Tech Tips:

I watched an instructional video the other day where the guy kept palming his gauge manifold and CRANKING down on the valves when he closed them. I've seen techs use channel locks—and even vise grips—to tighten down their gauges “just in case” when they have a hard time finding a leak or a vacuum that […]

Building Tools & the Trade w/ Tony G. from Fieldpiece

Recorded live on the third day of the AHR Expo 2026 in Las Vegas, Nevada, this episode of HVAC School brings together host Bryan and longtime friend of the show Tony Gonzalez, Director of Training at Fieldpiece Instruments. The conversation kicks off with some light-hearted banter about trade show survival tips — including the […]

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In 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.
