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 episode, Bryan leads a live team meeting focused on getting technicians mentally and practically ready for the summer rush. He opens by asking the group to name what makes the season different, and the answers pile up quickly: higher call volumes, hotter attics, more irritable customers, and a nagging pressure to move faster than usual. Bryan distills these observations into a central theme that runs through the entire conversation — the tension between speed and thoroughness, and how the desire to rush during the busy season is the root cause of most costly mistakes and callbacks.

A major thread of the discussion is the idea of “sharpening your ax” before the season’s workload hits full force. Bryan pushes the team to build real confidence in their tools rather than assuming they work correctly. He walks through practical habits: verifying that a leak detector is properly calibrated, understanding its components well enough to troubleshoot it, and periodically checking a vacuum pump with a micron gauge so a technician instinctively knows what normal performance looks like. He also shares a story about a mentor named Howard Erskine, using it to illustrate how small, deliberate routines — from hose-rolling technique to truck organization — compound into real speed without sacrificing accuracy.

The conversation then turns to drain lines and diagnostic philosophy, centered on Bryan’s “wide, narrow, wide” framework. He explains that rushing tends to collapse a technician’s focus into the narrow middle step — fixing only the immediate complaint — while skipping the wide assessment before and after the repair that catches secondary issues like sagging platforms, damaged insulation, or drainage problems before they become bigger failures. A detailed real-world example involving an oversized system in a heavily shaded, lakeside home shows how factors outside a standard load calculation, like mature trees and humidity, can explain why equipment isn’t “keeping up” even when nothing is actually broken.

Bryan closes by connecting these technical habits to business outcomes, urging technicians to fully document and resolve issues rather than telling clients to “keep an eye on it.” He frames average ticket size, callback rate, and time on call as honest indicators of thoroughness rather than sales pressure, and encourages the team to lean into detailed measureQuick reports, thermal imaging, and clear client communication so that no problem gets punted down the road. He wraps up with an honest, encouraging note about the grind of the summer season, reminding the crew that the long hours are temporary and that consistent, unhurried practices are what ultimately make the season more profitable and less stressful.
