    EP190 Breathing Easy: Tackling Outdoor Contaminants in Indoor Spaces (October 2024)

    In this episode of the Building HVAC Science podcast, Eric Kaiser takes the lead in interviewing three guests from the ROCIS (Reducing Outdoor Contaminants in Indoor Spaces) initiative: Linda Wigington, Bill Collinge, and Rhett Major. Linda introduces ROCIS, sharing its 10-year mission to help participants monitor and improve indoor air quality, particularly in areas with poor outdoor air. The initiative, primarily focused in southwestern Pennsylvania, involves virtual cohorts where participants use low-cost monitors to track air quality and receive guidance to improve it. Bill Collinge discusses the differences between low-cost and high-end air quality monitors, explaining how ROCIS focuses on measuring particles and carbon dioxide. He describes how the cohort process helps participants compare outdoor air quality with indoor conditions, assessing how well homes filter and ventilate air. Bill also highlights how data collected across multiple homes helps identify patterns and informs recommendations for improving air quality, while Rhett Major explains the process of air handler interventions. By testing static pressure and airflow in HVAC systems, Rhett helps participants optimize their systems to run more efficiently and reduce energy consumption while improving air quality. The guests discuss key takeaways from the program, including the importance of filtration, proper HVAC system setup, and the potential health benefits of reducing particulate matter indoors. They emphasize the need for proper system commissioning and the challenges of engaging HVAC contractors in this work. In closing, the team shares their hopes to expand ROCIS principles and interventions beyond Pennsylvania and offer guidance to those interested in healthier, more energy-efficient homes.

    EP189 Breaking the Cycle: Huff's Journey to HVAC Excellence and Industry Change (September 2024)

    In the Building HVAC Science Podcast episode, hosts Bill and Eric are joined by Thomas "Huff" Hoffmaster, II to discuss his experiences transitioning from a technician to tech support and eventually into training and consulting. Huff shares his journey through the HVAC industry, beginning with his early exposure to sheet metal work through his family, moving into service because of his love for solving complex problems, and finally settling into tech support roles for major companies like Carrier and York. His passion for teaching and positively impacting the industry eventually led him to pursue freelance training and consulting, focusing on improving skills across the HVAC workforce. The conversation delves into the systemic issues within the HVAC industry, particularly around training, communication, and accountability. Huff emphasizes that many problems in HVAC installations stem from a lack of fundamental training and poor communication between sales, installation, and service teams. He points out how often HVAC systems are not installed according to best practices or adjusted properly to meet site-specific needs, leading to performance issues and callbacks. Huff also highlights the critical importance of technicians taking responsibility for their education, utilizing the wealth of resources available today, including tools like Measure Quick, which can elevate the consistency and accuracy of HVAC service work. Finally, Huff discusses the significance of addressing the root causes of issues rather than just the symptoms. He suggests that HVAC companies should develop protocols for analyzing callbacks to truly understand where mistakes originate—whether from lack of training, rushed installations, or poor management. By adopting a more systemic approach, companies can reduce errors, improve performance, and ultimately provide better service to their customers. Huff's insights encourage technicians and business owners alike to focus on quality, training, and effective communication to drive success in the HVAC industry.   Huff’s Linked: https://www.linkedin.com/in/thomas-huff-hoffmaster-ii-766b3a36/ Huff’s YouTube channel: https://www.youtube.com/@hvactalkwithhuff1379 Huff’s email: thoffmaster@hoffmastermechanical.com   This episode was recorded in September 2024.

    EP187 Revolutionizing Home Comfort: Marco Radocaj’s Balanced Approach to HVAC (September 2024)

    In this episode of the Building HVAC Science Podcast, Eric Kaiser is joined by Marco Radocaj from Balance HVAC, who shares insights into his HVAC journey. Marco starts by discussing his background, from an unexpected entry into the HVAC field through his father-in-law's air conditioning company to learning on the job as a new technician with no prior experience. His humorous story of hosing off a generator during his first day illustrates his initial lack of HVAC knowledge and the steep learning curve he faced. Marco explains the philosophy behind Balance HVAC, emphasizing their commitment to improving how homes are balanced regarding enclosure, occupants, and mechanical systems. He highlights the importance of addressing more than just the cooling function, aiming for a holistic approach to home comfort, where systems are measured and fine-tuned to optimize airflow and insulation. He shares his experiences transitioning from working in his family’s HVAC business to starting Balance HVAC, a new company focusing on thoughtful HVAC installation and attic restoration. Throughout the episode, Marco dives into attic restoration processes and how his team uses tools like thermal imaging and pressure balancing to ensure the homes they work on are more comfortable and efficient. He discusses the importance of communication with customers, sharing how Balance HVAC involves clients in the process by educating them on the science behind the solutions. The episode ends with Marco reflecting on his passion for elevating industry standards and his excitement about contributing to meaningful improvements in HVAC services. Marco’s Business: https://www.balance-hvac.com/ Marco was interviewed by R and R magazine in June 2024: https://www.randrmagonline.com/articles/90866-mold-and-the-need-for-attic-restoration More on Balance’s approach: We prioritize the thoughtful alignment of a home's enclosure and mechanical systems. Balance recognizes that homes built two decades ago were designed to "breathe," allowing for natural airflow to regulate temperature and moisture levels. However, modern construction methods and materials have shifted towards creating tighter homes that are not meant to breathe in the same way. This shift presents challenges, as features like energy-efficient windows, cooler attic environments due to improved roofing materials, and encapsulated attics can inadvertently lead to increased moisture, humidity, and environments conducive to mold growth. These issues can arise when homes are not properly aligned with modern building practices, potentially resulting in discomfort, poor indoor air quality, and health hazards. Marco's deep understanding of how homes are designed to perform allows Balance to address these challenges effectively. By identifying homes that are underperforming or straddling building codes, Balance can implement attic restorations that ensure optimal environmental control. This means creating spaces that are not only comfortable but also dry and healthy for occupants. Through a combination of optimal insulation techniques, strategic ventilation solutions, and moisture management strategies, Balance helps achieve the perfect balance between energy efficiency and indoor environmental quality. Their approach is tailored to each home's unique needs and budget, ensuring lasting improvements that enhance both comfort and peace of mind for homeowners.
