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...

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...

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...

In this episode of the HVAC School podcast, Bryan welcomes back Jim to discuss the groundbreaking SureSwitch contactor technology from Copeland. This isn't just another incremental improvement - it's a complete reimagining of how contactors should work in modern HVAC systems. Jim brings his expertise and even demonstrates the technology with a special cutaway camera setup, giving listeners and viewers an inside look at this innovative solution. The conversation begins with the evolution of contactors in the HVAC industry, explaining how manufacturers moved backward from heavy-duty two-pole...

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...

In this comprehensive episode of the HVAC podcast, Bryan hosts an in-depth discussion about dehumidification technologies with two industry experts: David Schurk, National Sales Manager for Innovative Air Technologies, and Nikki Krueger from Santa Fe Products. The conversation explores the fundamental differences between compression refrigeration dehumidification and solid desiccant systems, providing valuable insights for HVAC professionals dealing with moisture control challenges. David Schurk brings 44 years of industry experience and serves as an ASHRAE Life Member and Distinguished...

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...

In this insightful episode of the HVAC School podcast, host Bryan sits down with Jennifer Butsch, Director of Regulatory Affairs at Copeland, to discuss the rapidly evolving regulatory environment affecting the HVAC industry. With eight years of experience at Copeland and a background spanning codes, standards, and regulatory affairs, Jennifer provides a unique perspective on the challenges and opportunities facing contractors, technicians, and manufacturers in today's market. The conversation begins with an in-depth look at the EPA's Technology Transition Rule and the recent shift from...

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...
info_outlineSharon Goepferich from Cool Air Products joins the podcast to discuss cutting-edge capacitor technology and innovative HVAC solutions in an introduction to the Sigma capacitor. Sharon brings a decade of industry experience, having worked extensively with capacitors and HVAC components while traveling across the country to educate technicians and contractors.
The conversation begins with a comprehensive breakdown of capacitor failures, addressing common misconceptions in the field. While manufacturing quality certainly plays a role in capacitor longevity, environmental factors like high temperatures and voltage disruptions—particularly common in markets like Florida with frequent lightning strikes—are primary contributors to failure. A crucial point emphasized is that failing capacitors typically cause compressor and motor failures, not the other way around. Many technicians incorrectly assume that a capacitor reading within tolerance is acceptable, but Bryan and Sharon clarify that even a degraded capacitor operating at reduced capacity can cause motors to run hotter and fail prematurely. This highlights the importance of proactive capacitor maintenance and replacement before complete failure occurs.
The episode's centerpiece is the discussion of the innovative Sigma capacitor system, which Sharon describes as being "designed on an airplane over whiskey." This modular pod system addresses a longstanding challenge for HVAC technicians: the impossibility of stocking every capacitor size on their trucks. The Sigma capacitor uses a stackable approach where technicians build the exact capacitance they need in the field using standardized components. The system operates on a simple rule: build the higher values first (typically compressor capacitance on top), then stack the lower values (fan capacitance) underneath. This approach maximizes truck inventory efficiency while minimizing the number of SKUs contractors need to manage, representing a middle ground between carrying extensive individual capacitor inventory and using traditional universal capacitors.
Cool Air Products extends beyond capacitors with their Combat P Trap system, an all-in-one condensate drain management solution that combines a shutoff valve, cleaning tab reservoir, and P-trap in a single unit. This product reflects the company's mission to solve everyday contractor problems in cost-effective ways. What makes Cool Air Products unique is their business model of helping industry insiders bring innovative ideas to market, providing support for patent processes, manufacturing connections, and funding. The Combat P Trap also demonstrates the company's commitment to giving back, as a portion of proceeds supports veterans—fitting since the product was designed by a veteran and serves an industry with significant veteran participation.
