Jake Bruton welcomes Chris Miller from Central Energy Audits to discuss the importance of air sealing and performance testing in residential construction. They demonstrate a blower door test at a Kansas City project, emphasizing how tighter buildings reduce energy costs and improve comfort. Chris explains common pitfalls like poor insulation practices and missed air sealing, especially around top plates and basements. Jake highlights that testing throughout a project, not just at the end, helps catch issues early. Their shared message: building science professionals aren’t obstacles—they’re valuable partners who can save money, improve quality, and make homes more efficient and livable.
