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.
