In this episode of the HVAC Know It All Business Edition Podcast, co-hosts Gary McCreadie and Furman Haynes from WorkHero sit down with Brynn Cooksey Sr, CEM, CMS, the Founder of Air Doctors Heating & Cooling and HVAC U (Building Scientists). They explore how building science can transform an HVAC business. Drawing from his background in the utility industry, Brynn explains why many contractors focus too much on equipment and not enough on understanding the home as a complete system. The conversation covers energy audits, customer trust, home performance testing, pricing strategies, and the business advantages of moving beyond simple equipment replacements. Brynn also shares practical advice for contractors looking to differentiate themselves through diagnostics, education, and problem-solving.
Brynn is a nationally recognized educator in the HVAC industry. Before entering the HVAC business, Brynn worked in the power and utilities sector, where he gained a deep understanding of energy generation, distribution, and efficiency.
