Overtime is also almost unavoidable in many places, and it's a problem that requires a more n...
Refrigerant Myth Busting w/ Dr. Chuck
December 15, 2022 12:00 - 38 minutes - 52.6 MBDr. Chuck Allgood from Chemours returns to the podcast to do some refrigerant myth-busting. Many people don’t understand why high-GWP HFCs can impact the atmosphere if the refrigerant is heavier than air. High-GWP HFCs exist for a long time, and they last long enough for natural mixing and the wind to distribute their molecules throughout the atmosphere. HFOs, by comparison, are more reactive in the atmosphere and have relatively short lifespans, meaning they have less of an effect on the ...
The Good, Bad and Ugly of Trade Schools
December 13, 2022 12:00 - 45 minutes - 63.3 MBTy Branaman and Eric Kaiser return to the podcast to discuss the good, the bad, and the ugly of trade schools. They cover the opportunities and challenges they've observed in trade schools.

Inductive Current Myths - Short #158
November 22, 2022 12:00 - 9 minutes - 12.9 MBIn this short podcast in our electrical myths series, Bryan talks about some inductive current myths. There is a common myth surrounding voltage drop in inductive loads. When you decrease the voltage in a circuit with a resistive load, you'll see a relatively proportional drop in resistance (ohms) and current in accordance with Ohm's law. So, we'll see a decrease in current, but we have to keep in mind that load temperatures also affect the resistance (and the current, by extension). Som...
Why it REALLY gets hot upstairs w/ Alex Meaney
November 17, 2022 12:00 - 49 minutes - 68.8 MBAlex Meaney returns to the podcast to explain why it REALLY gets hot upstairs and what we can do about it. He also talks a bit about his new business. Heat technically doesn’t rise; warm air is less dense than cooler air, so cooler air sinks as warmer air rises. In many cases, people blame stratification and the stack effect for warm upstairs areas, but there may actually be other issues at play, especially if the issue only seems to happen in the summer. Many apparent convective proble...
Electrical Myths - Single phase is Really 2-Phase - Short #157
November 15, 2022 12:00 - 9 minutes - 12.7 MBIn this short podcast, Bryan busts the common electrical myth that single-phase 240v power is really two-phase power. When power goes into a structure that runs 240v appliances, we may understand that two 120v sine waves are 180 degrees out of phase with each other, but that isn’t 100% accurate. If we were to use an oscilloscope to watch the electrical sine waves, we would see two sine waves 180 degrees out of phase because the transformers are center-tapped. Center-tapping creates a neutr...

Electrical Myths - Hard Starts Reduce Start Current - Short #156
November 08, 2022 11:00 - 15 minutes - 21.8 MBIn this short podcast, Bryan busts the myth that hard starts reduce the start current on the run winding of a compressor. A single-phase motor’s main winding is the run winding; it has a lower resistance and a higher current than the auxiliary winding, also known as the start winding. Hard start kits are often used on HVAC systems with single-phase compressors (which usually have PSC motors). These kits usually consist of a start capacitor and a potential relay, which takes the start ca...
The 24-Hour Technician w/ Andy Holt
November 03, 2022 15:04 - 40 minutes - 56.3 MBAndy Holt joins the podcast to talk about what it means to be a 24-Hour Technician. We talk about what it means to be HVAC/R technicians AND deal with the human aspects of our lives at the same time. Service technicians differ from installers in that they do much of their work solitarily. They spend a lot of time by themselves. They’re also on their feet very often and may do emotionally exhausting work, but they can earn a respectable living and accumulate savings for the future. To make ...
