In this action-packed live stream episode of HVAC School, host Bryan is joined by Eric Kaiser, Ty Branaman, and Roman Baugh for a continuation of a deep-dive conversation on vacuum practices — picking up where a previous episode left off with Andrew Greaves and Jim Bergmann. The team sets out to both reinforce the foundational best practices every HVAC technician should follow and to explore some genuinely uncharted scientific territory around how vacuum gauges actually work, how refrigerant contaminates micron gauge readings, and what really happens to moisture inside a system when...

This short podcast is from the Bry-X stage of the 7th Annual HVACR Training Symposium: Cheryl Klein's "Surge Protection for HVAC." Cheryl is with DITEK, a veteran-owned company based in Florida, and has extensive knowledge of whole-home surge protection and HVAC-specific surge protectors. HVAC systems may have their lifespans reduced by power surges (tens of thousands of volts within microseconds) or sustained overvoltage. Surge protectors specifically protect the equipment from power surges, though DITEK manufactures products that help manage sustained overvoltage (and undervoltage, which...

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...

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...

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...

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...

Join Joey Henderson LIVE from the 7th Annual HVAC/R Training Symposium in Florida! This essential training breaks down the science of heat transfer into practical field techniques every technician needs. What You'll Learn: Understanding sensible heat (dry bulb) vs latent heat (wet bulb) removal Why airflow matters Heat transfer diagnostics BEFORE pulling out gauges Gas furnace temperature rise troubleshooting How all about heat relates to cooling, heating, and refrigeration Inverter/cold climate heat pump heat transfer principles Target saturated temperatures Key Takeaways: Industry...
info_outlineIn this heartfelt and wide-ranging episode, host Bryan reconnects with Jim Bergmann of measureQuick after nearly three years apart. The reunion is anything but ordinary — Jim opens up about a serious battle with non-Hodgkin's B-cell lymphoma that sent him through not one but two rounds of chemotherapy, ultimately requiring a cutting-edge CAR-T cell immunotherapy treatment at the Cleveland Clinic. Jim shares the remarkable medical journey of having his T cells extracted, genetically modified in a Maryland lab, and reintroduced into his body to permanently attack cancer cells. Now past the critical six-month remission milestone, Jim is back, healthy, and more motivated than ever to push the HVAC diagnostics industry forward.
From his medical comeback, the conversation transitions naturally into what Jim loves most: the world of HVAC diagnostics and the evolution of measureQuick. After years of defending a per-use pricing model that the market simply didn't embrace, Jim candidly admits the old model wasn't working. With the help of business partner Eric Preston (formerly of TruTech Tools), the team overhauled the software's pricing structure in February — a move that has since driven 90%+ customer retention and accelerated growth significantly. The new focus is squarely on "time to value," streamlining workflows so technicians reach key diagnostic reports faster than ever before.
A significant portion of the episode dives into how measureQuick is thoughtfully integrating artificial intelligence. Rather than chasing AI trends, Jim and his team — including AI specialist Ben Reed — took a deliberate approach: identifying the precise areas where AI genuinely helps technicians without creating distractions. The standout use case is label identification, where AI reads equipment labels and auto-populates system profiles. Jim is refreshingly candid about AI's limitations in HVAC diagnostics, explaining that the field variability of real-world systems (varying line set lengths, mismatched equipment, non-standard airflow conditions) makes purely AI-driven diagnostics unreliable. Instead, measureQuick leans on first-principle modeling and non-dimensional mathematics to generate objective, data-driven results.
The episode closes with a thought-provoking discussion about the state of the HVAC industry at large. Bryan and Jim tackle the growing influence of private equity consolidation, the persistent problem of technicians skipping probe deployment, the difference between clearing faults and actually fixing them, and the importance of commissioning and retro-commissioning equipment to manufacturer design intent. Throughout it all, the conversation is anchored by a shared belief: that measuring everything — in business and on the job — is the foundation of genuine, lasting improvement. It's a must-listen for any HVAC professional or business owner who wants to understand where the industry is headed.
