Making Stuff Real - Short #254

HVAC School - For Techs, By Techs ·

2025/08/26

In this short podcast episode about a bigger-picture topic, Bryan talks about making stuff real. He talks about how to make ideas, businesses, podcasts, and other large projects come to life based on his experiences with HVAC School, Kalos, and several other current and past projects. Understanding yourself and the thing you want to do is the first key to making things real. You need to be able to speak intelligently about a topic (without sounding pretentious); mastery isn't always the goal, but

Is HVAC School Worth It?

HVAC School - For Techs, By Techs ·

2025/08/21

In this comprehensive discussion, Bryan sits down with Brad Cooper, an experienced HVAC instructor from Arkansas, and JD Kelly, a trade school graduate, to tackle one of the most pressing questions in the HVAC industry: Is trade school worth it?

Split-Phase vs. 3-Phase - Short #253

HVAC School - For Techs, By Techs ·

2025/08/19

In this short podcast episode, Bryan breaks down the differences between split-phase and 3-phase power in HVAC systems. Split-phase is a form of single-phase power, and it's common in residential HVAC. Three-phase power is more common in commercial and industrial applications. Single-phase power uses only one of the three phases of power produced by the power company. When there is a neutral and two sides of 120V power, that is split-phase power.

Bi-metal & Magnetic Switches - Short #252

HVAC School - For Techs, By Techs ·

2025/08/12

In this short podcast episode, Bryan covers some basics on bi-metal and magnetic switches. Bi-metal switches are made of two dissimilar metals that are bonded together and are often integrated into motors. When the temperature changes, the metals bend. In an overload circuit, they're designed to bend and open the circuit in an overheat condition. Mercury thermostats also use these; they have a bulb attached to a bi-metallic coil, which causes it to wind or unwind when heated or cooled. Fan limit

Understanding Voltage Drop - Short #251

HVAC School - For Techs, By Techs ·

2025/08/05

In this short podcast episode, Bryan drops some knowledge to help with understanding voltage drop, a few different causes of it, and NEC recommendations. Voltage is electrical potential or "pressure," and voltage drop is the reduction in electrical potential energy. We often think of it happening across conductors (which add resistance), but it also happens across loads (like contactor coils). Voltage drop across loads is usually designed, but voltage drop across conductors is usually undesigned and

HVAC School - For Techs, By Techs ·

2025/07/24

In this episode of the HVAC School podcast, Bryan Orr sits down with Adam and Matt to tackle one of the most misunderstood aspects of HVAC system design: return air systems. The conversation dives deep into the common myths surrounding returns, particularly the widespread belief that adding returns to rooms will automatically improve comfort and air mixing. The hosts explore why returns are often seen as mysterious - sometimes helping when added to a room, sometimes making things worse - and work

Fan of Fans - Short #250

HVAC School - For Techs, By Techs ·

2025/07/22

If you're a fan of fans, this is the podcast for you! In this short podcast episode, Bryan shares how installing ceiling fans can be a smart HVAC design strategy (even though he wasn't a fan of fans!). Ceiling fans break the "don't blow air on people" rule we usually refer to in duct design, but they can solve quite a few basic comfort problems, especially in homes with lower loads than we've historically seen. They're great for creating high-velocity airstreams and mixing air. Low-load homes have

Maintenance Mindset - Short #249

HVAC School - For Techs, By Techs ·

2025/07/15

In this short podcast episode, Bryan explores the maintenance mindset. Maintenance procedures require a different skill set from troubleshooting, especially the customer service mindset and dedication to execution. Good maintenance is important, and it may be "boring" to some techs, but it provides value and is worth doing well. Clients purchase maintenance plans for better reliability and efficiency. Several also enjoy the health benefits of cleaner HVAC systems. The key to maintenance is having a

Crankcase Heaters - Short #248

HVAC School - For Techs, By Techs ·

2025/07/08

In this short podcast episode, Bryan talks about crankcase heaters, including their different types, what they do, and when we need to use them. Crankcase heaters usually come in belly band varieties, but some can be inserted into the sump of the compressor. As their name suggests, crankcase heaters heat the crankcase when the compressor is off. They prevent flooded starts since the heat keeps refrigerant from condensing to a liquid in the compressor when the system isn't running. Long off times,
