Field logic for better HVACR work.
HVAC School - For Techs, By Techs treats HVACR as a craft learned through measurements, mistakes, and shared field logic. Episodes move from casual banter into practical conversations about troubleshooting, heat transfer, commissioning, sales, adding plumbing, and how better techs use data.

HVAC School - For Techs, By Techs is an HVACR education show with the patience to stay in the weeds. It is not trying to make the trade sound glamorous. It is trying to make the work make sense. The show’s strongest episodes turn field problems into repeatable diagnostic thinking, using real measurements, equipment behavior, and technician habits as the raw material. Transformer failures become a lesson in VA ratings, overcurrent, float switches, and add-on controls. Heat-transfer talk becomes a way to decide when equipment is fine and the real issue may be duct distribution, load, humidity, or outdoor conditions beyond design. Data episodes spend time on benchmarking, commissioning, retro commissioning, model numbers, serial numbers, data plates, cloud records, and the difference between a one-time reading and a useful history. That level of detail is the point. HVAC School assumes the listener can handle the trade language and rewards that attention with practical reasoning. The tone is friendly, loose, and occasionally dry, but the teaching is serious. Symposium recordings give the feed a community-table feel, with technicians and educators comparing hard lessons, tools, workflows, and the habits that separate better techs from rushed ones. The business episodes widen the frame without leaving the trade behind. Adding plumbing to an HVAC company, for example, is treated as a leadership and focus problem, not just a revenue idea. Sales discussions appear through the same practical lens: what can be tested, shown, explained, and sustained. The show also reflects a tool-aware trade culture, with attention to gauges, recovery machines, dehumidifiers, diagnostic apps, and field documentation. It can be sponsor-heavy in places, and some episodes carry live-event audio imperfections, but the useful material is rooted in the same premise throughout. Good HVAC work depends on disciplined observation. Better decisions come from knowing what the numbers mean. The show serves people who want fewer guesses, cleaner troubleshooting, and a sharper feel for how HVACR systems actually behave.
Made for: This show is for HVACR technicians and trade-minded listeners who want practical trade education with real diagnostic detail. It also fits newer techs who are ready for shop-talk pacing and industry shorthand.
What sets it apart: The show stands out by making field measurements and technician judgment the center of the conversation. It connects diagnostics, tools, business choices, and hard lessons without turning them into generic contractor advice.

A second trade looks attractive until the shop has to carry it.
Adding plumbing to an HVAC business sounds simple at first, but Nate Agentes makes clear how quickly the move becomes a test of the whole shop.
A practical 24-volt fault-finding session for techs who are done guessing at control failures.
HVAC School keeps the focus squarely on 24-volt troubleshooting, with Brian Orr and Johnny Hall stressing isolation diagnosis, blown fuses, and the discipline of tracing the circuit before any parts get swapped.
Heat-transfer basics become a clear diagnostic path for technicians checking why cooling equipment is not keeping up.
Heat transfer gets a practical, jobsite-minded treatment in this short HVAC School episode. Joey Henderson, also known as Jojo, the HVAC man, keeps the focus on a simple balance: heat entering a space versus heat leaving it.
A field-minded case for judging HVAC systems against design intent.
The episode makes a useful case that HVAC performance work should go beyond capturing familiar readings and move toward commissioning equipment against its intended design.
A practical case for turning HVAC measurements into a reusable operating record.
HVAC School's symposium conversation frames field data as an operating record technicians can actually reuse, not just a set of readings for the job in front of them.
A grounded 24-volt HVAC troubleshooting discussion focused on isolation, added loads, and repeat transformer trouble.
The episode turns a blown low-voltage fuse into a real troubleshooting process, not a quick label for every 24-volt problem. Brian Orr and Johnny Hall keep the focus on isolation: find the circuit that is taking out the fuse, then look closely at added controls and loads before…
