Episode Details

Company culture isn’t a perk. It’s the operating system of your business.

In this episode of Titans of the Trades, Ryan Englin sits down with Trey McWilliams, third-generation HVAC contractor and CEO of Blue Cardinal Home Services Group, to unpack what it takes to build a culture that actually scales.

Trey grew up in the trades. He rebuilt his family HVAC business from the inside out, replaced almost the entire workforce, and turned it into a culture-driven organization that attracted talent, retained people, and created real opportunity. Today, he works with home services companies across the country as they prepare for growth, partnerships, and exit.

This conversation goes deep into the reality most owners face but rarely talk about: Culture drift. Leadership blind spots. Hiring the wrong way. Losing accountability as you grow.

Trey explains why culture always reflects the leader, why internal marketing matters more than external marketing, and how his “brand ambassador” role became the backbone of employee engagement, customer experience, and long-term loyalty.

If you lead an HVAC, plumbing, or construction company and want to scale without losing your people, this episode will challenge how you think about leadership, hiring, and accountability.
