix of value, comfort, and efficiency. That model is also available to be paired with a furnace in a dual fuel solution, for the climates that need it. Not all climates need dual fuel.
Our premium tier heat pump is the Trane TruComfort™ Variable Speed heat pump. That heat pump helps provide ultimate comfort by basically running at whatever speed, or heating or cooling capacity the home needs at that moment to stay comfortable, since heating and cooling loads vary significantly throughout the day throughout the season. It has approximately a 75 percent turndown ratio, which enables it to run from 25 percent to 100 percent capacity in increments of 750 steps, so it’s essentially infinitely variable.
In that type of system, the compressor, the indoor blower and the outdoor fan work together in harmony to provide heating and cooling output that’s needed to help provide a consistent, comfortable living environment in an efficient way. It also features Trane Link Connectivity. This means that your system’s going to automatically charge itself, it’s going to configure and calibrate the components for reliable performance throughout the life of your product.
Trane’s TruComfort variable speed products can be used as a heat pump today and will satisfy the vast majority of the heating needs for the vast majority of the United States.
We actually are able to overspeed the compressor in heating mode. We go up more than 50 percent relative to cooling output, and that gives you an extra 50 percent capacity. So that’s something a single- stage or even a two-stage system doesn’t have the ability to do, because those products are just running at a constant 3600 hertz output speed.
All three of these tiers have reliability built into every heat pump to help provide long-lasting comfort. All three tiers of heat pumps go through months of extreme testing.
CB: Are there any important installation points that should be mentioned relative to the new heat pumps?
JL: It’s critical to make sure that the contractor is aware of a few changes that may be required. The first one is around the electrical needs. So, if the heat pump needs backup, electric resistance, heat, as is often the case when you switch to a heat pump, there could be an added expense to get high voltage electrical service where you used to have a furnace and just a coil, it didn’t require high voltage. But with the electric resistance heat, you need this high voltage, 208/240 volt.
Additionally, the electrical infrastructure capacity that was feeding the old air conditioner may not even be large enough to support the all electric product, even if you’re staying with the same tonnage. The reason being the electric load on the circuit in the winter may be significantly higher than it was in summer, depending on the climate.
At this time, training is focusing on the breaker size and larger wire runs. The other area is in airflow. A heat pump supplies air at about 100F whereas a furnace delivers it at about 120F. So that means the heat pump is doing a 30 degree rise, and the furnace is doing a 50 degree rise. Well, in order to get the same amount of delivered heating capacity, you’re going to need more airflow on your heat pump. So, you could basically take that ratio of 50 divided by 30, and that’s about two thirds more airflow. If you were running a thousand CFM for your airflow, the new system’s going to need to run 1500 to 1600 CFM. The question is, can the existing duct work support that added airflow?
And if you already had extremely resistive ducts, it’s going to take a lot of external static pressure to move that much air, and it may not support it, in which case, a duct system modification may be required.
I have heard of contractors adding one or two more returns to lower the external static pressure. So that’s another concern.
Third, which I don’t think is as big a deal, is the charging of the refrigerant itself. It is more difficult to charge a heat pump accurately during winter. Our recommendation today is that the installing technician return to the home and run a check charge diagnostic in the spring, when it’s operating under cooling conditions to help ensure that the proper amount of refrigerant is in the system. But the good news is our heat pumps have Trane Link Connectivity, which provides a test mode that includes auto charging. It’s called SmartCharge™. It can tell you very quickly if you’re in good shape, and you can check remotely, so you don’t even have to drive out there. That’s the game-changing thing with Link Connectivity: you can run these test modes, get the green light quickly, and then you’re good to go.
CB: Will heat pump service training be much different than today?
JL: Service training for our future cold climate heat pump will really be no different than it is with today’s variable speed XV20 training, which is available now as an e-learning course, or through one of the FSRs. As we continue to innovate and launch new technologies in the future, we will make slight tweaks to the training to make sure that the contractors know the issues that are specific to that particular unit.
CB: Will Trane heat pumps be in good supply for 2025?
JL: We have many people who are watching product supply and demand, and I would say we’re extremely hopeful that we are going to be ready to meet the needs of all our customers. Because heat pump adoption and enthusiasm are increasing, particularly as we improve this technology, we are prepared to handle all that.

Modern supermarkets are evolving. Refrigeration technicians must balance their application of advanced technologies with foundational skills. by Brett Wetzel
In today’s ever-evolving supermarket landscape, advancements in refrigeration technology and energy efficiency have led to more sophisticated and environmentally friendly systems. However, while the control capabilities of these modern systems have become more complex, the core principles of refrigeration remain unchanged. Effective diagnostics still hinge on a deep understanding of

methodical troubleshooting remains as critical as ever.
Modern supermarkets are constantly evolving, with advancements in greener technologies and energy efficiency being made daily. These innovations bring enhanced control capabilities but also add complexity to refrigeration systems. However, it’s important to remember that, despite this added complexity, the
fundamentals of refrigeration remain unchanged. Diagnosing these advanced systems still relies on a solid understanding of basic refrigeration theory and physics.
A technician’s arsenal of tools hasn’t fundamentally changed over the years. What has evolved is the precision and accuracy these tools now provide, making diagnostics faster and more reliable. Additionally, many modern tools and apps give technicians access to vast libraries of refrigeration formulas and theoretical resources, greatly assisting in diagnosing issues with a higher level of accuracy.
Despite advancements in tools and technology, each situation still requires a case-by-case assessment. Effective diagnosis relies heavily on deductive reasoning and logical analysis. Technicians must make educated assumptions about where to start their investigation—whether the issue lies within a specific case or if it’s a broader system malfunction. This approach is similar to the Socratic method, where thoughtful questioning and analysis guide the problem-solving process.
Each technician has their own procedure for diagnosing issues, but when I start, I start at the mechanical room. This is where I will be able to locate the energy management controller, where you should be able to monitor the pressures, temperatures and other alarms that might have led to the alarm.
Remember these systems have detailed refrigeration schedules, and installation operation manuals that will tell you where the pressures temperature, and amperages should be running around the stem will be normally
Each technician may have their own preferred procedure for diagnosing issues, but my approach always begins in the mechanical room. This area houses the energy management controller, where I can monitor critical data such as pressures, temperatures, and alarms leading up to the fault. It’s essential to utilize the detailed refrigeration schedules and installation operation manuals that these systems provide. These resources specify the expected pressures, temperatures, and amperages, helping you understand where the system should normally be running. The other nice thing about checking the history in the controls systems, typically
you can deduce issues and correlate some issues where you can see some cause and effect… Example : if you see the temperature drop throughout the night thus holding more liquid in the condenser , seeing the receiver level drop then seeing the cases running higher temp because of lack of liquid going to cases. Where in the past we did not have controls to monitor all these temps, pressures, and levels unless you were there you would have no idea why the temperatures started to increase in the refrigerated case.
As an experienced technician I can utilize trends in the graphs to come up with a logical cause and effect within conjunction with using standard refrigeration theory
It’s important to remember that case defrost specifications are based on optimal operating conditions.
Once I know everything is in order with the mechanical room checking pressures, temperatures, and checking for proper liquid level, and temperature. I know, the issue is probably an issue with the case line up.
I utilize ABC method when looking at a case line up, I can get all the data needed from the installation and operation manual needed for this method from the manufacture
The ABC’s of HVAC-R stands for “Air Before Charge”. Whether it’s (CFM) Cubic Feet per Minute or (FPM) Feet Per Minute, check your airflow first. The reason for this is because too much air or too little air will make the next thing that we look at too low or too high, which is the SST or Suction Saturated Temperature. This is done by taking a pressure sample at the outlet of the evaporator and knowing what refrigerant we are utilizing thus being able to convert that pressure into a temperature.
This SST needs to be at spec or within 3 degrees lower than what the spec is called for, example if the case spec is 20°F we can be at 20-17°F SST any lower than that we really start not affect the sizing of our coil and Expansion device.
The last measurement that we should check is superheat, this is only after verifying the other two measurements that we
have just done. This is done by checking the SST and then Subtracting the Suction line temp near where your TXV bulb placement is, Example if the SST was 20°F and the suction line temperature was 28°F the Superheat is 8°F. most spec for medium temp cases is 6-8°F of superheat.
If a refrigeration case meets all manufacturer specifications, it should initially be capable of achieving and maintaining the desired temperatures without issue. However, there can be other contributing factors, such as ambient conditions, that impact case performance. It’s important to remember that case defrost specifications are based on optimal operating conditions. For instance, if the ambient temperature rises above 75°F or the relative humidity exceeds 55%, cases may frost over before the next scheduled defrost cycle.
Modern refrigeration systems have become increasingly complex with the integration of electronic controllers. These controllers manage critical parameters such as Suction Saturated Temperature (SST), superheat, discharge air temperature, defrost duration, defrost termination, and even fan speed—all of which are now regulated digitally. As a result, technicians must not only measure these variables but also ensure the sensors providing this data are accurate. This additional layer of complexity requires a meticulous approach to verify both the performance of the equipment and the accuracy of the monitoring devices.
In conclusion Diagnosing and maintaining advanced supermarket refrigeration systems requires a balanced approach that combines foundational refrigeration knowledge with the ability to navigate sophisticated control technologies. By understanding the fundamentals and applying logical reasoning, technicians can effectively troubleshoot issues and ensure optimal system performance, even in the face of evolving technological advancements.

‘Barring another event causing an economic downturn, 2025 should be a boom year for the HVAC industry, and contractors who prepare for the growth will be big winners.’
It feels like after November 5th our country—and our industry—let out a collective sigh of relief.
Regardless of your political leanings, the uncertainty leading up to one of the most contentious elections in US history in many ways froze everything as we waited to see the direction our country would go.
Most homeowners were caught up in these uncertain times, many putting off major purchases until they get a handle on what the financial future of their families might look like.
This paralyzing state was also felt by many HVAC contractors I’ve spoken to across the country. The feedback has generally been that sales were just OK, or down, as many homeowners have been putting off major investments including replacing their HVAC systems.
I think we will see a resurgence in discretionary spending as the country gets back to “normal.” The surging financial markets are contributing to a more positive outlook as we look to inflation dropping along with gas, grocery, and materials prices.
A more positive environment towards fossil fuel production should also lower transportation costs that heavily impact the cost of goods in virtually all sectors of our economy.
The promise of decreased regulations and lower taxes should also reduce the stranglehold on small businesses as we try to survive and thrive in the years ahead.
Another normalizing force in our industry is the standardization and adoption of A2L refrigerants, and more stable availability of new equipment using them. As we journey forward, our technicians will become better trained to handle the A2Ls, and trucks will be equipped to handle the additional cylinders as well. Technicians and installers will also continue to grow their knowledge and experience with inverter-based systems.
Barring an economic downturn, 2025 should be a boom year for the HVAC industry. Contractors who prepare for this growth will be big winners.
Are you ready to grow? If you haven’t given it a lot of thought, it’s not too late to start looking at where your company is today. Do you have sufficient staff for significant growth? Do you have financing in place to help you through the peaks and valleys
that come with gearing up for growth? Are your business systems in good shape? How about morale? Do you have a good training and career path program in place?
Generally, the first quarter can be pretty slumpy as people recover from the holidays, and traditionally service and replacement slow down in February and March. That makes it even more important to find creative ways to generate new business leading up to the busy season.
Of course, there are many great ways to generate work during the shoulder seasons. Maintenance Agreements are a huge business builder. Performance testing on your service and maintenance calls can also generate leads for lucrative system upgrades and renovations.
