Learning Better - Short #246

HVAC School - For Techs, By Techs ·

2025/06/24

In this short podcast episode, Bryan talks about learning styles and gives some tips for "learning better" and getting more out of continuing education opportunities. The first step to getting more out of educational opportunities is to know your learning style. There are three main styles: visual, kinesthetic (hands-on), and auditory. Most tradespeople will probably fall into the kinesthetic category, but not everybody is; you need to figure out if you're most comfortable working with your hands,

TXV Troubleshooting - Short #245

HVAC School - For Techs, By Techs ·

2025/06/17

In this short podcast episode, Bryan walks through some common thermostatic expansion valve (TXV) troubleshooting scenarios. Many of the same principles apply to troubleshooting electronic expansion valves (EEVs). These dynamic metering devices maintain a constant superheat. Troubleshooting does NOT start and end with the TXV. First, you need to inspect components (especially filters, ductwork, and filter-driers) and confirm the airflow and charge. You can use measureQuick to monitor superheat,

2025/06/10

In this short podcast episode, Bryan talks about band-aids, hacks, and ethics. He explores ethical "band-aid" solutions and how to charge for them. He also covers the difference between patching up equipment ethically and unethical repairs. Temporary fixes and ugly permanent fixes fall into the ethical gray area for a lot of people, especially if technicians or HVAC business managers don't know where to draw the line between replacing a part completely and patching up issues.

2025/06/03

In this short podcast episode, Bryan talks about some no-serve situations he's encountered as a technician and HVAC business owner. He also talks about situations that may be unpleasant but aren't quite no-serve situations. Some common and obvious no-serve situations are when a client threatens a technician, especially with lawsuits, bad reviews, or even bodily harm.

HVAC School - For Techs, By Techs ·

2025/05/29

In this informative HVAC podcast episode, Bryan and Bert dive deep into the complex world of locked and internal overload compressors, focusing specifically on single-phase residential units. The discussion begins with Bert explaining one of the most common challenges technicians face: diagnosing a locked compressor. He describes how compressors that are locked will typically run for only a second before overheating and stopping, creating a cycle that can be difficult to detect if technicians aren't

When 0V Isn't Safe - Short #242

HVAC School - For Techs, By Techs ·

2025/05/27

In this short podcast episode, Bryan covers some unique electrical cases: when 0v isn't safe. When you measure voltage, you're finding out the electrical potential between two points. Just because there is 0v between one point and another doesn't mean there will be 0v between those points and other points. Non-contact voltage detectors are good tools that measure the flux from the wiring, but they have their limitations. A common mistake is measuring voltage across a switch. When you measure 0v

Compressor Ohm Mistakes w/ Bert

HVAC School - For Techs, By Techs ·

2025/05/22

In this episode, Bryan and Bert dive into the often misunderstood world of compressor testing, focusing on common mistakes technicians make when using ohmmeters, compressor testers, and megohm meters. The conversation highlights how diagnostic errors can lead to unnecessarily condemned compressors and wasted time and resources. The hosts begin by discussing fundamental concepts like the difference between "open" and "short" conditions, emphasizing that a path doesn't necessarily indicate a short

Motor Ambient Rating - Short #241

HVAC School - For Techs, By Techs ·

2025/05/20

In this short podcast episode, Bryan talks about what the ambient rating means on a motor. These ratings can be found on both condensing fan motors and blower motors. They have Cs in their rating, which represents the maximum ambient temperature the motor can handle in degrees Celsius (like 40C or 60C). Heat and overvoltage kill motors, and motors with higher ratings can withstand higher temperatures and last longer in hot conditions. Be careful not to confuse this rating with the insulation class

Bryan from HVAC School interviews JD Kelly, known as "student of HVAC" on Instagram, about Delta T measurements in HVAC systems. This episode dives into the fundamentals of Delta T, common misconceptions, and proper measurement techniques. JD explains that Delta T is simply a temperature difference between two points of the same medium, which is often misunderstood in the industry. Many technicians are taught to measure between return grills and supply registers, but this approach can lead to

Fire Sprinklers - Short #239

HVAC School - For Techs, By Techs ·

2025/05/06

In this short podcast episode, Bryan talks about fire sprinklers and how to avoid setting them off on job sites. Fire sprinklers have an element in the center that expands when exposed to heat (like a TXV sensing bulb) and breaks the glass. When the glass breaks, the fire sprinkler starts pouring out water. In some cases, fire sprinklers are linked to a larger fire suppression system in which several may go off at once, but most of the time, only a single fire sprinkler will go off if bumped or

Nylog, Oil? Where does it go? - Short #238

HVAC School - For Techs, By Techs ·

2025/04/29

In this short podcast, Bryan answers a listener-submitted question about Nylog, oil, and where you put them when you're making flares. Nylog is a thickened refrigerant oil (which is either POE for Nylog Blue or mineral oil for Nylog Red), and it's miscible with the refrigerant and moves with it through the circuit. You don't want to put excess Nylog on valves, but a small amount won't do harm. There are a lot of concerns about Nylog voiding the warranty, but it doesn't actually do that because it's
