  • Intro to The Sigma Capacitor

    Intro to The Sigma Capacitor
    Jun 19 2025
    Sharon 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.

  • What's up with Refrigerant & System Regulations w/ Copeland

    What's up with Refrigerant & System Regulations w/ Copeland
    Jun 18 2025
    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 R-410A to mildly flammable refrigerants like R-454B and R-32 as of January 1, 2025. Unlike previous refrigerant transitions that allowed for years of overlap, this transition was compressed into a much shorter timeframe due to building code requirements for the new mildly flammable refrigerants. While equipment delivery has gone relatively smoothly, the industry has faced significant challenges with refrigerant availability, particularly R-454B service gas. Jennifer discusses how OEMs have responded creatively, including pre-charging units with additional refrigerant and providing recovery cylinders as short-term solutions. The discussion also covers the ongoing debate about potentially returning to R-410A, which Jennifer argues wouldn't solve the current cost and availability challenges. She emphasizes that manufacturers have already invested heavily in transitioning their production lines and that rolling back would actually increase costs and timeline complications while moving in the wrong direction environmentally. The conversation touches on energy efficiency standards and the limitations of what can be changed under current legislation, noting that rolling back to pre-2023 efficiency levels would require Congressional action to revise the Energy Policy and Conservation Act. Jennifer and Bryan explore the complex world of tariffs and their impact on pricing stability, the potential defunding of Energy Star and what privatization might mean for the industry, and the challenges of regulatory fragmentation when federal oversight decreases and individual states create their own rules. The episode concludes with Jennifer's perspective on Copeland's philosophy of industry stewardship and practical advice for contractors on how to make their voices heard through trade associations and direct communication with legislators.

  • TXV Troubleshooting - Short #245

    TXV Troubleshooting - Short #245
    Jun 17 2025

    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 idea of the CFM your system is moving. Keep in mind that superheat and subcooling values can vary by system.

    Airflow problems and filter-drier restrictions may mimic failed TXV conditions. Ideally, the liquid line filter-drier will be located indoors, and you can check for a pressure drop across it by looking for temperature differentials. You need a full column of liquid going into the filter-drier, and you can use a thermal imaging camera to see the desuperheating, condensing, and subcooling phases inside the condenser coil.

    The TXV has a bulb that can be loose, improperly mounted, or improperly insulated; when there is an issue with the bulb, there will likely be low superheat. The bulb should be on a clean and [ideally] horizontal portion of the suction line, and it should be strapped with copper or stainless steel straps. Insulating the bulb is especially important when it's externally located and when low superheat or flood back is a concern.
