Tech Tips:

The Case for Checking the Charge Without Using Gauges

Jim Bergmann and I recorded a podcast for HVAC School that covered when and how to check the refrigerant circuit without connecting gauges. Listener Joe Reinhard listened several times and wrote up this summary of what he gained from the episode. I edited it lightly, but most of this is his work. Thank you so […]

Full System Diagnosis – There is More to Check

In this episode, Bryan goes back over the basics and stresses the importance of diagnosing the whole system. I’ll cut to the chase: inspection is NOT overrated. Inspections help you become more familiar with HVAC systems and can help you catch on to minor issues before they spiral out of control. Check air filters, check […]

Refrigeration Tips For A/C Techs

In this episode of the HVAC School Podcast, Bryan talks with Jeremy Smith about refrigeration tips, terms and processes. They also cover the similarities and differences between A/C and refrigeration. Being on-call as an A/C tech is not all that different from being on-call as a refrigeration tech. Similarly, the principles of heat transfer don’t […]

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 Orr sits down with Ty Branaman for a wide-ranging conversation about what it really takes to be a good on-call technician. They open by reminiscing about how dispatch technology has evolved over their careers — from pagers, radio codes, and outdated paper map books to MapQuest, early GPS units, and today’s 24-hour dispatch systems. That trip down memory lane sets up the episode’s central theme: while the tools have changed, the mindset needed to succeed on call has not. Both hosts agree that being on call can be genuinely enjoyable when a technician learns to embrace the autonomy, the bigger paychecks, and the quieter, less stressful roads that come with nights and weekends.

A major thread running through the discussion is self-discipline and long-term thinking. Bryan and Ty encourage younger techs to treat on-call money as an opportunity rather than spending cash — saving and investing overtime pay instead of financing trucks, boats, or other lifestyle upgrades. They share stories about the financial traps of seasonal trade work, the value of staying in a consistent routine even at 2 a.m., and how cutting corners under fatigue is often what leads to injuries or callbacks. Ty compares a disciplined on-call tech to a pilot running through a pre-flight checklist: the process matters just as much in the middle of the night as it does at noon.

The conversation also digs into customer relationships and judgment calls in the field. They talk candidly about the difference between genuine emergencies and entitled or overblown complaints, and how companies that over-market “24/7 service” can create unrealistic customer expectations. Bryan shares a story about temporarily misting a struggling condenser to get an elderly client through a brutal heat wave, using it to illustrate the kind of judgment-based, get-them-by fix that defines old-school on-call work — as opposed to always pushing for a full sale. Safety boundaries, cutting corners responsibly, and the excitement of solving unpredictable problems on the fly are all discussed as part of what makes the work rewarding despite its challenges.

Finally, Bryan and Ty turn to advice for company owners and service managers. They emphasize building fair, well-communicated on-call rotations, respecting technicians’ personal time, and charging appropriately for after-hours work so that both customers and technicians value it. Ty argues that the industry needs to reframe HVAC work as a skilled trade rather than commodity labor, and that companies should be careful not to chase more emergency calls than their technician pool can sustainably handle. The episode closes with reflections on career growth, mentorship, and the kindness that comes from helping teammates cover on-call shifts for one another.
