Podcast appearances and mentions of bill spohn

Quotes from the episode: "Passed inspection is not the same as built correctly." "The best inspectors keep learning, because no one person masters every trade, every code, and every overlap." "Small defects do not stay small when they are hidden behind walls, ceilings, and warranty paperwork." In this episode of Building HVAC Science, Bill Spohn talks with Cy Porter of CYFY Home Inspections, an Arizona-based home inspector known for his blunt, high-energy social media videos that expose defects in new-construction homes. Cy specializes in one-year and two-year warranty inspections, helping homeowners identify issues missed at closing, including gas leaks, broken trusses, shower pan failures, air-sealing problems, roof defects, and code violations. His work sits at the intersection of construction quality, homeowner advocacy, and the sometimes uncomfortable gap between "passed inspection" and "actually built right." Cy explains how Arizona's implied warranty process gives homeowners a path to challenge legitimate construction defects, and how state investigators can issue written directives or citations when builders fail to correct violations. He also explains why patience, proper tool use, and cross-trade humility matter, especially when diagnosing small gas leaks, blower-door failures, and hidden installation mistakes. His stories reveal how small defects can become larger problems with safety, durability, comfort, and performance when no one catches them early. For HVAC, building performance, HERS©, and home inspection professionals, this conversation is a reminder that quality construction requires more than a signed-off checklist. It takes curiosity, documentation, collaboration, and the willingness to be corrected. Cy's approach may ruffle feathers, but his larger message is hard to ignore: homeowners deserve homes that meet the standards they were promised.

Quotes from the episode: "The tighter your envelope, the more attention you have to pay to ventilation and indoor air quality." "The acoustics of the ordinary rarely gets attention." "There's so much good work being done, so much data being collected, and oftentimes it doesn't leave the hard drive." "Noise annoyance may be one of the things people are most passionate about." In this episode of the Building HVAC Science Podcast, Bill Spohn welcomes Kieren McCord, a research scientist at Pacific Northwest National Laboratory, for a conversation about indoor environmental quality, acoustic comfort, and the often-overlooked benefits of building performance upgrades. Kieren shares her path from music and acoustics to building science, explaining how sound, comfort, air quality, thermal resilience, and human perception intersect in homes. The conversation explores how energy upgrades such as better windows, tighter envelopes, and improved insulation can create benefits beyond lower utility bills. Kieren explains how acoustic performance is measured, why low-frequency sound is difficult to block, how decibel weightings like dBA and dBZ work, and why human response to noise can be highly personal. She also discusses the promise and limitations of smartphone-based sound measurements, including the potential for making acoustic data collection more accessible to HERS© raters and home performance professionals. Kieren also shares details from recent field research on a Chicago window retrofit, in which triple-pane acoustic windows and careful installation resulted in a 35% reduction in whole-home air leakage. While the noise data is still being processed, the study aims to link measurable building improvements to homeowners' perceptions of comfort, quiet, smell, temperature, and overall livability. Her closing message is a call for more shared field data, more collaboration, and a stronger connection between academic research and the practical work being done every day by contractors, raters, and building performance professionals.

  QUOTES from the episode: "The people closest to the work often have the clearest view of what needs to change."   "Codes do not become practical until field experience finds its way into the conversation."   "Better data leads to better codes, and HERS® Raters are sitting on some of the most useful data in the industry."   "The future of energy codes will be shaped not only in committee rooms, but also in crawlspaces, attics, and blower door tests." In this episode of RESTalk, host Bill Spohn welcomes Nathan Kahre of the National Association of Home Builders, Alex Smith of the International Code Council, and Kris Stenger of ICC for a practical discussion on the 2027 IECC, the emerging 2030 framework, and how energy codes move from model language to real-world adoption. Together, they explain how the IECC is developed, how consensus committees and public comments shape the process, and why input from HERS® Raters, builders, subcontractors, code officials, and consumers matters. The conversation highlights several important 2027 IECC updates, including clearer blower-door testing provisions, expanded recognition of ANSI/RESNET®/ICC 380, tighter ERI targets, performance-path changes, improved fenestration values, expanded energy credits, and a new energy audit requirement for large additions. The guests also discuss how state and local adoption varies widely, from formal code councils and rulemaking processes to state-specific pathways like Texas HB 1736. Most importantly, Nathan, Alex, and Kris encourage HERS® Raters to get involved. Whether through local home builder associations, RESNET® program engagement, ICC interested-party lists, or future participation in the 2030 IECC subgroup, raters can bring field data, practical experience, and clarity to a process that increasingly depends on verified performance.

Quotes from the episode: "It's a solution to a problem people don't even know they have."   "Compliance is no longer just paperwork. It's becoming part of how smart contractors protect margin and keep access to refrigerant."   "What GPS did for traffic, shared HVAC documentation could do for equipment history, refrigerant tracking, and accountability."   In this episode of the Building HVAC Science podcast, Bill Spohn talks with Adam Dykstra of FM Hero about a part of the HVAC industry that often gets overlooked until it becomes a serious problem: refrigerant compliance, documentation, and tracking. Adam explains how FM Hero was built to help technicians, contractors, equipment owners, manufacturers, and eventually wholesalers manage the growing web of regulations tied to refrigerants, including Section 608, the AIM Act, and a patchwork of state-level rules. What sounds at first like a compliance tool turns out to be something bigger: a shared documentation platform that follows equipment, cylinders, and service history across the whole ecosystem.   Adam introduces the idea of the "Heroverse," a connected data environment where technicians can scan a unit nameplate, log service actions, track refrigerant movement, and build a portable service history over the course of their careers. Contractors gain visibility into field activity, equipment owners gain documentation they may now be legally required to have, and even manufacturers can see anonymized service history on their equipment in the field. The system is designed to fit real technician workflow rather than add paperwork, and the technician version is free to use.   The big takeaway is that refrigerant tracking is no longer just a back-office nuisance or an abstract EPA concern. With lower charge thresholds, more aggressive state rules, and likely future refrigerant supply constraints, documentation and recovery practices are becoming both a compliance issue and a business opportunity. Adam makes the case that contractors who get ahead of this can protect customers, strengthen retention, and even create a new profit center, all while helping reduce waste and preserve refrigerant supply for the future.   Adam's LinkedIn:https://www.linkedin.com/in/adam-dykstra/ FM Hero website: https://www.fmhero.com/FM Hero resource CenterL https://www.fmhero.com/resource-center/ Android app:https://play.google.com/store/apps/details?id=com.fmhero.mobile&hl=en iOS app: https://apps.apple.com/us/app/fmhero/id1570918942 This episode was recorded in March 2026.

Quotes from the episode: "The emotional side of letting go and the identity shift is something nobody really warns you about."   "Clarity is kindness, especially when the chips are down." "Intelligence gets beaten by emotional regulation and patience every day." (Tommy Mello)   This episode is a true "collab" between Building HVAC Science and HVAC School Podcasts, with Bill Spohn Sr. and Bill "Billy" Spohn Jr. (TruTech Tools) joining Bryan Orr and his dad Robert Orr (Kalos Services) to talk candidly about family business succession. They dig into the part nobody really warns you about: the emotional identity shift of letting go, moving from decision maker to advisor, and the weird tension of still being "the face" of the brand while your successor has to establish themselves.   From there, the conversation gets practical. The group compares how succession looks in a 24-person company versus a 400-person contractor, and why the fundamentals still rhyme: role clarity, accountability, and the right people in the right seats. Bill and Billy share how EOS helped "bake in" structure that made the handoff less chaotic, including accountability charts and more frequent performance conversations. Bryan and the Orrs add their lens on stewardship, culture, and doing right by people when the chips are down.   They wrap with advice for other family businesses: start earlier than you think, make a public commitment so you cannot quietly back out, seek outside counsel to keep your head from lying to you, and do not carry unresolved issues into family life. The final note lands on something bigger than succession itself: prepare for "what's next" so retirement does not become fading away, and keep relationships, forgiveness, and emotional regulation at the center if you want the business and the family to survive the transition   Bryan's LinkedIn:https://www.linkedin.com/in/bryanorrkalos/ Robert's LinkedIn:https://www.linkedin.com/in/rborr/ Billy's LinkedIn:https://www.linkedin.com/in/billy-spohn-jr-a06201a3/ Bill's LinkedIn:https://www.linkedin.com/in/billspohn/ Books we referenced: Traction By Gino Wickman RocketFuel by Gino Wickman & Mark Winters Succeeding.

EPISODE QUOTES "Anyone can install a heat pump, but if you don't understand how houses work, you're gambling with comfort."   "Our intake process is a pre-screen. We want customers who already want the heat pump." "Electrify everything is cute. Electrify efficiently is the job."   In this episode of the Building HVAC Science Podcast, Bill Spohn and Eric Kaiser talk with Larry Waters and Alex Sloan of Electrify My Home, a Bay Area contractor focused on efficient home electrification. Larry walks through his 43-year path in the trade, from early technical training and commercial HVAC work to residential, where he kept running into the same puzzle: systems that "worked" but didn't deliver comfort. A turning point came through BPI training and the building-science lens, which shifted his work from fixing equipment to fixing houses, and eventually led him to launch an electrification-only company when retirement plans and COVID reshuffled the deck.   Alex shares his own route, coming from incentive programs and building-science work, then meeting Larry as a homeowner customer, and later joining to help build business development and operations. Together, they describe an accidental but very real "visionary and integrator" pairing (EOS style), and how that partnership shaped a business model that prescreens customers: detailed online intake, a virtual assessment first, and an onsite visit only after budget alignment. Their goal is to spend time with people who already want the solution, not those who need convincing.   They dig into what "electrify efficiently" means in practice: load calculations on every job, job-type checklists, and designing around modulation, not just peak capacity. They also get candid about challenges, especially California utility pricing, old, leaky homes, and tricky heat pump water heater installations with space and wiring constraints. A standout concept is the "Watt diet," which plans electrification so homeowners can often avoid panel upgrades by using smarter equipment choices, circuit sharing, and load management. The episode closes with a clear takeaway from both guests: installing heat pumps without understanding houses, envelopes, and electrical realities is a recipe for disappointment. They also tease a future follow-up episode focused entirely on the history of electrification in the U.S. Regarding the National Home Performance Conference: New Contractor Discount - $825 - HVACSCIENCE Unique URL for your Show: http://nhpc26.org/building-hvac-sci Alex's LinkedIn: https://www.linkedin.com/in/alexjsloan/ Larry's LinkedIn: https://www.linkedin.com/in/larry-waters-31677b19/ Their company website: https://electrifymyhome.com/ Electrify Academy course calendar:https://emhlearn.com/calendar/?mcat=4# Electrify My Home YouTube Channel: www.youtube.com/@electrifymyhome      This episode was recorded in February 2026.

Episode Quotes: "Airflow isn't good. It's measured." "Most pushback isn't 'I won't.' It's 'I'm afraid I'll mess it up.'" "This is a people industry, by people, for people." JT Stewart joins Bill Spohn and Eric Kaiser to talk about how he went from long-term care nursing to HVAC, thanks to a red Chevy Ventura van, a ladder on top, and a "let's go fix some stuff" invitation. Today JT is an HVAC consultant at Slipstream, working with utilities and state programs to build real-world training that goes beyond "heat pumps are hot" and into the building-science fundamentals that actually make systems work. JT shares what his trainings look like in the wild, from half-day sessions to multi-day workshops, and how he designs them around the human side of HVAC. Homeowners are already uncomfortable when the system breaks, and techs can feel the same pressure when equipment and software change constantly. JT's take is that most resistance isn't stubbornness; it's uncertainty and fear of getting it wrong. He argues that confidence comes from structure: give techs time to learn, reduce guesswork, and use tools and processes that help them make good decisions when support is not available. The crew also gets into handling skeptical attendees and misinformation. JT's approach is to challenge people respectfully and bring it back to the homeowner, the contractor's long-term reputation, and the reality that this is a people industry. He encourages contractors to lean on manufacturer and distributor training, and he makes a strong case that homeowners also need better education on what questions to ask so "slick sales" do not replace proper design and commissioning. Bottom line: HVAC is getting cooler as a career because the knowledge, community, and training ecosystem are leveling up, and JT hopes that part isn't a fad.   JT's LinkedIn: https://www.linkedin.com/in/j-t-stewart/ His company: https://slipstreaminc.org/   This episode was recorded in February 2026.

QUOTES from the episode:   "You absolutely belong here. There are many paths into this industry, and there's room for everyone to thrive." - Cindy Zeis   "Patience, facts, and science always win the day." - Sharla Riead   "The future of women in building science is unlimited." - Nancy St. Hilaire   In this milestone 150th episode of RESTalk, host Bill Spohn marks Women's History Month by highlighting the voices of women from across the RESNET® community. Through a series of short conversations, industry leaders share how they entered the world of building science, the mentors who influenced their careers, and how the industry has evolved over time. Their stories reveal that there is no single path into the home performance and HERS® ecosystem. Some entered through construction, the mechanical trades, and hands-on field work, while others came through sustainability planning, academic programs, or early energy-auditing efforts dating back to energy crises of past decades. What they share is a passion for solving complex problems in buildings and translating technical building science into practical solutions that improve comfort, efficiency, durability, and affordability. The conversation also explores the experience of working in a traditionally male-dominated industry. Guests reflect on early moments of needing to prove their credibility, walking onto job sites where they were the only woman in the room, and overcoming stereotypes about fieldwork. At the same time, they highlight the strong mentorship, collaboration, and respect that characterize the RESNET® network. Many have seen meaningful progress over the years, with more women becoming HERS raters, modelers, quality assurance professionals, and industry leaders. Looking ahead, the guests point to one of the biggest remaining barriers: visibility. Many people simply do not realize that building science exists as a career path. Their advice to the next generation is to stay curious, seek hands-on experience, build strong communication skills, and ground their work in solid science and ethics. As building performance becomes increasingly interdisciplinary, blending field diagnostics, data, standards, and software, the opportunities for women to influence and lead the industry are expanding rapidly. Their closing reflections capture the spirit of the episode: the future of women in building science is impactful, influential, and ultimately unlimited.   Guests this episode: Cindy Zeis, Technical Director with PSD https://www.linkedin.com/in/cindyzeis/   Julie Christesen, Chief Administrative Officer/Building Scientist with ES Green & Co. https://www.linkedin.com/in/julie-conn-christesen/   Nancy St. Hilaire, Co-owner of Builder i Group https://www.linkedin.com/in/nancy-st-hilaire-59161121/   Laurel Elam, Sr. Director Business and Standards Development for RESNET https://www.linkedin.com/in/laurel-elam-5404817/   Sharla Riead, Lead Instructor at the Energy Smart Institute https://www.linkedin.com/in/sharla-riead/ To the RESNET® community, we hear you and want to engage.

Quotes from the episode:   "Better isn't a goal, it's a direction." "HVAC can feel like a house of mirrors for homeowners, and the cure is transparency plus measured results." "We're not trying to find the perfect contractor. We're trying to find the contractor who keeps learning and won't get complacent." In this episode of the Building HVAC Science Podcast, Eric Kaiser flips the script and brings Bill Spohn on as a guest alongside Kevin Hart from Better HVAC and Darren Reuter and Huff Hoffmaster from Rewiring America. The group lays out a shared problem: homeowners face a significant information disadvantage when buying HVAC, often making a five-figure decision with no easy way to verify quality beyond marketing, promises, or price. That gap leads to mistrust, inconsistent outcomes, and too many "box swaps" that miss sizing, duct performance, commissioning, and homeowner education. Better HVAC exists to tip the odds back toward the homeowner by connecting people to contractors and individuals who commit to doing measured, commissioned work, and by aggregating trusted educational resources in one place. Rewiring America adds the consumer education and electrification planning layer, plus a push to scale adoption responsibly, with real contractor standards behind it. The partnership ties those strengths together: instead of building separate directories, they align on a shared pledge and a badging approach that helps homeowners and peers filter for contractors who are trained, insured, licensed, and willing to follow best practices, especially for heat pumps and whole-home electrification journeys that also include weatherization and energy auditing.   Rewiring America's website: https://www.rewiringamerica.org/ BetterHVAC website:https://betterhvac.org/ BetterHVAC Pledge: https://betterhvac.org/pledge   Huff's LinkedIn :https://www.linkedin.com/in/thomas-huff-hoffmaster-ii-766b3a36/ Kevin's LinkedIn:https://www.linkedin.com/in/kevinrhart/ Darren's LinkedIn:https://www.linkedin.com/in/darrenreuter98/ Bill's LinkedIn: https://www.linkedin.com/in/billspohn/   Corbett's list: https://homediagnosis.tv/hvac-installers     This episode was recorded in January 2026  

QUOTES from the episode: "What raters do makes the difference. Supporting them protects the credibility of the entire ecosystem." "Energy and water performance are not abstract. They are measurable, verifiable, and they matter to families." "My role is to protect what works, listen carefully, and help RESNET adapt without losing what makes it special." In the first RESTalk episode of 2026, Bill Spohn welcomes Shelby Gatlin, the new Executive Director of RESNET©, for a thoughtful conversation about leadership, credibility, and the future of home energy ratings. Shelby shares her professional path from conservation-focused work and regulatory advocacy into the residential energy efficiency space, including years spent navigating operational growth and industry change. Shelby explains why RESNET©'s voluntary standards, third-party verification, and ecosystem of trust matter now more than ever, especially as affordability, comfort, and long-term household costs take center stage. She emphasizes that energy and water performance are not abstract concepts, but measurable outcomes that directly impact homeowners. Throughout the discussion, Shelby underscores the critical role of raters and providers in protecting the integrity and credibility of RESNET© programs. Looking ahead, Shelby outlines her leadership approach: build on what already works, listen closely to stakeholders, modernize systems where clarity and transparency are needed, and preserve what makes RESNET© unique.

Quotes from the Episode: "Innovation in HVAC isn't one big breakthrough. It's a series of quieter shifts that slowly change how we work." "The future of HVAC depends on the people who measure, verify, and continuously improve." "Collecting data is getting easier. Interpreting it well is where the real value lives." "True innovation isn't about chasing trends. It's about reducing uncertainty and delivering better outcomes." "Homes aren't a collection of parts. They're systems, and HVAC sits right in the middle of that system."   In this solo episode, Bill Spohn reflects on how innovation in HVAC really happens, not through one flashy breakthrough, but through a series of quieter, incremental shifts that compound over time. Drawing from 250 episodes of conversations on the Building HVAC Science podcast, Bill reframes innovation as a mindset grounded in measurement, feedback, and systems thinking rather than just new equipment.   Bill walks through key patterns he has observed across the industry, including the shift from equipment-focused thinking to system-level performance, the rise of connected and cloud-based field tools, and the growing role of software in interpreting data rather than just collecting it. He highlights how smart tools, real-time diagnostics, commissioning workflows, and platforms like MeasureQuick have changed troubleshooting, accountability, and profitability for contractors who embrace them.   The episode also explores major themes shaping the future of HVAC: electrification and heat pumps, dual-fuel strategies, improved load calculations and design software, smarter controls and commissioning, and the rapid evolution of indoor air quality from a niche topic to a core expectation. Bill emphasizes the increasing integration of HVAC with building science, ventilation, moisture, and enclosure performance, and points to contractors who are thriving by treating homes as complete systems. He closes by reinforcing that true innovation is about reducing uncertainty, improving outcomes, and supporting continuous learning, all while encouraging listeners to explore BetterHVAC as a growing nonprofit resource for contractors and homeowners alike.   This episode was recorded in December 2025.

Quotes from the Episode: "Good building systems don't start with equipment—they start with a plan and a thoughtful process." "Most comfort problems aren't equipment problems; they're building problems we haven't taken the time to understand." "If even one episode helps someone take the next step in their career, then it's all been worth it." Episode 250 of the Building HVAC Science Podcast flips the script. Instead of Bill Spohn and Eric Kaiser doing the interviewing, TruTech Tools' Senior Marketing Manager Ginny Hebert steps into the host seat to reflect on 250 episodes of conversations about comfort, buildings, and the people who work on them. What follows is an honest, thoughtful look back at what the show has uncovered—not just about HVAC systems, but about how people learn, think, and grow within the industry. Bill and Eric reflect on how their understanding of comfort has evolved, especially regarding concepts such as heat transfer, mean radiant temperature, air sealing, and treating the house as a system rather than a collection of parts. They discuss how many "equipment problems" are actually building or design problems, and why taking time to think—really think—about a problem is often the most valuable (and most overlooked) practice in the trade. The conversation highlights how technology, connected tools, and computing power have improved diagnostics, while also reinforcing that good outcomes still depend on mindset and process. The episode also looks forward. From normalizing system testing and indoor air quality assessments to improving how comfort is predicted and communicated, Bill and Eric share what they hope will become everyday practice over the next decade. Above all, this milestone episode is a thank-you to listeners, guests, and the broader HVAC and building science community—for staying curious, open-minded, and committed to doing better work for the people who live in the buildings we touch.

"Get mad at the problem, not the person. When people feel safe, they'll actually bring you the real issues." - Bill Spohn "We're woven into the fabric of this industry. The industry made me—so in a way, it owns me." - Bill Spohn "What we have to learn to do, we learn by doing." - Aristotle In this episode, Eric turns the mic around and interviews his co-host, Bill Spohn, about the evolution of TruTech Tools, his leadership philosophy, and why he's shifting from "Chief Executive Officer" to "Chief Education Officer." Bill traces the roots of TruTech back to late 2006, when a suggestion at a Testo Christmas party planted the seed for an online test-instrument business that launched in April 2007. He talks about how TruTech has become "woven into the fabric of the industry," helping connect HVAC and building performance pros while focusing on specialty tools, education, and best practices. A big chunk of the conversation is about people: attracting and retaining the right employees, and running the business through the lens of core values. Bill and Eric walk through TruTech's four core values—Do the Right Thing, Be a Team Player, Get It Done, and Be Attentive—and how they were distilled from nearly 80 traits the leadership team admired in their co-workers. Bill explains how these values show up in hiring (situational questions), in problem-solving (getting mad at the problem, not the person, and using the "five whys"), and in daily decisions about how to treat customers and each other. Bill also opens up about his intentional five-year transition plan out of day-to-day leadership and into a more advisory and educational role, including transferring ownership and the President role to his son. He shares why he didn't want to be the owner who leaves on a stretcher—or the one who keeps wandering back in and undermining the next generation. Instead, he's leaning into training the team, mentoring startups, and building out the Better HVAC directory as a free resource for contractors and consumers. Along the way, he and Eric talk about the "comfort industry" as a whole, the blending of HVAC and building performance, the importance of passing down institutional knowledge, and even Bill's side quest to learn rock guitar and someday join the Building Science Boogie Band.   This episode was recorded in November 2025.  

QUOTES: “We created the CIRRUS Low Carbon program to speak to developers' pocketbooks — build a better building, and you get a better rate.” — Tricia Baker “Early design is peace of mind — it saves you a buck or two and a lot of headaches later.” — Karl Peer In this episode of RESTalk, host Bill Spohn is joined by Tricia Baker, Senior Vice President of Strategy and Impact at PACE Equity, and Karl Peer, an in-house engineer with deep experience in HERS ratings and energy modeling. Together, they unpack the power of C-PACE (Commercial Property Assessed Clean Energy) financing — a state-enabled program that helps developers and building owners access long-term, low-cost private capital for sustainable building upgrades and construction. Tricia introduces CIRRUS Low Carbon, a unique PACE Equity program that rewards better-performing buildings with lower interest rates. Buildings that meet a HERS score of 55 or better automatically qualify for discounted financing, offering developers meaningful savings — often 50 basis points lower than standard rates. She emphasizes how this program directly links building performance to financial incentive, creating a clear economic reason to pursue higher-efficiency, lower-carbon projects. Karl brings the technical depth, explaining how in-house engineering and RESNET© collaboration ensure rigorous validation. He describes case studies ranging from multifamily buildings in California to resilient coastal redevelopment in Florida, where C-PACE funding supported both energy efficiency and storm-hardening measures. Together, Tricia and Karl illustrate how early engagement in the design process yields the best outcomes — “early design is peace of mind,” Karl says — showing how this innovative financing mechanism can drive sustainable change while improving property value and financial performance.
