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.

This podcast episode is of Bryan’s session from the HVAC School Symposium, “10 Things I’ve Learned in the Last 10 Years.” Delivered as HVAC School approaches its 10-year milestone and Kalos hits 20 years, Bryan blends technical know-how with personal stories, revealing how his “expertise” is a product of constant learning—often from the very audience he’s addressing.

Bryan’s presentation weaves together practical HVAC lessons and relatable anecdotes, offering a glimpse into his growth as a technician, educator, and leader. He tackles wire sizing versus breaker sizing, debunking outdated myths tied to the National Electrical Code and sharing tales of sparring with inspectors over code-compliant innovations. On vent sweating and duct leakage, he provides actionable fixes—like sealing boots and tackling attic moisture—while urging techs to look beyond bandaids. Bryan also dives into coil corrosion, distinguishing formicary from galvanic causes and advocating for field-driven research over manufacturer spin. His interactive style shines as he pauses for audience questions, fostering a dynamic exchange where attendees refine his insights.

The talk balances technical depth with human wisdom, spotlighting patience, joy, and consistency as cornerstones of his journey. Bryan recounts Eureka moments—like unraveling why high-latent markets defy evaporator temperature expectations—and credits mentors like Jim Bergmann and peers like Jordan Cummings for sharpening his perspective. He wraps up with a personal touch, addressing work-life balance as a father of 10 and business owner, advocating for mutual sacrifice with family over unilateral trade-offs.
