  • Troubleshooting Tips and Tricks w/ Let's Be Techs

    Troubleshooting Tips and Tricks w/ Let's Be Techs
    Apr 9 2026
    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 refrigerationHow "Let's Be Techs" started as a fun hobby and grew into a major social media presenceUsing your senses first: listening, looking, and feeling before pulling out specialty toolsChecking service valves for oil and inspecting caps/seals before connecting gaugesWalk-in cooler first-response checklist: fans, thermostat display, suction line frost, liquid line surgingFeeling condenser airflow direction to diagnose dirty or clogged coilsIdentifying capacitor and contactor issues from the moment you approach residential equipmentThe rise of contactor coil failures and how location-based dirty power contributesTransformer overload: understanding the 40 VA / 24V current rating and why a 5-amp fuse doesn't protect windingsAftermarket add-ons (UV lights, dampers, zone systems) overloading low-voltage circuitsFloat switches fusing closed from excess current drawThe contactor-as-short-finder trick: a DIY alternative to the Short Pro toolAdding individual circuit fuses ("tattletale" fuses) for isolating intermittent low-voltage shortsResettable (popper) fuses: reliability issues and why 3-amp versions outperform 5-amp versionsContextual diagnostics: thinking about when and why a fuse blew (weather, season, recent activity)The 225°F discharge line rule for monitoring compressor healthScroll compressor oddities: running backwards, check valve failures, and starting under equalized pressureVRF system quirk: electronic expansion valves staying open when power is cut to one air handlerThermal imaging cameras: practical applications in the field including electrical panels, motors, condenser coils, and compressor racksUsing black tape (gaffer's tape) to improve thermal imaging accuracy on shiny surfacesMegohmmeter use for finding wire shorts that are intermittent but close to failingThe 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.
