Sam Myers is joined by Lee Canegaly from Retrotec’s tech support and dev team, along with Michael and Greg, to talk about what happens when blower door testing moves beyond code compliance and into industrial rooms, fire suppression systems, and strange building failures. The episode gets into enclosure integrity, blast-proof shelters, server rooms, and why field testing beats guessing every time.

Michael and Greg share stories from refineries, cigar bars, crawlspaces, and humid homes, showing how air leakage can affect safety, comfort, and millions of dollars in protected equipment.

Ben Walker and Sam Myers sit down with Brantley May to talk indoor air quality investigations, building forensics, and why you need both a contaminant and a pathway for a real problem. Brantley explains how blower doors, duct testing, and pressure diagnostics help prove where mold, smoke, dust, and odors actually enter a home. They also go over common misses from standard inspections, plus why better ventilation can be worth the energy tradeoff when health is on the line. If you want your houses to breathe right, share this with someone who still treats a blower door like a one time service.

Ben Walker and Sam Myers sit down with Jake Bruton to talk blower door testing, airtightness, and why data beats opinions every time. Jake explains why he tests multiple times during a build, what leak paths still surprise teams, and how those checks reduce risk and callbacks. They also get into vetting HVAC contractors for low load homes and why buy-in matters more than bravado. If you are serious about building better, share this with a builder who still “just knows” it’s tight.
