Maintenance Mindset - Short #249 show art Maintenance Mindset - Short #249

HVAC School - For Techs, By Techs

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 "do no harm" mindset and a commitment to delivering value. A sales-oriented mindset should take...

HVAC School - For Techs, By Techs

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, long line sets, and cold temperatures all increase a system's risk of flooded starts. Hard shutoff...

Capacitor Testing and Replacement - Short #247 show art Capacitor Testing and Replacement - Short #247

HVAC School - For Techs, By Techs

In this short podcast episode, Bryan goes through the process of testing and replacing a run capacitor.  Run capacitors provide continuous phase-shifted current to the start winding, allowing the motor to run in the right direction and with the appropriate amount of torque. These capacitors are needed in most of the single-phase PSC motors we work with. Run capacitors are in the circuit all the time and are connected in series with the start winding (compared to start capacitors, which need to be taken out of the circuit after startup). They don't actually "boost" voltage. The bigger...

Learning Better - Short #246 show art Learning Better - Short #246

HVAC School - For Techs, By Techs

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, listening to podcasts, watching videos, or reading. It's also a good idea to try the practical...

TXV Troubleshooting - Short #245 show art TXV Troubleshooting - Short #245

HVAC School - For Techs, By Techs

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, subcooling, static pressure, and other key measurements, and the TrueFlow grid can give you a true...

In this episode of the HVAC School podcast, Bryan welcomes back Brynn Cooksey from Air Doctors and HVAC U to discuss critical topics facing the HVAC industry today. Brynn brings his unique perspective as both a successful contractor in southeast Michigan and an industry educator who has made the transition to focusing primarily on workforce development and training.

The conversation begins with a deep dive into indoor air quality (IAQ), where Brynn challenges the common industry approach of throwing products at problems without proper testing. He emphasizes that effective IAQ solutions start with comprehensive testing to identify specific issues like high particles, volatile organic compounds (VOCs), or excessive carbon dioxide levels. Rather than relying on "magic bullet" products, Brynn advocates for a holistic approach that prioritizes ventilation strategies, source control, and proper filtration. He particularly stresses the importance of the "V" in HVAC, ventilation, which he believes is often overlooked in favor of flashier solutions. His company's protocol of testing on every customer visit, from first encounters to maintenance calls, has created a culture where technicians become comfortable discussing IAQ solutions based on actual data rather than assumptions.

The discussion transitions into ethical sales practices, a topic that resonates strongly in an industry where pressure to sell can sometimes conflict with customer needs. Brynn defines unethical sales as pressuring customers into products that won't benefit them or failing to provide complete information about benefits and consequences. His approach centers on thorough customer surveys to understand actual problems and budget constraints, followed by tying specific solutions to identified issues. This methodology puts the customer in control of decisions while positioning the contractor as a trusted advisor rather than a high-pressure salesperson. Brynn argues that price alone doesn't determine ethics - rather, it's the intent behind recommendations and the transparency of communication that matters most.

The final segment focuses on workforce development, an area where Brynn has found significant success. His company's registered apprenticeship program, developed through the Department of Labor, has become a competitive advantage in attracting talent while providing structured, in-house training. The program requires minimal cost beyond commitment to ethical treatment of apprentices and systematic tracking of their progress. Brynn's transition from contractor to educator demonstrates the growing need for comprehensive training programs that go beyond basic technical skills to include building science, customer service, and ethical business practices. His ongoing weekly training sessions focus on field trends and callback prevention, contributing to an impressive callback rate of less than 0.5%.
