  • Learning and Teaching GRIT w/ Ty Branaman

    Learning and Teaching GRIT w/ Ty Branaman
    Jun 12 2025
    In this episode of the HVAC School podcast, host Bryan Orr and guest Ty Branaman have an in-depth, hands-on conversation about the philosophy, structure, and impact of GRIT Camps—workshops designed to introduce kids to the trades through immersive, practical experiences. The episode opens with reflections on a recent successful GRIT Camp in New Jersey, where both mentors and children gained new skills and confidence. Ty shares the excitement of seeing young participants, many of whom had never shown interest in school before, become deeply engaged in building, problem-solving, and learning from trades professionals. Parents noticed a newfound enthusiasm in their children, while mentors were invigorated by the opportunity to share their expertise and even learn new techniques alongside the kids. A central theme is the use of the Socratic method—teaching through curiosity, guided questions, and hands-on experimentation. Rather than providing step-by-step instructions, mentors encourage kids to make mistakes, ask questions, and discover solutions on their own. This approach fosters deeper understanding, builds confidence, and develops critical thinking skills. Bryan and Ty discuss the importance of meeting each learner where they are, allowing for individualized progress and ensuring that every participant, regardless of prior experience, leaves with a sense of accomplishment. The hosts also highlight how this method benefits mentors, many of whom find themselves learning and growing alongside the kids. GRIT Camps are designed like an “escape room” or adventure challenge. Each module—carpentry, electrical work, brazing, and more—presents real-world problems for kids to solve, emphasizing both safety and creativity. The hands-on activities are intentionally open-ended, allowing for flexibility and adaptation by different mentors and hosts. Safety is a recurring focus, with detailed discussions about best practices for working with tools, protective equipment, and managing risk, especially when introducing children to potentially hazardous tasks. The conversation also explores the broader societal impact of GRIT Camps, emphasizing the importance of restoring respect for hands-on skills and empowering both kids and mentors to build, fix, and create with confidence.

  • Band-Aids, Hacks, and Ethics - Short #244

    Band-Aids, Hacks, and Ethics - Short #244
    Jun 10 2025

    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. Patching condenser coils is an example of repair work that can be ethical. Some protocols say that the copper needs to be cut out and couplings need to be installed, but you can often patch tubing in areas where there isn't too much vibration. As always, you want to make sure that the system can hold pressure whenever you patch up a leak.

    The ethics question comes into play when the longevity of the equipment or repair is questionable. Bryan draws the line when the system has structural integrity issues, including damaged fins and severe corrosion. Beyond a certain point, patching a system up either won't be effective or will be an added expense without a payoff. Some companies also strongly favor sales over repairs, so some of those decisions may also come down to company policy.

    The key to ethical and successful "hack" work is situational awareness; you need to know which repairs you're capable of, your company's policies, and the client's needs. You ultimately need to make sure your actions are legal and safe for you and the client.

  • Why VRF Compressors Die w/ Roman

    Why VRF Compressors Die w/ Roman
    Jun 5 2025
    In this episode, Bryan and Roman dive deep into the world of Variable Refrigerant Flow (VRF) systems, focusing on the persistent issue of compressor failures. VRF technology has evolved, and it has seen a major rise in the North American market since the early 2010s. Roman shares his passion for VRF, tracing its origins back to 1982 and explaining how it earned the nickname “chiller killer” by replacing traditional chiller systems in large facilities like hotels, churches, and schools. However, with this rapid adoption came a troubling reputation: VRF systems became notorious for frequent compressor failures, prompting some institutions to revert to older technologies. There are three primary causes of compressor failure in VRF systems: oil lubrication issues, liquid refrigerant return, and electrical failures. VRF compressors are shipped with excess oil to account for the system’s extensive piping and multiple indoor units, but improper refrigerant charge—either overcharging or undercharging—can disrupt oil return and lead to gradual compressor death. They emphasize the importance of correct installation, accurate charge calculation, and diligent maintenance. Bryan adds that measuring discharge superheat is a key diagnostic tool: high discharge superheat with normal suction superheat signals poor lubrication and impending failure. The discussion then shifts to the dangers of liquid refrigerant returning to the compressor. Even small amounts can wash oil off the scroll plates, leading to metal-on-metal contact, galling, and eventual mechanical breakdown. Roman details the difference between high-pressure shell and low-pressure shell compressors, noting that VRF systems are more susceptible to operational flood back, which can cause elevated amp draws and catastrophic failure. They also highlight the role of contamination—such as copper shavings or sand from installation—which can damage expansion valves and lead to chronic flood back issues. Maintenance, including regular oil analysis and monitoring of expansion valve performance, is crucial for long-term reliability. Finally, the episode covers electrical failures, often the result of underlying mechanical issues rather than true electrical faults. The hosts advocate for using insulation resistance testing (megohmmeters) as a maintenance tool to track winding degradation over time. They stress that proper cleanup after a compressor failure is vital, recommending temporary filter dryers and oil analysis to mitigate contamination. The conversation closes with practical advice: always investigate the root cause of a compressor failure, communicate findings with clients, and prioritize best practices in installation and service to prevent repeat issues.
