    20 Years in Family Business from the Kalos Founders

    In this special live panel session recorded at the 7th Annual HVAC/R Training Symposium, the three founders of Kalos Services — Bryan Orr, his father Robert (Bob) Orr, and uncle Keith Huntington — sit down together to celebrate the company's 20th anniversary and answer questions from the audience and online attendees. Hosted by Bert, the conversation blends humor, hard-earned wisdom, and surprising candor about what it actually takes to build and sustain a trades business over two decades. From humble beginnings with $100,000 in startup capital to managing multi-million-dollar commercial contracts today, the founders pull back the curtain on the messy, unpredictable, and deeply human reality of entrepreneurship in the skilled trades. A recurring theme throughout the panel is that starting a business requires far more than technical skill — it demands grit, personal support, and an almost stubborn refusal to outspend your income. Bryan shares a raw, memorable story about living in a double-wide trailer with seven kids while Kalos was already nine years old, choosing to improvise a drainage workaround rather than take on debt he couldn't afford. The founders agree that the number-one ingredient for small business survival is grit — the ability to wake up the next morning after a terrible day and take the next step anyway. Robert adds a philosophical note that extreme negative emotions in business are almost never accurate; they pass, and tomorrow tends to look better than the night before suggested it would. One of the most discussed topics in the panel is how to motivate technicians to care about quality — not just revenue targets. Bryan makes a pointed distinction: if you build a compensation system optimized purely for money, you attract people who are only motivated by money. Instead, he advocates building a culture where belonging is tied to quality of work. Practical tools like daily photo-posting of installs in Google Chat, public shout-outs for great work, and peer commentary create an environment where craftspeople hold each other to a standard — not because they're forced to, but because it's who they are. Keith echoes this, emphasizing that most technician frustration stems not from laziness but from unclear systems and expectations set by leadership. When people don't know what's expected, they disengage — and that's a leadership problem, not a people problem. The panel also dives into the nuances of running a family business, with all three founders offering surprisingly candid takes. Keith notes that the key to 20 relatively friction-free years has been that all three founders are "120 degrees different" from each other — their strengths don't overlap, so they rarely fight over territory. Bryan adds that healthy family businesses require the ability to have real conflict for the sake of mission, not just harmony. He also speaks to the importance of organizational structure when family members are involved: his own son Gavin, at 21 years old, works at Kalos but reports through multiple layers of management precisely so Bryan doesn't micromanage him. The session closes with reflections on the riskiest moments in the company's history — and Bryan's honest admission that four weeks prior to the symposium ranked among the most stressful, as large promised contracts delayed in paperwork can shake even an established business to its core. Topics Covered Expanding HVAC services into electrical and plumbing — what technicians can realistically do and when to partner with specialists The real prerequisites for going out on your own: craft knowledge, personal support system, and financial discipline Why grit — not capital or credentials — is the single most important ingredient for small business survival How to attract technicians who genuinely care about quality, not just technicians who chase commissions Using internal tools like Google Chat to reinforce a culture of craftsmanship and peer accountability The danger of building systems that look great on paper but don't survive contact with real-world field conditions Advice on contractor mentoring programs — how to absorb outside coaching without losing your own identity and standards Lessons from running a family business: complementary roles, honest conflict, and the importance of organizational separation How Kalos Services grew from $100,000 in startup capital to a multi-trade general contractor over 20 years The role of visionary vs. operator personalities in a founding team, and why both are essential The founders' biggest career mistakes — including owning full responsibility for a six-figure grocery store power outage Why private equity growth models don't translate to owner-operated trades businesses Hiring to fill your weaknesses: from permitting to office management, delegating what you hate frees you to lead Recommended training resources: HVAC School, Ty Craig / Skill Cat, Ruth King, ESCO, and Dirk Nauman Why the riskiest stage of business is never behind you — it scales with the size of your contracts   Have a question that you want us to answer on the podcast?

    Permanent Load Reduction As a Sales Driver - Short #284

    This short podcast episode is Jeremy Begley's Bry-X session from the 7th Annual HVACR Training Symposium: "Permanent Load Reduction in HVAC – The Hidden Driver of Long-Term Sales."  Some common customer complaints we hear as HVAC contractors include high humidity, high electric bills, noise, and uncomfortable rooms. The typical HVAC solution is to change the equipment or ductwork, such as by downsizing the unit, adding ancillary dehumidification, or modifying the ductwork. If we can't solve the problem, the customer will ultimately choose a different contractor, no matter how hard we try to modify the HVAC system. However, we may be able to use our thorough load calculations to turn our attention to the building and find ways to reduce the overall loads. We expose problems with the structure and can solve them with permanent load reduction strategies, rather than the equipment and ductwork modifications, and serve customers better while earning more money. Key performance indicators (KPIs) drive money in a business, and ServiceTitan has identified five KPIs closely linked to profit: callbacks, first-time fix rate, warranty claims, comfort complaints, and average ticket. Callbacks are often driven by comfort complaints, which may occur when we modify equipment but not the envelope and vice versa. Warranty claims occur when the equipment can't work as well or efficiently as intended, such as when the load doesn't match the equipment and strains the unit. When we solve these problems, we become trusted advisors and increase customer satisfaction. The customer will continue to work with a company that solves their problems and will recommend HVAC businesses to their family and friends, which also drives sales.  Permanent load reduction requires us to understand load calculations thoroughly, but it's a means for HVAC companies to control outcomes. It requires a mindset change, but when we control system outcomes and increase customer satisfaction, we earn trust and earn more sales in return.   Have a question that you want us to answer on the podcast?

    Cold Climate Evacuation Livestream - Pandora's Box

    In this long-awaited live episode of HVAC School, host Bryan Orr reunites with three industry veterans — Jim Bergmann of measureQuick, Roman Baugh (Kalos), and Andrew Greaves of NAVAC — to tackle one of the most pressing and underaddressed challenges in modern HVAC: performing refrigerant recovery and system evacuation in extreme cold-weather conditions. The conversation was sparked by a real-world observation from technician Chris Hughes, who relocated from Louisiana to Minnesota and quickly discovered just how different — and difficult — cold-climate HVAC work can be. What follows is an honest, science-heavy, and often humorous deep dive into a problem the industry has largely ignored. The episode centers on the growing prevalence of cold-climate heat pumps, especially inverter-driven systems capable of operating at extremely low outdoor temperatures. As these systems become the primary heating source in cold regions, technicians are increasingly being called to make repairs — and perform evacuations — in sub-zero conditions. The group walks through why this is such a challenge, examining the fundamental physics that make pulling a proper vacuum nearly impossible once temperatures drop below 40°F. The conversation draws heavily from refrigeration science principles that, as Jim Bergmann bluntly points out, were largely left out of HVAC trade education over the past several decades. One of the most compelling moments of the episode is Andrew Greaves' introduction of the "heat provocation test," a term he coins on the spot to describe a technique for verifying whether moisture has truly been removed from a system by observing micron gauge behavior after applying external heat to cold-soaked components. This sparks a rich debate between Jim and Andrew about where moisture actually concentrates in a system — in the line set vs. the outdoor unit — and whether heat can realistically reach those areas in a real-world installation. The panel ultimately agrees that heat is the only viable tool when you absolutely must complete a job in cold conditions, but that prevention and scheduling remain the gold standard. The episode closes with a fascinating dive into the phase diagram of water, specifically the concept of the "triple point" and how it governs moisture behavior at low pressures. Andrew uses a whiteboard diagram to explain why, below 4,500 microns, moisture can only exist as vapor or solid — not liquid — and why that makes sublimation the only removal pathway when heat is absent. Jim adds nuance by describing the self-refrigerating cycle that occurs during deep vacuum pulls, a phenomenon that makes the problem progressively worse the deeper you pull without adding heat. The group wraps up with practical field takeaways and a promise to revisit the topic, including the potential role of nitrogen purging and triple-evacuation techniques in cold-weather scenarios. Topics Covered The rise of cold-climate heat pumps and why they demand refrigerant work during cold seasons Why evacuation becomes extremely difficult — or impossible — below 40°F ambient temperature The physics of moisture removal: heat energy, vapor pressure, and molecular movement Jim Bergmann's real-world demonstration pulling a vacuum to 135 microns on a wet system and still failing the decay test Andrew Greaves' "heat provocation test" — using external heat sources to verify dryness after evacuation The debate over where moisture concentrates: outdoor unit vs. line set Why mini-split manufacturers don't allow permanent desiccant dryers — and workarounds using temporary bypass configurations VRF systems and how shell dryers can be temporarily added and then removed post-evacuation The self-refrigerating cycle: how pulling a vacuum on ice makes the system progressively colder and more resistant to drying Phase diagram of water: the triple point (~4,580 microns) and why liquid water becomes unstable below it Why sublimation is the only moisture removal pathway below the triple point Gibbs free energy and its role in determining which phase (solid, liquid, vapor) a substance will occupy Hot nitrogen purging as a method for carrying moisture out of open line sets Push-pull recovery technique to maximize refrigerant removal in cold conditions The challenge of vapor recovery in cold weather — leaving multiple pounds of refrigerant behind Practical field solutions: insulated tarps, portable propane heaters, belly band heaters, heat guns Dry ice cold-trap brainstorm as a creative moisture capture method The dual-fuel argument: why Jim advocates for backup heating as the real long-term solution How rapid industry growth in the mid-20th century led to mechanics being trained instead of engineers, losing foundational science in the process Why this topic matters more now than ever as cold-climate compression refrigeration becomes mainstream   You can watch the original livestream on YouTube HERE.

    Training Refrigeration: Building Technicians Who Think, Not Just Fix - Short #283

    Training the refrigeration technician is about building technicians who think, not just fix. In this engaging conversation from the 7th Annual HVAC/R Training Symposium, host Trevor Matthews sits down with Billy Carlson to explore what it really takes to develop technicians who think critically and troubleshoot effectively. Billy shares his journey in the HVAC/R industry, from residential air conditioning to commercial refrigeration, and ultimately specializing in supermarket rack systems and CO2 refrigeration. With only five years in the grocery sector, his company now dedicates 70-80% of its work to refrigeration, with 40% focused on rack systems. This rapid transition offers valuable insights for contractors looking to expand into commercial refrigeration. Key Topics Covered: Building Technicians, Not Just Fixers - Why understanding component flow, P&IDs, and electrical diagrams is crucial for developing thinking technicians rather than parts changers CO2 Refrigeration Training - Billy's honest account of learning CO2 systems, including challenges with dry ice formation, charging procedures, and system tuning Supermarket Rack Work - The unique pressures and rewards of maintaining systems that hold entire stores, including HFC and CO2 racks with multiple compressors Effective Training Methods - Billy's approach to teaching his five-person team, from component identification to reading refrigeration schedules and understanding sequence of operations Fine-Tuning Systems - Insights on slowing down ramp rates, adjusting flash tank pressure, and the importance of proper startup commissioning time Controls & Communications - Why modern refrigeration technicians need to understand networking, gateways, and digital controls alongside traditional refrigeration knowledge Billy emphasizes that patience and willingness to ask for help are essential traits for anyone entering supermarket refrigeration. He shares practical tips on charging CO2 systems, avoiding dry ice in lines, working with VFDs, and reading trend graphs to optimize system performance. Whether you're a residential tech considering commercial refrigeration, a trainer developing curriculum, or a service manager building a team, this conversation offers real-world wisdom on creating technicians who understand the "why" behind every repair.   Check out Refrigeration Mentor at https://refrigerationmentor.com/.   Have a question that you want us to answer on the podcast?

    Succession in Family Business w/ TruTech & Kalos

    In this special collaborative episode between the Building HVAC Science Podcast and HVAC School, host Bryan Orr sits down with his father and co-founder Robert Orr (Kalos) and Bill and Billy Spohn, the father-son duo behind TruTech Tools, for an in-depth conversation about the realities of running, transitioning, and ultimately passing the torch in a family-owned business. What makes this episode particularly compelling is that both pairs are actively living through their own succession journeys in real time, offering listeners an unusually candid and personal look at the emotional, structural, and cultural dimensions of handing off a business you helped build from the ground up. The conversation begins with each participant sharing where they stand today. Bill Spohn Sr. is transitioning into semi-retirement as CEO and co-owner of TruTech Tools, which has tripled in revenue since his son Billy joined the company in 2018. Billy Spohn has stepped into the role of President and co-owner, focusing on working on the business rather than in it. Robert Orr, co-founder of Kalos alongside Bryan, has similarly stepped back after a formalized three-year succession plan, with Bryan now holding majority ownership and day-to-day control. Together, these four men represent two different approaches to the same deeply human challenge: what does it really mean to let go of something you built, and how do you do it in a way that honors both the past and the future? A major theme throughout the episode is the emotional weight of identity and transition that founders and long-time leaders rarely talk about openly. Both Bill Spohn Sr. and Robert Orr reflect candidly on how much of their personal identity has been wrapped up in their respective companies, and how surprising it has been to grapple with the shift from decision-maker to advisor. Robert speaks movingly about health challenges, including having suffered strokes, that accelerated his thinking about succession and mortality. The group explores how no amount of business planning fully prepares you for the emotional reality of stepping back, and yet both men express genuine peace and gratitude for how their transitions have unfolded. The honesty in these reflections is rare and refreshing, especially in business media that often skips the messy human middle. The discussion also digs deeply into the operational and cultural infrastructure that makes a successful handoff possible. TruTech Tools implemented the Entrepreneurial Operating System (EOS) starting in 2022, a framework that Billy says was one of the greatest gifts his father could have given him before assuming leadership. EOS brought role clarity, accountability structures, and regular team rhythms that transformed how the company functions. Bryan and Robert took a more organic approach at Kalos, leaning on trust, a shared value system, and clearly defined responsibilities that evolved over years of working side by side. Both companies emphasize that clarity and accountability are non-negotiable, regardless of company size, and that culture is not a poster on the wall but a reflection of how leaders actually behave when things get hard. The episode closes with practical advice for other family business owners navigating similar journeys. Key takeaways include starting the conversation early, building an advisory board outside the company, making public commitments to accountability, investing in business reading and peer groups, holding regular family meetings so that everyone understands the plan, and above all, prioritizing emotional health and the ability to have hard conversations before they become festering resentments. Bryan offers a memorable point: intelligence gets beaten by emotional regulation and patience every day. The group is unanimous that succession planning is not a single event but a thousand small handoffs, and the best time to start preparing is well before you feel ready. Topics Covered Introductions: Bryan Orr (Kalos), Robert Orr (Kalos co-founder), Bill Spohn Sr. (TruTech Tools CEO), and Billy Spohn (TruTech Tools President) TruTech Tools 3x revenue growth since Billy joined in 2018 The emotional side of letting go: identity shifts, loss of relevance, and the unexpected grief of stepping back from a business you built Moving from decision-maker to advisor: how both Bill Sr. and Robert are navigating this transition Legacy vs. transactional business: building to keep versus building to sell, and the stewardship mindset The baton handoff metaphor: why succession is a thousand small transitions, not one dramatic moment Robert Orr on health challenges (strokes) that accelerated his thinking about succession planning EOS (Entrepreneurial Operating System) at TruTech Tools: what it is, how it was implemented over two years starting in 2022, and why Billy credits it as the single biggest gift for his leadership journey Role clarity and accountability charts versus traditional org charts Quarterly employee check-ins as an alternative to annual reviews How Kalos grew organically without a formal EOS framework, and the value of building structure around trust and shared values GWC framework from EOS: Gets it, Wants it, Capacity to do it Kalos hitting 400+ employees and the challenges that come with scale Culture preservation through succession: how core values survive a leadership change Faith-based principles in business culture: loving your neighbor, leading with grace, clarity as kindness The concept of stewardship: feeling responsible for a business rather than simply owning it Separate job descriptions for CEO vs. President at TruTech Tools and why it mattered for the whole team Bryan on having five family members working at Kalos and maintaining clear boundaries between family and professional roles Advice for family businesses: start early, overcommunicate, make public commitments, seek outside advisors Building a small advisory board outside the company for outside perspective Recommended resources: business peer groups, books on succession planning, and the EOS/Traction framework by Gino Wickman The importance of family meetings for keeping non-active family members informed and aligned Forgiveness and reconciliation as a foundation for healthy family business relationships Having hard conversations proactively so tension does not carry into family life Bill Spohn Sr.'s closing reflection on what comes after stepping back, and the importance of preparing for your next chapter in life Resources mentioned: Traction by Gino Wickman Rocket Fuel by Gino Wickman & Mark Winters Succeeding by Albert Ciuksza Good to Great by Jim Collins Family Business Succession: The Final Test of Greatness by Aronoff, McClure, & Ward Process! by Mike Paton and Lisa Gonzalez The Business Transition Handbook by Laurie R.

    Troubleshooting Tips and Tricks w/ Let's Be Techs

    In this episode of the HVAC School Podcast, host Bryan sits down with Johnny, the creator behind the popular social media channel "Let's Be Techs." Johnny brings a wealth of hands-on experience to the table, having spent his first 13 years in residential HVAC before transitioning into commercial refrigeration. He shares his unconventional path into the trade—starting out building houses before being recommended to an HVAC contractor—and how the lack of quality mentorship early in his career motivated him to create educational content for technicians. His videos, which began as a fun hobby and a way to teach his helper remotely, have since grown exponentially across TikTok, YouTube, and Facebook, and continue to attract technicians hungry for practical, real-world knowledge. The bulk of the episode is a deep dive into real-world troubleshooting strategies, covering everything from the very first moments you arrive on a job site to diagnosing complex intermittent electrical faults. Bryan and Johnny both emphasize the value of using your senses before reaching for specialty tools—listening for surging liquid lines, feeling condenser airflow with your hand, and visually inspecting service valves for oil before removing caps. They share a mutual philosophy that the best technicians are those who can step back, assess the big picture, and narrow down the problem systematically rather than immediately jumping to assumptions about charge levels or component failures. A significant portion of the conversation centers on low-voltage electrical diagnostics, an area where both techs have noticed major changes over the last several years. Bryan and Johnny discuss the rise of contactor coil failures, transformer overload from aftermarket add-ons like UV lights and zone dampers, and the clever use of a contactor in place of a fuse as a low-cost short-finder tool. They also revisit the concept of "tattletale" fuses and resettable fuses, comparing their reliability and appropriate applications. Throughout these discussions, both hosts bring in personal war stories that make the technical content feel grounded and immediately applicable to everyday service calls. The episode wraps up with discussions on thermal imaging cameras, scroll compressor anomalies, and a memorable consulting story from Barbados involving a VRF system. Johnny and Bryan also touch on the importance of sharing knowledge openly in the trades, pushing back against the gatekeeping mentality that leaves newer technicians struggling to find reliable information. Both agree that the comment sections of field-focused videos have become a valuable community resource—a place where techs teach each other, correct each other, and build a collective knowledge base that benefits the whole industry. Topics Covered Johnny's background: from construction to HVAC apprenticeship to commercial refrigeration How "Let's Be Techs" started as a fun hobby and grew into a major social media presence Using your senses first: listening, looking, and feeling before pulling out specialty tools Checking service valves for oil and inspecting caps/seals before connecting gauges Walk-in cooler first-response checklist: fans, thermostat display, suction line frost, liquid line surging Feeling condenser airflow direction to diagnose dirty or clogged coils Identifying capacitor and contactor issues from the moment you approach residential equipment The rise of contactor coil failures and how location-based dirty power contributes Transformer overload: understanding the 40 VA / 24V current rating and why a 5-amp fuse doesn't protect windings Aftermarket add-ons (UV lights, dampers, zone systems) overloading low-voltage circuits Float switches fusing closed from excess current draw The contactor-as-short-finder trick: a DIY alternative to the Short Pro tool Adding individual circuit fuses ("tattletale" fuses) for isolating intermittent low-voltage shorts Resettable (popper) fuses: reliability issues and why 3-amp versions outperform 5-amp versions Contextual diagnostics: thinking about when and why a fuse blew (weather, season, recent activity) The 225°F discharge line rule for monitoring compressor health Scroll compressor oddities: running backwards, check valve failures, and starting under equalized pressure VRF system quirk: electronic expansion valves staying open when power is cut to one air handler Thermal imaging cameras: practical applications in the field including electrical panels, motors, condenser coils, and compressor racks Using black tape (gaffer's tape) to improve thermal imaging accuracy on shiny surfaces Megohmmeter use for finding wire shorts that are intermittent but close to failing The importance of anti-gatekeeping: sharing knowledge freely and learning from community feedback   Follow Johnny on social media as "Let's Be Techs" on YouTube, TikTok, Facebook, and Instagram.
