EP256 The Woodstock of HVAC: Why This Symposium Hits Different With the TruTech Team (January 2026)
Building HVAC Science
Episode quotes: “What you put into this, you get out of this in multiples.” “It’s not about sales. It’s about learning, relationships, and leaving your ego at the door.” “Use AI responsibly, but keep the humans involved. The humans are what keep it honest.” In this episode of the Building HVAC Science Podcast, Eric Kaiser, Bill, and the TruTech Tools crew (Billy Spohn, Ginny Hebert, and Josh Crawley) recap their trip to the 7th Annual HVACR Training Symposium in Ocoee, Florida. Josh and Ginny share first-timer impressions: early-morning booth setup, instant attendee engagement,...

EP255 Beyond Manual J: The Heat Balance Future of Residential Load Calculations With Tony Amadio (December 2025)
Building HVAC Science
Notable quote from the episode: Make it as simple as possible, but not simpler. In this episode, Eric Kaiser sits down with mechanical engineer Tony Amadio, the founder of True Loads, to talk about what actually makes residential load calculations succeed or fail in the real world. Tony shares how his work is split between builders, architects, project managers, and HVAC contractors, and why the biggest early battle was simply getting people to trust results that pointed to smaller equipment. He explains how he quickly learned from feedback loops in production housing, including what happens...

EP254 Mold, Moisture, and Missed Details: Lessons From the Building Science Trenches With Kohta Ueno (January 2026)
Building HVAC Science
QUOTES from the episode: “Most building failures aren’t mysterious. They’re just ignored fundamentals.” “If you demand museum-level humidity, you’re no longer building a house. You’re building a museum.” “Moisture meters don’t solve problems. They show you patterns. The thinking solves the problem.” In this episode of the Building HVAC Science Podcast, Eric Kaiser is joined by Kohta Ueno, principal and co-owner of Building Science Corporation, for a wide-ranging discussion on building failures, moisture, HVAC, and the practical realities of diagnosing real-world...

EP253 The HVAC Trust Gap, and the Directory Built to Close It With Kevin R. Hart, Huff Hoffmaster & Darren Reuter (January 2026)
Building HVAC Science
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:...

EP252 The Perfection Trap in the Trades With Eric Kaiser (December 2025)
Building HVAC Science
Quotes from the episode: “Good enough isn’t a fixed point. It’s a moving target shaped by goals, expectations, and consequences.” “Perfection can push us forward, but it can also quietly pull us off track.” “If I delivered what I promised, in the time promised, using the resources promised, that is good enough for me.” “The real skill is knowing when extra effort adds value and when it just adds ego.” In this solo monologue episode, Eric Kaiser explores a deceptively simple question: Can good enough be perfect? Drawing on years of experience in the trades, Eric...

EP251 Innovation in HVAC: The Quiet Shifts That Matter Most With Bill Spohn (December 2025)
Building HVAC Science
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,...

EP250 Beyond the Equipment: Reflections on 250 Episodes of HVAC and Building Science with Eric and Bill (December 2025)
Building HVAC Science
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...
info_outlineQuotes by Brantley:
“Most moisture problems are a three-way dance—envelope, mechanicals, and the occupants.”
“Skim the light, don’t blast it. The right flashlight technique makes the invisible visible.”
“If you only understand one piece of the system, you’re solving 1/3 of the problem.”
Indoor environmental specialist Brantley May joins the show to unpack how he investigates moisture, mold, and air-quality problems through building forensics. Starting as a mold remediator in his family business, Brantley shifted to assessment work and now runs national investigations that pinpoint root causes—from envelope leaks and interstitial space connections to mechanical design and operation issues. He explains the value of “flashlight technique” (skimming light across surfaces to reveal early hyaline mold) and why good eyes, a light, and critical thinking are still the most important tools in the bag.
Brantley walks through his toolkit—manometers, blower doors, pressure pans, thermal imagers, moisture meters, anemometers/flow hoods, data loggers, and even a backup sling psychrometer—plus his new favorite screening instrument, the InstaScope, which provides real-time readings on particulates, mold/pollen, bacteria/virus, VOCs, and CO₂. Investigations culminate in a report and protocols for the envelope, mechanicals, and remediation, often requiring tight coordination across multiple trades. He stresses pre-drywall inspections, “red-pen” continuous air/thermal barrier checks, and long-term monitoring to verify theories—especially on complex modern designs where vented attics and interstitial spaces end up unintentionally connected.
A major theme: cross-disciplinary literacy. Most condensation/humidity problems stem from three interacting factors—envelope failure, mechanical failure, and occupant behavior—so HVAC pros must understand building science, and envelope pros must understand HVAC. Brantley shares how training (BPI, IICRC), mentorship, microscopy work (McCrone/Ochsner), and relentless curiosity shaped his practice. Watch for him at industry events (HVACR School Symposium, Build Show)—maybe even submitting a short BryX talk next time.
